Sony Projection TV Red Line Repair Guide (Blue & Green, too!) Retrace Lines

A couple of weeks ago, red lines or bands of red color (they can occur in green and blue as well) started showing up on my Sony Rear Projection HDTV (High-definition 16:9 aspect ratio, model KP-51HW40) when watch movies. It was very noticeable when watching dark scenes or black transition screens during the films. Over a couple of weeks, it got a little worse until it started looking like this.

Red lines on Projection TV with red curved bands know as retrace lines

Not so good to have the red lines like that. While some people have complained about their Sony televisions and specifically the rear-projection units, mine has been almost flawless for the 5 1/2 years I have had it. This happened once before, after about 3-years of use and my BestBuy extended warranty on the TV was up. According to several sites, the problem is with the convergence via the voltage on the color ray gun tubes that get out of adjustment. They are also known as retrace lines

Sony wanted between $150-$300 to diagnose and fix the television -- instead I was able to complete this repair in less than 15 minutes!

Update: I have now received over three hundred comments on this fix in addition several hundred emails -- saving visitors over $250k in Sony TV repairs, wow! In many cases, people have wanted to send me something for helping them fix their Sony Projection TV. This type of post is something Sony should make public -- I was just an end user consumer (like you) with no previous TV repair experience. The way you could help me most is that you have a website, blog, Facebook, or MySpace account and would consider posting a link to this site, I would greatly appreciate that! Otherwise, if you really feel compelled send me something, you can always Paypal me at ken.hanscom@gmail.com.

Best of luck!

Since I had been through the routine once more and I was sure others are running into this issue, I am posting a how-to-guide / repair manual for the Sony Rear Projection Television. All you need to complete this guide is one flat-head screwdriver and one Phillips screwdriver as well as a delicate touch.

Please let me know with a comment below if this solution works for you. If this solution is not the problem you have, please be sure to check our sponsors on the right to see if they apply to your needs.

1. See the ugly red color bands on the television set? These can also occur in blue and green. We're going to fix these!

2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.
Shows the location of the front screws to access the Red, Green, and Blue voltage and convergence adjustments

3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.

4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.
Once the cover is removed you the cabling is displayed

5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.
To access the Red, Blue, and Green guns or rays, you need to remove the board covering it with four screws

6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.
This is a shot of all the electronics in your Sony HD Television

7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.
The adjustment console, the bottom adjustments are for your color voltages

Looking for the service manual for your KP-51HW40 that has additional information on it in addition to solving the retrace lines? It can be found here: http://www.northern.ca/projects/sonytv/KP-51HW40%20Service%20Manual.pdf

Ken Hanscom said...

Great news! Glad my little blog here could help you out. It's nice to know that the fix is so easy and works for a lot of the Sony HD TVs!

Anonymous said...

Ken, I can't thank you enough for sharing this information. More importantly, thank you so much on taking the time to put pics in along with detailed directions. It worked like a charm and this article is forever stored in my entertainment center. If only Sony were so thoughtful. You rock!

Do you adjust then turn on the TV or do you adjust while the TV is on? Thanks!

Ken Hanscom said...

The TV needs to be turned on it make sure you do not turn it too far, as well as fine tune the adjustment.

Chad said...

Wow that is awesome!! Great tutorial. Tks so much. saved me money and gonna keep the wife off me now.

We had it with green. Your instructions worked perfectly. thanks Ken

Ken Hanscom said...

Great to hear, nothing like saving a Sony Service call!

The instructions for repairing the "Green" arch lines on my Sony HDTV worked to perfection. The repair shop wanted to charge me $540 to replace a lens.

amber said...

Thank you so much for this info and the manual!! We have been looking into solving this issue for over a year (didnt want to spend the mucho buckos they wanted to repair it)!! I'll let you know how it worked once my fiance' tries it.

Anonymous said...

great illustrations
My tv started with blue arches and a couple weeks later started to flash blue then tv turned off.
Did your tv turn off as well?
tried the adjustment but tv still turns off
any other advise?
really appreciate your time and photos
thanks

Ken Hanscom said...

I did not have the TV turning off issue like you did. Mine was retracing lines only. Is your LED blinking after the TV turns off? If so, I would recommend looking at the service manual in the first comment to see what the self diagnosis is stating as the problem.

Anonymous said...

Ken,

Wow!! I have had red lines for over a year and just chalked it up to TV going bad. Very light green lines showed up a couple months ago and this morning I turned on TV and it was all red. After a bout 10 min. it slowly went back to normal but I was sure I would be shopping for a new TV by noon. Found your blog and in 10 - 15 min. my TV was good as new. Can't thank you enough for taking the time you did to be so helpful!

GREAT support (detailed and illustrated)... it worked PERFECTLY.... thank you....

This worked perfectly for me. Thanks for the detailed pictures, they really make this repair easy. I was having the issue of my TV fading to a blue screen after about 20 seconds of power and then it would shut itself off. The standby light would then flash series of eight times. Service was quoted as $200-$600 to fix this issue. Can't thank you enough

Anonymous said...

Ken,
Thank you!! We've had this problem for over 1 year. Previous web searches for solutions and an inquiry to the Sony help line netted us nothing. We took 15 minutes to adjust our red and green lines and have the best picture that we've ever had on this television. We were just getting ready to purchase a new tv, so I figure we saved about $2000. Thanks again.

Anonymous said...

THANK YOU! Have been having "red lines" in concentric circles (half circles?) for several months now, was afraid TV was going bad and would have to replace, or big repair bill.

Found your site, and within 15 minutes my picture was perfect again! Thank you so very much!

Anonymous said...

This procedure worked like a champ!! I thank you for the time you took to put this information out! I had Red lines for months, and then it went completely red. After trying your instructions, I had it fixed in a matter of seconds. You are correct, it requires very little turning of the adjustment knob.
Thanks again!!!

Thank You Ken

I had my tv adjusted in OCT (last month of the extended warrenty) and started to get similar blue/ green lines again. I know it was an easy fix, but did not know how the repairman did it. Now I do and I fixed it today. Thanks again.

Anonymous said...

Thank you so much for the info. I just started getting the red lines a few weeks agao and thought I'd be facing a big repair bill or just try to ignore the lines which is impossibe for me. Directions were right on.

Anonymous said...

YOU ROCK! Thank you so much for posting how to fix the Sony red line issue. I have had red lines on my TV for close to 9 months and I was actually looking today at new TV's. You saved me over $3500 for not having to buy a new TV. You the man!!!

You are awesome man.

Hi,

Have the KP57wv600 and had the green line issues. Fixed that 2 weeks ago. Now I tried to tweak it for too much red and TV shuts off in a few seconds. I get a light blue screen and then nothing.

I did see some arching, thinking voltage issue, and then it shut itself down.

Any thoughts on a fix.

Much appreciated.

Dave

Jason said...

Freakin awesome. My problem was different than yours, I had the light flashing 5 times. My picture would come up blue with some blue lines for about 10 seconds and the picture would turn off. This totally solved my problem. We live in the country and couldn't even get a Sony tech to come to our home. From reading around lots of people are having this problem and need to know about this.
Thanks Ken!

Victor said...

I saw your instructions yesterday, tried them today, and the TV is back to normal. I had been living with the dreaded red lines for over 2 years. Fixed the red lines, and adjusted the blue lines too. Simple fix! Thanks a lot.

Just bought a KP-57WS500 with the same problem. The screen was green and turned off after a few seconds.

Turned the green control 1/32 of a turn counter clockwise and got the tv to stay on. then noticed the blue show up. Turned that controll 1/64 of a turn counter clockwise. Now I have a perfect picture. Thanks a bunch!!!

I have a Sony KP-51WS500 and started seeing blue lines on dark scenes. I adjusted my blue one and it went away. Thanks for posting this fix. I had to do it late at night while my wife was asleep, cause if she saw me taking the TV apart, I would have gotten yelled at. Also, it is easier to make the adjustment with no ambient light. Thanks again.

You fixed my television... or, at least, taught me how to fix it. Thank you. Thank you. Thank you.

I had red lines on my sony tv for well over a year. And after the simplest 10-15 minute exercise, there completely gone and the tv looks good as new. Thanks a lot Ken!!

Jeff said...

thank you so much

I've been living with the green lines for months--Like others I thought it was at the very least an expensive repair or a replacement set.

I'm electronically challenged so I was not sure I wanted to take the set apart. It took longer to take the screws out of the front than it did to adjust the lines.

What terrific information--thank you once again
Jeff

Hi I am having the same problem except my TV has white/gray retrace lines in it. Not a color. Any help here? Thanks

Anonymous said...

This really does work. Thank you so much for the pictures of how to do this. I was able to adjust the green and remove the lines from my picture. It was a simple solution for a problem that I thought was major. Even after contacting Sony I didn't get any answer. I am really glad I found this. Being a female I was scared to try at first but I said what the heck and did it on my own. Thanks again!!!

Dose anyone knows how to replace a screen on 53HS10? I broke the screen; however TV still works fine.

Ken Hanscom said...

Unfortuantely I do not know where you can get a replacement screen for your 53HS10 television. I did some quick Google searching and did not come up with too much. Hopefully this is not a case of you Nintendo Wii Remote (Wimote) going through the TV!

Best of luck on it and perhaps you should contact Sony Customer Support (don't expect much) or a local TV shop to see if they have any suggestions for ordering the parts.

Thank you so much Ken, Was at a friends house Friday night and the 57" sony was turning on ok, but in seconds the blue tube would make ticking noise and flicker. I looked in the back and said I would return tomorrow after looking at internet. You are great, pictures and all. I made a red mark on the pot for location reasons and dialed each one down 1/32 and problem gone, even the lines problem, I did not know about.Then we watched the movie 300, thanks to you!

Anonymous said...

I have the problem with the red lines. It's not as bad as the picture posted here. The red lines ghost about a inch to right of the image/text on the screen. With the TV on when I turn the red screw to the left, I don't see any change. But sometimes when I turn the TV off then on after I rotate the screw, the red lines disappear. About a minute after the red lines disappear I see them come back slowly. I tried every rotation and the red lines always come back. Btw, do I only change the bottom row screws? A little off topic, do you know anything about what the flash focus does.

Ken Hanscom said...

If you are interested in the values of the LED trouble / flashing lights on your Sony TV, I have updated a posting here: http://www.somelifeblog.com/2007/08/sony-tv-led-blinking-codes-what-does-it.html

WOW -- another positive effect of the internet - I have a 57 inch - used you manual, red lines gone also saw a blue line - fixed that -

still have the tv flash bright everyonce in a great while (not near the frequency as before I adjusted) -- but I'll go back and tweek if necessary --

thanks again

Your fix was absolutely great!!!!!!

We bought our Sony 57 inch TV about 6 years ago, and have never had a problem with it, and were dismayed when it started showing red lines as we thought we would have to invest a pile of money to replace it.

I had been looking on the web for several months to try and find a fix for it that I could do, with little or no luck.

In looking at the date of your post, I see that it was pretty new, and so, I was excited to finally not only locate a fix, but one with pictures, and which was presented in a step by step fashion.

It worked 100% and was EXACTLY what I was looking for !!!!!

I am so thankful to you for this fix.

If Sony was smart, they should be offering you a position as one of the VP's for Customer Service right now.

Thank you again !!!!!

Help, I want to fix the red lines appearing on my sony model # KP-53V80 using your idea BUT I can't get the cover off the front! does anyone know how to do this without breaking the panel?

Anonymous said...

Ken,
Thank you so much for the instructions to get rid of the green horizontal
lines on my Sony KP51WS500. I followed your instructions, I carefully turn
the adjustment screw about 1/8 turn counter clockwise and the lines were
gone! your instructions and pictures were detailed and easy to follow.

I had contacted Sony for some assistances, they gave me phone numbers of
local repair services. I contacted one of them to get an estimate, they
quoted me $75.00 for a service call and approximately $150.00 for repairs
for a total of $225.00. I took me 10 minutes to fix it and zero $.

Thank you!!!

kp-57wv700 here and i can't figure out how the front panel/cover comes off.
Anyone have any idea how the come off?
Each side has 5 screws, once removed the side become loose but it feels like something is still holding on.
I've searched all around and i don't see any other screws holding it.
Thanks for any help.

I have a 2002 Sony rear projection TV. The TV suddenly went to an orange screen and then would shut off after 10 seconds. I contacted the nearest Sony repair service and told him of the problem. He said it was a $700+ repair. My wife and I decided to trash the set and purchase a new one which of course is thousands. I wheeled it into the garage and before getting rid of it, I went online to research a bit first. My service manager for my company also went online and found your site. We followed your instruction to adjust the red color screw and instantly had the TV back into perfect condition! There is no way we could have figured this problem out without your valuable advice and instruction with the photos. I am sure that you have saved many people thousands of dollars and I wanted to thank you. It’s certainly nice to have people like yourself helping others and preventing us from getting ripped off or having to replace a TV for a simple adjustment. Of course the manufacturer does not include this simple fix in their troubleshooting info. Gee, I wonder why.

i just wanted to say a big thank you as well. this saturday my 2 year old sony kdp51ws655 went to a blue screen..... went black while sound still played for about 10 seconds and then shut off. The LED lights on the bottom where it said stand by flashed about 8-10 times. I then would turn the set back on and it would stay on for about 20 seconds, then repeat the same process. Finaly after about 1 hour, the set started to go to blue then went back to a normal look with sudden blue flashes and some color change. I thought to myself... what should i do? So i probably did what most people do when there set goes caput before the first weekends of college football, I called sony and they said that it was possibly a bulb replacement needed or it could possible be a job that would cost me around 400-500 to fix including labor. So i was obviously upset. Then i guess you know the rest of the story, just by luck i found your site on a google search and turned the blue screw just a bit to the right and everything is perfect. What a great person you are. As mentioned by other people, it is good to know that there are good people out there that are not in it to take money from everyone for a quick 10 minute fix. On a teachers salary it makes a difference. Thanks again.

Thanks much for all the info. I have a 53HS10 that is experiencing the following: (a) the flashing on/off of the picture when watching on video 5 with a high-def input from a PS3, (b) a slow roll of white/greenish lines while showing the feed from video 5/high-def input (these lines do not occur while showing in standard input), and (c), five blinks on the timer/standby indicator. Overall, the picture in HD mode has been less than HD quality for the past six months, but it neved flashed on and off until a week or so ago. So, when I read the various posts, I thought I would try adjusting the R/G/B voltage screws to see if it would solve all the issues. I would say that the overall focus appears to have improved, but the rolling lines are still prevalent and the timer/standby light is still flashing 5 times. I have periodically noticed that a low humming noise is more obvious when the TV is showing the video 5/high-def input.

Any other suggestions or experiences?

Thank you so much. You gave me the knowledge to repair my KP51WS500. I have loved my Sony for more than four years, but over the last six months or so, I've been afraid of a major repair bill, thanks to those elliptical red lines.

I just fixed my television using your suggestion. Thank you very much. You are my hero (for at least one night).

Anonymous said...

As a follow-up to my post yesterday regarding the 53KS10, I turned the TV off overnight and this morning, lo and behold, the timer/standby light is no longer blinking and the screen is not turning on and off while displaying the video 5/high-def input. So, I will keep my fingers crossed and hope the R/G/B adjustments have some long lasting effects after letting the TV "rest".

Thanks so much. I'll keep checking the blog in the event other ideas or suggestions are posted.

Dear Ken,
I was having trouble with my t.v for the past couple of months. I was getting red and blue lines and then the whole screen turned red. I thought I needed to get a new t.v. and it was only 5 1/2 years old. It was a sony projection t.v. model # KP-57HW40. Then i found your site and tried your suggestion and it worked.If it doesnt continue to stay like this do you recomend replacing the black box? Thank you so much!!! I really appreciate it!!!

Ken Hanscom said...

Daniel,

Not sure. This has actually worked great for me twice now. Hopefully the TV will make it a couple more years before I really need a new one!

-Ken

David said...

Ken:

Thanks!

Worked great! Once the lines were fixed we noticed that the picture in general was much clearer.

I really appreciate how much effort you put into this.

I'm so happy to find this blog. It seems our KP46WT510 is having this problem. I'll be showing this to my husband when het gets home from work. I hope we can figure out how to get the thing open ;-). Ours has the red arch going on on the left side of the screen where it dips down and then there's kind of a red shadow of everything on the screen including images and words. Hopefully this method will work for us. Thanks so much. I'll update after we try it.

Excellent! I had faint blue lines at the end of my Best Buy extended service contract, and they "fixed" them. But in the 18 months since then, they've come back and stronger than before, and with a blue cast on what should be a black screen.

So I did some web searching yesterday, and found your blog. Today it's fixed. Barely touched the blue pot and wow - retrace lines and cast gone! Thanks!

Ken,

I had the green lines and the shutting down and was able to fix those two problems with your help. Thanks. The only thing i can't get rid of is the entire screen has a green haze, no lines, but you can slightly see the picture through the green tint. Should i still play with the green adjustment? or is there another problem?

Nick said...

I cannot thank you enough for this posting. You saved me hundreds of dollars, and now my picture is better than it ever was. I have had this TV for 5 years, and had arching blue lines after about a year that were getting more prevalent and abundant as the years went on. I now have a perfect picture. Thanks again.

Dan said...

Ken It worked great I have had the red lines in the tv since last year and just thought it would be too expesive to fix I even talked my wife into letting me look into new TVs

But i fixed it myself looks great again. I live in the woods and It would take alot to get a service tech out here I wish sony would have be more helpful thanks

thanks for your posting, it sounds like you are really helping a bunch of sony tv watchers. My tv had the red lines and I too was real close to loading it up and taking to service center, maybe I should send you a gift card instead?

Help..my problem is no picture at all when I turn the TV (KP51WS500)on but a red light flashes quickly for 5 times and then pauses for 2 seconds and then the cycle continues. The red flashing light comes on wher it says "Timer/Stand By". Service said over the phone that it would cost $500 to fix.

Bob C said...

Thank you so much, you were exactly right and it got rid of my red and blue lines. This had happened once before on my Sony 60 inch rear projection TV and the repairman replaced a tube. Fortunately it was under warranty then, I am sure this fix just saved me a ton of money. Thanks again, Bob

Ken...you are truly an awesome person, helping us like this. I was having red line problems with my Sony KDP-57XBR2, and saw your post with instructions and pictures on how to fix it, and tried it. IT WORKED, BEAUTIFULLY!! HAD THE BEST PICTURE EVER AFTER ADJUSTING THE RED SCREW. Was shouting with joy. But then...my TV shut-off after about 2 hours of playing, and now I can't get it to come back on??? Adjusted the red again, but it still won't come back on. Sony wants to charge me $800 to fix it...says the red bulb needs to be replaced??? Do you know anyone who has repaired/replaced this on their own? REALLY APPRECIATE YOUR HELP!!

Ken,
Thanks for a superior fix. This saved my inlaws a substantial amount on a new big screen television. I'm speechless, and it's so easy to do. We had red and green lines appear right before my deployment, and against their wishes, my inlaws did not go get a new set because I said I could fix theirs. I'm home on leave and alotted myself an hour to do this repair. It took me less than ten minutes and the picture looks like new. Thanks so much, and watch out for Sony, I'm sure they will want to come after you for all the money they have lost by people reading this and fixing their own sets.

Thanks so much. Been living with these green ban lines for two years. Had the red bulb replaced ($500) and thought the green blub needed replacing and didn't want to spend another $500 but instead it was just a simple 15 minute fix. Once again thanks.

YOU ROCK, I HAD THE RED LINES FOR OVER 2 YRS AND DREADED THE THOUGHT OF SPENDING THE $$$$ OR REPLACING THE TV. a FEW months ago we had a power surge which resulted in the tv powering up for 3 seconds, then the screen would fade to blue, then it would power down into standby mode, light blinked 8 times etc. Found your blog, 10min's and 1 small adjustment to the blue knob and PRESTO!! GOOD AS NEW!
YOU ROCK MAN!

I have a KP-51WS510, and the
problem is the left side of the screen has green and red lines, offset. The right side of the screen is fine. Can I adjust the left side of the screen idenpendently from the right, or is there another fix?
Thanks,

Anonymous said...

This fix was wonderful for my problem : blue trace lines, after 10 mins blue flash and back to normal screen, a few more times blue flash again and back to normal screen. Finally a blue flash and goes to stand by mode.

It took 10 mins to turn the blue screw by 1/8 turn and problem is fixed.

Called sony and they gave me BS of out of warranty. Asked me to call the authorized technicians. Tech said it would cost between 300 to 1000 $$$.

Looking at this post, there are so many people with the same problem. So sony should be aware of these issues. We pay almost 50% more money to buy sony TVs and this is what we get !!!

How about a class action law suit against sony?

The fix looks great but I can't get to it. I have the red line problem on my Sony KP-46WT510 and I can't see how that front cover comes off. It is probably simple but I just don't see those little screws. Thanks for any help as so far just the run around from Sony by phone.

OMG, thank you so much!!! I spent the earlier part of this evening looking for a new TV. My wife gave me 1.5 days to buy one for the new season premiers. The TV shut down during the Dallas game last night. I told my wife it was due to Dallas. Ha Ha. Anyway it was a green view with green lines and after about 15 seconds it would turn off. After reading your fix, I turned the green screw 1/8 CCW and on power up, I had a great picture. Again, THANK YOU!!!!

Hey - when i first read you blog i was really excited because the thought of having to spend the big bucks on a new tv was scary, however after attempting your fix nothing has changed. i have a blue line part way across the top of my screen and a green line all the way across the top. there's a horizontal area in the middle of the screen where all is clear (maybe 20%), the further you move up or down the more the green color shifts. to the point where it's off by a couple inches at the top / bottom of the screens.
any thoughts?
any help would be greatly appreciated.
it's a sony kp48v75

Unfortunately I do not have specific experience with the KP-57WV600. However, if you do a couple of Google searches for kp-57wv600 service manual, you will find some sites that sell them for $5-$15. The service manual would most definitely describe how to perform what you need to do.

Thank you for the info! I had the blue and red out of focus a couple of days ago. I tried this process and the blue got straightened out. But the red is still about 2" off to the right. I tried adjusting all three and no dice. Do you know of a way to adjust the red gun itself?

Ken,

You are certainly the man! I purchased a used Sony KP-51WS500 for a few hundred dollars and thought I got a steal until later the same day I noticed the red lines and while watching a movie the screen would sometimes have a red tint fading in and out. I thought it would be an expensive repair until I saw your advice. I am mechanically challenged but the pictures and instructions were very easy to follow and 10 minutes later I had a beautiful picture. Thank you again for your help!

Hello Ken, I have a kp53s70 I have horizonal lines but are sharp and black, maybe and inch or so thick and about 2 -3 of them. Do you think this fix will help??
THey come on ond off but usually stay and when they appear the picture quality also goes.

Ken,
You are the man! I followed your instructions step-by-step and it worked. I've had those annoying red lines for about a year. I always thought it came from inteference from one of the numerous boxes I have hooked to the television.

That sounds like it could be an issue with the red lamp perhaps having cobwebs, spider webs or a little bit dirty. Have you opened it up and taken a look?

This fix would not apply to you though.

TO THE GOD OF TV REPAIR - Ken Hanscom
You are GOD. My Sony HD TV had the red lines for at least two years. It only took us 10 minutes with your detailed instructions to fix our problem. BY THE WAY We called sony repair hot line and the tech said Sony has NEVER heard of this problem before. HA HA I guess they never heard of you either. We can't thank you enough. Tell me were to send a donation for all your help. We were just about to spend money for no reason I'd rather spend it on someone that deserves it.

By the way we have a question on maintenance.
What's the best way to clean the components inside the tv? And when is a good time to replace the bulb? Where would we buy the bulb from?

THANK YOU FOR YOUR TIME AND GREAT ADVISE.

Anonymous said...

Thank you! I cannot say thank you enough. I was having the same problem where we would switch on the TV (KP-57Vw700), green lines across would appear across the screen for about 5 secs and then the TV would power off or rather blinking on Standby. We had someone come and take a look and the TV and he wanted to replace one of the bulbs for a $1000 Bill (650 for the lamp, 250 Labor) - Needless to say how much you have helped people...Thanks! The only problem now is that it takes few visible seconds (abt 30) for the picture to come up...I think something we can live with....

Thanks!

Thanks for this website. Took care of my blue lines on my KP57WV600 in about 10 minutes. Like others, I was ready to buy a new set. To remove the cover on the KP57WV600, remove the 5 screws behind each of the speakers. Then pull out the bottom center of the grey panel. It is held in by 4 snap type pins. The cover hinges at the top. Rotate up and be careful not to pull out the wires connected to the front panel. Then proceed as directed here.

My Sony KP-57WV700 had the blue lines and backround that made a major irritant while watching it. I went out to the internet looking for a solution, but found nothing at the time. After calling several repair shops, I was quoted from $250 to $450 to fix the problem. I went back to the internet looking to buy a repair manual and see if my problem and possible fix would be in there. Thats when I found your blog. I can't thank you enough for the easy fix! I join the rest of the comment writers in thanking you for the stress relief when watching a quality picture again, and for the money saved just in time for the holidays.

and i cant turn the red anymore without the actual color of the picture looking wierd!

wat to do?

Anonymous said...

The CRT's (picture tubes) are bad in these sets, Sony has a technical buletin out on it. Adjusting the G2 (screen) controls will only prolong the inevitible, necessary replacement of the CRT's, Sorry for the news, this is a costly procedure and now new CRT's are not available for all models and will have to be replaced with a remanufactured unit. Best bet to adjust G2 down untill need replacement of whole TV. I have worked on quite a few of these, but the G2 will work for a while.

Ken Hanscom said...

Anonymous, let me resepctfully disagree with you. "Prolonging" the inevitable is always the case with any consumer product -- it will eventually go bad. However, by adjusting the G2 settings on my television -- I have been prolonging the "inevitable" for 3 years, or basically 50% of the life of my television. To me this sounds like a repair-persons ploy to keep a steady stream of income for what appears to be a standard maintenance procedure for a Sony Projection TV set.

For those with KP-xxWVxxx TV series you need to remove 5 side screws, just behind the faceplate covering the speakers, next - pull out the 4 round-shaped clips on the botton of the faceplate and last - push-in the top part of the faceplate & pull down at the same time to dislodge the 4 large flat-shaped clips on top. As Ken noted that you could damage your TV while doing adjustment w/ TV ON, I would recommend doing the adjustment while the TV is OFF since these knobs are sticky w/ white paint marks/glue/dirt so doing fine adjustments could be difficult (if not it would shut your TV off & keep on stanby mode & possibly damage your voltage regulators & you would not able to power up again/auto shut down periodically!). Hope it helps!

Ken Hanscom said...

Paul, I'd agree that some more fine tuning is needed to get the blue horizontal lines out.

Samir Shah said...

does anyone have any recommendations for me? I tried turning the red voltage meter a little to the left and also all the way off and there is a still a broad line red hue and the picture is out of focus with a red glare.

Ken,
Great tips! You are saving money and headaches as well as (oh no! :) "empowering" the people! My question: Is it safe to assume that this process will be similar with other brands of RPTVs (Samsung, for instance)? And (I know it's asking a lot! :) do you have any links for fixes for other brands of TVS? Thanks!

Ken Hanscom said...

That's an interesting thought! Honestly, I am not sure whether this fix would work for other manufactures like Philips, JVC, Pioneer, Toshiba, Magnavox, etc. You would think the design and the components would be fairly similar, but your guess is as good as mine!

Not aware of any other links, as I have not researched any other brands. However, if you crack yours open, it works, and you take pictures, I would be happy to do a post on it!

This fix actually works, UNLESS you have the problem that I have with my set. It is known as the flicker symptom and can only be fixed completely by changing two chips resistors on the A-board. It only occurs in less than 1% of the Sony's but it is an expensive problem if you don't recognize it early enough. I have gone through 3 CRT tubes in the past several years (at $500 a pop) before I found this problem at www.freelists.org/archives/techassist/11-2004/msg01107.html

Check it out before you have to replace CRT's.

great post helped me fix my Sony KP57wv600 but i do recommend at least with my set, to buy the service manual, because the picture up top with the ray guns is actually backwards i needed to adjust the Blue gun causing the arching lines across the screen, and Blue is on the left not the right as shown, mine were even labeled, so for anyone useing this to fix there set, double check and see it they are labeled or look into the service manuals so u dont happen to turn the wrong knob, but other than that worked great, blue lines are gone, so lets hope this fixes my issue

Sobrtec said...

Help! Sony KP-65WS500. I had been noticing blue, arching lines on dark screen for a few months, but thought it was my dvd player. Then, after connecting dvi to hdmi cable from my tv to my laptop, tv screen went blue (more prominent arching lines) then tv shut off giving 8 blinks. Coincidence? Could connecting it to my pc have caused some problem? I don't know a thing about tvs, so any help would be great. Thanks.

digital said...

I love this guy, IT WORKED, IT WORKED. After about a year and a half of wathcing tv with those annoying blue lines and blue screen when there was a dark scene i was finnally able to watch tv comfortable again. No need for a new $2000 tv now. Thanx a bunch!!!

hey ken thanks for the help but i had only one problem when i was about to do it. i have 3 colors the red, green and blue, it looked like a 3D movie when i adjust them do i leave the tv on? and what do you mean when the colors arch?
thanks alot if u can help

Anonymous said...

Ken, Great description and great photos of the KP-51HW40. Had the blue arching lines in the TV for about a year. Technician stated that new tubes were needed. Anyway, the entire process took 15 minutes and the blue lines are now gone. Thanks so much for your time in putting together the instructions.

Anonymous said...

Awesome/helpful post! My son and I successfully (and quickly) solved a green-lines problem by following the instructions - worked like a charm!

Anonymous said...

Excellent post Ken. Thanks for the help. Solved the blue line and then the red line problems.

Anonymous said...

Ken~YOU ROCK! Our TV has been sitting in the spare room for 3 years. I finally decided I was either going to pitch it or see if there was any help offered on this problem on-line. I searched and searched the Sony site only said to call a repair man or order new parts. After looking at your pictures and reading your instructions. I had my picture back (it was completly blue before) in a matter of minutes. I actually had to call people up to tell them I fixed it I was so happy. I can't thank you enough, but thank you anyways~Mikel

Anonymous said...

Just another satisified customer wanting to say Thanks. We've had green lines for over 2 YEARS now. Started shortly after we moved, so I don't know if something got jarred when the TV was moved. Anyways, I had a hard time finding someone to even come look at it, so we just put up with the lines until I found this solution. My wife was skeptical, but it really did only take 10-15 minutes to do. Thanks again!

MhaPhew said...

Thank you so much for the "how-to"
however it didnt work for my TV (also i have a mitsubishi and the controls look almost exactly the same)

But it didnt work because i think my green tube is dead, can you advise how to fix?

Loredo1117 said...

Ken, tried to download the manual as suggested, get the "forbidden" message...... is there another place we can download it? Our Sony KP-51HW40 has a blue screen, light blinks 5 times, then goes totally black and shuts off. We're going to try your fix but would like the manual.

Anonymous said...

Wow! You are a life saver. It worked like a charm. The blue lines that we've been dealing with for over a year now are gone!We didn't want to fix them because we thought it would cost a lot of money. It was so easy even a woman can do it. That's right, I'm a woman and I did it all by myself. Thank you so much! Sony should be ashamed of themselves for charging an arm and a leg for this.

Anonymous said...

DUUUDE, Thank you so much for posting this. Everything I read up to this point was telling me that I needed to replace the CRT...if I could find one. Awesome!

Paul Bx NY said...

Youre The Best Dude !!! Took The Blue Lines Right Out Of My KP-65XBR10W
and Gave Me A Beautiful Picture Again !! God Bless You Always !! Paul

Anonymous said...

THANK YOU THANK YOU THANK YOU!!!! KDP-51WS655 here and your fix worked perfectly.

Too bad companies like Sony can't figure out to help their customers the way that you did.

I spent an hour searching their support site and on the phone with a technician.

And a Google search and 15 minutes later I had my TV back just in time for Super Bowl!!

Loredo1117 said...

Never did get the service manual, but we tried what you suggested and WOO HOOOO, it worked! In fact, the color is better than ever. Got rid of all the lines. Had to tweak it a couple of times, but was worth the effort to get the front panel off. Thank you thank you thank you.

Anonymous said...

Ken- I have a convergence problem with the Sony kf-60dx100 rear-projection LCD model in which a fainter, soft 'ghost' image is visible about 1/4 inch to the left of everything (text is the worst, but it's visible on everything on the screen). Do you think this type of adjustment could help? Any other ideas? Thanks much.

Scott said...

Thank you! Red lines for almost a year are gone.

K.J. said...

YES!!! It did work on my KP-57wv600. My model required me to removee the 5 screws on the rear facing side panels (LH and RH lower facing aft) then with moderate force grab the lowest edge of the gray front face panel and pull out towards your self. Gently supporting the weight of the panel since there are slotted alignment pins at the top of this panel. The rest of the proceedure is spot on. Oh ya, try turning counter-clockwise on your initial adjustments and like you say Ken, slowly turn them. I owe you one pal...Thanks!!!

Kevin

Candy Jo said...

May I say that you are my HERO??? I have a 2003 57 inch projection TV that has had the arch shaped green lines that were getting larger & larger. I am "just a girl", followed your steps and walla green lines gonzo! I like my TV again...you're the best!!! The speaker covers were a bit of a scare to remove -- I thought I was going to break something so if anyone is hesitating to try this, you can feel confident that it will work. My model KP-57/65WV600. I didn't see it on the list. YOU ARE THE BOMB!!!

emmanuel said...

Ken,

I've got red lines on my KP-51WS510. I need to get this fixed before the the Big Show and I need to do it myself cuz I got no cash, but I can't get in from the front (no speaker screws on this model).

I'm obviously no tekkie but can I get in from the back and do the directions apply as well.

Many thx bruddah!!

KEN if you were here id KISS YA..My TV works great...
I've been dealing with the red and green lines for like a year now...and then tonight the screen went solid red and the tv would just shut off. When i turned it back on it was solid red for 20-30 secs then it shut off again. So the first thing i did was check my savings account..then for the hell of it i googled the problems and this link came up...I followed your instructions turned the TV on and started adjusting the red and WALA...So i proceded to adjust the green to get rid of the lines and now the TV's perfect
Thanks a bunch you just saved me 2-3K for a replacment...

remicke said...

I can't believe how simple this fix was!! My TV had gone from red lines to total red out. Now the picture is perfect. Thank you! Thank you! Thank you!

PP said...

Wow! This method also works for my TV. I have a Sony KP-57WS500 projection TV.
The screen slowly becomes blue after I turn on the TV and finally completely blue. Then I can not see anything.

But after adjusting as Ken mentioned here, the TV is working well.

Thanks a lot, Ken!

Set (kp65wv600) was given to us by a wonderful neighbor that said his repair tech wanted $1K for repairs and parts. It was only a few years old and the warrantee had just run out.

We found a request for help on the net that led us here ... and now we are so grateful for the tip. A few screws removed on the front, a tweak on each of the 6 knobs for maximum clarity and individual color drive ... couldn't believe how terrific big-screen TV could really be.

Thank you so much!

Dave said...

Hi Ken,
no luck. Still have double vision, blury picture. Green, red and blue verticle lines. Any other suggestions?
Dave

Ken Hanscom said...

Dave -- double vision would be a slightly different symptom than the arched horizontal lines that I was experiencing that led to this post. Unfortunately, I do not have experience with what you are seeing. Perhaps someone reading this post can help?

John said...

Ken - 2+ years of red lines, gone in 15 mins. Your blog has helped so many people - thanks a million. I googled this problem several months ago and unfortunately didn't come across your site. Found it today thankfully, problem fixed.

Do you know what the top 3 dials do? Also the link to the service manual didn't work, could you repost a link to the file on your blog?

Ken Hanscom said...

John -- sorry, I do not know what the top three item do. Unfortunately I cannot post the service manual -- it's a copyrighted item for which Blogger would most likely TOS me for them. However, if you do a google search for it -- you may come across it.

Anonymous said...

Ken,

Thank you!

As usual ... your tips worked to perfection - and saved my Super Bowl! But I have a couple of follow-up questions:

1. Is the dial "tweaking" an overcompensation for a failing element in the TV?

2. If so ... how long will this fix last?

Thanks again!

Ken Hanscom said...

1. Not likely, I first had to do this to my 51" 3 years ago.

2. I performed it twice -- interestingly only on RED, Green and Blue have been fine. I am starting to get very faint red lines again -- so it looks like every 12+ months is about right for the adjustment.

Can't thank you enough!

Hello, I have a KF-60XBR800, and I am having some problems finding my convergence. I tried opening the bakc of my TV but I still could not find it. I can't open my TV from the front like you said, I have no plastic covers. If you could help that would be great, thanks.

granny said...

Ken,
Thanks so much for the post. My tv had arched blue lines on it.
I'm 55 years young and it took me 30 minutes to open the tv and make the corrections. I didn't have to use a screwdriver on the controls, they were easy to turn with fingers.
Now my picture is line free and colors seem to be better even in vivid mode.

Frank said...

Ken,

Thanks for the info. You just saved me $$$ and a big headache of having to deal with this. Followed the instructions step by step and all is well. My kids are even amazed that I could actually fix something. I couldn't believe how simple this was. My picture looks better now than it has in quite some time. Thanks again.

Anonymous said...

Ken, I have a 4 Year old 46WT510. This Info was nice but did not help me one bit. First the steps for taking the front off were all wrong on my set. Second My wavy blue lines are still there. It looks like a blue shadow of any words on the screen. Any other ideas on what is wrong with it?

Auction Tips Guy said...

Ken,

You are amazing! I have a Sony KP-57WV700 57 inch TV and the screen would be blue when I turned it on and then go black. The standby light was blinking continuously. I followed your directions and my TV is now working perfect. On my model though, the cover was a bit tricky. I had to first pull at the bottom of the cover to unhook the clips that are behind (and can't be seen). I can't thank you enough. I'm definitely clicking on something for you;-)

Thanks!

Anonymous said...

Dude you rule.......I'm making a shrine to you on top of the tv. Just as a reminder to the tv how close to the dumps it got.You saved it's life. You ,Sir, are a "sony rear projection tv repairmen god". You brought my tv back from the dead. thanks

Auction Tips Guy said...

Ken,

Just a quick followup question. I noticed my set had a quick flicker...almost as if it was going to power off but then returned to normal. It is a very fast, slit second thing that seems almost like the TV is shocked or something. This has happened twice in a few hours since doing the fix. I'm wondering if it's possible that I turned one of the dials too far....as I did turn all 3 dials in order to get the clearest picture I could. Any thoughts on this would be greatly appreciated.

Thanks again!

Kyle said...

Today I went to the best place in san antonio texas for HDTV's. They told me they had never heard of green and blue lines on the screen. When I got home, I opened up the front of the tv. 1/8 turn to the left and i was done. I was going to be charged $120 just for the idiot service man to get to my house.

Anonymous said...

This was very helpful. Bought the tv used (kp57wv600) and immediately noticed blue horizontal lines. Must have been knocked out of adjustment being moved in a cargo van and down stairs. 1/16 turn CC and the pics is fantastic! On my model, it is 5 screws on each side (back) by the speakers. It takes a good tug (best to start from bottom)to get the front panel off. I used this site and some posts from Fixya to do the job.

rowdy said...

thnx ken I was given this tv(57wv600)blue screen 7 blinks ,,, grabbed a philips and voila.. but now I have a puzzling problem?... on initial blue adjustment the only "pic mode" that would work was "standard"..2nd adjustment only "vivid"... then adjusted red and could only get "movie" and "vivid" noticed green lines so adjusted and have perfect pic and color but only have "pro" mode and when I try to change to another mode the screen turns blue then black with sound and back to blinking lights... I must turn tv off and back on to get picture back??? . this was the same result after every adjustment??... any help with this one would be great and thnx again ken!!

Anonymous said...

Wow. I can't believe that this is all it takes. I bought a 65 inch KP65WV600 about 5 years ago. I started getting green lines about a year ago and didn't think much of it until the other day it finally shut the screen down. I talked to many service men about my green lines and the T.V. shutting off after turning all green. Every single one said even before they came out that it needed a new green picture tube. The problem is that they don't make them for my T.V. anymore. It was a sad day to say the least. After reading this I took off the front cover and adjusted the green knob a little at a time. Nothing happened at first even after turning the T.V. on and off. So I fiddled with the red and blue a little too and just like that I had my picture back. My T.V. was actually shutting the screen down to black after going bright green instantly and now it works. I think I still have to adjust the color a little but man am I glad that I actually have a picture again. I hope its a permanent fix. I saved $$$ to say the least for not having to either rebuild my tube or buy a new one. Thank you so much!

Phil said...

Hi Ken,

Thank you for your help. The fix worked great. I am still having another problem, though...my green will go out of focus, that is, any white lines will get a greenish tint and then the set will auto adjust and the picture will be crystal clear again. It has the effect of blurring the picture until it auto focuses again. Convergence on green off?

Thanks in advance,
Phil

dude......You Rock! Thanks so much. Like everyone else, I was dreading what was going to happen. I have a Sony KP 65WV700...owned is since 02. It has been amazing and I think because of you I will have it for another 6 yrs...thanks again

Thank You,

It only took 10 minutes to fix the red lines that I had in my screen for the last month. I didn't even have to turn the red screw. When I touched the screw driver to the screw there was a electronic snap noise that happened then the red lines disappeared. I had to speakers behind my TV. Maybe the magnets in the speakers did something to it? Thank you again, your site was such a great help.

Ken

Omar said...

Hey Ken,

My TV is also off on the red lines. Did your TV have a 3D'ish look to it? It appears mostly on the bottom and the top of my TV screen.

Ken Hanscom said...

Omar, no 3-D or real focus issues for my television set. It was purely red lines in my case. Perhaps start with the fixing the red lines and see how that improves your picture.

Anonymous said...

Let me add my homage to the above. I've been living with blue lines for a long time on my KP-51WS500, and this quick procedure fixed it. Thanks so much for posting! Also, thanks for everyone that posted supporting comments; I needed those to summon the courage to crack the case open. :)

Anonymous said...

Thank you for sharing your information! We had the blue lines for 2 years and a year ago the whole screen would turn blue. Sometimes turning it off and on would fix the picture. We finally found if we didn't turn off our tv the picture would stay ok. We have not turned off our tv for 10 months!!! I read your blog and decided to give it a try while my husband was at work. I have no experience in fixing anything but I do know how to use a screw driver. The picture was fixed in 10 minutes! Looks great! Can't wait to surprise him when he gets home and it will be nice to finally turn off the tv at night! Not only did you save us repair $ you saved on my electric bill also! Haha!

Thanks again,
