Fixed! Vizio LCD Problem Vertical Line in Pixels (VU42LF)
The Vizio LCD FHDTV television that we have had up in our bedroom had been working great for the last couple of years since we purchased it on a Coscto special about 22 months ago. It is a 42" LCD TV, with 1080p resolution -- model VU42LF.
The reason I used "had" been working great is just a few days ago while watching -- Ashley mentioned, that blue line down the middle is annoying. I thought, what blue line...I do not see anything. But, then changing viewing angles -- I could clearly see it -- a one pixel wide blue line running the entire length of the screen. From top to bottom.
It kind of looked like:
I was not panicing yet, but I first changed the TV channel. The blue line was still there. Then I reset the DVR receiver. The blue line was still there. I then change to a different device using a different connection mechanism -- DVD and Component vs. HDMI. The blue line was still there.
I was beginning to panic.
I turned to the Internet and searched Google and the results were not encouraging. Not encouraging at all. In every case I found, the situation was some sort of damage to the LCD, irreversible and requiring either a costly repair at $400 or replacing the television altoghether.
And of course the warranty on the TV was only for a year -- that would be par for the course.
I was trying to figure out what to do, whether I should look for a new television, see what new LCD screens costs and do DIY repair. While thinking, I fired off an email to Vizio technical support to perhaps get more information.
Resolved to waiting, I was just standing in front of the television looking at the blue line and I did something odd. I just tapped on the line where the one pixel wide blue line was...and it disappeared. It was not really hard, just a tap...tap...tap with my finger and the television was fixed.
Now I am not sure if this works for red, green, black, or white lines in a LCD television, but for some reason it worked for me. If you are having an issue, I would suggest giving it a try. It may not work, but hey -- what do you have to lose?
Good luck!

Unfortunately it didn't work on ours. The warranty was up just a few weeks ago and the blue line showed up today!
that was amazing. i tried tapping the lcd screen itself and didn't work but then tapped the plastic part bordering the lcd screen and after a couple taps (not hard) it started flickering different colors and then disappeared! who knows if it will come back. at least its gone for now. until i can convince my wife for a new tv. lol. thank you! good luck!
I had the same issue appear on my 52" Vizio after a move from AZ to TX. Amazingly, THIS WORKED!!! Thank you very much! Saved me having a huge fight with the moving company.
Had the same issue with a "purple line" running vertical, probably 10-15 pixels inside where the SD/HD aspect cut off is.
Mine had been like that for 2 or 3 months but would always seem to go away after it heated up.
I tapped it and nothing happened, tapped the plastic border, nothing. Then I tapped back where the line was and it was gone.
Who knows if it's a long term fix or not but it's something.
Certainly if your TV is under warranty contact the manufacturer first but this does seem to work if you fix the right spot.
Had the same issue with my 47" Vizio. Came across this first on Google. Worked Great! Thank you.
Incredible, I took your advice and it worked. My Vizio 32" tv had a thin blue horizontal line that just appeared, I thought for sure i'd be looking for a new tv. I first tapped the screen itself no good I then tapped the frame no good, I then gave it a good smack on the back directly behind the line and presto it disappeared. Thanks for the assist..
I tried this on my 37" Vizio 1080p that I purchased 3 DAYS AGO! The blue line is still there and now a horizontal multicolor line is starting to show up. NOT HAPPY!
LOL!
I had red vertical line on my Toshiba Regza Z3030D 47" and this trick worked for me! Thank you so much!
Did this red line come because of stuck pixels? I noticed that it was located right where my desktop backround ends and black area starts.
