Wii Sensor Bar Tear Down and Repair Guide

With my recent purchase of a "broken" Nintendo Wii from eBay, I have taken the opportunity to disassemble the various components. As part of that effort, I am posting about each experience, to help you out in the case you need information on how to repair your Wii.


Nintendo Wii Sensor Bar Tear Down and Repair Guide with Picutres
In this post, I will be be covering the tear down of the Nintendo Wii Sensor Bar. The Sensor Bar itself, is an infrared device (IR) that detects and determines the movements you make with your Nintendo Wii Remote. It is a critical component of the Nintendo Wii and required for most games.



This post is one of several on how to fix problems with your Nintendo Wii. To see the entire list, click here for the Nintendo Wii Repair Guide.


As part of this guide, you will see how to take apart, disassemble, and repair a Nintendo Wii Sensor Bar. Some common reasons that you may need to open your Wii Sensor Bar include:

  1. Clean our dust or debris that has built up over time on the sensors or the components in the sensor bar.
  2. The Sensor Bar has been dropped or fallen and the covers over the senor components have popped out and need to be reinserted.
  3. The senor covers are cracked or need to be replaced.
  4. The senor strips and cables need to be replaced.

The only requirement that you need to complete this tutorial is a Tri-Wing screwdriver. Once you have your triwing (3-prong screwdriver), you are ready to go.

1. Remove the three small tri-wing screws from the back of the Nintendo Wii Sensor bar, as you can see in the picture below.

2. Now with the first three screws removed, there are two additional tri-wing screws on the Nintendo Wii Sensor Bar that are hidden. These are underneath the two adhesive, rubber tabs that are on each side of the Wii Sensor Bar. As you can see from the picture below, you need to carefully lift up both the adhesive and the rubber on the outer most edges to expose the screw. Once they are exposed, removed both screws for a total of five. All five screws are the same length, so there is no need to keep track of which screws can from which holes.

3. Lift up to remove the cover from the Nintendo Wii Sensor Bar to expose the internal areas. The sides are lightly clipped so it is best to lift gently from the center creating a little bend for the tabs to disconnect.

4. With the internals of the Wii Sensor Bar exposed, you can remove the two covers (one on the left side, the other on the right side from the sensor bar. To do this, lift from the outer most side upwards and the tab that is connect to the center will release, freeing the cover. The sensor bar strip with the sensor will need to move a little as you create the angle to correctly release the covers.

5. Now remove the center black plastic piece from the sensor bar. This is a simple lifting of the piece that is held in place by the two round pieces in the center that it sets on. Simply lift it straight up to remove from the sensor bar.

6. Lastly, lift out the senor bar strip and the cable from the sensor bar to complete the tear down of the Nintendo Wii Sensor Bar. Remember the the cable has a knot in it (odd) to hold the cable correctly in place and that the senor bar cable goes underneath the sensor bar strip when reassembling.

Now you can perform any of the activities you desire. To reassemble, simply follow the above instructions in reverse order to complete the job.

cat chewed the cable... have cut out the damaged section but when I reconnect the 2 conductors, it still does not detect the motion from the Wii controllers. Any thoughts.. looks to me like the red conductor might be the issue.

you can light 2 candles, and place them about the length of the sensor bar apart and it will work like a sensor bar.
