Vizio SV421XVT IR Sensor Help

[jcdeighan]

My Comcast and Vizio remote no longer respond to the tv. I suspect it's the IR Sensor. I have found the part online but see no information on taking the tv apart. Does anyone have a manual or video on how to replace the IR Sensor of this particular tv, or one like it?

Remove the back of the tv and the board should be at the bottom. I believe yours would be in the center, some are on the left or right side. There will be a small connector. This board is small, probably a 1.5 inch by .5 inch

If you get the back of the tv off and are still unsure, pop a few pics and we can assist you better if needed
