Vizio (VO37LHDTVA10) is acting up

[zarfu]

Looking for some help with my VO37LHDTVA10.

I experienced the 'yellow light' issue with this TV where the TV would not power on. After reading around this forum (thank you!) and the web, I checked the power board for bulged capacitors and burn out, and did the same for the mainboard. Everything seemed in order. To speed things along, I decided to ordered a replacement power supply board and mainboard to see if I could isolate the issue.

I first replaced the power supply board, which had no effect. So I put the original power supply board back in and then replaced the mainboard. The TV now powers on (progress!)...

However, I'm now stumped by three problems:

1) The screen is off-center, fuzzy, and obviously not as it should be (photo: http://sdrv.ms/14EDHTL)
2) None of the buttons on the side of the TV work except the power button.
3) The remote does nothing.

Any help would be appreciated. NOTE: My technical skill set is limited to replacing parts. I unfortunately lack most troubleshooting equipment mentioned by members here. I suppose I'm looking for high-level guidance to see if replacing parts may fix the issue.

It is quite likely the main board you ordered is for a different LCD panel (a TV can be made with LCD panels from any number of manufacturers) and this is causing problems. You would need to either repair your existing main board or find one which fits your LCD panel, a good parts seller will indicate the LCD panel model e.g. LC370WX1A that the board fits (this is NOT the same as the VO37LHDTVA10 number.) The LCD panel module number is written on the back of the LCD panel's metal case.
