I have a vizio vw42lfhdtv10a that has picture, but after a few minutes from power on, the colors go WAY out of whack and then eventually goes near black, and then returns to near normal. This cycle seems to be stuck in a loop
After reading a few threads here, I thought it might be the backlight inverter and replaced it, to no avail.
I have sound, controls and everything else works fine. I don't think the power supply board is the problem, so I guess that only leaves the mainboard, right?
Any helpful info would be appreciated. I just want to know if replacing the mainboard is the most probable fix before dropping the green
