Re: Vizio XVT473SV Troubleshooting
Mine was fixed by replacing the power supply board. Took 2 tries, the first one I got was bad. It was from River Valley Electronics and they never returned phone calls or email regarding the bad board. I wouldn't use them as a source. Got the second from an individual seller on Ebay.

Re: Vizio XVT473SV Troubleshooting
Was this problem ever resolved? I have no backlight, see virtually identical voltages as posted above and also the blue LED on the inverter board flashes just one time every time I turn the TV on (white logo state).
Sound is ok and I can see video on screen when I shine a light on it.Leave a comment:
