Hi Bob, you've going to need to get the back off and get some voltage readings, start with the power supply, go by the legend on the board, let me know what you find, and I'll give you some advice on what to test next

I had the same problem after having a Vizio for 2 and a half years. I
left the room for a minute, i came back and the screen went black.
There was still power to the unit and you could see that the back light
was working, just no picture, no sound, and you couldn't use any of the
buttons. The only way to turn it off was to unplug it. It would then
start up, with the Vizio logo going from orange to white, and then do
the same thing all over, no pic or sound.
HOW I FIXED MINE:Look through the back vents for a white light to make
sure the backlight still works. I ordered a new "main PCB" from
tigerdirectparts.com
(you can also use searspartsdirect.com). This is the circuit board with
all of the inputs on it (hdmi, cable, etc.) I opened it up,
disconnected the old one, put in a new one and now it works fine. I
used
both serial numbers on the board to search for it online. It cost me
$144 to do it, but that's better than $450 for a new TV. My tv is the
vx32l hdtv10a. I hope that helps.
For me the part number was either (depending on the vendor) : 0171 2272
2174 or it was 3632 0212 0150. Check your circuit and see if any of
those numbers match up.
