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.

SOURCE: Vizio VW37L no power
Check for bad capacitors in power supply, check voltages coming out of the power supply, if voltages are good, bad main board.. Vizio's are notorious for bad main boards.

SOURCE: My vizio E370VLE is getting no power at all. The vizio logo under the screen isn't even lit up. I have tried plugging into new outlets and even switch out the power cord with a new one so i know its n
the problem is probably your main power board.. these can be replaced by yourself.. find the model no and then enquire about a replacement board ..I have had similar problem tv repairman wanted $500+ to fix board only cost $134..make sure to disconnect power supply ..undo all the screws around back of case including wall mount and base follow power lead entry into case do not touch any circuitry as some capacitors store power disconnect the little plugs that run from the boardundo the 4 screws and replace with purchased replacement board and re assemble..
