My Vizio E422VL was working fine. I moved it to another room and it continued to work fine. A few hours later the TV will not power up, no lighted Vizio logo on the front. The TV does have power becau


You may have a power board issue. It may have simply blown the internal fuse also. Couldn't hurt to check it? Moving it may have possibly jostled it? Especially if you get no 'Power light blibs' on and offs when you plug it in. Usually these flat panels have some power light diagnostics. Like 3 on/offs then full off says power supply.

You will need to get a diagnosis done on the set. It could be a power supply issue or a main board issue. Your problem is between one of those two boards.

Vizio TV 2006 vx32Lhdtv doesnt work.


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.

32" VIZIO PROBLEMS


The main board is bad. I have seen a lot of TV has the same problem like you have. Replace main board will fix it. If you bought these TV from Costco and less than 2 years then they all still under warranty.

No Power to a Vizio VX32L


My best guess is to check for blown fuses or the power board when bad inside the TV.
If that doesn't work, looks like you'll have to pay a repair shop to find out what's really going on.
Sorry I can't help you further.

Vizio 50 inch plasma -- remote not working


You can also try to take out the batteries and push all of the buttons with the batteries out of the remote. Then put the batteries back in and push the power button on the remote. If this doesnt work press the two TV buttons at the same time and the remote should be fine.
