    Same exact problem here!  We were just watching it then it blanked out!  No pic No sound.  And yes, it seems locked up once it's powered up.  I've gotta unplug it to turn it off.  Very Frustrated at the moment!  Any additional tips in fixing it?

We have the same problem and purchased a power supply to see if it would fix the problem. It didn't. We are now in the process of buying the main logic board and we will let you know if this fixes the problem. It seems like it is in sleep mode but doing the steps to get the tv out of sleep mode does not work.

Vizio e322ar won't turn on


My Vizio E322AR White Vizio Light comes on when plugged in, then slowly fades to "Off". I unplugged and replugged - same. I held down the power botton on the side, and plugged in... same. Vizio light comes on (White) and over 5 seconds or so... fades out to nothing.
Remote doesn't do anything, buttons on the side don't do anything.
Going to pull the back off and look for bad Capacitors, and test fuzes for continuity. Wish me luck ... will report back later with results.

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

My Vizio VX32L LCD TV will power on but no picture or sound


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: 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.

No picture but sound


do any lights come on with the TV?, like white vizio or orange vizio light. sounds like a problem with the power board. some vizio parts have lifetime warranties so contact vizio support and report your problem. if it is covered the service call is free. there is a green led light on the power board that should come on, if it is not on, you may have a bad power board. to see this light on the power board, turn off the lights in the room and view the tv from the back cover, power board is 3/4 way toward top in the middle of the tv
