    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.

The LCD screen is dark with no sound or picture when turned on.


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.

We have a Vizio model # GV47LFHDTV10A. When we went to bed last night the tv was working fine. We tried to turn it on this morning and nothing. There is some power. The Vizio logo lights up and so does the...


For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.
