Hello,
turn on the set, grab a bright flash light and dim the lights in the room. Shine the flash light on the screen, if you see a faint picture on the screen, you are dealing with a backlight problem. There are several things that can cause this. One, a bad backlight inverter, two, faulty 24vdc power supply, three, bad main board, or a bad faulty backlamp.

What cable is being used? Often times there is a few things that could effect the picture and causing flicker. If you are using an HDMI cable, or the hdmi plug on the box or tv, you could have that problem. Because the picture is digital, you don't get the snow and lines we were used to. Because the cables are so stuff, often over time they can stress and pull on the plug and cable. Try a new cable, if that does not work, try another hdmi input on the tv. If that fails then try a new cable, like a component cable or RCA. If none of these work and you still have this issue with the box then most likely it is the tv or the box. Swap out a new source, and start this process all over again. If you get the same result then it is the tv. If it works with the same cables, then it is your box. Att will send you a new box if that is the case. If it is the tv, call Vizio. Warranty or not call them. If you are sure you are out of warranty, play dumb, be vague but nice. Often you can get someone out there still at no cost.

I would like to know if you would describe the picture or screen as a dark swirling cloud like one?

Do you have backlight? If you do, you have a bad main logic board. Very common with vizio and are hard to find. They are usually out of stock everywhere.

I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

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.

Hi,
I work as a contract technician for Vizio, and I can tell you from experience that replacing motherboard is one of the only solutions to this problem. The other solution if under warranty is to replace it. If you experience red, blue, or green pixels where dark shades (like nose, eyes, clothes, etc), call Vizio and accept nothing less than a full replacement! I have had situations where I replaced motherboard and within 2-3 hours the pixels return. Hope this helps.
