50" Plasma Vizio flickers from blank screen to pixelated, no sound. There was no pop or anything prior to this, it just went from working to this, tried all the reboot options and nothing changes.

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

My kids were watching our 50 in plasma tv when there was a loud popping noise and the image went out but there is still sound, I turned the cable and tv set off to see if it would help but it didn't work...


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

I have a 50 inch plasma vizio tv. I was watching it then i heard a pop the screen went black and i still had sounds yesterday but today no sound, I called vizio tech support they told me it was the gas...


when you here a loud pop its usually the sustainer boards. Have you checked the fuses on the sustainer boards first to see if they are still good. There is a IC chip under the heatsink and when it gets extremely hot it gives. Also check you power supply board to make sure you don't see any swollen capacitors, leaky or bulged out from the top. Let me know if that helps at all.

I have a Vizio 50 Plasma TV. Sound works but display is "noise".


It'll be the X or Y boards or maybe the power board, without checking the VA and VS voltages I can't tell.

Vizio p50hdtv10a left third of screen is black on all inputs. I still see pixel flicker at start up so I don't think the display is damaged. Out of warranty and of course Vizio is no help.


Check the connections on your Y sustainer board (the board on the left that go vertically if facing back of unit). Also check the driver boards toward the bottom of the TV. Your connection may not be in all the way and that will cause the missing display.

Vizio 42 Plasma Pop


My 42 Inch Vizio experienced the pop of death out-of warranty. I bought mine at Sears and they sent a technician over within a day or so. It turned out to be in the power supply and they shipped a board right out. Total including parts and labor was $280. Although no expensive TV should die after less than 2-years, Sears seems to be able to deal with repair in the home without drama.
