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.

My Viizio plasma has soundut no picture.


Hello,

Problem is in either power supply or the Y-Sustain board.
but the Y sustain board is mostly likely to be the cause.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Good luck......

Vizio closed captions are with red background! Dish TV or Vizio problem?? Also red pixel lines/flashes!


It is a TV problem and could be the sustain boards or the mainboard.

Most likely it is the Y sustain board but it is recomended to replace Y and Z sustain boards if one is damaged.

Plasma does stay powered on


Your sustainer board is probably bad. You need to get the Y & Z sustainer boards replace then it should be okay.

I have a 42 inch vizio plasma t.v. and I have power but no sound or picture, I've unplugged it all night and still doesn't work! It's


For the 42" plasma, you need to change your sustainer boards or your main board to fix the problem. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.

For the L42 HDTV, you need to change the inverter boards or the main board. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.

LG 52 inch plasma screen discoloration


This indicates that one of the intelligence power modules (IPM) is failing on the X sustain board inside your unit. If the picture becomes annoyingly noticeable you will need to have the X sustain board replaced (this component cannot be repaired on the board).
