Hi, my vizio 50" plasma just made a loud pop sound and then the picture disappeared. the set powers up but no picture and no sound. How can this be fixed. how much will it cost to call vizio to come fix it. Any ideas, comments.? thanks
Wow. This is more comon than I thought. My 50" Vizio plasma just went out as will after a loud pop noise. Power button is still lit. Sound continue to come through but no picture. I will dig into it and see if I can find a appropriate solution.

Re: VIZIO 50" PLASMA
The power supply in these sets have had bad electrolytic capacitors which short and actually blow their top because of increased pressure. Only part of the switching power supply is now running so you may see a power light but nothing else. I am not sure what Vizio would charge to replace the cap or supply. If this is the case, we would charge for 1 hour labor ($120.00) and for the capacitor ($3-4.00)unless the manufacturer recommends replacement of the power supply.
Hope this helps you.

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.
TV was on with no picture problem. Left the room and when I returned the picture was very dim. Turned system off and turned back on. Picture didn't change, but heard a loud pop from the back of the TV.
This may have been the sound of electrolytic capacitors exploding. I would not suggest plugging the set back in until you can have it checked by a qualified TV technician. If you are skilled in Electronics and would like to work on this yourself, you will need:
The schematic diagram, a multimeter, a signal generator, an oscilloscope, and an isolation transformer.
