Question about Vizio VP322 32 in. Plasma TV
Hello; I am John at J D Electronics in Poland, Maine. I have now repaired 4 of this same model in my shop. The set may be dead always or work intermittently. There are 2 versions of this piece of junk, but I have only seen this one. They all have 2 capacitors that fail on the power supply board just above that red chopper transformer. The are labeled C233 and C234. These are 3300 ufd at 10 volts and 105 C temp rating. You can buy these for about $1 each from Digi-Key Electronics. Make sure they have the Panasonic brand. There are some cautions worth mentioning. Make sure the set has been unplugged for a day or more before starting the disassembling. It is VERY important to keep the set face down on a soft surface when doing ANY work on the set. This crappy designed set has a glass faceplate that will fall down if you don't have it face down when all the back screws are removed and it is very hard to put it back into position if it falls. The bottom plastic speaker strip has a million screws to remove both from the bottom edge and the back. then take out all the screws for the metal back and unplug the speakers. The connector wires to the speakers will not just pull off without you pressing on a side release pin for each of the 4 wire- Stupid design again!. Good Luck! John

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

SOURCE: Hey guys, got 32
If you feel good about it, take off the back and examine the capacitors on your power supply. It should be located near the center of your set. In the event you can't find it, locate where you plug in your power cord and follow the path of wires until you find the circuit board where they plug in.
That's your power supply. The capacitors are the cylindrical objects on the board. They range in size and can be very small, to quite large. Look at the tops of them. They should be flat. If you see any that are raised in the center, those capacitors are no good.
That cycle you are describing is reminiscent of other sets having a similar problem. In those cases, it is the capacitors on the power supply that cause the issue. You can replace them with higher rated capacitors, if you prefer, or you may replace the power supply.
Hope that helps.
