Question about Vizio VP322 32 in. Plasma TV
You will have to check your Vs, Va and 5 volts coming off the power supply to make sure they are exact. The Vs and Va voltages will be posted on a sticker on the top of the display panel on the back side. You are treading into an area that does require technical ability to rectify or you will waste money on un-necessary parts. In most cases when caps are going bad they fatigue other semiconductors, usually on the Y sustain panel. Plasma power supplies are totally different from LCD when it comes to just replacing bulged caps. I recommend a qualified technician look at this particular problem for you.

I have fixed two of these models in the last week both with no power:1st one I replaced 5 capacitors which fixed it.2nd one I fixed I replaced 2 shorted out capacitors,you could hear it turn on then off.Before it shut down the vs voltage was 208 volts where it's supposed to be 195 volts,adjusted down to 195 and that fixed it.Hope this helps

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem.
My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of
course) and found four bulged capacitors.
Many electronics companies were sold capacitors that failed in 2-5 years
instead of 10-20. The capacitors fail
prematurely due to a lack of preservatives. Unfortunately, they were installed in all
sorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional
2. Open your TV and find PSB. Check
for faulty caps. If you find some (bulged
or leaking) bad caps replace the entire board.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourself
it will save you hundreds.
I have a tip/tutorial
on this site that may also help. It
gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's
called: Fixing the Philips Turns/shuts off on its own problem.
Hope this helps and Good luck.
