    Did you replace with high temperature, low ESR (equivalent series resistance) ripple resistance caps ?

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.

    You can also buy the whole power supply from www.interliquidparts.com you have to open up the TV and get the part number of the power supply from the actual part.

    I also have a Vizio VP322 that died. No logo lights, no picture, nothing. I replaced the bad caps and it worked for about 30 min, then the screen went black. When powering on, the logo does turn from orange to white, but then it stops. I changed the 4.0 A 250v fuse on the Ysus board and the screen still won't light up. What other components could cause this? I know I can purchase a new power board, but if I can fix it, I'd like to.

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.

Vizio vp332 will not power on


It sounds like a powersupply problem. Bad caps on the board. I've found some vizios with bad caps along the aluminum heat sink.

It won't turn on


I replaced 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

I go to turn it on and the vizio label turns white then clicks off


The Vizio VP322 is notorious for having bad capacitors on the power supply circuit board. They will probably be bulging and may have electrolyte leaking. I replaced four bad capacitors (with a different brand just in case) and fixed it. Total cost under $10. A lot cheaper and better than replacing the whole circuit board which may contain the same "faulty" capacitors from the factory.

After about an hour picture gets a blue distortion. YOu have to turn off TV and let cool off. Once it cools off it works until it gets hot again.


replace these electrolytic caps in the power supply,
C233,C234 3300mf/16volt
C241,C238 470mf/35volt
C236 1000mf/25volt
you can also go to shopjimmy.com enter model number scroll down to find power supply if they dont have it in stock write down the part number to find it on the web,it would be cheaper for you to replace the bad caps.
