I looked around for a power supply for you and turn up nothing. I see your problem. Nobody is selling. Best just to fix the board itself.
What I would do is get a Service Manual over the internet. Nodevice.com is selling the Service Manual. Usually cost under $20. It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, schematics, test points, and part number lists. And most cases the new part cost less than $15 by searching on the internet with the part number.
It's possible that it's just a bad capacitor or transformer on the power supply board. Cheaper than replacing the board.
I hope I solve the problem for you.

Not a fix, but it got my tv on.
I removed the back and tried the power switch.
I located the relay that was clicking.
I have two blue relays in the middle of my power board.
I placed a hair dryer over the relay for a few minutes.
After four tries of the power switch and it stays on!!!!!
Heat keeps the relay from just clicking off.
I don't know why.
This will at least get the tv on though.

My Hitachi tv model p42h401a will not turn on. The "standby"light is not on either. I have checked the power supply and that is working.

Have you opened the actual TV and checked the power supply board inside? Because that is what it is. You need a new one.

2006 42" plasma has blank

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

My 50 inch samsung plasma tv turns off and on by itself. it also clicks while this happens.

My Samsung 52" plasma TV will shut off while watching TV. It will do it repeatedly and we have to turn it back on. Is it overheating and shuts down? How can this be fixed?

Missing power cord

HELLO AND NO YOUR AMP SUPPLY IS'NT THE RIGHT AMOUNT YOUR CORD ONLY SUPPLIES 2.5 AND YOUR T.V. CALLS FOR 5.2 IT'LL RUN YOUR T.V. BUT THE REASON IT WONT WORK IS BECAUSE YOUR T.V. WILL PULL 5.2 AMPS AND YOUR CORD IS ONLY RATED FOR 2.5 IN TIME THE CORD WILL BURN OUT OR GET HOT AND CAUSE A POSSABLE FIRE.

42" Toshiba Plasma TV no picture or sound

My experience with 42" plasma tv's with no picture or sound was a missing power supply voltage. On the power supply board check voltages on the plug. The voltages should be marked on the board,
