Hope this help in solving the problem....

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 on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others 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 $$$$$$$??????? (Is it under warranty?)

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.

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.

This may be your problem. If you determine that it might be.

I have a Tip/How TO 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. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

You are not the only one I can tell you that. I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board.

42PF7320A: 7 blinks is missing 8.6VDC from supply -- connector CN-1M46, pin 3 (out of 11 pins), goes from power supply to main/input board.

Hi, the power supply board has a little board towards the connectors. This board has an led and it will blink if there is an error, check how many blinks there are and then check on the on the power PCB next to this little board you will see the error explanation. Also check capacitors on the power board next to the control board connector, replace any bulging ones. I hope this helps.

I don't have a fix, but the same thing happened to my Philips Plasma and the V repair man tells me that Philips no longer make the service pack which contained all the parts required to fix the TV. Basically Plasma screens run very hot and the components on the main board breakdown. So when the power supply goes so do many other parts. Philips used to supply all the bits in a service pack so it would seem that they (Philips) knew all about this inevitable fault from early production.
I am livid and if you paid what I paid then you are probably livid too. I expected it to breakdown one day but I never thought that it would be impossible to fix. I would never have bought a plasma if I knew it was considered to be a disposable item by the manufacturer. It could be worse, apparently Samsung don't support their TV's after 2 years.
I am phoning Philips in the morning and will post the results of that call if they have anything positive to say.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck

All you can do at home is leaving the TV unplugged for one or two hours and see if this solve the problem.

If the unit has just been repaired, and it is faulty again, contact the service back and have the problem fixed.

Common faults on plasma TV can concert the PSU power supply board, the sustain boards, and other boards, wiring and connectors.
The testing and repair job must eb done by a technician.
