Power supply is bad on philips plasma 50 inch tv, it just clicks

More specific, please ! Finally, did you replaced all bad capacitors or only replaced the power supply unit ? Because there are many other capacitors on other places that can be damaged.
Sure, the problem seems to be from one of the capacitors, but you have to know how to find the damaged one (and with the proper instrument will be more easy). Howewer, to buy a good instrument is more expensive than to service your TV set (my opinion). Plus guaranty.

Most Common problem is Bad Capacitors on the power supply board, they will be vented or swollen on Top. 1000uf 16v 2200uf 10v 3300uf 10v

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 ofcourse) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts 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. Checkfor faulty caps. If you find some (bulgedor leaking) bad caps replace the entire board. The entire board costs around $250 right nowbecause they are in high demand right now. They can be found at tv-part.com but supplies are limited.
3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
I have a tip/tutorialon this site that may also help. Itgives 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/shutsoff on its own problem. I'mworking on uploading pictures to help guide people though the process aswell. Let me know if I can do anythingto help. Hope this helps and Good luck. Kaufman605

one day not start his open. stan by red led and after switch on ,his green bligkig is not open.sound is ok.(the relay his not click)

Power supply board have dead capcitors.Know how to solders?These capacitors usally bulge or pop open,replaced these capacitors will solved this problem.Or tries websites Shopjimmy.com,Ebay.com to buy a Whole reburbish power supply board for the replacement.

Most Likely the power supply board has a few capacitors blown.You can repair it by removing back cover power supply board will be at the center of tv.Look for caps that have a round top these are the bad ones replace with same value caps.You will have to take power supply board out.Be careful these power supply boards have alot of voltage store in them.

I have the same tv and the fix was the power supply board that had 5 capacitors that were blown. there was a black goo on the top of the capacitors. The power supply board is in the middle top of the tv once you pull the back off. replace the bad caps and you should be back in business. My 50 inch plasma fix costed $5 in parts (5 capacitors) and $9 in shipping fees. Much better than the repair shop. If you know someone who can solder for you or if you can do it yourself, it's very easy to fix.

I bought my Philips Magnavox 50" plasma in June of 2007. In february of 2009, I noticed increasingly longer delays in the video coming on after turning on the power and then the audio began to delay coming on. After a few weeks of this problem the audio and video then stopped coming on at all. However, there was power going to the unit because the green power light was working. I noticed over 50 other consumers on this website had the same problem. WITH THE HELP OF OTHERS ON THIS WEBSITE, I HAVE FIXED THE PROBLEM FOR $40. YES, FOR LESS THAN $100.00 I HAVE A WORKING HDTV AGAIN, BUT WITH NO THANKS TO PHILIPS - MAGNAVOX. THEY WERE USELESS. 

HERE IS THE FIX:

1. Unplug your power supply cord.
2. Remove back panel on your HD.
3. Look for capacitors that have a bubbled or slightly raised and rounded top. This indicates the capacitors have overheated or leaked and need to be replaced. The normal look is a flat surface with no raised features at all. (I had two bad capacitors that were side-by-side and identical: 3300uf 10v. Also, they should be located on the power supply board. My power supply board is in the middle of my 50" plasma.) 
4. Go to an electronics repair store or Radio Shack and see if they carry your capacitor type and size and replace them yourself if you are comfortable with removing the capacitors and soldering new ones to the power supply board. The capacitors will cost you $2.00 each or less. 
5. I was not comfortable replacing the capacitors myself so I removed the power supply board by removing the screws and unplugging several wire connections. This was not difficult at all. I then brought the power supply board to a local electronics shop that did repairs on HDTVs and simply asked them to remove the bad capacitors and solder two new capacitors onto the power supply board. They did it for $40, which included cost for the 2 new capacitors, while I waited and it only took about 10 minutes.
6. I replaced the power supply board and back panel of TV and it worked!!!

Some people on this sight suggested replacing the capacitors with some that have higher temperature ratings. Based on that advice, I wanted to replace my two that were bad (3300uf 10v) with two rated at 4700uf 35v, but my electronics guy suggested against it. Instead, I replaced mine with 3300uf 50v, with the only difference from the original parts being the higher voltage (50v instead of 10v). I figure if the problem occurs again, I now know I can get it fixed for less than $50.00. Philips - Magnavox should be ashamed for such poor customer service and not telling people about this simple fix. When I called their customer service support number I was simply directed to a repair place --over two hours away!!! 

change your power module.
thanks
