My 50 Phillips Plasma TV will not turn on. It just makes a clicking sound and blinks a blue light.

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
