!!!HELP... 2007 Philips 50PFP5332D/37 Flat HDTV - NO POWER!!

by manwithnoname6 - 9/6/10 11:07 AM

Hello - I am new to this forum, so hopefully I am posting in the correct area within the site (if I am not, then please re-direct me). I am looking for some assistance regarding a problem with my 3year old Philips 50" Flatscreen Plasma TV. When I was watching the TV the other day, the blue LED light on the front panel turned red and then it powered itself off. Now, there is no power with the TV (e.g., will not turn on, no LED lights at all, no clicking, no sound, no video, etc.). The TV has occasionally turned itself off in the past, but I have always been able to wait a few seconds to turn it back on (or worst case, unplug it to reset it).

I reviewed some threads in the forum that are similar to the issue(s) I have with my TV, but I believe my problem may be different altogether (the other threads referenced blinking red LED lights, or green lights).

I reviewed the following tutorials / articles that outline issues with the capacitors, which could be one of the causes of the power failure with my TV:

cheatzona.com/philips-50pf9731d37-50-in-plasma-tv-repair-bad-capacitor.html

I took off the back panel to my TV, and the capacitors look good to me (e.g., no visible bulging or abnormalities). All other visual inspections of the panel looked good, other than some dust build-up. I also tested the power cord, and even took it to a local electronics shop to confirm the cord is functional and there are no issues with the cord. I have the TV plugged in, and there are no lights, no sounds, etc. from the back panel.

Does anyone have any recommendations with what my next steps should be, so I do not waste any more time, energy on this TV? Would a blown fuse cause this type of power failure? Should I still try to order the capacitors and replace them to see if that works? Is this most likely a larger problem with the power supply / board, that probably needs to be replaced altogether? Are there other potential issues that could be causing the problems (maybe it is no power supply related???)?

I know it is difficult to diagnose something over internet. Again, since this is my first post, please advise if more information is required (pictures of back panel, etc.) My goal is to try and fix the TV myself (if possible) or have it taken it in, provided it is <$300-$400 to fix. Don't want to scrap a 3 year old TV that I shelled out $1200 for three years ago. Thanks to all in advance for your time reviewing my case, and any feedback / assistance you can provide.
