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

by manwithnoname6 / September 6, 2010 4:07 AM PDT

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:

recycledpapyr.us/2009/03/26/blown-power-supply-on-philips-plasma

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.

Same Problem

I have two of these TV's purchased from Wal-Mart. Bought first one in Nov. 2007 and it went bad June 2009. Bought the second one in March 2008 and it went bad yesterday Nov 2010. The first one would shut off by itself all the time. Then one night it just shut off and never came back on. The second one starting clicking upon start up and would just click away. I would have to do a series of unplugs and plugins to finally get it going. Last night it finally shut off for good.

I also have the back off the first one and see no signs of capacitor problems. So I will keep surfing and see if I can find anyone who might know where to look for the fix.

Everyone I spoke to says $400 min. to fix. So that is $800 to fix 2 (minimum) or throw them away and by a new LCD for about $900.

Always but imports when it comes to cars and electronics.....America is just so lost when it comes to products and customer service.

About bad caps.

I'm finding some to need a little help in identifying the bad ones. Let's just say that unless the cap looks like new without the slightest doming of the top then it might be good. But the BAD CAPS issue is a plague. The symptom you noted is wide spread with this being the cause.

I had the same problem. Watching TV one day and click the Tv just turned off. It had no blinking lights of anything. After a week if thinking "I can't believe this TV is broke and no one around here to fix it" I tore the back panel off. Two fuses in the back seemed to be the only thing that I could see to replace without doing a major repair. A green fuse and red fuse. Replaced those and it worked. They are located on the center panel in the bottom corner of the panel. Hope that helps.
