Not a fix, but it got my tv on.
I removed the back and tried the power switch.
I located the relay that was clicking.
I have two blue relays in the middle of my power board.
I placed a hair dryer over the relay for a few minutes.
After four tries of the power switch and it stays on!!!!!
Heat keeps the relay from just clicking off.
I don't know why.
This will at least get the tv on though.

The capacitors for 2533,2540,2541,and 2508 should be replaced. They are all 100uf 16v surface capacitors. Those capacitors are sold on amazon.com http://www.amazon.com/Rubycon-Electrolytic-Capacitor-IMPEDANCE-Continuous/dp/B0015A8U9M/ref=sr_1_2?ie=UTF8&m=A6Q8GCHJGURD6&s=industrial&qid=1225140147&sr=1-2

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

42" Fujitsu plasma. Picture went out and the power


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.

Philips 42 42pf5520d faulty


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 have 42 plasma tv that makes a clicking noise then show 8 blinking red lights anyone now whats the problems my model # 42pf9431d/37


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.

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.
