Philips 42PF9956/37 clicking relays

You posted the suggestion of replacing the capacitors 2540 (100uF@25v) and 2508 (4.7uF@50v) to fix the power problem. In my board, both 2540 and 2508 don't look like capacitors. They are very small and have P3 100 16v on top. They are equal. I also searched all the board but I couldn't find any capacitors at that values. Would you have another suggestion?

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

Failed Repair Job. A friend of mine called a loocal repair shop to fix their LG50PC3D 9 x 10V 3300uf 105c Capacitors on the Power Board were swollen 1 x 50v 680uf 105c Capacitor on the Power board was...


replacing the 10V caps with 25V caps is perfectly fine. In fact, if it was manufactured like that, those caps may not have blown.
Replacing a 680uF with a 1000uF could be problematic depending on it's function.
680uF is pretty specific when 500uF and 1000uF are much more common and therefore cheaper - one would think that the engineers would have tried using those in the design rather than a 680uF - makes me think the value of the cap is important to the frequency of the circuit it's in.
Other concerns might be whether he got any of them in backwards or not.
That's a rookie mistake, but still an easy enough one to make (for a rookie).
Also, with that many swollen caps, I wonder if there were any that leaked out the bottom before swelling at the top (IE - if some caps were missed in the replacement procedure)
Also, with that large a number of caps gone, other components may have been compromised or blown.
I'd be testing the transistors around those caps (most likely punched through rather than open), looking for fusible links (surface mount fuses, 0 OHM resistors) that may have opened up etc.
The initial attack on the problem was basically correct, and in many cases probably would have fixed it (if say the 680uF cap was functioning as a ripple filter).
But when that didn't fix it, a deeper analysis should have been done to complete the repair (including locating a 680uF cap).

Red light won't turn to green


This is a common problem. There are several capacitors on the power supply and logic board that are bad. Replacement of these parts has restore all units that I have looked at.

On the power supply I would replace at a minimum:
C14 - 4.7ufd 50v UPW1H4R7MDD
C4 - 1ufd 50v UPW1H010MDD
C8 - 100ufd 25v UHE1E101MED
C10 - 470ufd 16v UHE1C471MPD
C12 - 1000ufd 10v UHE1A102MPD

There are 4 others in the supply that were not grossly bad.
C1 - 22ufd 400v EEU-EE2G220
C7 - 220ufd 25v UHE1E221MPD
C11 - Same as C10
C13 - Same as C10

Logic board:
E5 - 33uf 35v EEU-FM1A471
E6 - Same as E5

Part Numbers of replacement caps are Nichicon or Panasonic.

Note: Caps on the logic board are extremely hard to replace due to the internal ground plane.

42" philips plasma, black screen and flashing red light


This fix was posted on similar problem, worthy of repeating: Replaced 3300mf 10V capacitors at PS. Both had bulged slightly. Upsized to 25V as the previous solution poster had suggested 16V but I could not locate 16V so used 25V and TV is back to normal!

IT SOUNDS LIKE YOU HAVE A POWER SUPPLY PROBLEM OR RELAY PROBLEM. BEING A 20 INCH SET IT IS NOT WORTH REPIRING. PARTS AND LABOR WILL BE OVER $100.

470uF capacitors


The 470uF/25V Caps are in the middle of the PCB alongside of the slab-looking aluminum heatsink. You should be able to see that the tops are popped up and the glue around them is brown from overheating.

Power issue


The Philips Plasma TV have a problem with electrolytic capacitors going bad. I believe you heated some capacitors and your problem may return. If so, try replacing 2540 (100ufd@25v)
and 2508 (4.7ufd@50V).
