Philips PLASMA TV 42PF9956/37 42" power board 3104 313 60173 relays clicking TV does not turn on

I have a Philips PLASMA TV 42PF9956/37 42" that does not turn on . I checked the web site solutions and "pizzaguy" suggests to heat these relays with a hair dryer to have the TV back to work. Well, I tried heating them and the TV worked for a few hours only and now is clicking relays again. Alternatively "I AM I" sugests replacing the capacitors 2508 (4.7 uF @ 50v) and 2540 (100 uF @ 25v) My TV's power board is part nbr 3104 313 60173 and the 2508 and 240 are not capacitors. My poor electronics knowledgedid not recognize them. They are equal components, marked P3 100 16v on top. I also searched the board, but I couldn't find any capacitors at that values. pics attached.

    Thank you cluxdelux. You are the best!!! We replaced the capacitors and the TV is working good. Instead of buying 100 pieces @ US$15 + S&H from the link you sent, we went to garret web site and found 50 pieces @ US$10 + S&H (that is their minimum order). As we only used 4, we have 46 capacitors left for anyone else who has the same problem, since I know how it hurts.

    my uk philips 42" went off and came back on again. then the on/off switch stopped working and of late we had to switch it on at the socket, somtimes it worked all day other times it took up to half an hour to get it to fire up. Now it does not work.I know it has to of gone down on the power side and reading this thread it seems this could be the answer. I noticed this fault is very common with nearly all plasmas.Help.

    I have the same problem with my 42PF9956/37 42". I just ordered the Rubycon capacitor. Can anyone give me a quick "how to" on replacing the capacitor? I am a novice at soldering. Will replacing this capacitor be difficult?

    Were the caps labeled right? How did you solder them, with iron or paste? I am looking for a little guidance. I have experience soldering just never on a tv circuit board before. Thanks Nick

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

Cluxdelux solution worked!!! Soldering the surface mount capacitors was a lot easier than I thought especially considering that was the first time I ever solder. I do recommed checking out YouTube for quick soldering lessons. The only thing I wish I would of done different is purchased a soldering iron that was a little thinner. It was tough getting to capacitor 2508.
Highly recommend this solution. I just looked at another 42 at Best Buy today for $900. It is hard to believe I fixed the problem on my own for less than $50. Its a good day.

    we need caps! See above.

  • john3012 Aug 17, 2009

    Ashmouth and cluxdelux are right! PCE3750CT-ND works. Thanks! I just
    got my caps soldered in and this free TV is awesome. I spent a total
    of ~$42.00 on repairing this 42” plasma. $9.95 on caps and shipping
    from Digikey, $16.77 on a candy bar, antistatic gloves and bags, and
    $15.89 on an 18 pack of Coors Light for the guy I found to solder it.
    If you **** at soldering and want to find someone to do it in your
    area, go to the SMTA website, find corporate members in your area and
    contact them in regards to SMT rework and repair services. It worked
    for me! I have 10 panasonic caps if anyone is interested?

We had the same problem with our Philips 42 inch plasma TV. The whole red blinking light problem that everyone talks about. I was ready to put the TV in the garage and try and figure some way to get rid of it when I decided to call Sears. Sears came out and replaced three blown capacitors (probably less than $15.00 worth of parts) for $220.00. At least the TV is fixed and didn't become a garage ornament.

My 50 inch philips plasma tv wont come on. all it does when you turn on the power is that the blue light comes on like usual and you hear a relay click and then a few seconds later you hear a relay clickin...


There are a few common gotchas for all plasma TVs:

Most commonly, a sustain board overheats and burns out; sometimes that prevents the TV from powering and sometimes it does not.
Unfortunately I don't know enough about your particular model to tell in which category it falls.

Second, the power board either breaks too (sometimes as a result of a sustain defection) or filter capacitors on it dry out and prevent the board from powering on properly. This, in turn, is detected by the protection circuits on the power board itself and treated as a short circuit, thus shutting down the board to prevent further damage.

In my experience 80% of the time the problem you describe is caused by burned ZSUS board and 20% are due to defect power board.

As I said earlier when a sustain burns out it sometimes takes down the power as well. Which is to say do not presume that just one board has gone bad.

One of these days I am planning to post a DIY troubleshooting guide for plasma TVs at my site http://www.coppelltvrepair.com .

It's easier than many people think.

For example in your case I'd try to power off the ZSUS board - the one on the right side of the TV when you watch from the back - and turn it on again. If it powers on then the problem is in the ZSUS board.

In fact, there are quite a few such guides circulating around the net.

The problem ,of course, is that it takes time to understand and apply them properly.

Unless you have a lot of time to kill or a desire to enter the field of TV repairs it's usually better to just pay off a good technician.

Developing the qualities to find a good specialist is a challenge well worth the time and will pay many times in life.

The same can not be said very safely for the qualities of repairing plasma TVs :-)

Power button comes on but no sound or picture


change the resistor in the relay circuit as they go high in value

also when you take power supply panel out check all caps for bulges etc.

Philips 50 Inch Plasma Model 50PF7320A/37 will not turn on


Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

42FD9954 philips plasma TV flashing LED it wont come on


The problem is in the standby power supply. the standby power supply generates the 9 volts and the 5 volts requird by the tv. If you measure the 9 volts source, with only the red light on, the correct voltage is 9 volts. However if the 9 volt measures 6.5 to 7 volts it is too low and the startup relays cannot operate. My set is a model 42FR9954/17S. In this set if capicator, 2603, is heated the voltage climbs to 9 volts and the relays work. If cold air is applied to the capicator the relays fail to operate. Replace capacitor 2503 and the problen is fixed. This capicator is: 47 Ufd, rated @ 450 volts, and is 20%.

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).

42PF9956/37 SHUTSDOWN...


Ok. I got my tv back on.
I pulled off the back cover and found the relay that was clicking.
I have two blue relays next to each other that click when the power is pushed.
I placed a hair dryer over the relays for about a minute.
Once heated up, it only took 4 tries to get the TV to stay on.

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.
