Question about Philips 42FD9954 42 in. Plasma HDTV

1 Answer

Similar problem My set is a 42PF9966/12 and my psu board 3104 313 60173A. I have tried replacing the 2533,2540,2541,2508 capacitors and the 2616 that looked like it had leaked out on the board, replaced the 2617 also just in case. This have not have not helped sadly, the screen still goes black after about 20 min. I then got a can of cold-spray and after the screen had blacked out i started to spray on various places and when i got to the upper left corner the screen came back on. I have now narrowed it down to the components 2674 and 2675, also have a buzzing sound from the 5600 component that gradually gets more and more noisy until the screen goes out, but when i spray on the 2674, 2675 the buzzing stops for a while. Is it the 2674,2675 that need replacing or is this a indication on something else beeing wrong.

Hi,

I'm sure the board needs to be replaced. An outright replaced would do the magic.

Kind Regards

How do I know which board to replace on my Samsung Plasma TV


look for the board with coils and big capacitor on it. that will be your psu (power sapply unit) the image below is not your board but just a refrance as to what a psu "can" look like. try "googling" PSU board with your tv model.

Mitsubishi tv wd-82738 no power


Most of these TV's have switched mode power supllies that run very hot. There is a likely chance that the capacitors have cooked (burst) on the PSU board. They are common capacitors. Open up the TV and with the mains electricity turned off, check the 'X' on top of the tubular capacitors. If they are bulging, rather than flat, then unsolder them and replace them.

I've repaired many of these sets because of this problem.

Won't turn on


b7d051c6-2386-46f1-9de1-bf708dde078e.jpgThis is often caused by failing or failed capacitors in the power supply unit (PSU). In my case I had a Lexsor 32 inch LCD flat screen (psu part number KAS200-5S241812XS VER A2.1) but these notes probably also apply to any number of similar LCD flat screen TVs with similar problems. Make sure and double check the values of any components you replace against your own TV's. The component values I have given are just for my make and model of TV.

Naturally these instructions should only be used by fully competent persons who know what they are doing and anything you do is entirely at your own risk. If you do not feel competent to look inside your TV and do the repairs yourself then maybe consider printing these notes and giving them together with your TV to a fully qualified and certified TV repair specialist.

Here's what happened to my TV and how I fixed it:

The blue front light came on when my TV was turned on but there was no display or sound. Sometimes repeatedly pressing the on/off button many times finally got the TV to turn on but it made a buzzing / hissing / static crackly noise and it took many minutes until the LCD display and sound came to life. Eventually even repeatedly pressing the on/off button failed to work and only the blue light on the front panel came on with no other activity.

CAUTION: MAKE SURE YOUR TV IS UNPLUGGED FROM THE MAINS AND *NOTE* THERE ARE VERY HIGH VOLTAGES THAT MAY STILL BE PRESENT INSIDE THE TV EVEN AFTER IT IS SWITCHED OFF AND UNPLUGGED FROM THE MINS POWER SOCKET. TAKE VERY GREAT CARE NOT TO RECEIVE AN ELECTRIC SHOCK. MAKE SURE YOU REALLY KNOW WHAT YOU ARE DOING *BEFORE YOU DO ANYTHING*!
I opened the TV and located the PSU board (see photo). Six of the electrolytic capacitors were clearly puffed at the top (your TV may have a different number of capacitors that need replacing). They should all have flat tops so if they look "puffed up" (a bit like a bottle of fizzy pop that's been shaken) then they need replacing.
Please note that in my PSU three of the capacitors were orange 25v 680uF electrolytic radials and three were black 35v 680uF electrolytic radials. I un-soldered the capacitors from the board and replaced them all with 35v black 680 uF electrolytic capacitors (I reckon the few extra pence the 35v ones cost instead of the 25v ones is money well spent!)

Re-assemble the whole thing and - there you go - I hope you are as lucky as me and your TV is as good (or better) than new!

Happy viewing!

Our tv when itis on for a while some times the picture freezes an then goes blank an a loud hissing an squeech sound we have to unplug it to turn it off.


Hissing sound normally from Power Supply unit(PSU), usually from Transfomers in the PSU. Usually caused by bad capacitors. Try this capacitor replacement kit, on ebay only $15. http://www.ebay.com/itm/Repair-Kit-RCA-L32WD22-LCD-TV-Capacitors-/230637983468?pt=LH_DefaultDomain_0&hash=item35b31856ec

Could not find any PSU board available at the moment, but have tried that kit and it works.

Will not power up. Replaced bad power supply(burned circuit board inside PSU) but still does not power up, PSU is ok. When power on button is pushed CPU fan turns for about 1/2 second but nothing else....


Sounds to me like when the power supply went out it allowed a surge to hit the mother board and you will have to replace it also .Look at the mother board and see if there is a green LED light showing if it is you are getting power to it and you have capacitors blown if not recheck you connections from the power supply and MB if they are all tight and correct then just figure on replacing the mother board

When I put the plug into the PSU for my sony tower pc the green indicator light just keeps flashing. Now when I unplug the 24 pin connector from the mother board the light on the PSU is steady green. What...


the PSU has Problem . It is not supplying enough voltage to boot the PC, capacitors inside the PSU are weak or damaged. Its dangerus to open the PSU coz, Capacitors have high voltage currents. If you have the Knowledge of electronics, then open the PSU and detect the Weak or Leeky Capacitors and replace them with new one( this method is for experiment and thrill) . But the replacement new PSU is better , perfect and cheaper then repairing the psu from outside. best of luck

T.V. was on several minutes later the sound and picture disappeared. Tried troubleshooting in manual but nothing worked, what should we do now.


The unit senses a fault in the power circuit. It is either in the power supply unit (PSU) peripherals or in the PSU itself.
  • One of the peripherals might be loading down the PSU causing it to shutdown.
  1. Check the power input terminals of the peripherals for any short circuit using an ohmmeter.
  2. Replace any part found to be causing the issue.
  • The power supply unit cannot run under load and shuts down. It is usually caused by bad capacitors.
  1. Check the PSU board for any bad capacitor.
  2. Replace bad capacitors with the same specifications.
  3. Make sure to replace the capacitors in correct polarity.
  4. Bad capacitors look like these:3a72a3c.jpg17dffa0.jpg

I have a 30 inch prima/arrow lcd tv which powers up but doesnt remain on for longer than 20 seconds


The tv is probably pulling too much power and so shuts off. Does it have picture and audio before turning off? Are there any blinking lights or anything after it turns off? Unless I get a blinking code or anything, a person with electrical experience is going to have to narrow down the problem since the tv shuts off to protect itself. Could be the power supply or a number of other things. One quick thing to try is to plug the tv into a surge protector or if it is in one, plug it directly into the wall and see if that changes the time it takes to turn back off.

Vertical bar on Daewoo Plasma screen


The main problem of this model is VPB (video process board) and the reason is they build in it SMD capacitors and they are always crap.First thing that you guys should do is to replace them all but not with SMDs,get a normal capacitors same values.And of course replace all capacitos on PSU.Parts are cheap to buy about 30euros,work on the PSU is easy,only the VPB is tricky but it can be done.It only takes time but belive me don't even think of board replacament its cheeper to by a new set
