Question about Philips 42FD9954 42 in. Plasma HDTV
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.

My system is FIXED!!! Great recommendation on EBE Electronics. Removed the supply, shipped it to them and it was back within a week. The system fired up like new and now enjoying it again. It is disappointing that Philips won't own up to this obvious design flaw. Just looking at the supply board you can see the problem... a bunch of electrolytic caps and lower temp rated components sandwiched by 2 LARGE heat sinks. Not to mention that fact that there is absolutley NO circulation for the supply. So much to read about this problem on line. $50 fix it kit on eBay may also work but I think the $300 cost by sending it to someone who has the right check out equipment was well worth it just in case it was something more than the caps (heat is suspected to bledd of the electrolytes) and the MC34067P IC which is the suspected problem IC. Good luck to all. Never buying a Philips again... but at least I have a working Plasma again....

To those of you using hair driers to warm up relays to keep tv on, each relay is fed through a highish wattage resistor. These can go high in value OR suffer dry joints where they are soldered onto the pcb. You could try resoldering them. This applies to any tv, monitor, or other display whether its plasma, lcd, or crt. Where there is a high wattage resistor, it can go dry jointed.

It has now been over 9 months and my phillips works fine. Ebcelectronics was the best choice. it was also the only fix i could find.

The switch was replaced by a large elctronics repair store. The part, each time, was always on back order. If you google the part number it will come up under various suppliers. I do not know why the last part no. has a decimal in it. I could not find it on the web. the idiots who have my plasma are still trying to jack me around. I faxed them a copy of the repair from ebc electronics. I guess I have to call the morons again. Sure would be nice to have my TV back after 30 days. That or pick it up and take it to a larger corporation who is capable of multi-tasking on more than one tv a day......

To Granky1...where did you get the replacement switch?

Same problem people, for months mine had been clicking. Then all of a sudden the red LED light just won't switch to green. I am thinking it is the Power Supply Module like you people said. Very frustrating!

I have had the same problem and my philips 42" plasma went completely out. a tv repair shop said the power board is $800 plus anothe $200+ labor to fix.
i found a guy at ebcelectronics that fixed my board for $284 plus shipping. he did a good job and had good communication. i was leary at first but i trusted him and it worked. look up ebcelectronics on google and he will come up. it even has a pic of the board that is giving us all the problems.
i now have a SCAVIO problem with the same tv and i have ebcelectronics looking at it. the scavio is the board that all the peripherels plug into.

Anyone of you thought about selling the tv for parts?

TriStateModule (www.tristatemodule.com) can your existing power supply board for $400 or you can look on ebay and sometimes find the power supply board. The part number of the power supply is: 312235721971 or 312235721972

Usually the electrolityc capacitors will cure the problem
