1) Replace C2663 by 2020 021 91677 (100uF/50V, 105°C).
2) Place Schottky diode 9336 247 60133 on pin 7 (+) and 8 (-) of IC7650,
to avoid negative pulses, resulting in this bad startup behaviour.

You might have some swollen capacitors on your power supply board. They will be easy to spot out, because they will not have flat tops like the rest of the capacitors. Replace them with the same rating capacitor. You will need a soldering iron, solder and solder wick for this repair. If you are not comfortable with electronics I would recommend taking it to a authorized service provider.

Are all the caps good on the PSB.? Most sets have Samy boards and they used very shotty capacitors. Some show NO visual clues of being blown as in poped at the (X) top. They just vaporize/dry out. Do you have a cap tester?

Best Regards and Semper Fi

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).

Philips Plasma NO LIFE

I had the same problem (with 42FD9954/17S) that when turned on the unit, the green LED turned off and came back to red again some time later. I kept turning it on and once it went to a clicking relay sound and blinking green LED with it. It did that for a while and stayed turned on. I noticed that it is temperature sensitive. Colder the room is more often does it. Used a hair dryer and blown hot air into the unit at the left bottom grills. It helped and started to tun on quicker. Later it has deteriorated so bad that I took it a part and after several ice spraying test showed that on the middle big board (power board) there was an electrolyte condenser went bad. It is the one one which is at the middle, bottom center of the board near the fixing screw. There are two of them (cylindrical objects). The left one was the culprit. However when I fixed it, it turns on immediately but goes blinking red after that. Phillips say it is a static discharge problem. I might blown something when soldering the parts. I don't know what. Any ideas?
