Hey I have the same problem with my 42fd9954/69s. The best solution that I found that works everytime is I have taken the back off my plasma hung it on the wall. Then when I need to turn it on I it starts clicking, so I get my $10 room heater and blow some hot air down the back of the tv from the top and 30 secs later the tv will turn on.

Too easy. Bit dodgy, but I am a uni student!

Unplug the power cord at the back of the unit. Wait 15 seconds, plug back in and try again. I got lucky - it restarted.

I have a phillips 42fd9954 17s. when i turn it on the green light tuns on for like 6 seconds then fades . then nothing. no sound no picture. any idea. i am using a comp cord. had no cord when i got it


if you use vga input and there is no signal the tv shuts down in few second. It will wake up again if you provide vga signal or cycle it on off again. Change input to component or s-video and tv should stay on. On the other hand, this model has known problem with bad power supply unit but usually red light flashing when tv shuts down in that case.

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.

When I turn on the unit I get a green light, but after about 5 seconds it switches to red blinking and I do not get a screen


What is the model of TV?

The Red blinking light is a Protection Error Code. Your Tv needs repair. Most common is the power or Main Unit / Logic Board.

Post your model and how many times the light blinks. Also try unplugging for about 20 min and see if it will turn on.

Some models you get lucky and its a common problum which makes for an easier diagnosis.

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?

Hi, and unfortunately I am facing the same issue. My TV blinks GREEN LED for a few seconds then starts flashing RED led. The result I hear from this is that it is the SSB Panel and the estimated cost for service is $600.00 it sounds like you are STARTING with the problem. I began that way too. If you are under warranty, call Philips NOW!

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?
