Question about Philips 42FD9954 42 in. Plasma HDTV
I had the same problem with my 42FD5994. It was working fine, then one day I turned the TV on and the front light turned green for about 5 - 10 seconds and then the TV switched to protection mode (front green light is now red and flashing constantly). I did some research and found out the the power board is faulty. I ordered a DIY fix it kit on Ebay for around $55 (includes shipping). The kit contains 5 high temp capacitors and a new IC chip. It also comes with a good detailed photo of the circuit board the components that needed replacing.
I also spent $70 at Radio Shack for some soldering gear and went to work. It took me 3 hours to replace the 6 components. The IC chip was a pain to remove, but one that was out the rest went pretty smooth. I had to remove two extra blue capacitors in front of the IC chip to desolder some of the leads.
After I cleaned the board with Isopropal alcohol (99% pure) to remove the excess flux, I inspected the solder joints to make sure I didn't solder some runs together. All looked good.
Next I put the TV back together and hooked everything back up. I powered on the TV and the same problem as before. The TV went into protection mode. But this time I heard the speakers pop and the screen buzzed. So I pushed in the power button to reset the TV. Next, I turned the TV back on, but this time when the light was green, I quickly pushed the power button again to power off the TV. I tried the TV one last time. I powered the TV back on, and with the remote I turned the TV on. Viola! It worked. The TV powers on great, and works like a champ. I am guessing that the first time I tried to turn the TV on, the new components needed a minute to energize. I also started the TV cold, I should have plugged it in for a few minutes before I tried turning it on.
So, I was successful fixing my 42FD5594 with the DIY kit on Ebay. I ordered it from California. The company was great, and Everything arrived well protected. I figured if this didn't work, it was time to get a new TV anyway. I can save the $2000 for another day.

I had the same problem plus others . Cost me $550 to get a new power relay. Got it home and whilst it is working, I am experiencing the turning of and red flashing light. Have been advised that it may be that the plasma cannot cope with the signal. Have yet to try it yet. I have been advised to lower the resolution from 1080 to 720.
