Try a hard reset to this set first. If it do not help you, its SMPS circuit should be checked. There are two types of reset to TVs. The first is simple to do; a Hard Reset; and the other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Probably the power board capacitors if you are confident remove the back and look for blown capacitors on power board they ate round cylinder shape with silver tops usually are they black colouration or bulging replace the with exact same parts and it should be fine. it would be the one the power cable is attached to if you are competent you can do for a few pounds /dollars good luck

SOURCE: Phillips 42FD9954 plasma will not turn ON

I have a Phillips 42FD9954/17S and every time I try to turn it on I also get the power red light blinking and sometimes it will try to turn on with a bunch of clicking noises and it will be green for a while then turn red. What I do and its very weird but works, put a blow dryer on hot and blow it under the tv on the side of the power button for about 10 minutes and it will turn on. I took it apart and there is a heat sink that if i put the blow dryer directly onto it on heat it turns on in less than a minute. Can someone tell me how I can fix this heat sink? I cant take it off. I want to put some thermal compound to see if that works. Give it a try I promise it will work. The Red Light has to be on put the heat on it and then press the power button, if you hear it clicking and green then back to red you are almost there. Keep putting heat on it and it will turn on.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

I have a 42" LCD


Some of these TV were equipped with very short connections from the infared board to the small signal board. Remove some of the shrink tubing from the wires of the IR cable to relieve stress on the individual wires. Trim the other end of the cable as well. We are talking about one half to three quarters of an inch.If this does not help you will need to order a new IR cable. Please show this info to an authorized Philips dealer and have them do this for you. Thanks for asking and show a few hands of support.
