    I have the same problem with my television and mine is two years old. The power supply is good. Is there any other solution you can give us.

    power is on, blue power light showing. initially clicks when you plug it in as it gets power. sound for a dvd will still go throught the tv to the stero but the tv itself will not show anything nor will the sound work.

My Philips 50pf9631d plasma tv turns on then red light blinks 7 times! Philips no help. Local electronics store wants $500 to fix! Set is only 3 yrs old! Please help.


Are you getting picture or sound at all? If not, you could have a very common power supply failure. If you get sound or picture, then you may have a faulty capacitor or resistor on one of the system boards

If you don't have any green lights anymore on the power supply PCB, replace it (part number LJ44-00118A, can be found on-line for approx $180).

Red light flashes


This is a well known and very common problem with all Philips plasma tvs 42 and 50 inch. The problem is they used under rated capacitors in the power supply. If you have electronics experience or a friend that is, remove the cover and look in the back for malformed or leaking capcitors. Replace them and see if that takes care of the problem. The caps only cost $2 or $3 each, so the cost to try this is pretty reasonable although you might have an added cost of buying beer for your electronics friend. If this does not fix your problem you are down to replacing boards that can be purchased around $300 ea.
I have found my set will come on "finally" after I get the back of the set warmed up and the bad caps finally charge up. Hope this is useful.
