Power Problem (Phillips 55P8341 Projection TV)

I've got a Phillips Projection TV with an intermittent power problem. It turns itself off after 5 minutes of being on. Sometimes it won't even power up. The problem continues to elude me. Can anyone shed some light on the subject? my tv powers off after a couple of seconds... the screen never comes on. The power indicator turns from green to red. TV is 18months old

Same problem... I pulled out the second electronic board going from right to left and see a burned diode at position 3307. I wanted to know if anyone has a schematic of this TV and could tell me the numeric value of the part in position 3307. It would be appreciated it you could let me know.Thanks...

Tv turned off by itself now TV button goes on but immediately turns off


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

I have a philips big screen projection tv modul#55p8341 that turns off after being on for a while. great picture and sound


Your horizontal output chip is going bad after it heats up to a certain point it fails and shuts your set down. After a while if not replaced your set will fail to power up at all.

5 blinks, Sony KP-65WS500 stays up only with one CRT gun at a time....


5 times blinks shows White Balance error in tv. You need to adjust Screen Volts (G2) and problem will resolve. Screen volts controls located at Focus Block as shown in below picture.

Phillips model# 60p8341


Let me get this straight, you don't have a picture as long as the unit is on, but when you go to turn off a picture flashes? Questions, first how is the picture when it flashes briefly? Is it normal or with colors misaligned? How is the sound? Could be a loose connection or bad capacitor in the video circuit.
