    Not very likely. You may have to consider the possibility that your projector TV has failed in service (is broken). One thought: if a cooling fan has broken, it's possible the TV is overheating after 30 seconds of use. Can you confirm whether you formerly heard a faint fan noise from the unit, and that you no longer hear it? If so, it will need to be repaired at a Philips service facility. Also, did you do anything to it recently, such as replace a projection bulb?

Jerryob03 is correct. And the most likely circuits to do this is the convergence amplifier circuit. A short there is a typical failure in rear projection tvs. In Philips, the protect cicuit sees this and shuts down the tv to protect other circuits.

Very unlikely to be the switch. With the power supply shutting down, the problem is probably in one of the circuits that is supplied by it. Unless you know what you are doing, leave it to a technican.

My Philips 51PP9200D/37 tv won't turn on. The lighted power button stays lite but nothing else happens. Could this be the Flyback transformer?


It could but it could be about 50 other things as well. You have a voltmeter, and know how to use it? going to need a service manual as well.

My phillips 60 inch tv 60pl9200d/37 wont turn on the power button flashes blue


Look in the manual. (Page 4)

Turn the TV on From main supply: Ensure that the main supply is turned on. A blue indicator light on the front of the TV lights up. When the TV is turned on by the main supply, the blue indicator light will blink for 45 seconds. This is the lamp's start-up period. When the light goes off, press the POWER button on the remote control or power switch. Press POWER to turn on the TV.

My rca d52w26 turns on for 5 minutes then shuts off let it sit for 20 minutes it turns on for another 5 any ideas


Try to cleaning it from inside first thing without switching it on as sometimes power is stored for upto 30 -60 secs (POWER SWITCHED OFF)- maybe alot of dust is gathered & messing with circuits, use a hair dryer or a cloth - then switch it on.
if it doesnt work then it maybe a fualty transformer - its difficult to know without doing a few checks.

good luck

No power just a chirping noise.


Chirping means the power supply is being loaded down by a short in most cases, likely a bad convergance IC
