Question about Philips 55PP9363 55" Rear Projection HDTV-Ready Television

1 Answer

Philips 55PP3363, No Picture, constant Chirping / Squaking.

The TV was recently moved and would not power on at all. When I opened it up I found 1 fuse socket empty right where the power cord enters the chassis and the other half way dislodged. I re-seated the dislodged fuse and replaced the other fuse with a 250v 4amp slow blow fuse (TV specs show 255watts, 4 amps is probably too much) Now, upon pushing power on, I hear the system power up, and it starts to chirp. No other picture is present. Suggestions? Thank you, TJ

I will assume that one of your fuses had blown. I would venture to suspect that this set was worked on before. What you are hearing is the startup circuit trying to turn the Horizontal oscillator on which will then turn on the High Voltage system on that provides power to the rest of the television. If this is the case I would consider looking at the HV section to make sure things are ok there. Then I would test the HOT to make sure it was not shorted. If it is shorted then you have to test the HOT related components for defective values. If you are not comfortable doing this contact a TV Repair man and inform him of the situation.

I have a philips 9p6044, and there is no picture or audio. It has power, but there is no display or sound. What can be the problem?

On that model if its making a constant chirp sound while powered on? If so then its most likely a convergence failure.

If its not chirping then the next most common failure is a power amp. Both are realtively easy DIY fixes. The website has complete kits for both. Hope this helps.

No Sound, No Picture on Magnavox 51MP392H/17

If you have no video - but have audio - its most likey the HVG.

Note: When the video goes out sometimes its hard to tell if you have audio becuase you can't see the screen to change to the correct channel.

Phillips chirping

two STK392-120 convergence modules that usually cause the beeping. So I changed them both again, but I also found two open 7.5 ohm resistors are in the general area of the convergence modules, and I replaced them as well. I also replace 1 swollen capacitor that was probably going to blow in the future but not really a problem yet.
