Question about Philips 51PW9303 51" Rear Projection HDTV-Ready Television

2 Answers

Chirping and not coming on

The chirping is more like a cricket and is 17 chips at 10 seconds. There is no smoke or smell. Sounds like its coming from the bottom right side of the tv (looking from the back) and the only light that comes on is the light in the power switch.

    If I purchase the convergence amps (7044 and 7045) will I be able to tell where they go if I don't have a schematic for my 51PW9303?

    I think I have the same problem, but I'm not sure what parts you are talking about replacing. When I try to power the tv on, it makes the chirping sound and no picture. It's a chirp per second or there about. And it never stops or pauses.

    When the Convergence Ampa go out the set willmake a chirping sound and the set will not come on.Also the HVG (5904) 312226832865 could be defective also that will be the only 2 reasons for the set not working.

  • Lawrence Smith Aug 19, 2008

    There are no instrutions on replacing the baord it is easy just make sure the set is unpluuged. Put it together the same way you will take it out.If you came do a computer this should be a piece of cake.

I have no pic or sound except a chirping noise , sounds like a cricket , LOL , timer light stays red , there was a odor , like a burnt smell


Hello. The chirping probably indicates a shorted transistor or diode, and the burnt smell usually indicates a blown capacitor or a burnt resistor, or multiple damaged parts. I would have to see the TV to be of any further assistance. Sorry I couldn't be more helpful. Good luck.

TV MAKING A CHERPING OR CRICKET SOUND AFTER IT IS TURNED ON


Two main common failures for these sets is the convergence amps and the flyback transformer (which is rather expensive). Both can make the set "chirp".

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

The chirping is an indication that the power supply is having difficulty starting up. This could be a problem with the power supply itself or a problem further down that is loading the supply. For a set this size, I'd invest in a detailed repair estimate. Report the results here and we can walk you through the actual repair.

No picture, no sound, just chirping noise coming from back


NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...

Zenith iqc50h95 50 in rear proj


Rainman, can`t really be of any great help on this one, both techs can be right, the chirp is exactly as you thought, the set is trying to come on but there is a short in the set and it`s shutting down because of the short, could be convergence, low voltage power supply, high voltage power supply, until a tech gets in there and starts un-loading circuits it`s impossible to say where the short is, gonna have to call someone out for this one, good luck with it, BMW Rider
