Question about Philips 43PP9202 43" Rear Projection Television

1 Answer

Philips 55PP9352 Rear Projection, no picture or sound, chirping.

I have read several posts about a similar issue reported from other people. When the power button is pressed the red indicator light comes on and there is a chirping sound coming from the back. I have read some of the ideas on what could cause this, specifically the horizontal output transistor or Flyback. I have done searching but what I need to know is, what do these parts look like? Where would they be located, on which board? How do I test them? I can certainly replace them but I need help on the identification.

This is a common problem with this model. The convergence circuits have shorted out causing the HVG to chirp.

Chirping in a phillips is usually related to the HOT ( Horizontal Output Transistor) or the Flyback ( HV Generator having a issue.

Red power light on chirping beeping sound


Hello miko_alexand,

That problem indicates that the Horizontal Output Transistor (HOT)is beginning to malfunction. I would suggest that if you have a background in electronics that you do the following:

1) unplug and open the back of the set

2) look for the HOT and locate the Collector, Base and Emitter of the transistor and using your multimeter set to read resistance measure from the collector to the ground, it should read high almost infinite, red from base to ground it should read low and from emitter to ground it should read low.

3) if the HOT when read from the collector to ground reads low then you can bet that the HOT has a short circuit from collector to ground, and will have to be replaced.

4) In addition I would also perform a ring test on the Integrated High Voltage Transformer (IHVT).

This will tell you if the IHVT has suffered any damage from the HOT malfunctioning. You may end up having to replace both of the components.

If you do not have a background in electronics I would suggest that you take the TV to your local TV repair facility.

Thank you,

Mine had the same problem. It turned out it was the power board that went out. The ic's might need to be replaced again, because they could get whacked out when the power board blows out.
