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.

Bowed picture on Philips 55pp9352 after replacing IC's


You must have mishandled the ICs they are static sensitive, and unless you used Sanyo ICs then you will have problems. The convergence is obviously not working so the TV will need the digital convergence board repaired or replaced, also the PIP board is suspect I have seen plenty of these tvs and believe me I earned the $ 350 we charged. These sets are very difficult to work on even for a trained tech. the best thing to do is to have a repair shop do it and you will have the assurance that its done correctly, and the work is guaranteed, That makes sense. ( I will not be able to respond to any further inquires)

You shorted two or more pins when you soldered the STK chips into the TV. Re-Check your soldering.

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


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

Goto the site www.TvRepairKits.com and get their "chirping" tv repair kit. It will fix the no audio+no video + chirping problem.

A set beeping doesnt have to mean your CRTs are dead. Its more than likely something in your power supply. Do you have any diagnosis or soldering skills?

When tv turned screen is blank and chirping sound comes from back


A chirping sound usually means that one of the secondary supplies has shorted, most likely the horizontal output transistor. The power supply "chirps", which is the sound it makes when it protects itself from drawing too much current. The set should be serviced by someone with experience in Philips projection TV'.
