SOURCE: convergence point problem on a Philips TV
The 55pp9352 model number uses 2 of the STK-392-120 convergence chips--if it will not adjust in some direction--both chips and any of the 6.8 ohm resistors around them that are bad need to be replaced.
The reason this happens is the chips are about 2 1/2 inches wide X 1 1/2 inches tall with a metal back--they are attached to separate metal heat sinks and a white grease is applied to each to transfer heat quickly---after several years the heat sink grease dries out and one of the chips cannot stay cool enough and fails.
Pretty common problem in ALL rear projection sets--if model is 55pp, it is 55 inch set.
You can buy the chips on Ebay for less than 12 dollars---the resistors if needed are cheap parts.
It depends if you are able to do the repair yourself or need to have someone do it for you--most shops get at least 300 for this kind of repair--considering the parts cost less than 20 dollars if you can do it yourself you can save a lot of money.
Any good tech can do this repair in your home in about 1 hour--I know as I have done hundreds of them.
If you need help or advice let me know--I am here to help people.
