I had the exact same problem and the fix is easy to do. Unplug the TV first of all and wheel it out so you can easily get to all of the rear screws.

1. Remove the screws from the ventilated back panel (the piece of wood with a bunch of holes in it surrounding the AV connection panel.
   
2. Remove the wood panel you just unscrewed.
3. Remove all screws from the upper plastic case on the back.
4. Remove the back plastic case carefully. This is a little tricky due to two metal pins that it hangs on. Lift it upwards and you should be able to free it from these pins
5. At this point you should be able to see the entire workings of the TV, and consequently the massive amount of dust that has accumulated.
6. Carefully take a vacuum and remove all the cobwebs, taking care not to bump the mirror or the lenses.
7. First, I used some compressed air to clean off the lenses and then used a clean microfiber towel to remove all the dust from the lenses, the mirror, and the screen on the inside. Make sure the part you are wiping the mirror and lenses off with is free from any dust or dirt or you will risk scratching them.
8. Reverse the dissasembly process to put the case back together.
9. I went through the convergance settings at this point and found that they were all out of calibration and as such recalibrated them. Use the mulitpoint calibration for best results.
10. Enjoy a much cleaner brighter TV!
    

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.
