Question about Philips 55PP9363 55" Rear Projection HDTV-Ready Television
LOOK at attached photos and if they look anything like yours you have a convergence problem.
Most of the Philips sets use either 2 of the STK-392-120 OR a few use the STK-392-110 (NOT INTERCHANGEABLE PARTS).
WITH SET unplugged and back cover removed they will be on far left board on side by side metal plates with fins (heat sinks).
Set will need to have chassis in "service position" to replace them and I can tell you how.
TOTAL PARTS COST IF PURCHASED ON EBAY will be under 25 dollars total.
If the photos or this information helped you rate this solution as very helpful as I do this here for free.
I can assist you with this repair and most can do it themselves.

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.
Common Symptoms include....
Here is a quick test....
Using your original remote go-to the settings menu then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move RED and BLUE in all directions - up, down, left, and right.
If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.
Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
