Question about Philips 51PW9363 51" Rear Projection HDTV-Ready Television
Your symptoms sounds like a damaged convergence IC’s.
There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.
Most of the time you can just correct the convergence through the television menu. All that needs to be done is line up the blue and red to the green. If the colors do not move then there may be faulty components in the convergence circuit.
If your colors line up in the middle of the set and at the top but the picture is concave then you may have a faulty component in the pincushion circuit. When this circuit fails the picture will have an hourglass shape to it with black in the middle on the sides, or you will see square objects as hourglass shapes.
You may want to consult a Television Repair Technician, or repair this yourself. If you want to tackle this yourself, let me know, I can give you some direction for the repair
I hope this information allows you to resolve this issue.

Here are some of the most common symptoms and examples of a convergence problem.
This is a very common failure on Projection TV sets.
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 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 tI am getting double vision in top and bottom - 47a7bc4.pngonvergence 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 or you can call in a pro.
If you want to do the repair yourself check the site www.TvRepairKits.com.
Their kits include a step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
