Question about Philips 43P8341 43" Rear Projection Television
Go into your menu there should be something called convergence in the menu a red and a blue convergence. when you select one you will get a cross in the center of your screen use the selection keys to move this so the two crosses are on top of each other. once you align both the red and blue ( the green is the base) then go to the multi point convergence if all crosses are lined up you are good if not then you will need to replace the convergence I.C. for that color or both. let me know how this turns out.

Your TV most likely has one or more possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and I have green outlines in the pictures - 2c07611.pngeplaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
