Question about Philips 60P8341 60" Rear Projection Television
My dad just gave me a Philips 60P8341 60 in. Rear Projection TV.
He said it worked fine at his house,He just upgraded to a LCD TV.
From the move, in the back of the pick up,across town.
I got it all hooked up,but now there is a glowing brightness around all white or light colors.
I suspect dust got moved around on the lenses.
I read in these posts,it may be dirty lenses.
I am pretty mechanically inclined,but have never seen the inside of one of these TV's.
What is the process of opening up the TV,and getting to the lenses and cleaning them.
I read use camara lense cleaner or mild dish soap,and lense cloth.
Pictures would be helpfull too.

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 should be replaced. 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.
