Question about Philips 60P8341 60" Rear Projection Television
Going to change coolant in red crt hoping it will get rid of squiggly line. cleaned all three screens and reflector or whatever it is called. didn't get rid of line. suspect green crt "c" lense.
Sounds like you may have just left one of the wires loose from the red tube. Not likely an issue from the gren tube but you can always cover the top of the lens and let just green shine up. That may help narrow it down also.
Here is more detailed info for you also.....
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 TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

I will say that you probably still have the clear liquid (Glycol) still on the board. I recommend cleaning with a degreaser spray and brush it off with a clean 1inch paint brush. You can get the spray at Radio Shack The glycol is hard to remove and is conductive to electricity.

You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu.
Screen is bowed in but stationary.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

The coolant in between the CRT face and the focus lens has probably become discolored and would need to be drained, cleaned and refilled. The green CRT is the center one and it would have to be romoved in order to refill it.
