Replacing the coolant on a Philips 9P6031 C103 rear projection TV
I am cleaning the "fungus" from the crt coolant on my Philips 9P6031 C103 rear projection TV. It had a very heavy coat of the junk. The concave lens that seals the coolant in the chamber is "etched" on the coolant side. It dries looking like hard water droplets on glass, however it is definitely etched into the surface of the lens and will not wash off. I need a part number for this lens piece and the name of someone that carries the part. I reassembled with new fluid and picture is near new quality. Maybe the etching is not that important. Comments?

the most common cause would be the CRT coolant need replacement in the green and blue CRTs which make the red dominate. Replacing the coolant is the number one cure for that problem. Do not try adjusting the screens as that will only lead to more problems with a phillips. CRT coolant is all thats required.
The CRT coolant change is all mechanical which involves removing the crt and disassembling the coolant chamber so it can be cleaned then reassembled and filled with coolant the phillips CRT coolant kit from www.tvrepairworld.com has the coolant and the instructions for the repair on cd

deflection problem very common on that model. You can get a new LSB board at the following link, leave them a email and they will respond quickly with a price quote for the LSB if they dont have it listed already, they are cheaper than anywhere else for replacement boards for phillips, RCA and GE.

as far as the foggy / blurry appearance goes, you more than lkely have contaminated CRT coolant. This coolant (inside the lenses) should be crystal clear, and normally over time, with heat and time the crt's will grow a sort of bacteria in the coolant. I have drained crt's and the coolant has looked like applesauce before. Once you clean the crt's and replace the coolant with new coolant, the pic should be just as good as new!
What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly. Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps
