Question about Philips 55PW9363 55" Rear Projection HDTV-Ready Television
I've had my 55PW9363 Phillips TV for about 3 years now, and for the past 6 months the picture has been horrible.
I decided today to take the front cover off and clean it, as the mirror and lens' all had a thick layer of dust on them.
After a good thorough cleaning, I think I discovered why the picture has never looked right.
There is no picture coming out of the blue tube. Just blue light.
The red is crystal clear, the green has some spotting under the lens, and the blue is just blue light that changes brightness along with the other tubes.
When I mess around with the focus on the blue bulb, I can see what appears to be shadows moving around, but again... no focused picture what so ever.
I'm fairly confident repairing the TV myself, but I know nothing of TVs. I don't know what parts affect what, what parts to ask for, etc.
Any help is greatly appreciated,
Phillips have been known for the coolant to get contaminated especially in the blue CRT. it congeals and your picture will become hazy and out of focus.This is something you an do yourself. If youre careful. If you would like instructions on how to do this proceedure. Let me know.

A few tests to do:
In the user menu turn the Color level to zero. You should see a nice B&W picture, shades of gray only, no red grn or blu tinting.
Take the screen assembly off and look down into the blu tube (Tv On). Do you see any cloudy fluid or stuff growing on the inside surfaces of the blu tube?
thats a classic problem of bad fluid
Changing the coolant in the blue crt fixed my problem.
