My jvc 27" tv was so dark I could hardly see any night scenes, even with the bright all the way on. If you push the sleep button, let go, then hold down the video and display (together), the service menu will come on. Scroll down to #7 (too dark) and adjust the brightness there. Works immediately. Good luck.

It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.
there are 2 mirrors did you clean both there is one down in front near the light source when front screen removed lean in and look down there is another smaller mirrorclean it
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.
i had a similar problem and it ended up being the bulb. The indicator light never lit up but after i replaced th bulb I checked to see how many hours where on the bulb and it was over 8100. they state the bulbs are only good for 6000. when i replaced it ($140 on ebay) everything was fine.
