Green and blue faded


Some of these had bad picture tubes--(model indicated here uses 3 tubes)

Simple test is go to a black and white channel and turn color to zero= is the screen black and white or some other color?

Also go to a unused video input and look at screen=all you should see is black screen with the input number in green= any other color and something may just need to be adjusted.

Pioneer Elite Pro rear projection 620HD - Picture is still there but brightness and "white" have faded over years allowing for mediocre viewing when room is dark only. During the daylight picture is visible if viewed straight on and within 15 feet from set. Any suggestions?

The only thing I can think of that would make the picture fade to black is a loose solder joint on the filament supply. Each of the 3 picture tubes has a filament and if the 6.3 volt supply to those filaments is suddenly lost, the picture fades to black as the filaments cool down. An experienced tech can find and correct this for you quite easily.
