it is most likely a burned polarizing filter. There is a polarizing filter on the blue light channel and another on the red channel. When black, or other dark colours are displayed, the red polarizing filter is supposed to block ALL of the red light being projecter. If the filter is burned, some light slips through and creates a red tinge on the projected image. If the red tinge only appears on dark images, but is absent when the images is completely white, a damaged filter is likely the problem.

Seems its hard to buy them. Best bet is probably buying a broken projector from ebay and stealing the filters out of it.

three green lights come on then the standby light goes red and remains on when the projector is plugged in. The lamp and fan do not come on when the power button is pressed instead the lamp light comes on red.

no, it is the light filter (polarizer). it is caused by excessive heat and dust buildup. blow out projector with canned air to prevent further discoloration, but the filter needs replacing.

maybe its your projector lens check it out..moist or something..

the filter lense of color red had discolored

This would appear to be a componeent failing and I doubt if it is user fixable.
If it unser warranty send it back whence it came,

What do you mean by red filter? There is no red filter in this unit.

Hi there

Have you tried another cable ?

It sounds like it is related to the red filtered glass before the prism inside the projector. When this gets to hot, it will burn a spot on the glass that causes the yellow spot. I have seen in happen on alot of epson 53c projectors. This has a red filter that is easily scratched when it gets too hot. It will actually look burnt.
