Hey Fellas,

I've got an HP XB31 DLP Projector from about 2002. It was working fine, until one day the image got a little screwy. When I turn it on, the color wheel still spins and the lamp is fine - but the screen alternates between hues of green and blue all down the screen in equal intervals. I can still see and read the HP logo and the "searching for signal" text at the bottom, but it's just far out of proper color. One of the segments is white with black pixels randomly in it.

I'm not that great with DLP terminology...but I took out the DLP chip and the little piece that actually reflects the image onto the lens, and I can see the small "hp" logo and the strange white/black segment on the part - so I think the DLP engine is sending it a bad signal or something. If yall might happen to know how or if this can be fixed, i'd appreciate it - and if anyone has a broken projector like this one at home I could buy off of you to fix mine, I'd appreciate that as well.


This is my first post here - I just bought a Samsung 750 series 67" TV, so I'll be learning the in's and out's of DLP once that arrives (even though I don't believe that has a traditional color wheel).

Here are some actual images of what it's doing. The first one is just the image when I turn it on, the second is when I adjust the keystone. You can see the segments and the white strip.
