Hi, I bought a second hand HP VP6315 for an xbox 360. It works perfectly for 15 minutes and then turns from a colour picture to black and white. It has approx 1700 hours left on the bulb and is connected...
DLP projectors use a color wheel to add the color information to a black and white image. If the wheel doesn't work correctly, you get wrong colors or no color at all. I've never worked on one of these, so I don't know if the color wheel is a separately-replaceable part or is part of the lamp module. I haven't been able to locate a service manual or full parts list to check further, but I'll post a follow-up if I find more information.
The usual problem is that the color wheel motor goes bad and it stops spinning, but there could be other electronic problems as well. It could be simply a matter of bad connections that act up after the unit's been running for a while (thermal trouble). You can try researching this model further on the Web to see if anyone can provide detailed parts info, or see if a service shop in your area works on these. And as I said, if I turn up any more information I'll add it.
Good luck, and thanks for using Fixya!
