Question about HP vp6320 Multimedia Projector
The menus always look correct. Video images from composite or VGA connection look good for the first few minutes then rapidly decay. First there is a quantizing of shades. (it looks like computer screen in 16 color mode - there are "relief map" like gradations on the image.) Then eventually, after 3 or 4 minutes, the image loses most color info. It looks like a tv with the color turned low and the tint all mixed up. Faces are purple, most of the image is monochromatic. The lamp has only 475 hours on it. It worked fine for months then the "relief map thing" slowly appeared. At first I thought it was a bad video signal, but then it got increasingly worse. Any info would be appreciated.
The probelm is caused by either a bad color wheel sensor, color wheel or formatter board. I have the new redesigned sensor assembly and color wheels that I can sell. It is best if you send me the projector for proper diagnosis.
