Well, last night during a screening of "The Mummy" I paused the playback and took a close look at the screen, then blanked the picture to its default blue and black screens to check for pixel problems. Like "tk" mentioned, the spots I'm seeing aren't quite full pixels and some are the cyan color, others are like green streaks, very ill defined. Even a weird red streak on one. Right next to the screen I can clearly make out individual pixels (alas, with LCDs, pixels can be evident half the room away!) and none of the center "specks" are full pixel size nor are they a distinct square shape. There are two full-size, full cyan square "dead" pixels in the very bottom left corner edges, but I'm not concerned about these because they're even beyond the typical scan of 4:3 material.
I'm wondering if it's dust I'm seeing, but I would think dust in front of the light path would block light and render itself as dark grey or black on the screen. Do LCD projectors truly have 3 panels, one for each primary color? Do these then get combined on a different panel before projection? This might explain the different colors I'm seeing, depending on which color panel has the defect/ dust.
Living at higher altitudes than most other places might explain why some of my optics (cameras, scanners, binoculars, etc.) manuf. in lower elevations can get dust "sucked" up into them when shipped here. I wonder if this is what's happened to my projector and maybe there's a way to get the crud out of the light path w/o voiding my warranty.
Any more light shed on this problem http://www.avsforum.com/ubb/wink.gif
would be greatly appreciated,
