I have an old Sharp XG-E1200U PJ which I bought second hand. Apparently the first owner wasn't took keen on cleanliness (think Pig Pen, Charlie Brown's friend). The problem is that I can't find a good way to get to the optics to clean them. I've had the case open, lens removed, and even removed the main circuit board, and it still looks like I need to completely disassemble the thing to get to the panels. Am I missing something here? (Is this why the say "No user serviceable parts inside"?)

Also, is there a way to distinguish dust on the internal optics (LCD Panels, mirrors, prisms, etc. ) from dust on the lenses? This is kind of similar to an earlier post on this forum.

Any/all help is greatly appreciated.

OK, the responses are overwhelming. I guess DIY ends for most folks at the outer casing of the projector. ;)

Any thoughts on the "where's the dust" question. Yesterday I adjusted the zoom until the dust came in perfectly focused - projecting a white source, the particles were all Red. Looked like my red LCD had exploded and deposited little fragments quite uniformly across the picture. :eek: This couldn't be the case, right? Maybe it's just dust somewhere along the light path leading to/from the Red LCD?
