I was wondering about access to various models to enable the cleaning of the optics and lcd panels. This has been a major bug-bearer of mine since my interest in projectors back in 98. As the pj does a great job at immitating a hoover to regulate temp and even if not in use, the optics and panel still accumulate atmospheric grime. Cleaninig is paramount to maintaining image integrity. The problem is cost, around £200 just for my humble Hopper. My first lcd pj was a seleco model, a big brute, short lamp life ect, but the access to clean the thing was so easy. There was no impedance to the lcd panels, whereas the SV10 was and is and absolute pig to gain access to the panels and prism. Now, has anyone tried to attempt cleaning the A-100, actually getting to the panels. Any info on any current models and their internal accessibility for cleaning would be appreciated. And how are the dlp's cleaned?
