I just picked up an InFocus Litepro 570 for free because it doesn't work. The person didn't know the exact cause of it's death, but I figured it's worth a shot to see if I can fix it. Unfortunately, it's proving to be a little more complicated than I thought, since I can't even get it open! Is there anyone on here that somehow miraculously has a service manual that I can either a) get for free (pdf form) or b) purchase? Any help would be appreciated.. even if you know what kind of screws they are..
