Question about BenQ W500 Projector
Most projectors have a safety interlock switch installed on the lamphouse door and in the filter cavity. They are there to keep the unit from operating if one or the other aren't present. I'm not familiar with your exact model, but I've seen the lamphouse interlock switch in several Panasonic units come-loose, and slide to the point where the pin on the door doesn't push the switch any more. I would suggest looking around your filter for such a switch. The one in the Panasonic is behind a round hole, and is 'pressed' by a plastic pin on the door. Your filter may be similar. Hope it helps. :)
