Repairing the BenQ™ PE7700 DLP™ Projector

While this projector had much trouble with premature lamp failure initially, BenQ did eventually get the issue resolved with a firmware update which apparently changed the fan speed. Despite it's issues, the projector had superior picture and user interface to anything else in the same price range at the time of it's original release.

I have created two repair guides based on repairs I have made to my own PE7700 projector. The first guide walks you through disassembling the projector to remove and replace the fans. The second guide is designed to help you re-assemble a completely disassembled pe7700, including which screws go where for each part or sub-assembly. I am hoping these guides will help you to repair different areas of your projector. These pages are still a work in progress so I am sure there are typos, spelling errors and missing information. I am working on getting these pages finished, if you have any suggestions, corrections or questions you can email me: david at functionalchaos dot net.
