BENQ MP622C light tunnel adjustment

Hello guys,

I have a BENQ MP622C and had the same problem with shadow on the right side. I found out that there are two screws for adjusting the position of the mirror. One on the top of the light tunnel and one from the side, when you look from the front, just next to the main lens, see pics below.
It helped me a lot, maybe another 1000-2000 hours of play, hopefuly more....

BenQ MP610 Video Projector Shadow

This model is now out of production. It was sold as one of the bottom end of the "DLP" projectors. It's basically a "good cheap" model using a 1.5cm DLP mirror. And being as such, over the year the "thermal cycling" has most likely caused the alignment to shift. It could have collect some dirt in a quadrant of the lens too. That's possible too. Being a manual focus, there is at least no "auto focus mechanism" to worry about. That can be a pain to adjust. You could fix this yourself with some luck. It either has three screws to adjust or it has an ellipictal ring arraignment and you'll need a two correct size spanner wrenches. If it was in front of me I could tell you right away. In any event, if you turn either one of the screws the wrong way it can get worst or if you don't have the correct spanner wrench to adjust it either you can be more trouble. Plus you need to do this with a light source "on" so you can see the effect. Your best choice in this case is to go to a camera repair shop. One that doesn't send their repairs out if you can. (you have more control over the repair) It's an "adjustment and cleaning" and shouldn't be that expensive to do. Please let me know the results when you decide.

Hi sheridan1,

buy one from an infocus service center. they're under $20 (because it has a 16:9 ratio). but to replace it, you have to remove the top, front, and rear panels. between the lamp and the lens is the colorwheel. carefully remove the 2 screws holding it on and set it aside. the ribbon cable is still attached, so you have limited space. remove the screws holding the tunnel clamp. remove the clamp and the tunnel. replace and reverse instructions. it's part # 306-0095-01
