Question about InFocus ScreenPlay 4805 Multimedia Projector
We found the problem after a shift of venue. The projector was taken down from its mounting, stored and then put up in the new place. It was also mounted when building alterations were happening and then cleaned out with compressed air.

I had a similar problem with my InFocus LP600 although my black stripe was straight up and down. I am guessing this is caused when the unit is bumped or dropped. This is not an easy fix unless you have a lot of experience with small tools and parts and you may need an extra set of hands. I found some tiny alignment screws under the lamp cover and hidden beneath a peel-off 0.5" x 2" black plastic strip. The screws are located between the bulb assembly and the main projection lens and are oriented 90 degrees apart around the light projection path. The trick is in getting the projector to temporarily function with the lamp cover off -- it has an interlock tab on one edge that pushes on a microswitch when closed. We turned the projector upside down but raised on some slats for heat dissipation, gently held the interlock switch in with a small screw driver, and plugged in the power cord. After pushing the power switch to get the image, I adjusted the tiny screw that is angled towards the front of the projector and the stripe dissapeared! Since your stripe is angled, you may need to adjust both alignment screws. The screw heads are very tiny torx bit types but I was able to use a 3/64" (.05") allen (hex) wrench that came in a set of cheap jewelers type tools that are widely available. Be very careful while operating the unit with the lamp cover off as there are very hot surfaces and exposed wiring.

SOURCE: upside down images
the projector will project 4 image configurations: front, rear, ceiling front, and ceiling rear. go into the menu, under settings, and change it from ceiling to front.
