I've noticed a defect in my library's projection screen. When images are projected onto the screen, there are four small rectangles running vertically in the middle of the screen which appear much lighter than all other parts of the screen. These rectangles can also be seen on the screen with the projector off when looking up close. The screen is stored in a mechanical assembly in the ceiling, so I'm wondering if the screen is rubbing or sitting on parts of that assembly. Has anyone seen this sort of problem? Is it something that can be repaired or fixed? Thanks.
Michael May Carnegie-Stout Public Library, Dubuque VIDEOLIB is intended to encourage the broad and lively discussion of issues relating to the selection, evaluation, acquisition,bibliographic control, preservation, and use of current and evolving video formats in libraries and related institutions. It is hoped that the list will serve as an effective working tool for video librarians, as well as a channel of communication between libraries,educational institutions, and video producers and distributors.
