Hi, this is my first post to this forum and hopefully not the last. I'm on the floor staff at a 3 month old Carmike 16 plex.I have noticed several things that I was wondering about. First, I have noticed on one auitorium that prints shown in it end up having vertical lines on the film. I haven't noticed this on prints that started in other auditoriums. It's real bad and annoying. What's the problem? Second, another auditorium has a problem with flicker. Is this because of the bulb? Films are always not framed properly in this auditorium either. They're too high. Thank you. ------------------

Tell us everything you can about the booth at your theater. The vertical lines are scratches in the film due to the projectionist misthreading, failing to properly clean the projector or there is something mechanically creating the scratches. Commonly this is the big screen with the "70mm" projector and the extra sets of sprockets confuses some projectionists.The flicker could be caused by the bulb, perhaps there is an open diode in the rectifier, lots of things. As to the framing, there is a control generally labeled "frame" that the projectionist can turn slightly in one direction or the other to properly center the image vertically. If it is not centered horizontally, then this is an entirely different problem. Let us know make, models, anything you can about your booth and we'll help ya as best we can.
