Hi Everyone: I'm new to the world of video projectors, and I recently acquired an older model Polaroid E 211 projector. This unit worked fine for a week or so, but now I am seeing substantial distortion: vertical lines across the entire screen (my screen is 50x 80 inches). I have tried all the obvious adjustments in the unit's menu functions, to no avail. I am using a standard RCA-type video in line. This machine is rated for 2000 hours of bulb life, and the counter shows just over 1100 hours. If anyone knows of any simple adjustments to make, or if something is obviously wrong with some component, I would greatly appreciate any input.
