Hello. I have a very annoying problem that has been there since i bought my PJ, now it has 793 hours on it and the problem starts to get on my nerves. When i watch a movie, usually bluray movies, and theres vertical line in the picture. fx. a white curtain with black vertical stripes on it, and the camera pans across the room, theres a annoying flicker on the curtain. Is this normal with LCD projectors ? I think i have noticed it on a lcd tv once. Hope you guys can help.
