I have a ViewSonic PJ506D DLP Projector. This projector is connected to a DVD, a PS3 and a Wii through video components cable. The lamp has about 316 hours, of a rated 3000 hours. Today, the whites started to flicker really bad, kind of like doing S on the screen, similar to when you film a fluorescent tube with a camcorder, i don't know if i'm being clear. The darker the colors, the less flicker/Sing/dancing of the image. I have done no "maintenance routine for the projector", cause i don't know of any for it. Should i clean it or something? The PJ50D is hanging on the roof upside down. So, even if i'm on warranty, i wanted to know what the thoughts of you people are.
