Sorry to hear that your viewing experience has been interrupted. I would, right off the bat, attribute this to a faulty colowheel. Before I jump to aimless trouble shooting, could you refresh my memory with what model projector you have (If I remember correctly this was a projector..)? Also if you could explain a little bit in detail any and every malfunction that happens as you power the unit on.
My apologies I am very active in this forum and I loose track of my posts, but I hardly ever forget people!
