Lost power while playing a DVD. When powered up again (within a couple of minutes) I had horizontal banding (flickering) and the black and white "stippled" band at top of screen as indicated in image. (By the way, the image was projected on the cinder block wall in my basement workbench, so please ignore rectangular blocks :) Upon inspection it appears that the color wheel is not moving, but I am not completely sure if that is true. Any ideas about the problem? I'm pretty good at fixing electronics, are parts available and is this worth fixing or selling for parts? The lamp has about 800 hours. Thanks, da Menace
