I have a color flickering problem with my Toshiba DLP 46hm95. It flickers images to different colors. However this only happens in both HDMI ports. there is no flicker through antenna, colorstream HD, or from the dvd player. I ruled out the HDMI cable, as it worked fine for my other tv. Can I rule out the color wheel being the isssue, since it works in the other ports? I have noted a slight dimming recently....will a bulb ready to go out cause this color flicker? The only other option i see is the hdmi from the hd cable box, but I doubt it would be the problem. I wanted to ask the other questions before i go through the hassle of disconnecting cable boxes and checking them.
