I have a Domino 30 projector with 900 hours. It had worked great up until now. After an hour or so the image will freeze and be in black and white pixels. I have trouble shot my connections (connected the projector directly to the direct tv box and it still froze... even froze with DVDs). I am not sure what is causing this and I will attach a picture. Thanks for your help.

Does the noise (sound) of the projector change when this happens? I wonder if the color wheel is going bad. Also what inputs are you using?

Thanks!
