I've had my Mits for about 4 months now and it's worked without a hitch so far. Just a few days ago, I've noticed something. When I have the set on Ant B, which displays the non-HD output of my digital cable, and then I turn it off ... then back on, it comes on in black and white. If I power down in any other input it works fine (powers up in color). The other inputs that I have tested are Ant A (plain cable coming in from the wall bypassing the cable box), DTV (HD cable), DVD, and Aux 480p 1 (Xbox). I've got an extended warranty, so I'll contact the dealer soon. I just wanted to get your impressions first. What do you think could be causing this? Suggestions?
