Anybody else have this common LCD HDTV? I have tried everything and I can't figure out how to get it in regular TV mode. I see a selection for DTV/Cable, and select that and turn the Dreamcast on, but I get no video signal to the set.

I am SURE at least somebody else here has one of these tv's, so could somebody please help me out here. I have already looked through the book and found nothing about regular TV mode.
