I just got my zenith dtt901 out of storage, hooked it up to the tv, tried both RF and RCA connections, am sure I did everything right (I have dtt900 that I am currently using, so just copied the connections). The box turns on but on the tv I get only snow or the blue screen (depending on whether I set to video or channel 3 or 4). I know the box is reacting to the remote cause the blue light blinks when I change channels on the remote. But it seems that no antenna signal is being passed to the tv. I had used the box for only a few weeks over a year ago and it was fine. Is there something I might be missing? I can't get a menu to show up on the tv at all, so can't change any settings in the box. Why would it just die when not being used? Thanks for any ideas.
