Stupid question. I assume you have the coax from the antenna plugged into the antenna input? There is no issue using cable and OTA on the same Premiere.
Without running guided setup after adding the OTA source, it wouldn't give you OTA channels in your lineup or let you tune them. Guided Setup will fix that. However, the best way would be to hit enter on the channel list in Settings. That way you will not have to redo the setup portion of the cable channels. It will not make a difference but will save you a lot of time.Rainwater, you made me doubt myself, I pulled the rack and looked . Fortunately, I did attach the antenna cable.
Rocko: When I set it up it wasn't attached to an antenna. I set it up on the non-theater TV where there was no antenna cable. I could have answered no antenna at that time. It's been a few weeks, dont' remember. I'll rerun guided setup. Thanks for suggestion.
