Okay, I'm in a new apartment, the landlord says the cable service is on, I don't have a cable box or cable remote, so I assume its analog, how do I make sure my TV is set up to detect the channels? I reset the factory default thinking that would help, but that just gave me a screen saying "No input signal sources could be located. Please check cable or antenna connections." And now I can't get away from this screen to even play Xbox or anything. Any help would be much appreciated.
