Debbie has always had channels 2-13 with an antenna. After a brief stay in the hospital, she came back and didn't get any channels at all. Leo suspects that while she was convalescing, the FCC moved the broadcast frequencies for all the local channels. It doesn't change the channel number, mind you, but what Debbie needs to do is rescan her TV to re-acquire them. Go into the TV menu and look for scan channels. The TV will then rescan the frequency range and re-acquire them.
