Did you try both "Cable" or "Antenna" in the ANT In box?
Also, if this fails you can research external tuners. You see these on Amazon and maybe in Wlamart stores.
I've had a Mohu Sky 60 antenna since 2013 but never hooked it up. Working on it now & was able to get some channels with it on small TV but when I connect it the same way to 50" Panasonic TV (TC-P50C2) I get no channels. Doesn't matter where I move the antenna, 0 channels. Yes, when I move antenna, I rescan. Help!!!
