Panasonic model tc-l37u22. Can't get 1 channel. Seems frozen on a comercial. 2 green squares about 1 in

What kind of a tv are you using and who is your cable or satellite provider?
I would unplug both tv and cable box for 10 seconds and plug it backin. This will reset both your tv and cable box.Then do a channel search.Let me know if this works.
