If no one answers on that model TV (so many models), see following: All the digital TV's have a "search channels" function from a menu button either on remote or on front of TV. See if menu has something like "Setup" and "Auto Tuning" (or words like that) which indicates a digital TV, if no channel search likely analog TV. Once clicking to search for channels (arrow buttons to get there and enter button to start, or some other buttons I saw once did that), it scans the airwaves starting with Ch2 and ending with ch 78 or so. Takes about 30 seconds for it to find channels with antenna connected. Antenna can be old UHF antenna. Search completed, the TV can show the channels in normal channel viewing. If not a digital TV, you can get a DTV converter box to get free tv off the air, it is basically a digital TV tuner that works on analog TV's. You can get those on Ebay.
