Facing TV Problems? Ask a TV Technician.
It could be you scanned Antenna Digital TV and not Cable Digital TV. Antenna goes up to 69, and Cable goes up to 135. That model number is ***** your serial number for that TV, it should look like 50PCxxxx-uA.aaaaaa... X= numbers A=letters.
If you Autoscan, see if your model makes you select your choice of what you scan for, or if it goes through ALL the choices by itself.
