On your TV, have you gone into setup (or "system" on some TV's) and set it up to receive cable? All TV's are different, but some need to be told to receive cable. Then you need to set it to "auto program" or "auto scan" so that it will receive all the available cable TV channels. Did it come with a manual, or do you have the ability to go online and look up the manual?
Hey, don't worry about NASCAR . . . they'll just be making left turns.
I couldn't resist.
