A slingbox doesn't play on a TV. It can however pass a signal though to the TV from your conencted component (such as a cable box or satellite box).
The out put of the cable box or satellite receiver connectes to an "input" on the slingbox. The matching output of the slingbox gets conencted to the TV's compatible input. this is a "pass-thru" connection. The TV would need to be put on the input matching the connection made on it's jack panel.
