Many new televisions no longer come with a coaxial cable connection port. This is because most electronic devices no longer use the lower-quality cable hook up. However, if you are using a lower tier cable package that does not use a cable receiver, you need to take the coaxial cable hook up and convert it into an RCA (composite) cable connection.

Attach the coaxial cable into the coaxial cable connection port on the converter.
Hand tighten the cable into place. This secures the connection of the cable, preventing it from becoming disconnected while in use.
Plug the RCA audio cables into the RCA connection ports on the converter. Insert the other ends of the cables into the "Video" port on the TV.
Power on the television, press "Input" on the TV's remote control, then select "Video" and the cable programming appears on the television set.
