If your TV has composite video inputs, use the A/V cable that came with the player. Connect the black mini-plug to the AV out on the left side of the DVD player. The other side has standard composite video (RCA jacks); connect the yellow plug to a composite video in jack on the TV. Then plug the red and white plugs to the matching Audio in for that composite video connection. If you do not have the adapter, get a replacement like:

If your TV doesn't have composite video inputs, you will need the appropriate converter depending on the TV. Most likely you would need a composite video to RF converter (an RF modulator) like this:

I hope this helps.

(If you have enough devices that you need a switch, you can find them in stores like Radio Shack. If you want to convert to component video, those converters also exist. However, each converter will degrade the signal a bit.)
