Things You'll Need
Instructions
Connect the single-plug end of the composite cable into the Sega Genesis' A/V out port, on the back of the console.
Connect the yellow composite plug into your television's yellow input. On some TVs, this input is labeled "Video." Then plug the white composite plug into the white input next to the yellow input. This input may be labeled "Audio."
Tune the television to the correct input channel and then turn on your Sega Genesis. You should see a blue Sega logo.
