Instructions
Turn around the television and NES, so you can see the back panels of both. You will notice a set of red and yellow cable inputs on the back of the NES and a set of red, yellow and white cable inputs on the back of the TV. The NES only outputs sound in one channel, so you will not use the white cable input on the TV.
Plug the NES power cable into a wall outlet.
Connect the red and yellow cables that came with your NES to the red and yellow inputs on the back of the system.
Connect the other ends of the cables to the red and yellow inputs on the back of the TV.
