Guitar hero II controller doesnt play

For the 3 other users with the same problem, your problem can be solved by playing on a different Television or hooking up a VCR or DVD player to your TV and putting your xbox 360 into it. Or maybe your AV cables are just broken, On the AV cables there is a Yellow Wire, a Red Wire, and a White wire... All three have to be plugged in to recieve full sound.

Try setting the sound in options to mono instead of stereo.
