HD Not Working Correctly

So i was hooking up my new 360 today, i used the composite av/hd cable that came with my premium console. I plugged it into the 360 and the corresponding ports in the back of the TV, flicked the switch from 'TV' to 'HD' and turned on the console. The picture was different shades of green (like a black and white screen except green) and no sound was being played.

Anything extra i need or something im doing wrong?

P.S. i tried the console at 480p, 720p and 1080p all giving the same result.

Sounds like you're hooked into the composite jacks (Yellow for video, Red and White for Sound), you need to be hooked into Component Jacks (Often Green, Red, and Blue...all of which are used for Video)
