How do i hook up the color chords from my xbox360 to a sony flat screen?

Put it like this.yellow isz used for the screen to show.white is the main sound.red is kinda secondary sound.so if u dont have a white cord.u need to get a new one or complain to sony about what kinda tv doesnt have the yellow output(video i shulda said)anyways.put the yellow in the yellow.red in the red.white in the white.make sure they r in the same rows.if they r not maybe thats the tv or u jus have em mixed up.then switch the output.kinda like.im not sure how to explain this.srry.i tried the best i could tho.
