My xbox 360 dosent give video
Plug in the Yellow A/V connection to your TV's Video input. or if you have the HD cable you have to have the Green, Blue, Red, pluged in to get video, and then the White and Red for the Audio. (HD cable will not work at all on a A/V input on a TV.) HD cables have 2 red plugs, 1 is for audio, and the other is for video, they should be labeled to tell you what one is what, but if they are not, if you flaten the cords, the Audo White plug will separate the 2 reds, and the one that is between the White and either the Green or Blue plug is the other video.
If thats not it, I couldnt tell you, unless you have a bad connection on the back of your 360, or just a bad xbox.
