Yeh sorry about the images my tablet is pretty bad lol ive sent the cr4 back to where i got it and am looking for an exchange just in case its a fault with the cr4 thank you for the response because i knew that in order for even a an led to light up it needs just the red and black wire (power and ground)Go to your local electronics store (or Amazon.com) and pick up a cheap multimeter, preferable one with the ability to measure resistance as it will help in the long run. Test your red and black wires for some voltage with the xbox plugged in. If you get 0v, then you have a problem with your connections on those two wires. I'd guess your black wire isn't grounded properly, but it's hard to say since the images are really blurry.
