Ok so I traded my friend for an Xbox 360. It is the really old one and the night I got it it got the one red light with an e74 error. I took it back to him and he fixed it then 3 days later it did the same thing. He told me that the AV cable is really jacked up and you have to hold it in a certain position for it to work. I was wondering if the problem is internal or could it be the AV cable? PLEASE HELP!!
