I've had this X-box for about year and 3 months. (I don't really know how long) Now if I turn it on It shows a black screen. It runs just like it should but all you is a black screen and no sound. I bought new cables for it. It I mess with it by cutting it off and on. 1 out of 40 times it will show the X-Box screen and I can play a game. Any I deas on how to fix it with out having to send it back to X-box place?? 😮dd:
