What you can do is that you send your console over to Micro$oft. That's right, Micro$oft has some kind of repair service to fix your Xbox 360 green screen error, but it's obvious that it's not for free. Micro$oft is Micro$oft
So what did they come up with? You send your console over to them, wait 1-8 weeks, and on top of that... You will have to pay $150 if your warranty has been expired
.Or you do it yourself, it's the exact same repair as the red light of dead.
