Green Screen of Death here. I get home, have the console and five games waiting for me, plug it all in, start it and I never saw anything besides the logo screen. Turned to black after some minutes, then just didn't do shit anymore. Second boot same thing, let it sit there for half an hour, nothing. Third reboot: No more green screens, just black void, sometimes flickering.
Spent one hour on the phone waiting for support, talked to them, got to know how you delete the system cache on X1 (hold power button for ten seconds to turn it off) and then got told to return it where I bought it (impossible, they don't have any systems left) or start a repair ticket. Takes 2 to 3 weeks til they send my console back. Yay! Wanna know what the worst part of it is? I experienced the same shit with my original Xbox. Bought it day one, mainboard broken, waited three weeks for a replacement. Had RRODs and DVD drive failures on various 360s.
I honestly don't know what I'm gonna do now. Might even turn to the dark side and go PS4 only. I am just annoyed by this big useless black box that's much louder than I anticipated, quiet it is not. But the controller is beautiful.
