Two months ago, I traded my Xbox One for a preowned One X and starting last month, the screen has been randomly flickering, even on the main screen. Gamestop stop helped me diagnose it as a broken connection in the system. Since I bought a warranty, they let me trade it in for a brand new one, and that was three days ago. I just found it doing it again today and now I'm a little irritated. Is this a common problem?
