My Xbox One (when in energy saving mode) fails to start up. I press the start button on the console, it lights up for 3-4 seconds (the TV registers an incoming signal but no picture appears yet) and then it just stops (TV looses the signal and the backlight on the console button turns off). I have tried several time to turn it on (sometimes with a short press and sometimes with a long press, sometimes unplugged the console, etc.) and after several attempts it comes back to life. But I cannot figure out what makes the trick. When in Instant on mode, the console powers up without a problem (using my voice). Any suggestions what may cause this issue?
PS: I am using a US model in a European country (in case you think it might be related to voltage).
