Xbox One not booting up: long black screen and then green screen

I've had this big and apparently unsolvable problem with my Xbox One. Three days ago I tried to turn on the console and it wouldn't boot. Light on, black screen ("no signal" on TV) for about 2-3 minutes and then Green Screen forever, with the three dots
pulsing but nothing happened for hours. I've tried everything, from hard restart to the offline update via USB drive but during the first minutes with black screen the console seems totally blocked, I'm afraid it could be a problem with Hard Drive. I've contacted
the Microsoft support (quite ready and fast in response, I must say) and they told me to send in the console for repairing, and so I did. It's possible that, having left the Xbox One in standby and turned off the electricity two or three times in my house
the last week, something could have gone horribly wrong with the updating process in background. I would just warn people that maybe it's better to keep the console totally off if you have to turn off the main power switch of the house more than once.

Xbox One boot up question

I've noticed that my console does not boot up the same as it used to. Normally when I turned it on the console starts on the Green Screen, then goes briefly to a black screen with the white xbox logo right in the center, and then finally to the dashboard.

Before: Green Screen > Black Screen (w/ xbox logo) > dashboard

Now: Green Screen > Black Screen (NO xbox logo) > dashboard

This sequence is mostly unchanged except that white xbox logo on a black screen is gone. Screen still goes briefly black before the dashboard, but no logo.

I've checked with a friend and he still gets that logo. We're both on OS Version 6.2.13332.0, and power-saver mode.

Is this something I should be concerned about? The console is otherwise functional, but my console got the green screen of death a few months ago, and the same thing more recently. I fixed it both times with the offline factory reset tool but then I noticed
that white logo no longer showed up during the booting sequence.

Any help appreciated.

 

Xbox One Shuts Everything Off at Start up

I am having an issue with my Xbox One shutting off my TV and receiver at start up. Everything turns on initially, but at the black screen (just after the green screen) when the Kinect is booting up with the system, Xbox One shuts down the TV and receiver.
Any advice?

 

Sounds like a failed update. I do CS for Xbox. Try the restore factory defaults option and it will fix that

Thanks but I've tried that too, but it doesn't seem to look for bootable drive even pressing the seek and eject buttons, it's all stucked with the black screen for the first two minutes. Anyway, I've already sent the console to Microsoft, hope it will return
soon, though with the holidays I'll have to wait, probably.
