Well, that appears to be what has happened to mine anyways...
You see, after playing a match of World of Tanks with a friend of mine, I was starting to experience severe slow-down, so I decided to go to settings to check the network settings. However, it never came up - it wouldn't respond at all. Shortly thereafter, nothing would respond. So, I decided to do a hard reset, since that fixes almost everything. A minute or 2 later, I turned it back on and lo-and-behold, it was even worse. It would show the green start-up screen with the Xbox One logo and 3 loading "dots" but would stay there for what would seem like at least 5 minutes! Usually it only stays for a few seconds. After this lengthy period of loading, the screen would simply go black and do practically nothing. It doesn't start and show the home screen or anything. If I wait long enough, I'll see it auto-sign me in (like another 5+ minutes later) via a pop-up, but nothing else really happens - it's still on the black screen. If I use the Kinect sensor's voice commands, I'll see the on-screen prompts for various things, but will otherwise get nothing. If I tell it to go to a specific game or app, nothing happens. If I tell it to go to settings, I'll get a message telling me to sign into Xbox Live and if that doesn't work, to restart the console (even though I'm already "signed in" - and for the record, I've tried both; neither works). Yep, that's right - restarting the console doesn't work. I can tell the console to shut off, and it does (thankfully), but that doesn't fix the issue. Neither does a hard-reset, surprisingly enough.
I've gone through various support pages to look into this on this site, but I can already tell you that it's not my network, TV, external HDD, or cables. I've already experimented with all of the above via a process of elimination and the only thing that seems to be messed up is the console itself.
I've even tried to send feedback to the Xbox Live team since I'm in the preview program, but that is also non-responsive.
I'm going to continue posting about this in the preview forums and support forums to (hopefully find help), since I have not yet done that yet. In the meantime, if you have any advice that doesn't involve sending the console in for repair (that's a last
resort option, and will probably not be something I do, since the console is new and still under warranty with Wal-Mart), please share it. Also, if you've ever experienced anything like this, I'd appreciate it if you'd share.
For the time being, this is Galactic Geek, signing off of Xbox Live for the foreseeable future. :'(
