I'm having problems with my daughters Xbox One,the green logo comes up when its switched on but then the screen goes black. I have tried power cycling it but to no avail. I have noticed though that if the power brick is unplugged from the console the light goes orange, but when I plug it back in it goes white as though the Xbox is on but the front light does not come on. Its not set to Instant on mode so that cant be the problem and I have tried it on my power brick but the same thing happens. The console is not in the Preview Programme so it cant be that either.
I'm in the process of downloading the Zip file to try and update it offline to see if that helps. Is this likely to fix it or will I have to send the console off for repair as its still under warranty.
Any help greatly appreciated
