My Xbox will turn on and will display nothing on the t.v. I've tried unplugging the power cords for 15-30 minutes and still nothing. I've tried switching HDMI cables and still nothing. I've tried turning it off by holding the power button for at least 10 seconds. I've tried everything and I still don't know what is wrong. The controller won't connect to it, nor would Smartglass even when the xbox is on. I've made sure the HDMI cables are in the correct slot. All my xbox is good for is turning on and nothing else. The t.v is in the correct settings for the xbox because I've been using this t.v for my xbox ever since I got it, and it's been a year since i've owned my xbox one. I've been at this for 2 days power resetting and doing everything and yet this is no solution. I need help!
