Xbox One signal problem

So last night I went to turn my Xbox on. As it was signing in i accidentally back out. So i just go to sign in like normally, but then it started to take longer than usual. After about a minute or two i decide to restart the console figuring that will help. But then it tells me there is no signal and to check the source and see if power is plugged in. The console works i can hear the fan start up i can eject and load game discs. There is just no sound or picture. Today i tried three different tvs and three different HDMI cables none if them work. It just stays on as well i have to press and hold the power to turn it off not just a quick push. Any help will be appreciated
