no picture through HDMI/Xbox wont turn off

So, a couple of days ago I came home and turned my Xbox on. The only problem is that after I turned it on, my TV did not receive any picture. The screen was black. I waited a good 5 minutes incase it was being slow. The xbox didnt make any noise or anything
else so I pressed the power button to turn it off... Well, it didnt turn off. And it will not turn off once being turned on unless I hold the power button down or unplug the console from the power outlet. There is nothing wrong with my HDMI cord. I tried a
different one and the same problem persists. I also tried my Xbox HDMI on a different device and it works. I've had my xbox for years and obviously don't have anything plugged in wrong or anything in that nature. Maybe it's died on me, but I can not find any
information related to my problem. Any help is greatly appreciated.

No picture when connecting Spectrum DCX3200-M box to Xbox One

I'm trying to connect my Spectrum set-top box to my Xbox One but I don't get any picture. The power commands successfully turns the set top box off and on when I go through the wizard to add the cable box to One Guide. I know this
because I see the power turn off/on on the set top box. I just don't see any picture or hear anything. One Guide does load the channel line up successively in the guide. Just no picture. I verified that the HDMI cord is functional. Any clues what I could try?
Thank you.
