Xbox One Original Has No HDMI signal

When I turn my Xbox on and there is no signal. I tried holding the power button to fully turn it off, disconnecting the power and letting it sit for a few minutes then powering it in low resolution mode to no success. My next approach was to turn it back on and follow a guide with no signal to get into setting and set it to dvi. This temporarily brought back my signal but it brought me to a screen where it said "preparing console" I left it running on this screen for a few hours but nothing happened. I turned my Xbox off and when rebooting it I'm back at square one. Except now my controller won't connect (even when plugged in) and I can't redo the manual guide to switch it to dvi. Any advice would be hugely appreciated.
