I'm having a similar problem, I own an original Xbox one and recently I was playing Skyrim (a few days ago) when my mods started acting up. I reset the game then I reset my console and I haven't been able to turn it back on. This isn't the first time it's happened a while back I was playing a game when I turned it off and left for work when I got home it wouldn't turn on and it stayed like that for a week till one day it magically turned back on. I've read that there's a feature in the settings that will make the console think it's always on even when it's off and so because of that it will keep it from turning on I believe it's the “Always On” option however I have been unable to turn my Xbox on for a few days now to even confirm that
