Suddenly lost HDMI connection but now won’t turn on. Completely dead.

*NOTE: Xbox literally ran 24/7 for months and months whether played or not … constantly hot and dusty, rarely cleaned but did so with compressed air.(Obvs it belongs to a teenager so you’re preaching to the choir my friend)

During play, HDMI connection to the TV suddenly went out. Noticing the HDMI cord was still lit at the TV and console connections, Xbox was manually powered down, unplugged from the wall, briefly air dusted and set aside to cool. Well, turning it off must have totally killed it cause it’s DRT-dead right there. It doesn’t do a thing. The only thing that still has any life left is the controller but that doesn’t do jack for the console.
