My Xbox One X (Scorpio Edition) gave up the ghost at some point two weeks ago, I think the video element in it failed. It boots but never sends a real video signal to the TV... the TV can tell somethings plugged into it, but nothing ever comes through and it stays in an error state.
Repairing it looks really difficult, requiring soldering and a lot of effort, and unfortunately a repair from Microsoft is $250 which sucks... ALmost the cost of a new console.
I had issues with about a year ago and I honestly should have sent it back then. It would run incredibly hot when playing 4K/HDR, first noticed it with the new Tomb Raider, and I thought maybe it was Tomb Raider, like a buggy game. When it would get super hot the game would perform poorly, audio would cut out and scramble, and then my controller would disconnect, and then reconnect. Then I didn't notice it for a while but it started up again with Red Dead Redemption II. By now it was already well past my warranty period. For the most part I'd keep it running alright by just keeping play sessions to an hour or so, which fit my lifestyle anyway. Then, it happened with Sea of Thieves and I knew it was a problem with the machine. Finally, I was away on vacation came back to power it up and play Bloodstained, and it seemed dead... no video, I think the video unit, the video card to the HDMI port, burned out or something.
Microsoft has been pretty unhelpful throughout all of this, and the $250 or $275 repair fee is just too much to ask, especially if it doesn't fix the problem.
