Xbox One X Shut Itself Down

Hello all,

A little under a week ago, I posted
this thread regarding the fan noise on my Xbox One X, and how it seemed to be louder. My overall concern of course being that my console is acting up and may conk out soon.

A few more oddities have cropped up since that thread:

- I've noticed _Halo: The Master Chief Collection_ acting finicky lately. A few days ago when I went into "Career" to look at some new unlocks, that section simply would not load up and would be an empty menu. I could hear the sounds of the cursor moving
around, but was unable to access or do anything other than bow out.

- A few hours ago, I was loading up a Campaign save in _Halo: The Master Chief Collection_, and midway through loading the audio glitched up and my console shut itself off! The console had not been on for too long either, I think maybe half an hour or so,
and I hadn't been playing any games up to this point. I checked the back vent of the console and it didn't feel overly hot to me either.

- Today I tried to watch a Game Capture video I had uploaded to my Activity Feed, and each time a tried, the video would conk out and cut to black after several seconds (the time would vary a bit).

- While I was testing today, I noticed that during boot up and the green "Xbox" splash screen, my TV will now display an error message for a few seconds towards the end of the boot up sequence; something along the lines of "Unknown Signal" or "Invalid Signal."
I have my Xbox One X set to turn on my TV, and I rarely have my TV on in advance. It's possible it has something to do with it attempting to turn the TV on, but it's odd as I have not seen this before. Note my console is also set to "Energy Efficient."

- Possibly unrelated, but _Mortal Kombat XL_ has often had issues launching, both when I was playing via Xbox Game Pass Ultimate, and now when I've purchased it. Often the game will launch to it's initial splash screen and then make a chime and drop back
to Home. It can take a few, and sometimes over half a dozen, attempts for the game to successfully launch. This is the only game that does this, and I have clean installed it in an attempt to resolve, as well as cleared my system's cache, with no luck.
It's possible this one is game-specific though and not related to my other issues.

I did have an internet outage yesterday, and spent some time playing both _Halo: The Master Chief Collection_ and _Mortal Kombat XL_ offline. My services are all back up and running fine today. For _Halo_, when I fired the game up it asked me if I wanted
to use the save from the console or the cloud, and of course I chose the console. It's possible, I supposed that something went funky there, as on my next attempt the save loaded fine, but overall the above is still concerning to me.

As a precaution, I've cleared my system's cache. The TV error message persisted afterwards though.

Are there any other trouble shooting steps anyone can think of?

Overall, I'm still going to use and enjoy my console and if it conks out, well, it'll conk out. It's still under warranty as I've only had it since the beginning of October, but it'd be a shame if it dies on me this soon as I honestly haven't even used
the unit for gaming too much save for over this holiday.

Hopefully the above is all random flukes and such, but my gut is telling me otherwise.
