Xbox one x won’t turn on

Make sure that you plug it directly into the wall. Not through a power strip. unplug the console for about 2 minutes so the console can reset itself. Then plug it directly into the wall socket.

That didn’t work at all

There was a large post on reddit that went away where basically the power cords in some X's were loose. Might need a new power cord or REALLY jam it in there to make sure your good.

Hello! A buzzing noise? Not even my second hand Xbox One S does that...a small subtle bee sound it does very rarely, mostly when loading up a large area in a game. Or if it's online game, it likes to do that a lot. But its subtle.

Is your Xbox One X second hand? Hmm. Well somewhat good news, its one of the more commonly reported issues with Xbox One X, which means there's likely a work around figured out by the people crying out for help to get it fixed.

As I suspected, its a likely related issue with the power brick. But I'll do you one solid and reference you a well sought out article explaining the troubleshooting guide "before" you just conclude its the power bricks problemo and it needs a kabamo (replacement)

As always if this doesn't fix it, let me know, or if you have a warranty replacement on your Xbox One X, it might be time to use that gold card.

Another issue being reported by users is that the system won’t power on, or if it does, it is for a limited time only and then quickly shuts off. This could be the console itself, but it is more likely the
power brick.

Possible solutions:

The first step is always to simply check to make sure everything is connected properly. Once that is done, the next step is to verify that your power brick is working properly. All Xbox One power bricks have
a light on them to signify they are receiving electrical current. If you see a solid white or solid orange light, the power supply is working properly.
If there is no light or it flickers, it needs to be replaced. Before you contact Microsoft though, try these quick fixes.

• Make sure it is not the outlet you are connected to. Plug something else in, or try plugging the power supply into another outlet.
• If the power supply isn’t receiving current, it’s defective and needs to be replaced. If you registered your console, you can order a new power supply online.
• If the power supply is working but the Xbox One still isn’t powering up, contact Microsoft directly, as it may be a defect with the system.
• If the controller isn’t powering on your console, try pressing the power button on your console directly. Occasional syncing issues can cause this to occur.
• The problem could also be completely unrelated to your console. Intermittent issues with Xbox Live has resulted in some users
  seeing black screens when attempting to turn their systems on. Some have found success in disconnecting their internet in order to still play games, but the only other solution is to wait for Microsoft to resolve its own server problems.

Make sure that you plug it directly into the wall. Not through a power strip. unplug the console for about 2 minutes so the console can reset itself. Then plug it directly into the wall socket.
