My Xbox One is not turning on

Check the Power Supply unit if is outside buy a new one if not go to a Microsoft Store to check the xbox

Which Xbox One Console do you have? Xbox One original (external power brick), Xbox One S, or Xbox One X? It might be a power supply failure if you've had any recent power surges or outages without your console being plugged into a surge protector. If you
have the Xbox One original, then buying a new power supply brick may solve your problem.

I have this exact same issue and its been 6 months

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Is this the Xbox One Original, Xbox One S, or Xbox One X?

Also, please try using a different wall socket and if you have an external hard drive plugged into your console please unplug it in the meantime because a corrupted hard drive may cause these issues as well.

Is there a way that I could change the power supply without sending it in for repairs or buying a new console? Also, is there a way to test if the power supply is 100% the problem? My parents are not sure and need proof.
