Xbox turn off and on by itself

Hey AARC Caboose,

Very sorry to hear about this odd issue. After reading the steps you have tried to resolve the issue, your console may need to be repaired. First, I would check to see if you have a nearby friend or family member who has an Xbox One console to let you try
their power supply. This will fully rule out if it is a power issue on the console.

If the issue replicates on a different power supply, the next step will be to visit our Online Service Center to begin the repair process.

I'm assuming you are consulting around your xbox side (not wiring) but I will try and help with both methods.

Xbox Side:

Check if you have any power settings which may tell the xbox to turn off after so long.

If there is the disable it.

If there isn't then if your account is a child account check if the family timer is enabled - if so disable that.

Wiring Side:

Ensure your cables aren't stretching by dangling a major distance, if so this could be pulling the cable.

If this is not the issue then check the wire is in correctly.

Finally if it's non of these errors and you still have xbox warranty please contact Xbox Support.

Hope this help,

Brad.

I had this issue. It was a simple plug being loose in my brick.

Have you checked the power supply case to see if the light changes colour or if their is any loose wiring?

If you have relocated your console to a area that it has adequate ventilation, let the console cool down and the problem still exists I would advise you to submit a repair using the following
