Series X turns off in seconds after being turned on

i found a fix by doing a power cycle by holding both controller power button and Xbox power button down for 10 seconds.

You're welcome and thank you for your kind understanding.

Hi, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

Seems like you have performed all the necessary steps. In this case, you're correct that it's an issue with the hardware itself and we may need to get it checked through Microsoft.

You can create a repair order by signing in to https://account.microsoft.com/devices and then add your console as a device using the serial number. If it's already added simply click on "info & support" and then start order.

You can register it online at account.microsoft.com/devices to check all your offers. If there’s any, it will also show how much it will cost you sending it for repair.

Is there any way i can send it to you guys for repair even though the warranty has expired?
