Xbox one won’t turn on. & it’s NOT the power brick.

It would seem the issue is with your power brick. Do you have any means of trying another power brick(borrow a friends?) to see if the cause is isolated to the brick itself and hopefully not your console.

This sounds like it could be a ventilation issue and you may need to send it in for service. Here is the link to get started

Thanks for the reply, but servicing is not an option for me because I moved from the US to a country not on the supported list for servicing. I left a spare power brick back home in the US. Could using that power brick possibly solve the issue? I can’t tell
if it’s my console or my power brick malfunctioning.

sorry, didnt help. i did order a new power brick online though

With almost any problem I have on my Xbox, before calling Microsoft support to help, I do a few things that often fix the issue. Have you tried turning your Xbox on with the controller rather than by pressing the button? Unplugging the console from the
power brick and unplugging the power brick from the wall for 30 seconds will often do the trick. Wait until the light on the power brick goes off to ensure it has completely reset. Also ensure that all plugs are pushed in tight, as that is a common problem
with my Xbox not turning on. Hope this helps!

So I had this issue with my original xbox one too but before I paid to get it fixed I borrowed my brother power brick to see if it would work and it did.Check to see if it's not the power brick.
