Try unplugging it from the wall - there is an issue with the xbox os where it sometimes soft locks.I think my launch day series X has give up the ghost, it has crashed a few times recently, I factory reset the console and this seemed to fix it but last night it crashed a couple of times and the last time I rebooted it there was a long message on screen but before I had a chance to read it, it crashed one last time.
After leaving it till today and power cycling it will not boot up, the power light comes on the console but there is no chime sound and no signal output, I have tried to boot into safe mode via holding eject and the link button but still no joy…..is it dead?
