Morning,
some year ago I have had a similar issue with my realtively new X45Pro: It was dead and wasn't booting. I tipp from Audio-Michi helped:
Remove
all cables from the device and place it somewhere, where you can remove carefully the harddisk from the device (that is possible from the outside)
Now power the device and switch it on
without harddisk.
If the device has booted shut it down in a reagular way.
Unplug the power cable and reinstall carefully the harddisk.
Power it again and boot it.
Now it should boot from the HD as well.
If yes, have fun. If not contact the supplier
Good luck and no warranty from my side!
Lupo
