Dear Forum members
on a HERMLE machine with ITNC 530 for some reason after a shut-down of the machine and the controller for a weekend (the machine was in working state and without an alarm while I shut it down) . When I returned after the weekend I could not Boot up the machine again .
I attached the relevant pictures , I want to know if you think it is a CCU problem or in the controller or any help will be much appreciated!.

Please let me know if there is anything else I can make a video or a photo that can help us in better understanding the problem's origin .

with appreciation
