unfortunately if we can't replicate a problem based off user's description, it's really hard if not impossible to diagnose the issue. From what I can see here and not being able to replicate the problem, I can only say that a hardware problem should be the issue. Thus the unit should come back at the factory for servicing.
Since I understand the unit is brand new, you may want to contact your dealer and check if they may help you or you need to contact firstname.lastname@example.org.
I'm sorry for the problems you are having but I'm not able to replicate the ones you have described, Thomas.
