Seems like my Nucleus+ got the same issue like similar cases recently. Can’t boot, can’t see from HDMI at all.
I need to unauthorize this Nucleus+ to bring back to the retailer to check. In the mean time, I will set up a different Core instead. Can you private me to help me unauthorize the failed Nucleus+ so I can set up Roon Core on another Intel NUC?
You don’t need to un-authorise it. When you sign in to the new core it will ask you if you want to make it your new core. If you select yes the old machine will be de-authorised.
