· My Roon Nucleus Rev. B has stopped working completely and shows no signs of life. There are no LEDs on the unit and no Ethernet link or activity lights. I have tried different power outlets and replaced the AC power cable, but this made no difference. The unit remains entirely unresponsive, suggesting that it is not receiving power at all. The issue therefore appears to be either a failed external power supply or an internal power-related hardware fault. Please advise on the appropriate next steps.
We wanted to expand on our previous reply and provide some additional context.
The symptoms you’ve shared indicate that the power supply (most likely) or a failed internal power stage on the unit itself. This is something our Nucleus Hardware team will need to assess directly, so we’ve alerted the team to your inquiry.
They will, however, require some additional details from you in order to initiate the process. If you haven’t already, you can submit these details here by selecting “I have a hardware problem with my Nucleus.” The team will keep an eye out for this form and proceed from there via email.
