Description of Issue

Currently at clients house troubleshooting roon nucleus that fell off network. Green ethernet light is blinking. Tried power cycling and still nothing. Hooked up HDMI to TV and don’t get any error messages or output from it. Please advise with resolution steps.

If you power cycle the Nucleus, do you see anything on HDMI?


No, when I power cycled it I didn’t see anything on the screen. Is going to be an OS hard drive issue?

The fact you saw nothing, including BIOS and boot loader message, would suggest it’s more than a disk failure.

Just to be sure, can you try the web interface, as described here.

Was unable to reach the web interface. What are our clients repair options going to be?

When was it purchased? Does it still have warranty?
