Description of Issue

Unable to link after power outage and HDMI/Keyboard connection is also not working. This happened in Nov and it corrected itself without any intervention on my part, but this time, nothing seems to work. Everything on the network reset when the power went out, so there may be configuration elements that need to be reset. I have seen other posts that indicate the unit may need to be sent for repairs? I purchased this unit direct from Roon less than a year ago.

Thanks for your help!

Hook it to a monitor or TV by HDMI. What does it read during startup?

Also - does the Nucleus show up in the Nighthawk’s list of connected network devices?

Thanks, Bernd - The TV sees the device is connected but it looks like the Roon is not passing signal - It says, ‘check device power.’ Everything is on and plugged in. The only possible variable is I have an apple USB keyboard plugged in to it.

Looking at the Nighthawk admin panel, it’s either one of three generic devices at 192.168.1.26 (00:11:D9:7A:13:d4), 192.168.1.2 (00:0E:F3:54:13:1A), 192.168.1.16 (CC:5B:31:BB:20:93) or Laptop-0CDCC78T at 192.168.1.5 (00:0D:B9:5E:11:94)

Not a good sign. At least during boot up the Nucleus should throw some messages to the screen. With a bit of luck the power outage only killed the power supply. But that’s just me guessing.

Thanks, Bernd - I ordered another power supply just in case. It looks like it has power, but it’s worth a try. I’m not sure if my samsung tv is willing to just pass the hdmi signal - seems like it’s trying to do its own thing there, so I’m not 100% sure we can isolate just the nucleus yet.

Good luck. I hope you can return it in case it’s not the root cause :grimacing:

Thanks, Bernd - I was able to make a direct HDMI connection to it and there is no display at startup or ever - Just a blank/black screen. Rebooting doesn’t seem to help it. I’ve seen this referenced on a few other threads as well. I worry this thing is bricked.

Well, maybe not the end of the world.

If you purchased this less than a year ago direct from Roon then they will arrange a RMA for you to send it back.
I’m going to page @support here and they will dive into this as soon as they can.

Right on - thanks both. I emailed the contact address. Your help is much appreciated!

Hi @J_Pierson ,

This does sound like the unit is in need of an RMA, I’ve followed up via private message to gather purchase details from you, thanks!
