Nucleus cannot startup anymore

My nucleus rev.B suddenly cannot startup anymore. iPad cannot find it out. And I tried to connect to the monitor thru MDMS, but it keeps “roon” logo even if press on “Enter” key on USB keyboard.

Please give your instruction how to initialize it.

Hey @Hiroyuki_Kahata,

We’re so sorry to hear that your Nucleus doesn’t seem to power on. We’d love to help out and discover what the best next step is (sometimes that is, as @mikeb has said, contacting the local dealer you purchased the Nucleus from).

Could you please let us know what lights are on on the back of your Nucleus?
Could you please connect an external monitor via HDMI to the Nucleus and share a photo of what’s displayed on it?

Thanks in advance :pray:
