How do get the boot screen? When I connect it to a screen nothing happens, it is not recognised at all, I’ve tried both hdmi ports. There does not seem to be signal to the screen.
If there is no HDMI output on the Nucleus, it sounds like there are hardware issues preventing the Nucleus from booting. I see your Roon account is currently registered from the UK, did you purchase the Nucleus from a UK Roon dealer? If so, you will want to reach out to the delaer to let them know of these issues, and they can then work with our UK Roon distributor for any needed repairs.
