I have a Nucleus with no storage. SN 54B203F6B180.
Wired ethernet from Comcast modem.
Parasound P6 and Dynaudio speakers
Just Quboz and Tidal
Nucleus won’t power on. Tried different outlets. Don’t know if it’s the unit or the adapter. Was after some electrical storms and an internet outage. It’s on a surge protector.
Try plugging in a monitor and keyboard and then booting the Nucleus. Is there anything on the display?
The blue power light won’t come on. Would a monitor / keyboard change that?
Probably not, but, the power light indicator could be bad, so it doesn’t hurt to verify.
Did you purchase the Nucleus from a dealer? If so, then, you might want to contact them. If you bought it from Roon, then Roon will engage when support returns after the weekend.
Ok, gave the monitor / keyboard a try. No signal, no blue power light, doesn’t show up on network, etc.
I purchased direct from Roon so will wait to hear from them on Monday. Thanks!
Hey @rjr108,
Ben with the support team here, thanks for writing in, and my apologies for your Nucleus troubles. 
I’ll follow up via private message with next steps. Thanks @Rugby for the help thus far! 
PSU can be bad. You can try any PSU that is at least 12VDC/2A with a standard 2.5/5.5mm connector.
