Likely a hardware issue.

Another test would be to wire the Kitchen player to the network. The network port lights should not be lit until you attach the network cable. 

Thanks buzz

no light when change Ethernet cable to kitchen unit… nothing at all. 
 

So guess that means hardware? 

Very likely a hardware failure. A very slight possibility is that the buttons you are pressing are defective and the unit does not actually reset. As I recall, the wired port lights will not start flashing until late in the reset process. Normally, the lights will start flashing shortly after power up. I have seen a failure where the lights will turn ON without any connection.

Avoid Factory Reset of the working unit because this will trash all of your settings.

Was hardware failure. Thanks
