There a few reasons that cause this: https://support.sonos.com/en-gb/article/sonos-led-lights  Has this device been factory reset?  Has the Move ever connected?

Yes, I did try the factory reset, to no avail.  I’ve used this speaker for 2 years without issues until now.  One day it was just blinking white and I could get it to white and Orange, but no further.  

Additional info.  I have other Sonos speakers that are working just fine.  They are used with Beam for surround sound for tv.  The Move is used by itself in a separate room. 

In that case I suggest that you call Sonos technical support, they have a lot more diagnostic tools available to them.
