Maybe wait till it stops synching and see if it starts mining, CPU might be overloaded
Thanks! I'll also inspect the wiring harness for any wires that may have disconnected or snapped during shipment--another user suggested that.
Weeeeeell...same issue. I stopped the node (thus removing the load on CPU) and restarted the miner(s). No change--solid red light on FULL but STANDARD hashes away in Eco fine.
Will wait for blockchain to fully sync (90% currently) and retry all the rebooting steps.
I can't see any loose wires or anything, so if there's no progress after full sync, I guess it'll have to be returned and swapped out for a new FULL?
