Just ran through some trouble-shooting with the gang at PS Audio regarding the display on my NPC not working other than very briefly during power-on or reset. We tried to power cycle it, tried the reset button, installed the latest (0.55) firmware but none worked.
During one power-cycle I unplugged the USB cable that connects it to my Mac, powered it on and it worked normally. The display came on for the set 10 seconds and awoke at a button press. Hopeful, I turned it off and reconnected the USB cable, powered it back on and it was back to it’s brief illumination and non-responsive to button presses.
So I tried a different USB cable - didn’t fix the issue.
We tried connecting it to a Windows based PC - this didn’t work issue.
But as soon as I unplug the USB cable from it and power it up it works fine.
They’re working on an RMA for me but I’m curious to see if any other NPC owners have experienced this?
