PS Audio Nuwave DSD DAC

Wondering if I have an expensive boat anchor here...  Does PS Audio still exist?   My NuWave DAC just apparently died on me - the input selector status lights flashing in a mesmerizing rotation that I've never seen before.  No output from the unit.  I emailed PS Audio help desk - no response.  I just called them - no answer, and goes to a generic voice mailbox.  No info in the manual about troubleshooting this LED status display.

Does PS Audio still exist?  And/Or - does anyone have any intel on what the strange flashing LEDs might mean?  It probably needs to go back for repair - and if that's the case then back to my first question...

Thanks,
