PIXIE 8 - Single port string stuck/frozen at all white during show

SAUF: Looks like for some RGB light strings, this is what happens when the current drops below a certain threshold (In my case because of running 50 ft of RGB wiring) 

Symptom:   When running certain sequences, 1 port on the PIXIE 8 would have its lights get stuck at on/WHITE and would not change until power off. 

Things I tried

  • Hardware Utility - would not affect string at all - power down required to turn it off. 
  • Upgraded firmware on Pixie 8 to 1.08 - same behavior 
  • Swapped ports around - same string would still get stuck 
  • Swapped out light string - new string at same position would still get stuck 
  • Check new string on same port with shorter wire - string works correctly 

I will rig up a remote 12V power near the string and put in a power injector.   Will reply on this thread if it works. 

Main thing is I thought the lights would not work at all with insufficient current, but it looks like there are graduated symptoms.   I guess the control chips need more power than the actual LED elements.

Looks like that was the issue.  Found a simple 12V 2 amp surplus A/C adapter and used a power injector and now the lights are behaving normally.
