I have 1 PPR-B with a LED that's flashing (green). All my other PPR-Bs have LEDs all solid green. The pixels connected to the PPR with the flashing LED are all dark, so I guess the flashing means a problem. Anyone know what the flashing LED is telling me?

Thanks.
 
That LED is just powered from the on-board 5V regulator.
So if it is flashing - it indicates some sort of load/wiring issue etc is present that is killing the 5V.
 
Thanks.

The input voltage was +5V - expecting 24V. So I traced back and found a wonky connection back up the line. Cut the connector and re-soldered it, and all is well.
