Just for anyones information with a problem I had with 2 5Ps, one was an older model and the other more recently purchased.

The lights stopped receiving DMX signals but everything else seemed to be functioning properly.  I happened to check the resistance between pins and got the following:

  • 25kΩ between + and - pins
  • 15kΩ between + and gnd pins
  • 10kΩ between - and gnd pins

It seems that for a working fixture, the pin resistances are:

  • 38kΩ between + and - pins 
  • 28kΩ between + and gnd pins  
  • 10kΩ between - and gnd pins  

It seems that somewhere on the Main PCB had failed as a replacement of the board had remedied the problem.

So if this same symptoms happen for you as well, a quick ohmmeter test can let you know what is likely wrong before taking it apart.
