D40's Flashing in random cues


We have a brand new system as of February 2017.

We're running an ION 2000.   I have mostly S4 Lustrs, D40's, Color Pars hooked up to the system.

I also have a few Altman 6x9's hooked up through a dimmer rack.


We started to get some random flashes from the D40's in the middle of a cue.

It would happen maybe twice a show.  Sometimes in the same cue/ light.  But also, in different.

I reset the relays and it fixes it for a show but then comes back.  Also, the board is power cycled every show.



Thank you,
