ColorSource PAR power moisture sensor

I have been told that there may have been static build-up inside the fixture.  I do not know how it happens.  It can clear soon, or in a few days.  But it can happen again.  If it happens more than once, you might send it back to ETC especially if the unit is still under warranty.  Some of the units that I sent back came with a note saying "performed diode ECN and installed new power supply.  Added snubber network."  I do not know what all this means but obviously there was something that could be done.

What often happens in cases like this is either moisture buildup or a minor internal issue that temporarily resolves itself. Even though your theater has air-conditioning running 24/7, moisture can still sneak in, especially if there are temperature fluctuations or if the fixtures are exposed to humidity over time. Condensation inside the unit could easily cause a temporary short or disrupt the electronics, and during shipping or while sitting at the repair center, it may have dried out and started working again.
