[Smoking] Profoto D4
Mar 14, 2012

Was just wondering if anyone had also encountered this (so I'd know how to proceed):

Long story short.. I've had a D4 2400r running for a few hours now. Only two heads (6.0 / 6.0 / OFF / OFF) and I've not been using the modeling lights. Maybe taking about 5 or so shots every ten minutes.

At one point, the pack wouldn't fire. Lights are all still on (as is the Test button) but no dice. Saw a hint of white smoke (that was accompanied by 'that' aroma) and thought it'd be a good idea to unplug everything and wait a while. I searched around to see if anyone else had had this happen and I came across this article:

"Profoto packs, including the Acute 2, are wired with safety systems that prevent overheating. In the past, I’ve had Profoto packs slow down for cooling (including one memorable experience with a smoking Pro-7 rental that took an hour to start firing again)."

I've left the D4 for a while, plugged it back in, plugged a head in, turned on the modeling light (works), hit 'Test' - it beeps but doesn't fire. Smelled that smell again (the one where it smells like something electrical is being fried) so I powered down and have retired the pack for now.

Thoughts/suggestions/any idea (if it needs to be repaired) how much I'm looking at?
