Hello everyone!
Thanks for your replies to this thread. I'd thought I'd chime in here since I'm Seth's boss, and can fill in some on the backstory that Seth missed previously. Some of this is cut and paste from e-mails sent to vendors, so apologies for changing tenses,
etc.
This first happened with a
unit last summer. I pulled it off of the pipe, replaced it with another, and took it to the shop to diagnose it. It worked fine, and since I could not recreate it, it went back into
stock.
This past fall, it happened again. I unfortunately do not know if it was the same
fixture or not, since they get moved around a fair
bit, and are not currently individually labeled.
The segments that aren't flashing will continue to bring up the color as
DMX is telling it to from the
console. When it was doing this, we tried:
1) Unplugging and re-plugging the unit- once rebooted there was no change.
2) Switching from
dimmer at full
power to a wall outlet- once booted up there was no change.
3) Unplugging the DMX- no change in the flashing.
When I have the
unit plugged in to the wall, not connected to
DMX, and I scroll through the control options, it seems to flash only when an
RGB control option is selected. When the HSI options are selected, it stops.
We started using
DMX terminators after this happened in the fall.
The units we had problems with in the fall are at our vendor being prepped to ship to
Chroma Q for repair. The control module was checked and deemed OK, so they want to open the
fixture up.
The video Seth posted was from just the other day, from a THIRD
UNIT that is having this issue. The
unit made it through several days of tech with no problem, but suddenly started flashing. Maybe a coincidence, but I noticed it was right after a newly programmed moving light sequence was triggered for the show. This
unit is being powered from a standard 110
outlet, so no
dimmer.
Seth is currently checking the
DMX runs to verify location in the chain of the moving lights and dmx-branch, as well as verify
DMX and not
microphone cable is in use.
The units we had problems with previously got so bad that they would flash immediately upon being powered up, without any
DMX.
Seth has gotten a reply elsewhere that states this is a "known issue" with a
strain relief in the
fixture, but I saw no complaints about these fixtures anywhere when I was searching last fall.
Thanks again for your responses... anything else you can tell us to try to determine the root cause of this will be greatly appreciated.
