I have 4 Platinum 1200 Wash fixtures, all set to the same profile and in dmx mode and running through a Jands L5 using extended profile. Two fixtures work great, no issues and have been in services for years. The other two are not installed permanently. I put them in service for a special event and when powered on, pixels 8-19 will not fire. I tried manually testing and in test mode and they will not work. The fans spin up like the LEDs are firing but do not light up.
I've called Elation support and had not success. I've replaced the LED driver in one light and it did not fix. Factory reset does not help either. Any ideas?
