I know, throw them away! But I've gotta try before the venue will buy new fixtures. I've got about 30 of these and a few have issues. The most recent one that has stumped me is one of the units won't strike the lamp. I tested a bunch of things and decided to swap the motherboard with a known working unit (trying to clear a magenta error too - turned out being the driver on the board) and when I put in the working motherboard in the unit, it striked the lamp. Could it be something on the motherboard that's not letting the lamp strike? Thanks!
