One of my original design spot 250's will run fine for a few minutes then starts having issues. It appears that the first thing to crap out is the shutter then everything but the pan and tilt. I can reset the fixture and everything will function again but only for a few minutes before the same errors occur. Eventually resetting the fixture does nothing and i get the following errors: 05, 06, 07, 08, 09, 10, 13.

Any suggestions?

remove both head covers and inspect the head PCB. see if the there are heat marks around the drivers.if so then the head pcb is most likely bad.

i switched the head PCB with one from one of my working ds250's and the same problem occurred.

ok, try replacing the ARM PCB as well.

i swapped the arm PCBs and now bot fixtures have been operating fine on auto mode for the past 10 minutes. I don't understand how that would happen. Any ideas?
