Greetings,
I help out some NYC schools with their sound & lighting equipment and have run into a problem that's stumping me.
Strand CD80 AE dimmer rack, installed c. 1995, 18 dual-circuit 2.4K dimmers, probably hasn't been used in 5+ years; students trashed the NSI/Leviton MC 24/48 console (don't know if it works); a dozen Altman StarPars, a few ellipsoidals (pbly 360Qs), a smattering of PAR cans - no idea what lamps are burned out or intact.
The issue is - No light fixtures respond to fader changes issued from a DMX control console even though the rack indicates INPUT A is present.
Troubleshooting steps taken:
From what I've gleaned from the CD80 AE manual, the above is largely expected behavior - except for not responding to the DMX console commands. Most of the tests were performed with the Program switch on and off.
Any advice for next troubleshooting steps would be appreciated. I've tried calling and emailing Strand support personnel w/o any response, so far.
Thanks,
Keith

Troubleshooting steps taken:
- Connected 2 different DMX consoles (Elation Stage Setter 24 & Elation SDC12) to a DMX input wall jack and INPUT A light lit on Input Processor module
- No lights responded to fader controls
- Removed the F1 fuse from the power module
- The rack powered off
- Removed the F2 fuse from the power module
- Several lights came on at full intensity
- Removed the F3 fuse from the power module
- Another set of lights came on at full intensity
