We use a Leprecon LPX-24 console at church. Four or five of the faders, when brought down to 0%, "creep" back up to 5% or 10%. Sometimes they stay up, sometimes they flicker between 0% and 5%. This even though the fader is physically at the bottom of it's travel. The really irksome thing is that two of these are "Playback" faders (other consoles would probably call them submasters, but Leprecon is, umm, different.) The moving light protocol is LTP only, so if I'm using Playback 4 at full intensity, but Playback 3 creeps up to 5%, suddenly my lights jump to a different scene! Maybe they'll even do a nifty dance between Playbacks 3 and 4! And hopefully it'll be during a very somber, introspective time!!! The workaround we've discovered is to very gingerly fade out the offending faders until they deactivate, but they're still a smidgen above the physical bottom. Is there a real solution for this, besides replacing parts? Can I clean them? Maybe they're corroded? I've never opened up a console before. I also need to replace the 3.5" floppy drive (really!!) so that I can do a show backup and hopefully install LED fixture profiles. Any help is appreciated! Thanks!
