All 4 knobs not working

Post by SynthGraphics » Tue Mar 12, 2024 3:02 pm

Recently picked up a "non-working" LP, non-USB version. It plays, all the buttons work, etc. However all 4 big knobs don't work - they jump from full on and off only. I had a tech look at it and he thought maybe the board controller CPU/ROM was bad, reached out to Moog for parts, etc, but never heard back from Moog.

Anyone else had this same problem? Thanks :)

Moog have recently changed their contact platform, you need to apply here https://moogmusic-help.freshdesk.com (click on the sublink at the bottom of the page to login as Customer)

Back to your issue, I find it is simplistic jsut to say that "CPU/ROM are bad" since all the rest is working (as you report), only a qualified technician who has the LP schematic and knows which component(s) are involved in the scanning the 4 pots can diagnose the problem properly.

Replacing encoders is a more common fix than a bad CPU/ROM. If you're not comfy soldering, getting a quote from a synth repair shop might be the way to go. Good luck getting that LP back in top shape!
