Hello,
I installed a brand new top-of-the-line PCB (TWPC17A02502) in my mixer today. The problem is that the mixer boots up, but then no potentiometer is operable; the displays are lit. The test app in the mixer (press Quantize/Utility + Back button when powering on) works, and every potentiometer and button can be controlled through it. The firmware update to 1.7 also worked; at least it shows me 1.7 when booting up. Is there still an activation required somewhere, or is there a mechanical “safety” on the board? Curiously, my old board works.
