This Korg Wavestation had some cold solder joints, needed some new buttons/switches and a fresh new display. I cleaned the slider and rotary and found some leaky capacitors (again) in the old display. In the first try I found out, that PIN 19 (font size) was not connected and the display showed some issues. It works with PIN 19 pulled to 5V.
I’m documenting repairs for my reference and yours.
