Guys, i got it!! I found how to solve the ghostly issues. I discovered a bad capacitor on the screen board. I changed it and now it´s perfect. It's a 10uf SMD electrolitic capacitor, and I changed it for a regular one. Check the picture. \o/

I had the same situation. I got the solution, I inverted the manual instructions. I first hit the model knob then the tap. Successful

I also had a similar problem with the M9. When I turn it on the potentiometers change doesn't work and change the sets itself randomly. When I try to set them up, they don't work. Only the model encoder works. After 1 hour warming on, the pots start to work but not the full range, just 20% up and down. After several hours with it on, the pots begin to work, but it's not possible to set them at the lowest position (first 10% of the range). I opened and checked the voltages at the moment I turned it on and after several hours nothing had changed. The voltages were a little out: 12.8 / -11.6 / 4.8 / 3.2 v. I cleaned all pcb and pots very well, checked all flat cables, everything is fine. Power supply sends 10.5 volts A/C. I believe it can be a capacitor. I will try to change the electrolytic ones to see if I get any success. If anyone finds a solution please share with us.
