My QLink knob (Q5) is not working. However, if I move QLink 1 or 3 then Q5 is triggered and appears to move some. Do you think the slider needs replaced? Or is there some type of bleeding with the QLinks? I used a spray duster but that didn’t seem to help. Any suggestions are appreciated.

Update. I took the casing off the slider and sprayed with some Deoxit but still didn’t work. I then removed the metal casing surrounding the slider and cleaned everything including the contacts on the slider. I also lined up the connectors because they appeared a little bent. Then I put everything back together. I tested and it started working! Hopefully this helps someone. I got help by watching the link below. :nod:

I did that exact same thing with my EMU Turbo Phatt encoder dial.
Amazing how a lil TLC can work magic.
