I replaced the encoder for Data Entry A and now all of my knobs have lost their push function. I can’t push and turn any knob for faster resolution, push a knob while in step record mode to untoggle a p-lock, etc, etc. No push function on any encoder at all. Has this happened to anyone else? I had a very hard time desoldering the encoder, so I wouldn’t doubt that I messed something up while struggling for hours during that step. Thank you. 
Too bad. Maybe you have soldered 2 points concerning push fonction. Check what you have soldered.
You can also remove encoder A, check the other encoders, see what’s critical for push. I you’re not sure, ask Elektron too.
