Ok. I might check ... But is it possible that 2 years of non-use, and never any mechanical change/adjustment can cause this misalignment? Further, I never removed the PCB from the metal front, always removed the whole panel from the chassis (1 screw at each side). And the buttons all worked a week ago, I could enter any number and every number button stroke showed in the display ... so, removing the PCB now is perhaps not the first thing I would do right now. But I will keep it in mind! tnx, - Henk, PA8PDP.
