Today I got my replacement 61-keyboard from Arturia.
I removed all the outer screws
and disconnected the ribbon cable and 2-wire aftertouch cable. (note I marked the cable that connected to the small arrow on the connector)
I then removed the 20 screws that held the 61-keyboard to the bottom plate.
I reversed the process to re-install the 61-keyboard to the bottom plate.
Re-connected the ribbon and aftertouch cable.
Re-installed the outer screws to the upper Part of the KeyLab.
powered up KeyLab-61 everything works fine.
