2. Disconnect the cables from the front panel board assemblies and unplug the ribbon cable between the Playback and Program PCBs.
3. Remove the 19 phillips head screws securing the boards to the chassis, then separate the boards.
4. Remove the encoder buttons from the old board, then remove the keycaps, preferably with a proper keycap puller.
5. Install the encoder buttons and keycaps onto the new boards.
6. Secure the new boards to the front panel chassis using the 19 screws.
7. Install the new ribbon cable between the two boards.
8. Reconnect the power and data cables. Reposition the front panel into place and refasten the hex screws on the front and rear.
