Step 4Disassemble Keyboard
Disassemble the outer case. This consists of removing three Allen screws from the underside of the keyboard. The keyboard assembly then lifts out of the base.
Note that two ribbons are coming from the keyboard assembly and connected into the keyboard encoder circuit. Remember that keyboard matrix from the previous step? These ribbons are the X and Y axes of that matrix.
Depending on the manufacturer of our keyboard, these ribbon cables may be latched in or held with a pressure connector. In this case a pressure connector was used. To remove these, just pull on the tabs on both sides on the cable. Pull straight back to avoid damaging the cable. On the latched type connectors, we would need to open the latch on both sides of the connector. The ribbon should then slip easily out of the open connector.
Remove all screws holding the encoder board into place. We need to access the "solder side" of the board.
