Casio LK-170 Display Replacement

Using JIS-1 screwdriver, remove the seven 11mm screws located on the back of the keyboard.

Once all the screws are out, flip the keyboard over and gently pull the middle panel out.

Flip this panel up so that the component board can be seen.

First, you must use the PH-1 bit to remove the 17 8mm screws, circled in red.

Second, using the same PH-1 bit, you will remove the three 8mm screws hidden under the white wire. These screws are circled in orange.

Third, using the JIS-1 bit, remove the three 7mm screws on the circuit board.

Using the PH-1 bit, remove the last three 8mm screws, circled in green.

Once all the screws have been removed, lift the component board and place it face down on the keys.

Flip over the component board to reveal the display that is currently connected to a green panel.

Remove the display by carefully picking it up with your fingers from the green panel.
