When separating the motherboard from the front cover, be careful not to disconnect the two red wires which connect the speaker to the motherboard.

Remove the two 6.8 mm Philips #00 screws located on the top left and right corners of the motherboard.

Gently lift the motherboard away from the speaker case.

Remove old buttons and place new buttons into the button slot.

If button issues continue after button replacement, refer to the motherboard replacement guide.
