There are 8 ribbon cables that need to be removed as shown in the picture.

2 of connectors (in green) are friction fit, unlike the rest of the connectors. Remove the cable by pulling it out gently. Do not attempt to open or unlatch these connectors in any way. Doing so will break them.

For the remaining 6 (in red), use a pair of tweezers to flip the latches up and pull the ribbon cable out.

Note that the second picture shows a broken ribbon connector next to the joystick ribbon connector (to the right of the red arrow). Do not attempt to unlatch this connector as shown in the picture!
