To disassemble the controller, start by removing the seven Phillips head screws located around the perimeter of the controller's backside.
Gently separate the two halves and disconnect the red connector from the PCB, which leads to the battery compartment on the back half.
Lastly, there are three more small Phillips screws that need to be removed inside the controller. Two of these screws secure the speaker bracket, while the third one holds the PCB in place.
Pay close attention to the positions of the internal screws, as there are more screw holes than actual screws.
