Remove the tape that holds the LED board. The LED board is taped to the battery assembly.

Three wires or a ribbon cable connect this board - be careful not to bend these wires - they break easily and it's almost impossible to get to them. I suggest you tape where they join to the main board while you work on it so they don't keep bending back and forth.

You can use the blue opening picks again both to help peel the tape back some and to push in between the circuit board and the black plastic snap hooks.
