The main power board is located directly behind the power button, screwed into the front plate.

Locate the LED board. It is located in the base of the globe, with the LEDs extending up inside the globe.

Trace the wires coming from the LED board to the main board. Pull out the white clip connecting the wires from the LED board from the socket on the main board. This will sever the electrical connection between the LED board and the rest of the lantern.

In this case, the white clip contains wires from both the LED board and the top solar panel. In order to replace the LED board, the wires connected to the solar panel must be unsoldered.
