Electronic circuit board (PCB) repair

Using a Phillips screwdriver, carefully remove the 2 screws at the front and back of the lamp's body.

Screws are small and light, so make sure to place them in a safe spot to avoid losing them.

Carefully separate the two parts of the lamp by pulling the white shade and the black base in opposite directions.

After removing the shade, the main electronic circuit board (PCB) will be exposed.

Using a Phillips head screwdriver, remove the 6 screws around the entire perimeter of the board.

Once all 6 screws have been removed, carefully separate the white plastic frame from the black base of the lamp.

Make sure to pull gently as cables connect the two parts.

Underneath the PCB, there are 3 sets of cables. 

Gently pull the cables away from the circuit board and disconnect everything. 

Remove the PCB from the lamp, and take the plastic frame around the circuit board off.

The PCB you removed contains valuable materials and minerals. To maximize its chances of being recycled, it should be disposed of as e-waste and handed over to a recycler.

Assemble the new PCB into the plastic frame. Each part has a straight edge on one side; ensure they are aligned.

LEDs must be facing up when the circuit board sits in the frame.

Reconnect the battery cables to the PCB connector. Make sure to use the connector next to the round edge of the frame.

Reverse each step from steps 4 to 1 to reassemble the lamp.

Align and lightly press down the circuit board and frame until it sits in place.
