    • There is a wire connecting the motherboard to the inverter board. Squeeze both sides of the connector and pull to remove it from the socket.

    • There is another wire connecting the button board to the inverter board. Remove the second white wire connector.

    • A third wire connects the inverter board to the screen circuit board. Remove the black wire connector.

    The board you call the motherboard (the larger one) is the power supply/inverter. The power cord plugs into this and also the lamps are driven from here too (4 lamps: 2 blue/black 2 pink/white cables under the metal shield step 11)

    • Squeeze the plastic prong in the middle of the motherboard with a metal tweezer, while gently prying the other side with the plastic prying tool.

    • Be careful when using the metal tweezers. Make sure you do not make contact with any part that contains metal, for it may still have a charge. Discharge all capacitors.

    • This is easiest when the monitor is positioned such that motherboard is beneath the metal casing.
