LCD Backlight and LCD Driver Boards

  • Remove the four 6mm self-tapping screws securing both circuit boards.

  • Lift up and remove the LCD driver board (right).

  • Unplug the two small flex cables from the backlight board, being sure to properly unlatch the connectors first.

  • Flip the backlight power board over to the left, exposing the CCFL high voltage wires.

  • Disconnect the two CCFL high voltage wires.

  • The CCFL connectors can be challenging to remove. Try using a spudger to pry the connector+tiny board upwards while using your finger to pull sideways on the connector to disengage the latching tabs.

  • When replacing the backlight power board, be sure the two slider potentiometers engage with the plastic sliders on the front of the case.
