Removing the LCD Board
The following procedure assumes that you have removed the top enclosure from the unit. The
LCD Board is secured to a bezel that is attached to the Control Panel Board. When the LCD
Board is removed, the bezel remains attached to the Control Panel Board.
1. Disconnect the stranded wire cable that connects the LCD Board to the Backlight Board.
This cable is bent to form a loop. The loop portion is then inserted through a tie wrap that
is affixed to the Backlight Board mounting plate. Disconnecting the cable should pull the
cable free of the tie wrap.
2. Remove the cable locking clip and disconnect the flat ribbon cable that connects the LCD
Board to location J804 in the CPU Board.
3. Remove the four screws that secure the LCD Board to the bezel.
4. Remove the LCD Board.
Replacing the LCD Board
1. Place the LCD Board in position face down onto the bezel. The placement of the LCD
Board should seem obvious because of cable length and positioning. However to
eliminate any question, be sure that the arrow imprinted on the back of the LCD Board is
pointed toward the rear panel.
2. Install the four screws that secure the LCD Board to the bezel.
3. Connect the flat ribbon cable that connects the LCD Board to the CPU Board. Be sure to
install the cable locking clip.
4. Connect the stranded wire cable that connects the LCD Board to the Backlight Board. Be
sure to position the cable to insert it as a loop into the tie wrap secured to the Backlight
Board mounting plate.
