Removing the Backlight Board
1. Disconnect the stranded wire cable that connects the Backlight Board to the LCD 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. Disconnect the stranded wire cable from the Power Supply Board to the Backlight Board.
3. The Backlight Board is secured to a mounting plate. The mounting plate is secured to the
top enclosure with two screws at one edge of the mounting plate (rear panel edge); the
other edge fits into a groove on the enclosure support wall.
4. Remove the two screws that secure the mounting plate to the top enclosure.
5. Slide the mounting bracket toward the rear panel.

screws also secure a shield over the board.
