NOTE: Do not use excessive force when fastening the LCD Display component to the metal
frame. Fastening the screws too tightly might bend the display module too much and break it.
The screws must also be fastened gradually: first fasten all screws slightly, then more tightly.
NOTE: When reassembling the LCD Display Unit, be careful that no dirt or fingerprints are left
between the LCD Display component and the protection glass window.
NOTE: If the LCD Display Unit is broken, handle it carefully to avoid injury (the LCD Display
component and the backlight lamp(s) are made of glass). Wash your hands if you touched
liquid crystal, which may flow out from a broken LCD Display component.
NOTE: Do not touch, push or rub the exposed display module surface. Keep the surface clean.
Replacing the backlight unit

cable at the display side.

the LCD Controller Board. Place the rear cover with the video cable aside.

6. Open the 15 screws holding the LCD Controller Board in the LCD Display Unit. Detach the
LCD Controller Board carefully from the LCD Display Unit (connector X102 underneath

7. Disconnect the backlight unit cables carefully from the Inverter Board. Open the six
screws holding the LCD Display Unit metal frame in the display front cover. Detach the
upper part of the metal frame.
8. Lift the LCD Display Unit together with lower part of the metal frame carefully up and
place it on a clean surface with the display screen side down.
