Replacing the 12.1-Inch LCD Flex Cable
1. Pry the hinge-cover assembly apart from the display assembly, allowing just enough space for the flex cable to
pass through the opening.
2. Slide the cable through the opening.
3. Attach the flex-cable clip to the bottom of the hinge cover located at the bottom of the display assembly.
4. Slide the flex cable under the plastic strain-relief retainer located on the bottom of the display-assembly hinge
cover.
5. Reinstall the 4-mm screw that secures the metal cable clip to the left hinge of the display-assembly top cover.
6. Find the manufacturer ’s name on the back of the LCD panel that is to be installed. The manufacturer is either
Torisan or Sharp.
7. Fold the LCD flex cable at the crease shown in Figure 16 , so that the name of the LCD panel manufacturer
faces up.
The connectors on the Torisan and Sharp LCD panels are mounted in the reverse of each other. This
means that pin 1 on the Torisan panel connector is at the opposite end when compared to pin 1 on the
Sharp panel connector. Both panels have the same connector, but the connector is mounted differently.
The LCD flex cable can connect to either panel by making one fold to the cable. The words Torisan and
Sharp are printed on the cable (see
Figure 16 ). If you are installing a Torisan LCD panel, fold the cable
at the crease so the word Torisan is facing up. If you are installing a Sharp LCD panel, fold the cable at
the crease so the word Sharp is facing up.

Replacing the 12.1-Inch LCD Panel Inverter
To replace the 12.1-inch display LCD panel inverter, perform the following steps:
1. Find the manufacturer ’s name on the back of the LCD panel that is to be installed. The manufacturer is either
Torisan or Sharp.
2. Ensure that the inverter ’s configuration jumpers are set correctly (see Figure 17 ).
If you are installing a Sharp LCD panel, both jumpers are used. If you are installing a Torisan LCD panel,
the bottom jumper is used. See the sticker on the inverter shield for more information.
