Chapter 4 Maintenance

4.5 LED Board

It is very unlikely that the LED board will have to be replaced.

There are two indicators in the LED board: HDD and power. You

do not need to remove the backplane and bracket to replace the

LED board. Simply detach the bays for the FDD, HDD and slim

CD-ROM drive, and then unscrew the three screws fixed into the

panel. Before removing the LED board, carefully detach the cables

by pulling them down.

4.6 Touchscreen Controller

To service or replace the touchscreen controller:

1. Open the top and rear cover. (See Fig. 2-1.)

2. Disconnect the cable from the LCD controller and LCD.

3. Pull out the bracket which is located below the backplane.

4. Detach the bracket behind the front panel.

5. Disconnect the cables of the inverter, and the cables of the

touchscreen controller.

6. Replace the touchscreen controller.

Caution: Do not bend the touchscreen tail which is attached

to the touchscreen sensor.
