Note: The shape of the monitor assembly varies by the size of the LCD screen.

For the 3.5”-type LCD, refer to Fig. 1-4-2.

1.4.3Disassembly/assembly of monitor assembly (for 3.5”-type LCD)

Note: Be careful not to soil or scratch the monitor screen through the disassembly/assembly work.

1.Remove the four screws 1 to 4 in numerical order. While disengaging the six hooks (L4a to L4f) in alphabetical order, remove the monitor cover assembly.

Note4e: When removing the monitor cover assembly, be careful not to damage the FPC and connector.

3.Unplug the wires and FPCs from the two connectors b , c , and then remove the MONITOR BL board assembly, holder (PWB) and backlight in that order.

4.Remove the LCD module while disengaging it from the four hooks (L4g, L4h, L4j, L4k,).

1.4.4Disassembly/assembly of hinge assembly (for 3.5”-type LCD)

1.Remove the three screws (5 to 7), and then remove the hinge covers (1) and (2) by disengaging a total of four hooks (L4m, L4n) at the two sides.

2.Separate the SW board assembly and the FPC from the hinge assembly.

2.Unlock the connector a and then disconnect the FPC while lifting the hinge assembly upwards to remove it to- gether with the FPC.

Note4f: For disconnecting the FPC, unlock the connector first and then lift the hinge assembly upwards. Accordingly, the FPC is disconnected together with the hinge assembly.

Note4g: Treat the wires carefully.

Note4h: When disassembling/assembling the hinge assem- bly, pay careful attention to every part not to dam- age anything.

Note4j: When connecting the FPC, arrange the FPC wire by winding it around the shaft (hinge pin) of the hinge assembly by two and a half turns while pay- ing heed to the orientation of the hinge assembly and FPC.
