Removing the LCD Module
Before beginning any service work, remove all power to the unit and disconnect any signal cables where
necessary. Adopt static electricity working procedures when carrying out service work. Ensure
adequate lighting and use the correct tools. Access to the LCD module can only be achieved once the
CPU circuit board has been removed (see ‘Removing the CPU PCB’)
1)
Remove the 3 screws attaching the CPU PCB onto the LCD module (see fig.15)
2)
Flip the CPU circuit board over and remove the M3 nylock nut, earth wire and then remove the
M3 half-nut (see fig.16)
3)
Carefully de-solder the ribbon connector pins (see fig.15) and remove ribbon connector from the
LCD module.
4)
Retain the M3x25 screw with shake-proof washer and pillar once removed (see fig.15)
5)
The LCD module can now be removed from the CPU circuit board assembly.
To refit the LCD module, follow the above procedure in reverse order. Make sure all harnesses are
aligned and plugged on. Test for correct operation.
