Disassembly Procedure
(How to Remove the Main Board)
1.
Remove the all bottom screws.
fig.E09-01
2.
Detach the bottom carefully (Lift the keyboard side of bottom and open
it so that the rear panel side should be a fulcrum, because the speaker
cable is connected).
fig.E09-02
3.
Detach the speaker cable wound with a ferrite core that is soldered to the
mainboard. (The bottom can be separated.)
(If the component is attached by a connector instead of being soldered, detach
the connector.)

5.
Remove the 4 screws securing the mainboard.

the circuit board). Watch carefully while removing to ensure that no wiring is
severed or disconnected.
