DISASSEMBLY FOR REPAIR
The method that exchanges a power transistor.
1. Remove 10 screws (1 and 2) of rear panels.
2. Remove flat cable from connector (CN851 and CN852) of
printed circuit board X08 (A/3) . And, remove one screw
(3). After this, move printed circuit board X08 (A/3)
toward the right.
3. Remove one screws (4) of printed circuit board X08
(B/3). After this, move printed circuit board X08 (B/3)
toward the right.
4. 1) Cut certain 4 convenes with nippers etc. on the left side
of the power supply transformer.
2) Remove one screws (6) of printed circuit board X14
(C/5). And, remove a headphone unit.
3) Remove 4 screws (7) of printed circuit board X09.
· Make printed circuit board X08 (A/3 and B/3) in
original condition, after screw (4) is removed. And, FIG. 1
remove screw (1 and 3) and FFC.
5. Remove 2 screws (8) of both sides of a panel.
