Remove 10 screws (1 and 2) of rear panels. 2. Remove flat cable from connector (CN851 and CN852) of printed circuit board X

27、08 (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

28、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, remove screw (1 and 3) an

29、d FFC. 5. Remove 2 screws (8) of both sides of a panel. 6. Set up a receiver, so that the left side of a receiver becomes downward. And, remove 4 screws (9). Turn over a receiver like a figure after this. 7. Remove 5 screws (0) on the side of under of a panel. Next, remove 2 screws of radiators on t

30、he side of a base. And, remove a base plate to the back side (arrow direction). 8. Remove the solder of a power transistor from FOIL side of printed circuit board X09. And, exchange a power transistor. FIG. 1 FIG. 2 FIG. 3 RadioFans.CN 收音机爱 好者资料库 1060VR/1070VR/KR-V8090/KR-V9090 MRD MWR MRAS MCAS MD0
