DISASSEMBLY OF THE CD PLAYER BLOCK

1. 9CD3006900[C-01BD/A -DAEWOO]

The exchange of driving unit ass’y.

NOTE

Power must be supplied before the exchange. During the exchange, prevention band for static electricity must be in wear. (To avoid the damage of pick-up for static electricity)

A. Separation of D/U ass’y.

1. Short terminal (1) on pick-up PCB after separating mecha from set.

2.Take down D/U ass’y (2) through turning relay gear (3) in CCW direction.

3.Release screw (5).

4.Push slider ‘L’ (6) in the direction of screw (5).

5.Separate D/U ass’y (2).

B. Assembly of D/U ass’y.

1. Put D/U ass’y between slide ‘R’ (7) and slider ‘L’ (6).

2.Push slider ‘L’ (6) in the opposite direction of screw (5).

3.Lock screw (5).

4.Open terminal (1) on pick-up PCB.

5.Put mecha on set.
