DISASSEMBLY/ ASSEMBLY PROCEDURES
5.5 Slide the violet (14) and gray (15)
grommets away from the slots in each
corner of the mechanism.
5.6 Remove the two screws (13) that
secure the cover (12) to the mechanism.
Unsnap the cover from the mechanism.
6. CD Mechanism Replacement
6.1 Snap the cover (12) into position. Align
the screw holes and replace the two screws
(13) that secure the cover to the mecha-
nism (11).
6.2 Slide the violet (14) and gray (15)
grommets into their respective slots on
each corner of the mechanism. See Figure
3 for their proper locations.
6.3 Connect the 6 pin connector to the PCB
that is connected to the motors and the 5
pin (with black cable) and 8 pin
connectors to the APC PCB.
6.4 Remove the solder from the shorted
points shown in Figure 4.
Note: Make sure that four nylon washers
(23) are mounted on the posts before
installing the mechanism (later models
only).
Note: The CD mechanism wires must be
routed correctly (see Figure 7) for proper
CD operation. A sign of improper routing is
a clicking noise when playing tracks at the
outermost edge of the CD. Perform the CD
Final Verification tests on page 31 to
ensure proper operation.
6.5 Place the mechanism on the four metal
posts located in the base (19). Position as
shown in Figure 3.
6.6 Replace the door/right cover assembly
(Procedure 4) and left cover assembly
(Procedure 2).
7. Digital PCB Removal
Note: Refer to Figures 3 and 7 for Proce-
dures 7 and 8.
7.1 Remove the left cover assembly (Pro-
cedure 1) and the right cover/door assem-
bly (Procedure 3).
7.2 Lift up the CD mechanism (11) and
move it aside. Keep the mechanism con-
nected to the PCB unless removal is
required. See Procedure 5 for removal
procedure.
7.3 There are four black plastic tabs that
hold the PCB (10) in position. See Figure 3.
Flex them carefully outward and pull the
PCB up and out.
7.4 Remove any connections required to
troubleshoot the PCB.
8. Digital PCB Replacement
8.1 Replace any connections that were
disconnected during troubleshooting.
8.2 Slide the PCB (10) into position. There
are notches in the PCB which mate with
notches in the base (19). See Figure 7.
8.3 Snap the PCB carefully down under the
four locking tabs.
8.4 Push the CD mechanism (11) down
onto the four metal posts.
8.5 Replace the right cover/door assembly
(Procedure 4) and the left cover assembly
(Procedure 2).
9. Audio PCB Removal
Note: Refer to Figures 3 and 7 for Proce-
dures 9 and 10.
9.1 Remove the left cover assembly (Pro-
cedure 1), the door/right cover assembly
(Procedure 3), and the Digital PCB (Proce-
dure 7).
9.2 There are four locking tabs (three on
the PCB edges and one in the middle of the
PCB) that secure the PCB (10) to the base
(19). Flex the tabs carefully away from the
PCB and disengage the PCB.
