2. Disassembly Method
(1): Identification (location) No. of parts in the figures
(2): Name of the part
(3): Figure Number for reference
(4): Identification of parts to be removed, unhooked,
unlocked, released, unplugged, unclamped, or
desoldered.
P=Spring, L=Locking Tab, S=Screw, CN=Connector,
W=Washer
*=Unhook, Unlock, Release, Unplug, or Desolder
e.g. 2(S-2) = two Screws (S-2),
2(L-2) = two Locking Tabs (L-2)
(5): Refer to “Reference Notes.”
Reference Notes
1. Disassembly note
Slide the Rotary Tray slowly in the direction of the
front while rotating it.
2. Reassembly note
Align the rails on the Rotary Tray with the slot on
the sensor and align pin A with hole A on the
Rotary Tray.
3. Reassembly note
Re-solder the leads on the Rotary Motor Assembly
or the Detector Switch as shown in Fig. MD4.
4.
CAUTION:
Electrostatic breakdown of the laser
diode in the optical system block may occur as a
potential difference caused by electrostatic charge
accumulated on cloth, human body, etc., during
unpacking or repair work.
To avoid damage of pickup:
a. Short the three short lands of the FPC cable
with solder before removing the FFC cable
(CN5005). If you disconnect the FFC cable
(CN5005) without shorting them, the laser diode
of the pickup will be destroyed. (“View for A” in
Fig. MD5)
b. Disconnect the two connectors (CN5003 and
CN5005) on the Relay CBA.
5.
CAUTION:
When Reassembly, confirm the FFC
cable (CN5005) is connected completely. Then
remove the solder from the three short lands of the
FPC cable. (“View for A” in Fig. MD5)
6. Disassembly note
Remove the spring (P-2). Then remove the Slot
Lever with the Rotary Stopper while turning the
Slot Lever in the direction of the arrow as shown in
Fig. MD6.
7. Reassembly note
a. Install the Slot Lever and the Rotary Stopper
with spring (P-2) as shown in “Bottom View of
the Slide Tray” of Fig. MD6.
b. Align pin B on the Slot Lever with slot B on the
Motion Gear.
8. Disassembly note
The Mecha Holder Assembly and the Motion Gear
should be removed together.
9. Reassembly note
The pins, slots or holes on the Mecha Holder
Assembly, the Motion Gear and the Slide Tray align
as follows:
• Pin C on the Mecha Holder Assembly with hole B
on the Slide Tray Chassis
• Pin D on the Mecha Holder Assembly with slot C
on the Motion Gear
• Pin E on the Mecha Holder Assembly with
cavity A on the Slide Tray Chassis
• Slot A on the Mecha Holder Assembly with rib A
on the Slide Tray Chassis
