CABINET DISASSEMBLY INSTRUCTIONS
1. Disassembly Flowchart
This flowchart indicates the disassembly steps to gain
access to item(s) to be serviced. When reassembling,
follow the steps in reverse order. Bend, route, and
dress the cables as they were originally.
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
*=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.”
About tightening screws
When tightening screws, tighten them with the follow-
ing torque.
Reference Notes
CAUTION 1: Locking Tabs (L-1), (L-2) and (L-3) are
fragile. Be careful not to break them.
1-1. Release four Locking Tabs (L-1) and three Lock-
ing Tabs (L-2).
1-2. Release three Locking Tabs (L-3), then remove
the Front Assembly.
CAUTION 2: 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 follow next procedures.
2-1. Short the three short lands of FPC cable with sol-
der before removing the FFC cable (CN201) from
it. If you disconnect the FFC cable (CN201), the
laser diode of pickup will be destroyed. (Fig. D4)
2-2. Remove Screw (S-3A) and two Screws (S-3B).
Then disconnect Connectors (CN301), (CN401),
(CN501) and (CN601) and lift the DVD Main CBA
Unit. (Fig. D3)
CAUTION 3: When reassembling, confirm the FFC
cable (CN201) is connected completely. Then remove
the solder from the three short lands of FPC cable.
