Reference Notes
1. CAUTION 1: Locking Tabs (L-1) and (L-2) are
fragile. Be careful not to break them.
1) Release three Locking Tabs (L-1).
2) Release three Locking Tabs (L-2), then remove
the Front Assembly.
2. 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.

Screw (S-6) and lift the DVD Main CBA Unit.

destroyed. (Fig. D4)
3. CAUTION 3: When reassembling, confirm the
FFC cable (CN201) is connected completely. Then
