Reference Notes
CAUTION 1: Locking Tabs (L-1) are fragile. Be careful
not to break them.
1-1.Connect the wall plug to an AC outlet and press the
OPEN/CLOSE button to open the Tray.
1-2.First, remove the Tray Panel by releasing two Lock-
ing Tabs (L-1). Second, release two Locking Tabs
(L-2). Then, release five Locking Tabs (L-3) (to do
this, first release three Locking Tabs (A) at the
bottom, and then two Locking Tabs (B) at the side.)
(Fig. 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.
2-1.Slide out the pickup unit as shown in Fig. 5.
2-2.Short the copper pattern (half-moon shape) of FPC
cable with solder before removing the FFC cable
(CN001) from it. If you disconnect the FFC cable
(CN001), the laser diode of pickup will be destroyed.
(Fig. 5)
2-3.Disconnect Connector (CN201). Remove two
Screws (S-3) and lift the DVD Mecha. (Fig. 4)
CAUTION 3: When reassembling, confirm the FFC
cable (CN001) is connected completely. Then remove
the solder from copper pattern (half-moon shape) of
FPC cable. (Fig. 5)
