3. Reassembly note
2
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
3
(CN5005) without shorting them, the laser diode
of the pickup will be destroyed. ("View for A" in
3
Fig. MD5)
b. Disconnect the two connectors (CN5003 and
4
5
CN5005) on the Relay CBA.
6 5. CAUTION: When Reassembly, confirm the FFC
7
cable (CN5005) is connected completely. Then
6 remove the solder from the three short lands of the
7
FPC cable. ("View for A" in Fig. MD5)
