Fig.193.2 DVD mechanism assembly section
3.2.1 Removing the Traverse mechanism assembly (See
Fig.1 to 6)
(1) Solder the short land section on the flexible wire of pickup.
(See Fig.1)
Caution:
* Solder the short land section on the flexible wire of pickup
before disconnecting the flexible wire form the connector
CN101
on the Front end board.
If the flexible wire is disconnected without attaching the
solder, the pickup may be destroyed by static electricity.
* When attaching the Traverse mechanism assembly, re-
move the solder from the short land section after connection
the flexible wire to the connector CN101
on the Front end
board.
