A1-2
The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is
received at the time of repair, a life of product may become short.
Please perform the following measure against static electricity, be careful of destruction of a
laser diode enough at the time of repair, and work.
• It works on the desk which performed measures against static electricity, such as conductive
mat.
• Soldering iron with ground wire or ceramic type is used.
• A worker needs to use a ground conductive wrist strap for body.
PREPARATION OF SERVICING
Before removing Pick Up PCB and DVD PCB connector, the short circuit the position shown in Fig. 1
using a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged.
WHEN REPLACING DVD DECK
[ When removing the DVD Deck ]
[ When installing the DVD Deck ]
Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
PCB connector.
