SAFETY INFORMATION

A

This service manual is intended for qualified service technicians ; it is not meant for the casual do­it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been
trainedto properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and
may void the warranty. If you are not qualified to perform the repair of this product properly and
safely, you should not risk trying to do so and refer the repair to a qualified service technician.

WARNING !

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1

B

BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR
CLASS 1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

LASER DIODE CHARACTERISTICS

FOR DVD : MAXIMUM OUTPUT POWER : 5 mW

FOR CD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 650 nm

WAVELENGTH : 780 nm

(Printed on the Rear Panel)

Additional Laser Caution

1.

• Laser diode is driving with Q2303,Q2305(650nm LD) and Q2302,
Q2304(780nm LD)on the DVD MT PCB Assy.
Therefore, when short-circuit between the emitter and collector of these
transistors or the base voltage is supplied for transistors turn on, the
laser oscillates. (failure mode)

• In the test mode ∗ , there is the mode that the laser oscillates except
for the disc judgment and playback. LD ON mode in the test mode
oscillates with the laser forcibly.

2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.

1. SERVICE PRECAUTIONS

1.1 NOTES ON SOLDERING

NOTES ON SOLDERING

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

1.2 WHEN REPLACING DVD DECK

WHEN REPLACING DVD DECK

A

B

C

[ Removing the DVD Deck ]

Before removing Pick Up PCB and DVD PCB connector, 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.

[ Installing the DVD Deck ]

Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
PCB connector.

NOTE

•

Before your operation, please read “PREPARATION OF SERVICING” .

•

Use the Lead Free solder.

•

Manual soldering conditions

• Soldering temperature: 320 ± 20˚C

• Soldering time: Within 3 seconds

• Soldering combination: Sn-3.0Ag-0.5Cu

•

When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the
Flux smoke from it.

Short circuit using a
soldering iron.

PREPARATION OF SERVICING

E

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, the life of the product may be shortened.
Please perform the following measure against static electricity, be careful of destruction of a
laser diode at the time of repair.

• Place the unit on a workstation equipped to protect 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.
