SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-

it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been

trained to 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

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

WAVELENGTH : 650 nm

FOR CD :

MAXIMUM OUTPUT POWER : 7 mW

WAVELENGTH : 780 nm

Additional Laser Caution

1. Laser Interlock Mechanism

· Loading switch (S101 on the LOAB Assy) is used for interlock

mechanism of the laser.

When this switch turned ON in SW2 (CLOSE) side (OPEN signal is

0V and CLOSE signal is 3.5V), a laser becomes the status which can

completely oscillation.

Furthermore, the laser completely oscillates in the disc judgment and

disc playback.

When player is power ON state and laser diode is not completely

oscillating, 780nm laser diode is always oscillating by half power.

· Laser diode is driving with Q201 (650nm LD) and Q211 (780nm LD)

on the DVDM 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.

The interlock mechanism mentioned above becomes invalid in this

mode.

2. When the cover is open, close viewing through the objective lens with

the naked eye will cause exposure to the laser beam.
