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 Q307 (650nm LD) and Q308 (780nm LD)
on the DVD MAIN 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.
