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 mayvoid the warranty. If you are not qualified to perform the repair of this product properly and
safely, youshould 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

B

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 : 5 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 Q7 (650nm LD) and Q8 (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.

7 Note on replacing the Front Panel Assy (for the LFXJ type only)

The Front Panel Assy-S (VXX2919) is designed for both the LFXJ type (Taiwanese model) and the U.S.A. model, and is provided with a
Sensormatic seal to activate shoplifting alarms. This Sensormatic seal (VAN1004) is not necessary for the LFXJ type, and is not originally
provided with the product.

D

Therefore, before replacing the Front Panel Assy-S for the LFXJ type, remove the Sensormatic seal, as shown below.

Note: If the Front Panel Assy-S is replaced without its Sensormatic seal removed, the product may trigger a shoplifting alarm at a store,
etc.

Procedures:

1. Cut off the two pins that secure the main key (5/5), using nippers, etc.

2. Remove the main key (5/5) and remove the Sensormatic seal.

Cut off these pins.
