SAFETY INFORMATION
Where in a manufacturer’s service documentation, for example in circuit diagrams or lists
of components, a symbol is used to indicate that a specific component shall be replaced only
by the component specified in that documentation for safety reasons, the following symbol shall
be used:
CAUTION:
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
-Safety Precautions for those who Service this Unit.
When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable
results.
Caution:
1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept.
2. During repair or tests, do not view laser beam for 10 seconds or longer.
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.
CAUTION
This product is a class 1 laser product classi-
fied under the Safety of laser products, IEC
60825-1:2007, and contains a class 1M laser
module. To ensure continued safety, do not re-
move any covers or attempt to gain access to
the inside of the product. Refer all servicing to
qualified personnel.
CAUTION—CLASS 1M INVISIBLE LASER
RADIATION WHEN OPEN, DO NOT VIEW
DIRECTLY WITH OPTICAL INSTRUMENTS.
CAUTION
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
This product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive
harm.

Additional Laser Caution
Transistors Q1103 and Q1104 in PCB drive the laser diodes for DVD and CD
respectively. When Q1103 or Q1104 is shorted between their terminals,
the laser diodes for DVD or CD will radiate beam. If the top cover is removed
with no disc loaded while such short-circuit is continued, the naked eyes may
be exposed to the laser beam.
Laser diode characteristics
Wave length:
DVD:660 nm to 670 nm
CD:780 nm to 800 nm
Focus lens on Maximum output:
CD:6.26 mW(Emitting period :9 sec.)
DVD:1.27 mW (Emitting period : unlimited)
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacturer.
Discord used batteries according to the manufacturer's instructions.

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
1. You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and
should keep the safety during servicing by following the safety instructions described in this manual.
2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
3. Please be sure to conduct line process to original status if you make assembling after repair.
4. Please be careful of not to imply static charge onto integrated circuits, etc, when you conduct repair work.
Especially, please use soldering iron with its tip grounded.
Also, please use a pair of tweezers with static charge protection capability if there is the possibility of contacting to
device terminals, and avoid the use of metal-made tweezers.
5. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on
mode may damage the ICs inside the unit.
6. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder)
by referring to "the DISASSEMBLY".
7. Please keep the distance of more than 13 cm from focus lens for safety when you check pickup and make adjustment,
and do not look straight at Laser Beam for more than 10 seconds.
8. Please power adjustment when you replaced mechanical area of DVD Mecha Module or DVD core unit.
9. On this mechanism, Pickup and Spindle Motor can not be replaced at the service site, because a special facility is
required for the adjustment after replacing them.
So, if Pickup or Spindle Motor is defective, replace the Mechanism Unit.
10. The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.

1.2 NOTES ON SOLDERING
2. SPECIFICATIONS
2.1 SPECIFICATIONS
2.2 DISC/CONTENT FORMAT
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 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C 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.
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.
For all items except the backup current, refer to the Owner's Manual.
Backup current......................... 5.0 mA or less

*1. INDP7, 8 are set by terminal resistor common to main source and mixing source (simultaneous use is also available).
*2. INMPN and INMN are input dedicated to mixing. If differential is received by ISOLATOR, they become negative input of INDP8.
*3. At single input, receipt of 8ch by ISOLATOR becomes 4CH.
*4. Digital Audio Input can be also set to output depending on setting of resistor.
