SAFETY INFORMATION
CAUTION
A
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.
B
Health & Safety Code Section 25249.6 - Proposition 65
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:
- 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.
C
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.
CAUTION:
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
CAUTION
D 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

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
Wave length:
DVD:660 nm to 670 nm B
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)
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 C
with no disc loaded while such short-circuit is continued, the naked eyes may
be exposed to the laser beam.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer's instructions.

1. SERVICE PRECAUTIONS
1.1 SAFETY PRECAUTIONS
You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and
A should keep the safety during servicing by following the safety instructions described in this manual.
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.
1.2 NOTES ON DISASSEMBLY / ASSEMBLY
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.
To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder)
by referring to CRT5651 "3.4 HOW TO REMOVE AND INSTALL THE DVD CORE UNIT".
B
Please be sure to conduct line process to original status if you make assembling after repair.
1.3 NOTES ON OPERATION CHECK / DIAGNOSIS
EJECT LOCK MODE for DVD mechanism
< Procedure >
To enter EJECT LOCK MODE : Reset start while pressing [EJECT] key and [TRACK UP] key.
To exit EJECT LOCK MODE : Follow the same steps to enter this mode.
When a home product is used in a vehicle (using DC/AC converter), GND on secondary side of some devices of home
products (PS etc.) becomes indefinite. If these devices are connected to the unit, GND becomes indefinite because
C ISO is received and the video disordered.
If a defect is generated in a market, the land is prepared between GNDs for connecting GND of the unit sides and
VGND of input as a service.
With this product, a part of VGND pattern is thin. If it is used, insert 0.5A of fuse.
A used part and wiring numbers are shown below.
Wiring number: P2204, P2205
Used part: CEK1379 or CEK1278
1.4 NOTES ON REPLACING PARTS
Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
D
Please be careful of not to apply 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.
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.

F
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 DVD Mechanism Module.
