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 classi­fied under the Safety of laser products, IEC
60825-1:2007, and contains a class 1M laser
module. To ensure continued safety, do not re­move 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.

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. 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. Graphically-illustrated areas become hot . Be careful not to burn yourself.

10. 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.

11. EJECT LOCK MODE for DVD mechanism

In order to change the EJECT LOCK status of the mechanism, please perform following procedure.

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.

3. BASIC ITEMS FOR SERVICE

To keep the product quality after servicing, please confirm following check points.

No. Procedures Item to be confirmed

1 Confirm whether the customer complain has

been solved.
If the customer complain occurs with the
specific media, use it for the operation check.

The customer complain must not be
reappeared.
Display, video, audio and operations must be
normal.

2 DVD Measure playback error rates at the

innermost and outermost tracks by using the
test mode with the following disc.
DVD test disc (TDV-582)

Deterioration of mecha-drive can be
checked.
The error rate must be less than the
threshold value.
(Refer to the chapter of DIAGNOSIS for the
threshold value.)

3 DVD Play back a DVD.

(Menu operation; Title/chapter search)

Display, video, audio and operations must be
normal.

4 CD Play back a CD.

(Track search)

Display, audio and operations must be
normal.

5 FM/AM tuner Check FM/AM tuner action.

(Seek, Preset)
Switch band to check both FM and AM.

Display, audio and operations must be
normal. * If the reception sensitivity is poorer
than normal, the gasket on the FM/AM tuner
unit may be damaged or lost.

6 Check whether no disc is inside the product. The media used for the operating check must

be ejected.

7 Appearance check No scratches or dirt on its appearance after

receiving it for service.

For check items concerning image and voice, please refer to the followings:

Check items concerning image Check items concerning voice

Block-noise Distortion
Crosscut noise Noise

Dot noise Low volume
Distorted image (Image skip) High volume
Low brightness Changes in level
Too bright Pause of sound
Color fading
