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:

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 safety 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 safety, you should not risk trying to do so
and refer the repair to a qualified service technician.

CAUTION

Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacture.
Discord used batteries according to the manufacture's instructions.

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.

CAUTION
CLASS 1M INVISIBLE LASER RADIATION WHEN OPEN. DO NOT VIEW DIRECTLY WITH OPTICAL INSTRUMENTS

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.

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)

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.

following the safety instructions described in this manual.

1 Use specified parts for repair.

Use genuine parts. Be sure to use important parts for safety.

2 Do not perform modifications without proper instructions.

Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as
radio/TV interference and foreign noise.

3 Make sure the soldering of repaired locations is properly performed.

When you solder while repairing, please be sure that there are no cold solder and other debris.
Soldering should be finished with the proper quantity. (Refer to the example)

4 Make sure the screws are tightly fastened.

Please be sure that all screws are fastened, and that there are no loose screws.

5 Make sure each connectors are correctly inserted.

Please be sure that all connectors are inserted, and that there are no imperfect insertion.

6 Make sure the wiring cables are set to their original state.

Please replace the wiring and cables to the original state after repairs.
In addition, be sure that there are no pinched wires, etc.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.

a Safe environment should be secured during servicing.

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.

2. Adjustments

To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.

4. Cleaning

For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.

3. Lubricants, Glues, and Replacement parts

Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.

5. Shipping mode and Shipping screws

To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

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. 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.

4. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY" .

5. After replacing the pickup unit, be sure to skew adjustment.

6. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector
is plugged or unplugged.

7. ICs (IC1011, 1021) and the heat sink becomes hot areas. Be careful not be burn yourself.

8. Mechanism cover(Sheet : CNN2525) is NOT reusable. If you removed it, please replace it with the new one.

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.

Handling guideline of discs
and player

• Use only discs featuring any of following
logos.

DVD video

Video CD

CD

• Use only normal, round discs. If you insert
irregular, non-round, shaped discs they
may jam in the DVD player or not play prop­erly.

• Check all discs for cracks, scratches or
warping before playing. Discs that have
cracks, scratches or are warped may not
play properly. Do not use such discs.

• Avoid touching the recorded (non-printed)
surface when handling the disc.

• Store discs in their cases when not in use.

• Keep discs out of direct sunlight and do
not expose the discs to high temperatures.

• Do not attach labels, write on or apply che­micals to the surface of the discs.

• To clean a disc, wipe the disc with a soft
cloth outward from the center.

• If the heater is used in cold weather, con­densation may form on components inside
the DVD player. Condensation may cause
the DVD player to not operate properly. If
you think that condensation is a problem
turn off the DVD player for an hour or so to
allow it to dry out and wipe any damp discs
with a soft cloth to remove the moisture.

• Road shocks may interrupt disc
playback.
