SAFETY INFORMATION

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 !

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

FOR DVD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 650 nm

FOR CD :

MAXIMUM OUTPUT POWER : 7 mW

WAVELENGTH : 780 nm

Additional Laser Caution

Printing on Rear Panel

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 Q307 (650nm LD) and Q308 (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.

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.

0 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

About DualDisc playback

A DualDisc is a new two-sided disc, one side of which

contains DVD content (video, audio, etc.) while the other

side contains non-DVD content such as digital audio

material. The non-DVD, audio side of the disc is not

compliant with the CD Audio specification and therefore

may not play. The DVD side of a DualDisc plays in this

product (excluding DVD-Audio content). For more detailed
