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.

[Important Check Points for Good Servicing]
In this manual, procedures that must be performed during repairs are marked with the below symbol.
Please be sure to confirm and follow these procedures.
1. Product safety
Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by
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.
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
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.

compatibility
This player is compatible with a wide range of disc types (media)
and formats. Playable discs will generally feature one of the following
logos on the disc and/or disc packaging. Note however that some
disc types, such as recordable CD and DVD, may be in an unplayable
format. See the Disc compatibility table below for more information.
· Also compatible with KODAK Picture CD
This player supports the IECís Super VCD standard for
superior picture quality, dual soundtracks, and widescreen
support.
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
information on the DualDisc specification, please refer to
