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

trainedto 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 mayvoid the warranty. If you are not qualified to perform the repair of this product properly and

safely, youshould 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

LASER DIODE CHARACTERISTICS

FOR MD : MAXIMUM OUTPUT POWER : 41mW

WAVELENGTH: 780 - 800 nm

Additional Laser Caution

for DVD

: See page 79.

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 (XCLOSE) side (OPEN signal is

0V and XCLOSE signal is 3.5V), a laser becomes the status which

can completely oscillate.

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 Q101 (650nm LD) and Q102 (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.

Additional Laser Caution

for MD

Control method of the current through a laser diode.

The resistor R166 on the MD MOUNT ASSY (For MD mechanism

assembly) are for the limiting of current through a laser diode.

Control method of the laser output power

The laser pick-up assembly provide the photo-diodes and APC (Auto

Power Control) circuit.

The photo-diode detect output of the laser diode then IC201 control the

APC circuit according to the signal voltage of the photo-diode via IC101.

Laser Interlock Switch

The loading position detect switch is set to " LOAD ON " position, IC201

get the " LOAD " signal, and hand the laser " LDON " signal to APC (Auto

Power Control) circuit of the Laser pick-up assembly.

Then a laser diode can be lighted when the " LOAD " signal is " LOAD

ON " position.

[ Important symbols for good services ]

In this manual, the symbols shown-below indicate that adjustments, settings or cleaning should be made securely.

When you find the procedures bearing any of the symbols, be sure to fulfill them:

2. Adjustments

To keep the original performances of the product, optimum adjustments or specification confirmation is indispensable.

In accordance with the procedures or instructions described in this manual, adjustments should be performed.

3. Cleaning

For optical pickups, tape-deck heads, lenses and mirrors used in projection monitors, and other parts requiring cleaning,

proper cleaning should be performed to restore their performances.

5. Lubricants, glues, and replacement parts

Appropriately applying grease or glue can maintain the product performances. But improper lubrication or applying

glue may lead to failures or troubles in the product. By following the instructions in this manual, be sure to apply the

prescribed grease or glue to proper portions by the appropriate amount.For replacement parts or tools, the prescribed

ones should be used.

4. Shipping mode and shipping screws

To protect the product from damages or failures that may be caused during transit, the shipping mode should be set or

the shipping screws should be installed before shipping out in accordance with this manual, if necessary.

1. Product safety

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.

General disc compatibility

This player was designed and engineered to

be compatible with software bearing one or

more of the following logos:

· KODAK Picture CD

is a trademark of Fuji Photo Film Co.

Ltd.

This player supports the IEC's Super VCD

standard. Compared to the Video CD stan-

dard, Super VCD offers superior picture

quality, and allows two stereo soundtracks to

be recorded. Super VCD also supports the

widescreen size.

Other formats, including but not limited to the

following, are not playable in this player:

DVD-Audio / SACD / DVD-RAM

DVD-ROM / CD-ROM*

DVD-R/RW and CD-R/RW discs (Audio CDs

and Video CD/Super VCDs) recorded using a

DVD recorder, CD recorder or personal

computer may not be playable on this unit.

This may be caused by a number of possibili-

ties, including but not limited to: the type of

disc used; the type of recording; damage, dirt

or condensation on either the disc or the

player's pick-up lens. See Disc Compatibility

on page 9 for notes about particular software

and formats.

Disc Compatibility

CD-R/RW compatibility

· This unit will play CD-R and CD-RW discs

recorded in CD Audio or Video CD/Super

VCD format, or as a CD-ROM containing

WMA, MP3 or JPEG files. However, any

other content may cause the disc not to

play, or create noise/distortion in the

output.

· This unit cannot record CD-R or CD-RW

discs.

· Unfinalized CD-R/RW discs recorded as

CD Audio can be played, but the full Table

of Contents (playing time, etc.) will not be

displayed.

DVD-R/RW compatibility

· This unit will play DVD-R/RW discs

recorded using the DVD-Video format that

have been finalized using a DVD-recorder.

· This unit will play DVD-RW discs recorded

using the Video Recording (VR) format.

· DVD-RW shows in the display when a VR

format DVD-RW disc is loading.
