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.

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.
