Notes on chip component replacement
•Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
This appliance is
classified as a CLASS 1
LASER product. This
label is located on the
rear exterior.
The following caution label is located inside the
apparatus.
Design and specifications are subject to change
without notice.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED
LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

Region code of DVDs you can
play on this system
Your system has a region code printed on the

with identical region code.
DVDs labeled will also be played on this
ALL
system.
If you try to play any other DVD, the message
“Playback prohibited by area limitations.” will
appear on the TV screen. Depending on the
DVD, no region code indication may be labeled
even though playing the DVD is prohibited by
area restrictions.

•Data part of CD-Extras
•Super Audio CDs
•Progressive JPEG format files cannot be

• DVD-RWs in VR mode (DVD-RWs created
in VR (Video Recording) mode allow the
contents to be programed or edited.)
• DVD-ROMs
• DVD Audio discs
•A DVD with a different region code.
•Audio tracks in MP3PRO format.
•A disc that has a non-standard shape (e.g.,
card, heart).
•A disc with paper or stickers on it.
•A disc that has the adhesive, cellophane tape,
or a sticker still left on it.
*1
ISO9660 Format
The most common international standard for the
logical format of files and folders on a CD-ROM.
There are severa l specification levels. In Leve l 1, file
names must be in the 8.3 format (no more than eight
characters in the name, no more than three characters
in the extension “.MP3” or “.JPG”) and in capital
letters. Folder names can be no longer than eight
characters. There can be no more than eight nested
folder levels. Level 2 sp ecifications allow file names
and folder names up to 31 characters long. Each
folder can have up to 8 trees.
For Joliet in the expansion format (file and folder
names can have up to 64 characters) m ake sure of the
contents of the writing software, etc.
*2
Multi Session
This is a recording method that enables adding of
data using the Trac k-At-Once method. Conventional
CDs begin at a CD control area called the Lead-in
and end at an area called Lead-out. A Multi Session
CD is a CD having multiple sessions, with each
segment from Lead-in to Lead-out regarded as a
single session.
CD-Extra: This format records audio (audio CD
data) on the tracks in se ssion 1 and data on the tracks
in session 2.

Note on playback operations
of DVDs and VIDEO CDs
Some playback operations of DVDs and VIDEO
CDs may be intentionally set by software
producers. Since this system plays DVDs and
VIDEO CDs according to the disc contents the
software producers designed, some playback
features may not be available. Also, refer to the
instructions supplied with the DVDs or VIDEO
CDs.
Copyrights
This product incorporates copyright protection
technology that is protected by U.S. patents and
other intellectual property rights. Use of this
copyright protection technology must be
authorized by Macrovision, and is intended for
home and other limited viewing uses only unless
otherwise authorized by Macrovision. Reverse
engineering or disassembly is prohibited.
Music discs encoded with
copyright prot ec ti on
technologies
This product is designed to playback discs that
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with
copyright protection technologies are marketed
by some record companies. Please be aware that
among those discs, there are some that do not
conform to the CD standard and may not be
playable by this product.
Cautions when playing a disc
that is recorded in Multi
Session
•This system can play Multi Session CDs when
an MP3 audio track is contained in the first
session. Any subsequent MP3 audio tracks
recorded in later sessions can also be played
back.
•This system can play Multi Session CDs when
a JPEG image file is contained in the first
session. Any subsequent JPEG image files
recorded in later sessions can also be played
back.
•If audio tracks and images in music CD
format or video CD format are recorded in the
first session, only the first session will be
played back.
Notes on discs
•This system can play CD-R/CD-RW discs
edited by the user. However, note that
playback of some discs may not be possible
depending on the recording device used for
recording or the disc condition.
•Discs recorded on CD-R/CD-RW drives may
not be played back because of scratches, dirt,
recording condition or the driver’s
characteristics.
•CD-R and CD-RW discs that have not been
correctly finalized (processing to allow play
by a normal CD player) cannot be played.
•CD-R and CD-RW discs recorded in multisession that have not ended by “closing the
session” are not supported.
•The system may be unable to play MP3/JPEG
format files that do not have the extender
“.MP3,” “.JPG,” or “.JPEG.”
•Attempting to play non-MP3/JPEG format
files that have the extender “.MP3,” “.JPG,”
or “.JPEG” may result in noise or
malfunction. Playback is possible up to 8
levels.
•With formats other than ISO9660 level 1 and
2, folder names or file names may not be
displayed correctly.
•The following discs take a longer time to start
playback:
–a disc recorded with a complicated tree
structure.
–a disc recorded in Multi Session.
–a disc to which data can be added (non-
finalized disc).
•Some CD-Rs, CD-RWs, DVD-Rs or DVDRWs (in video mode) (DVD-RWs created in
video mode have the same format as a DVD
VIDEO) cannot be played on this system
depending upon the recording quality or
physical condition of the disc, or the
characteristics of the recording device.
Furthermore, the disc will not play if it has not
been correctly finalized. For more
information, see the operating instructions for
the recording device.
•A disc recorded in packet write format cannot
be played.

SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objectiv e lens.
RELEASING THE DISC LOCK
The disc lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure :
While pressing the [ENTER] key , press the Z key for 5 seconds.
The message “UNLOCKED” is displayed and the disc is unlocked.
Note: When “LOCKED” is displayed, the disc lock is not released by
turning power on/off with the I/1 key.
