Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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 ra-
diation exposure.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED
LINE WITH MARK 0ON 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 PUB-
LISHED BY SONY.
The following caution label is located inside the unit.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free 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 oc-
cur 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
back of the unit and will only play DVDs labeled
with identical region code.
DVDs labeled will also be played on this
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.
Discs that this system cannot
play
•CD-ROMs(except for extension “.MP3,”
“.JPG,” or “.JPEG”)
•CD-Rs/CD-RWs other than those recorded in
the following formats:

*1
ISO9660 Format
The most common international standard for the
logical format of files and folders on a CD-ROM.
There are several specification levels. In Level 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 specifications 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) make sure of the
contents of the writing software, etc.
*2
Multi Session
This is a recording method that enables adding of
data using the Track-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 session 1 and data on the tracks
in session 2.
You can play back the following discs on this
system. Other discs cannot be played back.

Notes on discs
•Thissystem 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.
•Discsrecorded on CD-R/CD-RW drives may
not be played back because of scratches, dirt,
recording condition or the driver’s
characteristics.
•CD-Rand 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 multi-
session that have not ended by “closing the
session” are not supported.
•Thesystem 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.
•Withformats other than ISO9660 level 1 and
2, folder names or file names may not be
displayed correctly.
•Thefollowing discs take a longer time to start
playback.
–adisc recorded with complicated tree
structure.
–adiscrecorded in Multi Session.
–adisc to which data can be added (non-
finalized disc).
•Some CD-Rs, CD-RWs, DVD-Rs or DVD-
RWs (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.
•Adiscrecorded in packet write format cannot
be played.
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.

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.
•Ifaudio 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.

SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveforms is output three times.
DVDTRAY LOCK MODE
•This mode let you lock the disc trays. When this mode is acti-
vated, the disc tray will not open when ZOPEN/CLOSE button
or[DISC CHANGE] button is pressed.The message “LOCKED”
will be displayed in the will be displayed on the fluorescent
indicator tube.
Procedure:
1. Press [POWER] button to turn the set ON.
2. Select DVD function.
3. Press xbutton and ZOPEN/CLOSE button simultaneously
