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
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.
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.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
This marking is located on
the rear exterior.
(Except for Korean model)
CAUTION
Use of controls or adjustments or performance of procedures
otherthan those specifiedherein may resultin hazardousradiation
exposure.

When the self-diagnosis function is activated to
prevent the system from malfunctioning, a 5-
character service number (e.g., C 13 50) with a
combination of a letter and 4 digits appears on
the screen and the front panel display. In this
case, check the following table.
Self-diagnosis Function
(When letters/numbers appear in the
display)
First 3
characters of
the service
number
Cause and/or corrective action
C 13 The disc is dirty.
,Clean the disc with a soft cloth
C 31 The disc is not inserted correctly.
,Restartthe system,then re-insert
the disc correctly.
E XX
(xx is a number) To prevent a malfunction, the
system has performed the self-
diagnosis function.
,Contact your nearest Sony
dealer or local authorized Sony
service facility and give the 5-
character service number.
Example: E 61 10
C:13:50
When displaying the version
number on the TV screen
When you turn on the system, the version
number [VER.X.XX] (X is a number) may
appear on the TV screen. Although this is not a
malfunction and for Sony service use only,
normal system operation will not be possible.
Turn off the system, and then turn on the system
again to operate.

SECTION 1
SERVICING NOTE
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 objective lens.
DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Setting Procedure :
1. Press the ?/1 button to turn the set on.
2. Press the [FUNCTION] button to set DVD function.
3. Insert a disc.
4. Press the x button and the A button simultaneously for five
seconds.
5. The message “LOCKED” is displayed and the tray is locked.
Releasing Procedure :
1. Press the x button and the A button simultaneously for five
seconds again.
2. The message “UNLOCKED” is displayed and the tray is
unlocked.
Note: When“LOCKED” is displayed,the tray lockis not releasedby turning
power on/off with the ?/1 button.
On cleaning discs, disc/lens cleaners
•Do not use cleaning discs or disc/lens cleaners
(including wet or spray types). These may cause the apparatus
to malfunction.
IMPORTANT NOTICE
Caution: This system is capable of holding a still video image or
on-screen display image on your television screen indefinitely.
If you leave the still video image or on-screen display image
displayed on your TV for an extended period of time you risk
permanent damage to your television screen.
Projection televisions are especially susceptible to this.
Attention when transported
Use this mode when returning the set to the customer after repair.
Procedure:
1. Press the ?/1 button to turn the set on.
2. Press the [FUNCTION] button to set the function “DVD”.
3. Remove all discs, and then press two buttons Hand ?/1
simultaneously.
4. After a message “MECHA LOCK” is displayed on the
fluorescent indicator tube, pull out the AC plug.
5. To exit from this mode, press the ?/1 button to turn the set
on.
Note about CDs/DVDs
The system can play CD-ROMs/CD-Rs/CDRWs recorded in the
following formats:
–audio CD format
–VIDEO CD format
–MP3 audio tracks, JPEG image files, and DivX video files of
formatconforming to ISO 9660 Level 1/Level 2,or its extended
format, Joliet
The system can play DVD-ROMs/DVD+RWs/DVD-RWs/
DVD+Rs/DVD-Rs recorded in the following formats:
–MP3 audio tracks, JPEG image files, and DivX video files of
format conforming to UDF (Universal Disc Format)
Example of discs that the system cannot play
The system cannot play the following discs:
•CD-ROMs/CD-Rs/CD-RWs other than those recorded in the
formats listed on “Note about CDs/DVDs”
•CD-ROMs recorded in PHOTO CD format
•Data part of CD-Extras
•DVDAudios
•Super Audio CD
•DATA DVDs that do not contain MP3 audio tracks, JPEG
image files, or DivX video files
•DVD-RAMs
Also, the system cannot play the following discs:
•ADVD VIDEO with a different region code
•Adisc that has a non-standard shape (e.g., card, heart)
•Adisc with paper or stickers on it
•Adisc that has the adhesive of cellophane tape or a sticker
still left on it
Notes about CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/
DVD+RW
In some cases, CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/
DVD+RW cannot be played on this system due to the recording
quality or physical condition of the disc, or the characteristics of
the recording device and authoring software.
The disc will not play if it has not been correctly finalized. For
more information, see the operating instructions for the recording
device.
Note that some playback functions may not work with some
DVD+RWs/DVD+Rs, even if they have been correctly finalized. In
this case, view the disc by normal playback.Also some DATACDs/
DATADVDs created in Packet Write format cannot be played.
