  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.

CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
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 of the unit.

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.
DISC SLOT LOCK
The disc slot 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  
stick and the  
 button simultaneously for five
seconds.
5. The message “LOCKED” is displayed and the slot is locked.
Releasing Procedure :
1. Press the  
x  
stick and the  
 button simultaneously for five
seconds again.
2. The message “UNLOCKED” is displayed and the slot is
unlocked.
Note:
When “LOCKED” is displayed, the slot lock is not released by
turning power on/off with the  ?/1  button.
Note on DMB12 board replacement
New part of EEP ROM (IC103, IC706) on the DMB12 board cannot
be used. Therefore, if the mounted DMB12 board (A-1166-958-A,
etc.) is replaced, exchange new EEP ROM (IC103, IC706) with
that used before the replacement.
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.
When displaying the version 
number on the screen
When you turn on the system, the version 
number [VER.X.XX] (X is a number) may 
appear on the 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.
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.
,Restart the 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
VER.X.XX
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.
