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 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.
SAFETY-RELATED  COMPONET  WARNING!
COMPONENTS  IDENTIFIED  BY  MARK  0  OR  DOTTED  LINE  
WITH  MARK

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.
CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.
This appliance is classified as a CLASS 1 
LASER product. This marking is located 
on the rear exterior.
Self-diagnosis Function
(When letters/numbers appear in the
display)
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 TV screen and the front
panel display. In this case, check the
following table.
First 3
characters of 
the service
number
Cause and corrective
action
C 13
• Clean the disc with a 
soft cloth.
C 31
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
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
the system, and then turn on the system
again to operate.

SECTION  1
SERVICING  NOTES
NOTES  ON  HANDLING  THE OPTICAL  PICK-UP  
BLOCK  OR  BASE  UNIT
The laser diode in the optical pick-up block may suffer electrostat-
ic 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 fl exible 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 refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.
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 viscous (sticky, less prone to fl ow) 
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.
RELEASING  THE  DISC  ANTITHEFT
The disc lock function for the antitheft of an demonstration disc in 
the store is equipped.
Releasing Procedure:
1.  Press the [
?/1
] button to turn on the system.
2.  Press the [
DVD N
] button to select the “DVD”.
3.  While pressing the [
x
] button, press the [
Z
] button until 
“UNLOCKED” displayed on the fl uorescent indicator tube 
(around 5 seconds).
Note: When “LOCKED” is displayed, the disc lock is not released by 
turning power on/off with the [
?/1
] button.
NOTES  ON  REPLACEMENT  OF  THE  DMB15  BOARD
IC103 on the DMB15 board cannot exchange with single. When 
this part is damaged, exchange the entire mounted board.
