(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.
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.

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 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 waveform is output several times.
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)

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 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.

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.
This appliance is classified as
a CLASS 1 LASER product.
This label is located on the rear
exterior.
NOTE ON REPLACEMENT OF DMB15 BOARD
New part of EEPROM (IC103) on the DMB15 board can not be
used. Therefore, if the mounted DMB15 board (A-1174-274-A or
A-1193-178-A or A-1193-183-A or A-1193-188-A) is replaced,
exchange new EEPROM with that used before the replacement.
