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 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 pickup 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.
NOTE ON REPLACEMENT OF DMB10 BOARD
New part of EEPROM (IC103) on the DMB10 board can not be
used. Therefore, if the mounted DMB10 board (A-1099-272-A or
A-1099-344-A or A-1115-347-A) is replaced, exchange new
EEPROM with that used before the replacement.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree 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.
Self-diagnosis Function
(When letters/numbers appear in the
display)
When the self-diagnosis function is activated to
prevent the system from malfunctioning, a 5character service number (e.g., C 13 50) with a
combination of a letter and 4 digits appears in
the on-screen display and the front panel
display. In this case, check the following table.
First 3
characters of
the service
number
C 13 The disc is dirty.
C 31 The disc is not inserted correctly.
E XX
(xx is a number)
Cause and/or corrective action
•Clean the disc with a soft cloth
(page xx).
•Restart the system, then re- insert
the disc correctly.
To prevent a malfunction, the
system has performed the selfdiagnosis function.
•Contact your nearest Sony
dealer or local authorized Sony
service facility and give the 5character service number.

2. Turn the adjustment screw and check output peaks. If the peaks
do not match for L-CH and R-CH, turn the adjustment screw
so that outputs match within 1dB of peak.

AUTO SERVO ADJUSTMENT
After parts related to the servo circuit (RF amplifier , DSP (IC102),
motor driver (IC201), EEPROM (IC103) so on) are replaced, readjusting the servo circuit is necessary.
[TEST DISC LIST]
Use the following test disc on test mode.
TDV-520CSO (DVD-SL): PART No. J-2501-236-A
LUV-P01 (CD): PART No. 4-999-032-01
TDV-540C (DVD-DL): PART No. J-2501-235-A
Note: Do not use exiting test disc for DVD.
[RFMON Level Check]
Connection:
oscilloscope
DMB10 board
CN105 pin 6 (RFMON)
CN105 pin
3
(GND)
Procedure:
1. Connect an oscilloscope to CN105 pin 6 (RFMON) and
CN105 pin 3 (GND) on the DMB10 board.
2. Turn the power on.
3. Set the test disc (DVD: TDV-520CSO, CD: LUV-P01) on the
tray and press H button to playback.
4. Confirm that oscilloscope waveform is clear and check
RFMON signal level is correct or not.
Note: A clear RFMON signal waveform means that the shape “◊” can be
clearly distinguished at the center of the waveform.
