SECTION 1
SERVICING NOTES
The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.
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.
IMPORTANT NOTE OF PERFORMING THE OPERATION CHECK
When performing the operation check of this unit, be sure to perform the operation check after checking that it is in the following
state.
•
•
Heat sink is installed to MOTHER board
Fan motor is connected to MOTHER board
Note: If turn the power on in the state that heat sink is not installed, there is
a possibility of damage.
Also, be sure to perform the operation check in the connect the fan
motor to the MOTHER board, and the fan motor is rotating state.
If it is necessary to perform the operation check with the heat sink
removed or the fan motor removed, set the volume to 10 or less and
perform the operation check within 1 minute.

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 viscous (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.

If “PROTECTX” (X is a number) APPEARS ON THE
DISPLAY, THEN “CHECK MANUAL” FLASHES ON
THE DISPLAY.
Immediately unplug the AC

ventilation openings of the unit.
After you have checked and
found no problems, reconnect
the AC power cord (mains lead),
and turn on the system.

CAPACITOR ELECTRICAL DISCHARGE PROCESSING
When removing the MOTHER board and SMPS board after checking the operation of this unit, be sure to perform the discharge processing of C2076 on the MOTHER board and C6302 on the SMPS
board before removing the boards.
When it is removed the boards without performing the discharge
processing and it is shorted the both end of C2076 on the MOTHER board, it might be damaged the DAMP IC.
Perform the discharge processing with referring the figure below.

IMPORTANT
DESTINATION SETTING METHOD
The destination information isn’t written in the MOTHER board for
the service.
Therefore, when the MOTHER board is replaced, be sure to perform the destination setting (Important work).
Note 1: The initial setting destination of the MOTHER board for the
service is “LA”. The message “D LATIN” is displayed on the
vacuum fluorescent display.
Note 2: When distinguishing the destination of the product, refer to the
“MODEL IDENTIFICATION” on page 5.
Note 3: If destination setting isn’t performed, it is possibility to occur the
defect to each operation of this unit.
Procedure:
1. Press two buttons of the [SOUND FIELD] and [TUNING +
>] simultaneously for 3 seconds during the demonstration
mode.
2. It enters the destination setting mode, the message “D LATIN”
is displayed on the vacuum fluorescent display.
Note 4: If the message “DEST LOCK” is displayed on the vacuum
fluorescent display, press the [ ] button on the remote commander to release from this mode. Because the destination is
locked, and it cannot change the destination.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
For Schematic Diagrams.
Note:
• X : Parts extracted from the component side.
• Y : Parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
Note:
• All capacitors are in μF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specified.
• 2 : Nonflammable resistor.
• C : Panel designation.
Caution:
Pattern face side:

Parts on the pattern face side seen
from the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.
• MOTHER board is multi-layer printed board. However,
the patterns of intermediate layers have not been included in diagrams.

Note 1: Among mounted electrical parts on each board, only
parts that are described in the electrical parts list can
be replaced for repairing.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
Note 2: Among mounted parts on the MOTHER board, only
parts that are described in the electrical parts list can
be replaced for repairing.
When the parts that are not described in the electrical
parts list are defective, replace the complete mounted
board.
In this service manual, the block diagram and printed
wiring board of the MOTHER board are described
for reference.
Also, when the MOTHER board is replaced, be sure
to refer to “DESTINATION SETTING METHOD”
and “NFC OPERATION CHECKING METHOD”
on page 6.
Note 3: When the PARTY LED, SW LED, NFC and MS-476
boards are defective, replace the complete mounted
board or the whole parts including the applicable
board.
The mounted parts cannot be replaced with single for
repairing.
In this service manual, the schematic diagram and
printed wiring board of the PARTY LED, SW LED,
NFC and MS-476 boards are not described.
Also, when the NFC board is replaced, be sure to refer to “NFC OPERATION CHECKING METHOD”
on page 6.
Note 4: When the SMPS board is defective, replace the complete mounted board.
The mounted parts cannot be replaced with single for
repairing.
However, in this service manual, the block diagram,
schematic diagram and printed wiring board of the
SMPS board are described for reference.
