SECTION 1
PRECAUTION
1.1Safety Precautions
(1) This design of this product contains special hardware and
many circuits and components specially for safety purposes. For continued protection, no changes should be made
to the original design unless authorized in writing by the
manufacturer. Replacement parts must be identical to
those used in the original circuits. Services should be performed by qualified personnel only.
(2) Alterations of the design or circuitry of the product should
not be made. Any design alterations of the product should
not be made. Any design alterations or additions will void
the manufacturers warranty and will further relieve the
manufacture of responsibility for personal injury or property
damage resulting therefrom.
(3) Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special
safety characteristics are identified in the Parts List of Service Manual. Electrical components having such features
are identified by shading on the schematics and by ( ) on
the Parts List in the Service Manual. The use of a substitute
replacement which does not have the same safety characteristics as the recommended replacement parts shown in
the Parts List of Service Manual may create shock, fire, or
other hazards.
(4) The leads in the products are routed and dressed with ties,
clamps, tubings, barriers and the like to be separated from
live parts, high temperature parts, moving parts and/or
sharp edges for the prevention of electric shock and fire
hazard. When service is required, the original lead routing
and dress should be observed, and it should be confirmed
that they have been returned to normal, after reassembling.
(5) Leakage shock hazard testing
After reassembling the product, always perform an isolation check on the exposed metal parts of the product (antenna terminals, knobs, metal cabinet, screw heads,
headphone jack, control shafts, etc.) to be sure the product
is safe to operate without danger of electrical shock.Do not
use a line isolation transformer during this check.
• Plug the AC line cord directly into the AC outlet. Using a
"Leakage Current Tester", measure the leakage current
from each exposed metal parts of the cabinet, particularly any exposed metal part having a return path to the
chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.).
• Alternate check method
Plug the AC line cord directly into the AC outlet. Use an
AC voltmeter having, 1,000Ω per volt or more sensitivity
in the following manner. Connect a 1,500Ω 10W resistor
paralleled by a 0.15µF AC-type capacitor between an ex-
posed metal part and a known good earth ground.
Measure the AC voltage across the resistor with the AC
voltmeter.
Move the resistor connection to each exposed metal
part, particularly any exposed metal part having a return
path to the chassis, and measure the AC voltage across
the resistor. Now, reverse the plug in the AC outlet and
repeat each measurement. Voltage measured any must
not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5
mA AC (r.m.s.).

1.2Warning
(1) This equipment has been designed and manufactured to
meet international safety standards.
(2) It is the legal responsibility of the repairer to ensure that
these safety standards are maintained.
(3) Repairs must be made in accordance with the relevant
safety standards.
(4) It is essential that safety critical components are replaced
by approved parts.
(5) If mains voltage selector is provided, check setting for local
voltage.
1.3Caution
Burrs formed during molding may be left over on some parts
of the chassis.
Therefore, pay attention to such burrs in the case of preforming repair of this system.
1.4Critical parts for safety
In regard with component parts appearing on the silk-screen
printed side (parts side) of the PWB diagrams, the parts that are
printed over with black such as the resistor ( ), diode ( )
and ICP ( ) or identified by the " " mark nearby are critical
for safety. When replacing them, be sure to use the parts of the
same type and rating as specified by the manufacturer.
(This regulation dose not Except the J and C version)
1.5Remote control
The Lithium battery is in danger of explosion if replaced incorrectly. Replace it only with the same or equivalent type.

1.6Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser
diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.6.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products.
Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the
traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(caption)
Anti-static wrist strap
1M
Conductive material
(conductive sheet) or iron plate
(3) Handling the optical pickup
• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical
pickup are shorted. After replacement, return the shorted parts to their original condition.
(Refer to the text.)
• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily
destroy the laser diode.
1.7Handling the traverse unit (optical pickup)
(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.
(2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the
replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a
time when attaching it to the connector.
(3) Handle the flexible cable carefully as it may break when subjected to strong force.
(4) I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.
1.8Attention when traverse unit is decomposed
*Please refer to "Disassembly method" in the text for the pickup unit.
• Apply solder to the short land sections before the card wire is disconnected from the connector on the servo board. (If the card wire
is disconnected without applying solder, the pickup may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land sections after connecting the card wire.

4.4.2 DC Offset detection circuit design
•Purpose:
To prevent breakdown, when occur DC offset between speaker output "+" and "-".
• Target:
Detect DC offset, then stop the Power Amp operation and shift
to specified condition.
4.4.3 Possible causes of DC offset at speaker output lines
(1) Mis-connection for Speaker output for example touch to car
body or battery line.
(2) Current leak of coupling capacitor for Power IC input.
(3) Current leak of AC-GND capacitor for Power IC AC-GND.
(4) Capacitor shorted of above parts due to foreign object.

4.4.4 Type of checking
4.4.4.1To detect DC Offset Error
• Mis-connection
- Short any one speaker out line to GND or Vcc
• Capacitor leak
- Parallel 330kΩ to either any one of coupling cap or AC-GND
capacitor (to simulate current leakage of capacitor)
- Shorted either any one of coupling capacitor or AC-GND capacitor.

4.4.6 Manipulate after detect DC Offset
• If detected error 10 consecutive times, and 10th error occurred
in "Mis-connect detection period", judge as "Mis-connect".
• If detected error 10 consecutive times, and 10th error occurred
in "Capacitor leak detection period", judge as "Capacitor leak ".
• If detected error 10 consecutive times, and 10th error occurred
in "Other detection period" and detected another 10 errors consecutively, then judge as "Other".
• If judge as "Mis-connect".
- turn off speaker output.
- - display "MISWIRING", check wiring connection then reset.
- key access disable except button of Eject, Reset and service
mode
- record error in EEPROM "DC1 ERR"
- the product is able to be recovered by Reset button.
• If judge as "Capacitor leak ".
- turn off speaker output.
- display "WIRING", check wiring connection then reset.
- key access disable except button of Eject, Reset and service
mode
- record error in EEPROM "DC2 #" (# means counter number)
- the product can be recovered by pressing the Reset button
before the capacitor leak error counter reach "DC2 4".
After that, only clear the counter back to "0" can recover the
product.
• If judge as "Other" (manipulation same as mis-connect)
SECTION 5
TROUBLESHOOTING
5.1How to cancel DC offset error
Check to be sure the terminals of the speaker leads are covered with insulating tape properly, then reset the product.
If an error message does not disappear even after a reset, there is a need for internal repair.
5.2How to clear DC offset error recorded in EEPROM
Refer to “4.3 DC error information mode”.

PRECAUTIONS ON SERVICE
Certain parts of the power circuits and the GNDs differ according to the models. Care must be
taken for the following points as the differences are indicated separately in the LIVE GND () and
the ISOLATED (NEUTRAL) GND ().
1.Do not touch the LIVE GND, or do not touch the LIVE GND and the ISOLATED (NEUTRAL)
GND at the same time. It may cause an electric shock.
Before pulling out the chassis or other parts, make sure to pull out the power cord from the
wall outlet first.
2.Do not short circuit between the LIVE GND and ISOLATED (NEUTRAL) GND, or never
measure the LIVE GND and ISOLATED (NEUTRAL) GND at the same time using measuring
instruments (oscilloscope, etc.). It may blow fuses or damage other parts.
