SECTION 1

PRECAUTION

1.1 Safety 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.

1.2 Warning

(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.

1.3 Caution

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.

1.4 Critical 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)

1.5 Remote control

The Lithium battery is in danger of explosion if replaced incorrectly. Replace it only with the same or equivalent type.

1.6 Preventing 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

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.

(No.MA596<Rev.005>)5/28

1.7 Handling 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 ad-

justs the laser power. Do not turn it.

1.9 Important for laser products

1.8 Attention 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.

4.9 DC Offset error description

4.9.1 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.

4.9.2 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.

• 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

4.9.3 Type of checking

4.9.3.1 To 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.

5.1 How 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.
