SAFETY INFORMATION

CAUTION

AThis service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual.

Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

WARNING

This product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive harm.

Health & Safety Code Section 25249.6 - Proposition 65

B

Where in a manufacturer’s service documentation, for example in circuit diagrams or lists

of components, a symbol is used to indicate that a specific component shall be replaced only by the component specified in that documentation for safety reasons, the following symbol shall be used:

-Safety Precautions for those who Service this Unit.

When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results.

CCaution:

1.During repair or tests, minimum distance of 13 cm from the focus lens must be kept.

2.During repair or tests, do not view laser beam for 10 seconds or longer.

CAUTION:

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

CAUTION

CLASS 1M INVISIBLE LASER RADIATION WHEN OPEN. DO NOT VIEW DIRECTLY WITH OPTICAL INSTRUMENTS

D

WARNING!

The AEL (accessible emission level )of the laser power output is less than CLASS 1 but the laser component is capable of emitting radiation exceeding the limit for CLASS 1.

A specially instructed person should do servicing operation of the apparatus.

Laser diode characteristics

EWave length : 785 nm to 814 nm

Maximum output : 1 190 µW(Emitting period : unlimited)

Additional Laser Caution

Transistors Q101 in PCB drive the laser diodes.

When Q101 is shorted between their terminals, the laser diodes will radiate beam. If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam.

							Use grease and adhesives that are equal to the specified substance.	E
							Make sure the proper amount is applied.
4. Cleaning
							For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
							cleaning should be performed to restore their performances.
5. Shipping mode and Shipping screws
							To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
							installed before shipment. Please be sure to follow this method especially if it is specified in this manual.	F

1. SERVICE PRECAUTIONS

1.1 SERVICE PRECAUTIONS

A

1.You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual.

2.Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on mode may damage the ICs inside the unit.

3.To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder) by referring to "the DISASSEMBLY".

4.After replacing the pickup unit, be sure to check the grating.

5.Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by

electrostatic induction.

6. On CD Core Unit, actual cable colors and silk print are different.

Green Red

White Black

7.When a CD-DA (regular music CD) is played in the CD test mode, its sound quality will be temporarily deteriorated. The CD will then repeat normal, deteriorated, normal… playback.

This is due to the difference in the playback modes between the normal operation mode and the CD test mode, and the interval of generating deteriorated mode and the time taken to return to the normal mode depend on the error of each clock.

The time taken to turn to the deteriorated mode is at a minimum around 20 seconds while the time to return to the normal mode is maximum 40 seconds approximately.

Make sure to check the sound quality in the normal operation mode.

8. area and a heat sink becomes hot areas. Be careful not to burn yourself.

1.2 NOTES ON SOLDERING

A

For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.

Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering.

Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting

temperatures (hard to melt/easy to harden).

B

The following lead-free solders are available as service parts:

Parts numbers of lead-free solder:

GYP1006 1.0 in dia.

GYP1007 0.6 in dia.

GYP1008 0.3 in dia.

5.2 ERROR CODE LIST

A ERROR CODES

If a CD memory device is inoperable, or operation of such media is stopped by an error, the error mode is established and a cause of the error is displayed by an error code. Indication of error codes is intended to reduce the number of calls from customers and facilitate failure analysis and repair work in servicing.

(1) DISPLAY METHOD

If “0xFD” error mode is displayed in CD MODE (CD MODE area for display), an error code will be displayed in the MIN (minute display) and SEC (second display) areas.

The same code is displayed in the MIN and SEC areas. The TNO area is blank (#0FFH), as it conventionally was.

• Display example of the main unit

B

Depending on the display capability of LCDs, the display format varies, as shown below. XX denotes an error number. Note: In a case of an OEM product, the error display format is subject to the specifications used by the equipment

manufacturer.

NOTES
