SAFETY INFORMATION

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.

AQualified 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.

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:

B

-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.

Caution:

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

CSPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

CAUTION

This product is a class 1 laser product classified under the Safety of laser products, IEC 60825-1:2007.

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
				Wave length : 785 nm to 814 nm
				Maximum output : 1 190 µW(Emitting period : unlimited)
E
					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.

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.

1.2 NOTES ON SOLDERING

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

E

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).

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

Parts numbers of lead-free solder:

5.2 ERROR CODE LIST

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

Acause 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 head unit

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.

ENOTES

•Indications of error codes are available only during disc operations, because CD operations are unavailable if a mechanical error is generated.

•If the TOC cannot be read, It stops because of error 07.

•If you design a new head unit, be sure to use one of the display formats indicated in “Display example of the head unit.”

•The 2 high-order digits of an error code denote the main classification, shown below.

Result of rewriting

(1)	Rewriting succeeded	Displayed when USB rewriting is normally terminated.
		In 5 seconds, usual operation (OFF SOURCE) is started.
(2)	Upgrading file error	Displayed when there is no upgrading file in USB memory or the data of upgrading file is different.
	Upgrading file is not detected	In 5 seconds, usual operation (OFF SOURCE) is started.
		If the upgrading file error is detected or the upgrading file is not detected after the rewriting is retried, the rewriting is failed.
		In 5 seconds, rewriting is retried.
(3)	Rewriting failed	Displayed when the writing of upgrading file in serial Flash is not normally terminated.
		Or, displayed if the upgrading file error is detected or the upgrading file is not detected after the rewriting is retried.
		In 5 seconds, rewriting is retried.
(4)	Retry count over	Displayed when the retry becomes unavailable because the retry count is exceeded.
		The display is continued until the power supply is turned OFF. If the power supply is turned ON again, the display is not changed.		F
		The upgrading using USB is disabled, so it is necessary to write programs in serial Flash using E10A.

After the [EJECT] key is pressed keys other than the [EJECT] key should not be pressed, until disc ejection is complete.

When the key [2] or [3] is pressed during the Focus Search, the power supply should be immediately turned off (otherwise the lens sticks to Wall, causing the actuator to be damaged).

In the case of 100TR Jump, the mechanism shall be set to the Tracking Close mode when the key is released.

F When the power is turned on/off the gain of the RFAMP is reset to 0 dB. At the same time all the self-adjusting values shall return to the default setting.

Do not do Tracking Servo Close before doing Focus Servo Close. (Because the overcurrent flows)
