SAFETY INFORMATION

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.

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:
	C		USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
			SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
			CAUTION
			This product is a class 1 laser product classi-
			fied under the Safety of laser products, IEC
			60825-1:2007, and contains a class 1M laser
			module. To ensure continued safety, do not re-
			move any covers or attempt to gain access to
			the inside of the product. Refer all servicing to
			qualified personnel.
	D
			CAUTION—CLASS 1M INVISIBLE LASER
			RADIATION WHEN OPEN, DO NOT VIEW
			DIRECTLY WITH OPTICAL INSTRUMENTS.

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

ECLASS 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)

Additional Laser Caution

Transistors Q101 in PCB drive the laser diodes.

FWhen 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.

E	8. How to Handle Infrared Deteching unit for Remote Control of Grille
	The infrared deteching unit for remote control of keyboard unit is not fixed with cushion, etc.
	When external force is applied on the infrared deteching unit for remote control, the light receiving sensitivity might be
	deteriorated since the lead bents and attaching angle of the light receiving part may be varied.
	Please do not apply external force onto the infrared deteching unit for remote control. If any external force is applied by
	mistake, please confirm whether lead bending may exist or not.
	If the lead is bent, please correct the angle between the lead and the light receiving part to be 90 degrees or replace
	the infrared deteching unit for remote control (GP1UXC14RK).

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 B temperatures (hard to melt/easy to harden).

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

•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, this is not processed as an error, and operation continues accordingly.

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

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).

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)
