SAFETY INFORMATION

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:

This 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.

CAUTION:

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

- 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.

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)

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.

CAUTION

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

1. SERVICE PRECAUTIONS

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.

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).

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.

Details and possible causes

10 Servo Carriage Home NG The pickup cannot move toward the inner track.

The CRG cannot move from the inner track.

--> Defective HOME SW; Failure in CRG movement.

07 Servo TOC reading NG TOC information cannot be read.

--> The partial disk or TOC content is illegal.

11 Servo Focus NG Focusing not available

--> Disc placed upside-down; Stains on the disc; excessive vibration.

17 Servo Setup NG The laser output cannot be adjusted. Focus can be easily lost.

--> Scratches or stains on the disc; excessive vibration.

15 Servo RF NG The digital signal from the disc cannot be detected.

--> A CD-R/RW disc that does not contain data loaded.

12 Servo Spindle Lock NG

Subcode NG RF-amp NG

Spindle not locked. Subcode not readable. Proper RF AMP gain not obtained.

--> Defective spindle; Scratches or stains on the disc; excessive vibration.

-->

A CD-R/RW disc that does not contain data loaded, or in a rare case, disc placed upside-down.

--> RF signal error.

30 Servo Search Time Out Failed to reach a target address. And, the search became a timeout.

--> Carriage/Tracking error; Scratches on the disc; Stains on the disc

Disc could not be ejected even after disc turning had been retried.

--> A foreign object inserted in the mechanism; Disc jammed.

ERROR CODES

(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.

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.

• The 2 high-order digits of an error code denote the main classification, shown below. code classification 0x 1x Servo-related errors 3x 5x Mechanism-related errors

• How to restore from each error is shown below. Servo-related errors(0X, 1X, 3X) : Servo-related errors CD Off, Eject, ACC Off, Back-up Off, Communication reset, Reset Load NG/Eject NG(50) : Reload, Eject, ACC Off, Back-up Off, Communication reset, Reset Failure in retried turning for ejection : CD On, Eject, ACC Off, Back-up Off, Communication reset, Reset

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, 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.”

If the power supply is turned OFF during rewriting, retry the rewriting.

Displayed when there is no upgrading file in USB memory or the data of upgrading file is different. 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.

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. The upgrading using USB is disabled, so it is necessary to write programs in serial Flash using E10A.

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.

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. 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)
