SAFETY INFORMATION
CAUTION
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
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
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.
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.
CAUTION—CLASS 1M INVISIBLE LASER
RADIATION WHEN OPEN, DO NOT VIEW
DIRECTLY WITH OPTICAL INSTRUMENTS.

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
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacturer.
Discord used batteries according to the manufacturer's instructions.

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
1.2 NOTES ON SOLDERING
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.

5.2 ERROR CODE LIST
8-digit display 6-digit display 4-digit display
ERROR-xx ERR-xx E-xx
(2) LIST OF CD ERROR CODES (Error Mode: 0xFD)
Code Classification
Error code to be displayed 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
50 Mechanism Load NG
Eject NG
Disc loading/ejection not completed
--> A foreign object inserted in the mechanism; Disc jammed.
51 Mechanism Failure in retried
turning for ejection
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.”
