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 OTHERTHAN 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.

2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
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.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
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.

1. SERVICE PRECAUTIONS
1.1 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.
6. area and a heat sink becomes hot areas. Be careful not to burn yourself.
7. Software update
The software of this product is stored in IC671.
Please replace IC671 when making the version upgrade of software.
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
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.

(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 CRG cannot move toward the inner track.
The CRG cannot move from the inner track.
--> Defective HOME SW; Failure in CRG movement.
7Servo TOC reading NG TOC information cannot be read.
--> The partial disk or TOC content is illegal.
11 Servo Focus Search NG Focusing not available
--> Disc placed upside-down; Stains on the disc; excessive vibration.
17 Servo Setup NG AGC protection does not work. Focus can be easily lost.
--> Scratches or stains on the disc; excessive vibration.
15 Servo Failure in RF data RF not read
--> A CD-R disc that does not contain data loaded
--> A CD-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 disc that does not contain data loaded, or in a rare case, disc placed upside-down.
--> CD signal error.
30 Servo Search Time Out Failed to reach a target address
--> CRG tracking error; Scratches on the disc; Stains on the disc
50 Mechanism Failure in ejection
Load NG
Disc ejection not completed
Disc loading 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.
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.”
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 main 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.
0x: Servo-related errors
1x: Servo-related errors
3x: Servo-related errors
5x: Mechanism-related errors
• How to restore from each error is shown below.
0x, 1x and 3x: ACC-OFF then ON, CD-OFF then ON,
Disc ejection
5X: ACC-OFF then ON, Disc ejection, Disc reloading
