SAFETY INFORMATION
CAUTION:
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
CLASS 1
LASER PRODUCT
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 W(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.
-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.
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.

8There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
aSafe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
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
1.2 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.
6. EJECT LOCK MODE for CD mechanism
In order to enter "EJECT LOCK" mode, reset start while
pressing the "DISP" and "BAND/ESC" keys together.
Pressing the "DISP" and "BAND/ESC" keys until monitor
backlight is turned on.
In order to exit "EJECT LOCK" mode, follow the same
steps to enter this mode.
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
-Error Messages
If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of
the error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from
the users and also for facilitating trouble analysis and repair work in servicing.
(1) Basic Indication Method
1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN
(minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO
remains in blank as before.
2) Head unit display examples
Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.
8-digit display 6-digit display 4-digit display
ERROR-xx ERR-xx E-xx
(2) Error Code List
Code Class Displayed error code Description of the code and potential cause(s)
10 Electricity Carriage Home NG CRG can't be moved to inner diameter.
SERVO LSI Com- CRG can't be moved from inner diameter.
munication Error -> Failure on home switch or CRG move mechanism.
Communication error between microcomputer and SERVO LSI.
11 Electricity Focus Servo NG Focusing not available.
-> Stains on rear side of disc or excessive vibrations on REWRITABLE.
12 Electricity Spindle Lock NG Spindle not locked. Sub-code is strange (not readable).
Subcode NG -> Failure on spindle, stains or damages on disc, or excessive vibrations.
A disc not containing CD-R data is found.
Turned over disc are found, though rarely.
CD signal error.
17 Electricity Setup NG AGC protection doesn't work. Focus can be easily lost.
-> Damages or stains on disc, or excessive vibrations on REWRITABLE.
30 Electricity SearchTime Out Failed to reach target address.
-> CRG tracking error or damages on disc.
44 Electricity ALL Skip Skip setting for all track.
(CD-R/RW)
50
Mechanism CD On Mech Error Mechanical error during CD ON.
-> Defective loading motor, mechanical lock and mechanical sensor.
A0 System Power Supply NG Power (VD) is ground faulted.
-> Failure on SW transistor or power supply (failure on connector).
Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).
UnreadableTOC does not constitute an error. An intended operation continues in this case.
Upper digits of an error code are subdivided as shown below:
1x: Setup relevant errors, 3x: Search relevant errors, Ax: Other errors.
