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

A

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.

- 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.

B

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:

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

C

CLASS 1

D

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.

E

A specially instructed person should do servicing operation of the apparatus.

LASER PRODUCT

WARNING!

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.

F

2

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.

In addition, be sure that there are no pinched wires, etc.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There 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.

9 There 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.

a Safe 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.

3. Lubricants, Glues, and Replacement parts

Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.

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.

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

- Service Precaution

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.

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.

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.

6. SERVICE MODE

6.1 CD TEST MODE

A

1) Cautions on adjustments
In this product the single voltage (3.3 V) is used for the
regulator. The reference voltage is the REFO1 (1.65 V)
instead of the GND.
If you should mistakenly short the REFO1 with the GND
during adjustment, accurate voltage will not be obtained,
and the servo’s misoperation will apply excessive shock
to the pickup. To avoid such problems:
a. Do not mix up the REFO1 with the GND when
connecting the (-) probe of measuring instruments.

B

C

Especially on an oscilloscope, avoid connecting the (-)
probe for CH1 to the GND.
b. In many cases, measuring instruments have the same
potential as that for the (-) probe. Be sure to set the
measuring instruments to the floating state.
c. If you have mistakenly connected the REFO1 to the GND,
turn off the regulator or the power immediately.

Before mounting and removing filters or leads for
adjustment, be sure to turn off the regulator.

For stable circuit operation, keep the mechanism
operating for about one minute or more after the
regulator is turned on.

2) Test mode
This mode is used to adjust the CD mechanism module.
To enter the test mode.
While pressing the BAND and RDM keys at the same
time, reset.
To exit from the test mode.
Turn off the ACC and back up.

Notes:
a. During ejection, do not press any other keys than the
EJECT key until the loaded disc is ejected.
b. If you have pressed the (->) key or (<-) key during focus
search, turn off the power immediately to protect the
actuator from damage caused by the lens stuck.
c. For the TR jump modes except 100TR, the track jump
operation will continue even if the key is released.
d. For the CRG move and 100TR jump modes, the tracking
loop will be closed at the same time when the key is
released.
e. When the power is turned off and on, the jump mode
is reset to the single TR (91), the RF amp gain is set to 0 dB,
and the auto-adjustment values are reset to the default
settings.

In the test mode, any software protections will not
work. Avoid applying any mechanical or electrical
shock to the mechanism during adjustment.

The RFI and RFO signals with a wide frequency range
are easy to oscillate. When observing the signals,
insert a resistor of 1k ohms in series.

D

The load and eject operation is not guarantied with the
mechanism upside down. If the mechanism is blocked
due to mistaken eject operation, reset the product or
turn off and on the ACC to restore it.
