Cautions for servicing
A
This product uses 5V and 3.3V as standard voltages.
The electrical potential that is the reference for signals,
is not GND, but VREF (approximately 2.2V) and VHALF
(approximately 1.65V).
During product adjustments, if the reference voltage is
mistakenly taken as GND, and a grounding contact is
made, not only would it be impossible to measure the
accurate electrical potential, but also the servo motor
would malfunction, resulting in the application of a
strong impact on the pick up. The following precautionary measures should be strictly adhered to, in order to
B
avoid such problems.
The reference voltage and GND should not be confused
when using the minus probe of a measurement device.
When an oscilloscope is being used special care should
be taken to make sure that the reference voltage is not
connected to the probe of ch1 (on the minus side),
while the probe of ch2 (on the minus side), is connected
to GND. Further, since the body frame of most measurement devices have the same electrical potential as
the minus side of the probe, the body frame of the measurement device should be set to floating ground.
C
If the reference voltage is connected to GND by mistake, turn the regulator OFF immediatel y, or turn the
power OFF.
• Remove the filters and wires used for measurements
only after the regulator has been turned OFF.
• After the power supply is turned on, regulator ON the
following adjustment and measurement are promptly
done.
• Whenever the product is in the test mode, the software
will not take any protective action. For this reason,
special care should be taken to make sure that no
mechanical or electrical shock could be applied to the
product when taking measurements in the test mode.
• Whenever the EJECT key is pressed to eject the disk,
no other keys, other than the EJECT key, should be
pressed until the disk eject action has been completed.
• Press the EJECT key only after the disk has stopped
completely.
• If the product hangs up turn the power OFF immediately.
• Laser didoes may be damaged, if the volume switch for
the laser power adjustment of the pick up unit, is turned.
• Test mode starting procedure
The test mode can be selected from the navigation
test mode.
Please use the " remote control unit of the product
accessory" after the test mode starts.

1. Pick up unit replacement
2. Spindle motor replacement
3. Carriage chassis replacement
4. Pick up unit main shaft replacement
5. Pick up unit sub-shaft replacement

Symptoms that can occur if proper adjustments are not made: Error rate reaches 10 (10 or less under normal condi-
-3
tions).
The RF jitter becomes more pronounced - the RF waveform becomes deformed.
Retraction of the tracking and the servo motor, become unstable.
A
Cautions for performing adjustments: Do not look directly into the laser beam for any prolonged periods of time.
Procedure:
1. Replace the cable, connecting the product's main unit and the DVD mechanical module, with a 40-pin extended flexible cable (GGD1170), and turn the DVD mechanical module upside down, in order to proceed with pick-up unit adjustments.
2. Remove adhesive materials from the pick-up unit, using tweezers.
(Note) Make sure that adhesive material fragments are not scattered while removing the adhesive from the unit. Be
also very careful not to exert excessive force on the actuator.
3. Connect the unit to an oscilloscope, referring to the connection diagram.
4. Turn the product power ON, and load the disk for adjustments (GGV1018).
5. Set the disk type to single-layer DVD in the front-end test mode, turn the power ON and then move the pick-up to
B
the middle radius.
6. LD ON.
7. Close in the focus(Do not carry out 'T.Bal adjustment' and 'Tracking close'.)
8. Maximize the level by slightly turning the skew adjustment screw A, while looking at the RF waveform level on the
oscilloscope.
Next, maximize the level by turning the skew adjustment screw B, slightly. Repeat this procedure three times and
adjust the unit to attain a maximum level.
9. Turn the power OFF in the test mode, and eject the disk after verifying that it has stopped spinning.
10. Apply adhesive and screw lock materials, to the locations specified in the pick-up diagram (shown below).
Apply the adhesive material to secure the resin components on the pick-up chassis.
Apply the screw lock material to secure the screws on the pick-up chassis.
Do not apply any of these materials to the pick-up section or mechanical sections, which are not specified.
C
Keep the unit away from vibration or shock until the materials securely fix the components and screws in place.

GENERAL INFORMATION
DIAGNOSIS
DISASSEMBLY
- Handling the mechanical module
1. The mechanical module should be handled by holding
the upper frame and main frame of the mechanical module.
2. The front section of the upper frame is not very sturdy,
so this section should not be held too firmly (see fig.1).
A
B
- Removing the DVD Core Unit R
1. Bring the mechanism to a locked position (disk load
standby position).
2. Turn the mechanical module upside down.
3. Set the pick-up flexible cable to a shorted position on
the land end (the other is auxiliary), and turn the SW
knob in the direction opposite to OP (see fig.2).
4. Remove the pick-up flexible cable and the CRG flexible
cable from the connector. Remove the solder on the
lead wires of the load motor.
5. Remove screws at two locations, and remove the DVD
Core Unit R (lift the board in the direction of the white
arrow shown in fig.3, and remove it out diagonally).
Do not hold onto this area.

- Removing the PU unit (see fig.4)
1. Lift the pick-up rack to the center of the axis of the rack,
turn it 90 degrees first, then press on it lightly, and fix it
in place temporarily.
2. Remove the screw that keeps the main shaft clamp
spring in place, and remove the main shaft clamp
spring.
3. Remove the PU unit with the main shaft attached.
