■WARNINGS
WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic
(where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency
(and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.
WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may
cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during
servicing of the unit.
1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.
2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.
3) CAUTION: Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
Laser Emitting conditions:
1) When the Top Cover is removed and the "STANDBY/ON" SW is turned to the "ON" position, the laser component will emit
a beam for several seconds to detect if a disc is present. During this time (5 - 10 sec.) the laser may radiate through the
lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser
emissions.
2) The laser power level can be adjusted with the VR on the pick-up PWB. However, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual.
Adjustment of this control can increase the laser emission level from the device.
■TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked s
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●Meter impedance should be equivalent to 1500 ohm shunted
by 0.15µF.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
THE DVD-VIDEO PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED SERVICE

■PREVENTION OF ELECTRO STATIC DISCHARGE
The laser diode in the traverse unit (optical pickup) may be damaged due to static electricity from clothes or the human body.
Use caution to prevent electrostatic damage when servicing or handling the laser diode.
1. Grounding for electrostatic damage prevention
Some devices, such as the DVD player, use an optical pickup (laser diode) that will be damaged by static electricity in the
working environment. Only attempt service after ensuring that all grounding procedures have been completed.
1. Worktable grounding
Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.
2. Human body grounding
Use an anti-static wrist strap to discharge the static electricity from your body.
1M Conductive material
(sheet) or iron sheet
Anti-static wrist strip
2. Handling of the optical pickup
1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both ends of the
laser diode are short-circuited. After installing the new part, remove the short circuit according to the correct procedure in
this service manual.
2. Do not use a tester to check the laser diode for the optical pickup. Failure to do so will damage the laser diode due to the
power supply in the tester.
3. Handling Precautions for the Traverse Unit (Optical Pickup)
1. Handle the traverse unit (optical pickup) gently, as it is an extremely high-precision assembly.
2. When replacing the optical pickup, install the flexible cable and cut its short land with wire cutters. See the optical pickup
replacement procedure in this service manual. Before replacing the traverse unit, remove the shorting pin for preventing
static electricity damage and install the new unit. Reconnect the connector as quickly as possible.
3. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.
4. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.

Cautions to Be Used Before Replacing the Optical Pickup Unit and Spindle Motor Assembly
Before replacing the optical pickup unit and spindle motor assembly, check the total usage hours for each of them. The
checking method is as follows:
Note: Each of these procedures should start with the unit stopped.
Cautions to be taken when replacing the optical
pickup
The optical pickup may become damaged due to static
electricity from the human body. Take proper protection
measures against static electricity before repairing the
parts around the optical pickup. (See the page describing
the PREVENTION OF ELECTRO STATIC DISCHARGE.)
1. Do not touch the areas around the laser diode and
actuator.
2. Do not judge the laser diode with a tester. (The tester
will damag the diode.)
3. It is recommended to use a anti-static soldering iron
for soldering or desoldering on the pickup.
(Recommended soldering iron) HAKKO ESD
Product
4. Solder the land of the flexible cable in the optical
pickup.
Note:
•When using a soldering iron which is not anti-static,
short-circuit the terminal face of the flexible cable
with a clip. After that, short-circuit the land.
•After the repairing work is completed, remove the
solder according to the correct procedure shown in
this service manual.

the remote control unit for a few second.
6.2. Cancellation
The lock can be cancelled by the same procedure as used in setting. "UNLOCKED" is displayed on cancellation.
(Disconnecting the power cable from the power outlet does not cancel the lock function.)
7. Service Precautions
7.1. Recovery after the dvd player is repaired
When a FROM or an EEPROM in and on the module P.C.B. has been replaced, carry out the recovery disc procedure to
optimize the drive.
Playback the disc above to perform the recovery automatically,
Recovery disc: RFKZD5TR001 (AAX27810)
Note:
This unit requires no initialization procedure carried out as when traditional DVD players were repaired.
When the recovery measures are taken, the customer setting will return to the factory setting and the player will be reset.
7.2. Firmware version-up of the DVD player
The firmware of the DVD player may be updated to improve the quality, including optimizing operationability and
playability with substandard discs.
The version-update disc also has a recovery function so that you don't need to use the recovery disc again.
Note:
If the AC power supply is lost during version-updating due to a power failure, the version-update is improperly carried out.
In such a case, replace the FROM and carry out the version-update again.
The product number of the version-update disc will be noticed when it is supplied.
8. Handling After Completing Repairs
Use the following procedure after completing repairs.
8.1. Method
Confirm that the power is turned on:
1. Press the "OPEN/CLOSE" button to close the tray.
2. Press the "POWER" button to turn off the power.
3. Disconnect the power plug from the outlet.
8.2. Precautions
Do not disconnect the power plug from the outlet with the tray still open, then close the tray manually.
