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.

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 REA­SON 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 "POWER" 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 set, 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.

■ 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.

Q

Q

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

TEL [phone] QQ 376315150 892498299

Use an anti-static wrist strap to discharge the static electricity from your body.

TEL [phone] QQ 376315150 892498299

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

TEL

this service manual.

2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage the laser
diode.

3. Handling Precautions for the Traverse Unit (Optical Pickup)

DVD-S2300MK2

1. Handle the traverse unit (optical pickup) gently, as it is an extremely high-precision assembly.

2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.

3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.

■ LOCALE MANAGEMENT INFORMATION

Locale Management Information : This DVD player is designed and manufactured to respond to the Locale Management
Information that is recorded on the DVD disc. If the Locale number described on the DVD disc does not correspond to the

■ OPTICAL PICKUP SELF-DIAGNOSIS AND REPLACEMENT PROCEDURE

An optical pickup self-diagnosis function and tilt adjustment check function have been included in this unit. When repairing,

Q

use the following procedure for effective Self-diagnosis and tilt adjustment. Be sure to use the self-diagnosis function before
replacing the optical pickup when "NO DISC" is displayed. As a guideline, you should replace the optical pickup when the
value of the CD laser drive current is more than 55 (70 for DVD).

Note:

• Check the value within three minutes after applying the power to the player. (When the unit warms up, the result will be
incorrect.)

• Be sure to perform the following operation in the DVD mode.

5. Service Precautions

5.1. Recovery After the DVD Player is Repaired

When the DVD module P.C.B., or a FROM or an EEPROM
on the DVD module P.C.B. has been replaced, carry out
the recovery disc procedure to optimize the drive.
Playback the disc below to perform the recovery
automatically,

Note:

When the recovery procedure is performed, the user
settings will be erased and the factory settings will be
restored as when the initialization procedure is used.
Therefore, it is necessary to write down the content of the
user settings before performing the recovery procedure
and reset it after that.

5.2. Firmware Version-Up of the DVD Module

The firmware of the DVD module 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.
Detailed information on supply of the version-update disc
will be provided in Service News.

Note:

7

3

If the AC power supply is lost during version-updating due

Q

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.
If recovery by using the version-update disc has failed,
start up the TEST mode and initialize the DVD module.
(Refer to the description of the previous section.)
