IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already
known and understood by the users, and have therefore not been restated.
WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal
injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons,
we advise all YAMAHA product owners that any service required should be performed by an authorized
YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or
recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and
service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable
and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please
contact the distributor's Service Division.
WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

TABLE
■TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked Z
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 ohms 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: Laser Safety
This product contains a laser beam component. This
component may emit invisible, as well as visible radia-
tion, which may cause eye damage. To protect your
eyes and skin from laser radiation, the following pre-
cautions 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 perform-
ance of procedures other than those specified herein
may result in hazardous radiation exposure.
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.
Laser Emitting conditions:
1) When the Top Cover is removed, and the STANDBY/
ON SW is turned to the "ON" position, the laser compo-
nent 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 pro-
vided elsewhere in this manual. Adjustment of this con-
trol can increase the laser emission level from the de-
vice.
警告：レーザーの安全対策
本機はレーザー光線を放射する部品を搭載しています。こ
の部品が放射するレーザー光線は目に損傷を起こします。
このレーザー光線から目及び肌を保護するために、本機の
修理作業中は下記の注意を厳守してください。
1）テスト時または修理時、目及び肌を光ピックアップか
ら30cｍ以上離してください。いかなる場合もレーザー
光線を見つめないでください。
2）光ピックアップの再調整及び分解はしないでくださ
い。
3）このマニュアル上で指定されている以外の制御、調
整、手順はレーザー光線を照射される結果を招く恐れ
があります。
レーザー放射条件
1）トップカバーを取り外しSTANDBY/ONスイッチをONに
すると、ディスク検知のため5〜10秒間、光ピック
アップからレーザー光線が放射されます。この間、修
理はしないでください。
ディスクが検知されなければ、レーザー光線の放射は
停止します。ディスクがセットされている場合、ディ
スクで遮られるのでレーザー光線は修理担当者に届き
ません。
2）レーザーパワーレベルは光ピックアップ基板上のVRに
より調整可能ですが、工場出荷前に調整セット済みな
ので、このVRは廻さないでください。このVRを廻す

Warning for power supply
The primary side of the power supply carries live mains voltage when the player is connected to the mains even when
the player is switched off !
This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.
Service personnel have to take precautions to prevent touching this area or components in this area.
Note:
The screws on the DVD mechanism may never be touched, removed or re-adjusted.
Handle the DVD mechanism with care when the unit has to be exchanged!
The DVD mechanism is very sensitive for dropping or giving shocks.

■PREVENTION OF ELECTROSTATIC DISCHARGE
■LOCALE MANAGEMENT INFORMATION
Locale Management Information : This DVD player is designed and manufactured to respond to the Locale
Management Information that is recorded on a DVD disc. If the Locale number described on the DVD disc does not
correspond to the Locale number of this DVD player, this DVD player cannot play this disc.
This product incorporates copyright pro-
tection technology that is protected by
method claims of certain U.S. patents and
other intellectual property rights owned by
Macrovision Corporation and other rights
owners. Use of this copyright protection
technology must be authorized by
Macrovision Corporation, and is intended
for home and other limited viewing uses
only unless otherwise authorized by
Macrovision Corporation. Reverse engineer-
ing or disassembly is prohibited.
The laser diode in the DVD mechanism may be damaged due to static electricity from clothes or the human body. Use caution
to prevent electrostatic damage when servicing or handling the DVD-mechanism.
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.
1MΩ
Conductive material
(sheet) or steel sheet
Anti-static wrist strap
2. Handling Precautions for DVD mechanism
1. Handle the DVD mechanism 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.
