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.

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 "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.
■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 PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED
SERVICE PERSONNEL.

■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.
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 in the optical pickup. The power supply in the tester will damage the laser
diode.
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. 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.

■OPTICAL PICKUP SELF-DIAGNOSIS AND REPLACEMENT PROCEDURE
1. Self-diagnosis
An optical pickup self-diagnosis function and tilt adjustment check function have been included in this unit. When repairing,
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.

■光ピックアップの故障診断と交換手順
1. 故障診断
本機には、新機能として「光ピックアップ故障診断機能」と「あおり調整確認機能」を内蔵しております。修理時は、次の手法
を用い効率的に故障診断、およびあおり調整を実施ください。
特に「NODISC」表示が出る場合は光ピックアップを交換する前に「故障診断」を行います。レーザー駆動電流の現在値が「55
を越える」場合が光ピックアップ交換の目安になります。
注意
・ 電源を入れてから3分以内に診断をしてください。（プレーヤーが温まると正確な診断ができません。）
・ 下記の操作はDVDモードに設定した状態で行ってください。
