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 "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.
CAUTION
1110: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 2A, 250V FUSE.
CAUTION
1110: REPLACE WITH SAME TYPE 2A, 250V FUSE.
ATTENTION
1110: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 2A, 250V.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
THE DVD AUDIO/VIDEO RECEIVER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY
QUALIFIED SERVICE PERSONNEL.

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 .
The primary side of the power supply has been indicated with a lightening stroke and a stripe-marked print on the printed
wiring board
Note:
The screws on the DVD mechanism (position 9 in on the exploded view drawing) 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.

■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
Locale number of this DVD player, this DVD player cannot play this disc.
This product incorporates copyright protection
technology that is protected by method claims of
certain U.S. patents and other intellectual
property rights owned by Macrovision

■PREVENTION OF ELECTRO STATIC DISCHARGE
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.

(sheet) or steel sheet
Anti-static wrist strip
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.

■SERVICE HINTS
●Power Supply Unit
The power supply unit has to be replaced in case of
failure. The schematic provided in the manual is only for
information and no service parts will be available.
●DVD Mechanism
1. The DVD mechanism is not a repairable unit and in
case of failure, it has to be replaced with a new DVD
mechanism.
Note: When replacing with a new DVD mechanism, two
solder joints have to be removed after connecting the
OPU flex foil to the mono board.
The solder joints, which shortcircuits the laser diodes to
ground, are for protection against ESD. Refer to Fig. 1
and 2 for location of solder joints.
2. The mono board has to be repaired down to component
level. Repair handling of the monoboard requires a
workshop with sophisticated desoldering tools.
