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 specifi cally Yamaha Products, are already known
and understood by the users, and have therefore not been restated.

WARNING:

IMPORTANT:

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. Modifi cations are, therefore, inevitable and specifi cations
are subject to change without notice or obligation to retrofi t. Should any discrepancy appear to exist, please contact the distributor's
Service Division.

WARNING:

IMPORTANT:

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 specifi ed. 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.

The presentation or sale of this manual to any individual or fi rm does not constitute authorization, certifi cation or

recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.

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).

Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

by 0.15 μF.

WALL

OUTLET

• Leakage current must not exceed 0.5mA.

• Be sure to test for leakage with the AC plug in both polarities.

WARNING: CHEMICAL CONTENT NOTICE!

This product contains chemicals known to the State of California to cause cancer, 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.

About lead free solder

All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.

Among some types of lead free solder currently available, it is recommended to use one of the following types for the
repair work.

• Sn + Ag + Cu (tin + silver + copper)

• Sn + Cu (tin + copper)

• Sn + Zn + Bi (tin + zinc + bismuth)

Caution:

As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead
solder, be sure to use a soldering iron suitable to each solder.

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/1 feet
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.

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 accidentally 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 BD/DVD mechanism may never be touched, removed or re-adjusted.
Handle the BD/DVD mechanism with care when the unit has to be exchanged!
The BD/DVD mechanism is very sensitive for dropping or giving shocks.

BD-S677

■ PREVENTION OF ELECTROSTATIC DISCHARGE

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect
transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence
of component damage caused by electrostatic discharge (ESD).

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD
on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging
ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as
aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD
protected)” can generate electrical charge sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it.
(Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil
or comparable conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into which the device will be installed.

CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as
brushing together of your fabric clothes or lifting of your foot from a carpeted floor can generate static electricity (ESD)
sufficient to damage an ES device).

Grounding for electrostatic breakdown prevention

1. Human body grounding.
Use the antistatic wrist strap to discharge the static electricity from your body.

2. Work table grounding.
Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.

Caution:

The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch
the optical pickup.
