SERVICE MANUAL
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.

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 ohm shunted
by 0.15µF.

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.
About 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:
1. 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.
The P.C.B.s installed in this unit are soldered using the fol-
lowing 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
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.

2. If lead solder must be used, be sure to remove lead-free
solder from each terminal section of the parts to be re-
placed and from the area around it completely before sol-
dering, or make sure that the lead-free solder and lead
solder melt together fully.

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.
WARNING
The use of optical instruments with this product will increase eye hazard.
Repair handling should take place as much as possible with a disc loaded inside the player.

1. Removal of Front Grille
The Front Grille is fixed to the cabinet with dowels
at 6 locations. As a screwdriver (for slotted head
screw) is used for removal, use special care not to
cause damage to the cabinet.
a. Using the screwdriver inserted in the gap between
the Front Grille and the cabinet (bottom side first),
push up the Front Grille.
b. Remove the Front Grille by lifting it up.
* When installing the Front Grille, apply quick-drying
bond to the dowels and then fit them into dowel holes
for secure installation. (The Front Grille will come off
easily if its dowels are fitted into dowel holes only.)
2. Removal of Rear Panel
Remove 14 screws ( q ) in Fig. 2.
* Arrow marks ( ) are printed to identify the screws to
be removed.
* When assembling the Rear Panel, check to ensure that
the packing is not damaged so as to prevent air leakage
from occurring.
