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.

1. Critical Components Information.
Components having special characteristics are marked 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.

■ADJUSTMENT
Tilt Adjustment of Disc Motor
After replacing parts in the Traverse Unit, it is necessary
to adjust the Tilt Adjustment of Disc Motor from bottom
side.
Please follow the following procedures for adjusting.
When the following parts have been replaced, disc
motor adjustment will be required.
1. The disc motor.
2. The laser pick-up.
3. The traverse motor unit.
4. The parts around the laser pick-up (rail, etc.).
●Extension cable
1. 35-pin flat cable for servicing AAX08660
2. Stabilizer for servicing AAX07720
Name Part No.

Unit : mm
Caution:
1. Optical adjustment inside the laser pick-up is not
possible.
2. Prior to adjusting, take countermeasures to prevent
damage from static electricity.
Preparation before adjustment (Installation of the
traverse unit)
Be sure to make both your body and the work
table grounded.
a. Connect the power plug and then turn on the power
switch.
b. When the clamp has moved up, turn off the power
switch and disconnect the power plug.
c. Remove the Tray referring to "Removal of Tray" on
page 7.
d. Remove the Clamp Assembly.
e. Remove the Traverse Unit.
(Take the protection measure against static electricity
for the Laser Diode except when replacing the Laser
Pick-up.)
f. Place the Adjusting Box on the CM-200 unit (to
support the traverse unit). (Fig. 15)
g. After replacing the parts, place the Traverse Unit on
the Adjusting Box. (Fig. 15)
Caution (removal of the measure to protect the laser diode
against an electrostatic breakdown)
Unsolder the Land located at the center of the flexible
cable of the laser pickup for the open circuit.
h. Connect the Traverse Unit and the Main P.C.B. with
an extension cable. (Fig. 15)
Caution
When connecting the extension cable, be careful not to
touch the terminal of the cable. (The laser pickup is
easy to be damaged.)
i. Connect the power plug and turn on the power
switch.

Adjustment Procedures
After Adjusting Check the following
1. After adjusting by the DVD test disc, play a video CD or CD-DA and check that there is no abnormal operation.
1. Play back the DVD test disc and then place the unit
in play mode with title 8, then push the Pause
button.
2. At first, Adjust Tangential Adjustment Screw then
adjust Tilt Adjustment Screw with the Hex Wrench
(2.0 mm) from bottom side.
Repeat 2 to 3 times alternately until the waveform
at JIT OUT indicated below is obtained.
Final adjustment should be Tilt Adjustment.
●The valley sections of the waveform should be as
flat as possible.
●The total DC level should be obtained minimized as
much as possible.
●The waveform whisker sections will not disappear.
Measurement Point Adjustment Point Mode Test Disc Measuring Equipment Adjustment Value
JIT OUT TangentialADJ. screw Play DVDT-S01 Oscilloscope Adjust untill the bottom section
(See page 14) Tilt ADJ. screw (title 8) DC 500 mV/div of the waveform becomes flat and
Pause 20 msec/div the DC components are minimum.
