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.

■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 ohms shunted
by 0.15µF.
“CAUTION”
“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 1.6A,
125V FUSE.”
CAUTION
F1: REPLACE WITH SAME TYPE 1.6A, 125V FUSE.
ATTENTION
F1: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 1.6A, 125V.
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.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
About Lead Free Solder
Side A
Side B
SMT REFLOW Process
MI FLOW Process
Solder Dip
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.
2. If lead solder must be used, be sure to remove lead free solder from each terminal section of the parts to be replaced and from the area
around it completely before soldering, or make sure that the lead free solder and lead solder melt together fully.
The P.C.B.s installed in this unit are soldered using the following solder.

■DISASSEMBLY PROCEDURES
(Remove parts in the order as numbered.)
Disconnect the power cable from the AC outlet.
1. Removal of Front Grille Ass’y
* The Front Grille Ass’y is fixed to the cabinet with dowels at 7
locations.
As a flatblade screwdriver is used for removal, use special
care not to cause damage to the Cabinet Ass’y.
a. Using the flatblade screwdriver inserted in the gap between
the Front Grille Ass’y and the Cabinet Ass’y (bottom side first),
push up the Front Grille Ass’y. (Fig.1)
b. Remove the Front Grille Ass’y by lifting a metalblade up.
(Fig.1)
* When installing the Front Grille Ass’y, apply quick-drying bond
or the like to dowels and then fit them into dowel holes for
secure installation. (The Front Grille Ass’y will come off easily
if its dowels are fitted into dowel holes without applying quick-
drying bond or the like.)
