SERVICE MANUAL
100942
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.
■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, F2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A,
125V FUSE.”
CAUTION
F1, F2: REPLACE WITH SAME TYPE 10A, 125V FUSE.
ATTENTION
F1, F2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
About Lead Free Solder
The P.C.B.s installed in this unit are soldered using the following 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)
Side A
Side B
SMT REFLOW Process
MI FLOW Process
Solder Dip
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.

• Starting DIAG
Press the “STANDBY/ON”key while simultaneously
pressing those two keys of the main unit as indicated in the
figure below.
Keys of main unit
Turn on the power while pressing these keys.
• Starting DIAG in the protection cancel
mode
If the protection function works and causes hindrance to
trouble diagnosis, cancel the protection function as
described below, and it will be possible to enter the DIAG
mode. (The protection functions other than the excess
current detect function will be disabled.)
Press the “STANDBY/ON”key while simultaneously
pressing those two keys indicated in the figure above. At
this time, keep pressing those two keys for 3 seconds or
longer.
In this mode, the “SLEEP”segment of the FL display of the
main unit flashes to indicate that the mode is DIAG mode
with the protection functions disabled.
CAUTION!
Using this product with the protection function disabled
may cause damage to itself. Use special care for this point
when using this mode.
• Canceling DIAG
[1] Before canceling DIAG, execute setting for PRESET of
DIAG menu No.11 (Memory initialization inhibited or
Memory initialized).
* In order to keep the user memory stored, be sure to
select PRESET INHIBIT (Memory initialization
inhibited). Any protection history will remain in
memory.
[2] Turn off the power by pressing the “STANDBY/ON”
key of the main unit or the “STANDBY”key of the
remote controller.
Cause: An excessive current flowed through the power
amplifier.
Turning on the power without correcting the abnormality
will cause the protection function to work immediately and
the power supply will instantly be shut off.
Note)
•Applying the power to a unit without correcting the
abnormality can be dangerous and cause additional
circuit damage.
•The output transistors in each amplifier channel
should be checked for damage before applying any
power.
•Amplifier current should be monitored by measuring
across the emitter resistors for each channel.
When there is a history of protection function:
• Display provided when DIAG started
When the monitor is connected, DIAGNOSTIC MENU
appears on its screen as shown in the figure. (It remains
on display until DIAG is cancelled.)
The FL display of the main unit displays the protection
function history data and the version (1 alphabet) and
then the DIAG menu [sub-menu (YSS 0dB) of DIAG menu
No.1 DSP THROUGH] a few seconds later.

Cause: The voltage in the power supply section is
abnormal.
Supplementary information: The abnormal voltage is
displayed in % based on 5V as 100%.
Turning on the power without correcting the abnormality
will cause the protection function to work 1 second later
and the power supply will be shut off.
Cause: DC output of the power amplifier is abnormal.
Supplementary information: The abnormal voltage is
displayed in % based on 5V as 100%.
Turning on the power without correcting the abnormality
will cause the protection function to work 3 seconds later
and the power supply will be shut off.
Cause: The temperature of the heat sink is excessive
high.
Supplementary information: The abnormal voltage is
displayed in % based on 5V as 500%.
Turning on the power without correcting the abnormality
will cause the protection function to work 1 second later
and the power supply will be shut off.
* Additional causes of protection can be due to loose
connections, associated components, CPU, etc.
* For the protection voltage value, refer to DIAG menu
No.12 described later.
• Display during menu operation
During the DIAG operation, the menu list described in the
section of the startup screen appears on the
superimposed screen and the function at work is indicated
on the FL indicator. The contents displayed during the
function operation are described in the later section on
details of functions.
• History of protection function
When the protection function has worked, its history is
stored in memory with a backup. Even if no abnormality
is noted while servicing the unit, an abnormality which
has occurred previously can be defined as long as the
backup data has been stored.
The history of the protection function is cleared when
DIAG is cancelled by selecting PRESET RESERVED
(Memory initialized) of DIAG menu No. 11 or when the
backup data is erased.
• Operation procedure of DIAG menu and
SUB-MENU
There are 18 MENU items, each of which has some SUB-
MENU items.
DIAG menu selection
Select the menu using the PROGRAM knob.
