SERVICE MANUAL
101048
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 sand
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.
●Leakage current must not exceed 0.5mA.
●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 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.
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.

Opening message
When there is no protection history
When there is a history of protection function:
When there is a history of protection function due to excess current
PRI PRT:xxx
Cause: An excessive current flowed through the power amplifier.
Supplementary information:
As current of the power amplifier is detected, the abnormal channel can be identified by checking the current
detect transistor.
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.
When there is no history of protection function:
AD value when the protection function is working
AD value when the protection function is working
When there is a history of protection function due to abnormal DC output
Cause: DC output of the power amplifier is abnormal.
Supplementary information:
The protection function worked due to a DC voltage appearing at the speaker terminal.
A cause could be a defect in the amplifier.
If the power is turned on with the abnormality unsolved, the protection function works in about 3 seconds to
turn off the power.
PRD PRT:xxx
• Starting DIAG
Press the “STANDBY/ON” key while simultaneously pressing those two keys of the main unit as indicated in the figure
below.
Turn on the power while pressing these keys.
Keys of main unit
• Canceling DIAG
1. Before canceling DIAG, execute setting for FACTORY PRESET of DIAG menu No.8 (Memory initialization inhibited
or Memory initialized).
* In order to keep the user memory stored, be sure to select PRESET INHIBITED (Memory initialization inhibited).
2. Turn off the power by pressing the “STANDBY/ON” key of the main unit.
• Display provided when DIAG started
On the FL display of the main unit, an opening message (including the protection history) appears for a few seconds
followed by the DIAG menu display (1. ANALOG BYPASS).
When there is a history of protection function due to abnormal voltage in the power supply section
PRV PRT:xxx
Cause: The voltage in the power supply section is abnormal.
Supplementary information:
The protection function worked due to a defect or overload in the power supply.
If the power is turned on with the abnormality unsolved, the protection function works in about 1 second to
turn off the power.
AD value when the protection function is working
Note)
• Applying the power to the main unit without correcting the abnormality can be dangerous and cause addi-
tional circuit damage. To avoid this, if “PRI” and “PRD” protection function has been activated 3 times
continuously, the power will not turn on even when the “STANDBY/ON’ key is pressed. In order to turn on
the power again, disconnect the power cable of the main unit from the AC outlet once and then reconnect it
again.
• The output transistors in each amplifier channel should be checked for damage before applying power of
the main unit.
• Amplifier current should be monitored by measuring across the emitter resistors for each channel.
• 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 the main unit. Use special care
for this point when using this mode.

When there is a history of protection function due to excessive heat sink temperature
Cause: The temperature of the heat sink is excessive.
Supplementary information:
The protection function worked due to the temperature limit being exceeded.
Causes could be poor ventilation or a defect related to the thermal sensor.
If the power is turned on with the abnormality unsolved, the protection function works in about 1 second to turn off the
power.
For detection of each protection function, refer to DIAG menu described later.

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. 8 or when the backup data is erased.
