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 specifi cally YAMAHA Products, are already known
and understood by the users, and have therefore not been restated.
WARNING:
IMPORTANT:
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
specifi cations are subject to change without notice or obligation to retrofi t. Should any discrepancy appear to exist, please contact the
distributor's Service Division.
WARNING:
IMPORTANT:
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 specifi ed. 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.
The presentation or sale of this manual to any individual or fi rm does not constitute authorization, certifi cation or
recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
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).
Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

About lead free solder /
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.

■ SERVICE PRECAUTIONS /
サービス時の注意事項
Safety measures
• Some internal parts in this product contain high voltages
and are dangerous.
Be sure to take safety measures during servicing, such
as wearing insulating gloves.
• Note that the capacitors indicated below are dangerous
even after the power is turned off because an electric
charge remains and a high voltage continues to exist
there.
Before starting any repair work, connect a discharging
resistor (5 k-ohms/10 W) to the terminals of each
capacitor indicated below to discharge electricity.
The time required for discharging is about 30 seconds
per each.

firmware version and checksum”)
● Starting Self-Diagnostic Function in
the protection cancel mode
If the protection function works and causes hindrance
to troubleshooting, cancel the protection function by the
procedure below, and it will be possible to enter the selfdiagnostic function mode. (The protection functions other
than the excess current detect function will be disabled.)
While pressing the “TONE CONTROL” and “INFO” keys,
press the “
pressing those 2 keys and “
or longer.
The self-diagnostic function mode is activated with the
protection functions disabled.
In this mode, the “SLEEP” segment of the FL display flashes
to indicate that the mode is self-diagnostic function mode
with the protection functions disabled.
CAUTION!
Using this unit with the protection function disabled may
cause further damage to this unit. Use special care for
this point when using this mode.
2. When the protection function worked to turn
off the power:
The information of protection function which worked at
that time is displayed. Then “A1-1. DSP MARGIN” is
displayed in a few seconds.
Note: At that time if you restart the self-diagnostic
function after turning off the power once, “NO
PROTECT” will be displayed. That is because
that situation is equal to “1. When the power is
turned off by usual operation:”.
However history of the protection function is
stored in memory as backup data. For details,
refer to “P2. PROTECTION HISTORY” menu.
2-1. When there is a history of protection function
due to excess current.
IPROTECT
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.
• Applying the power to this unit without correcting
the abnormality can be dangerous and cause
additional circuit damage. To avoid this, if “I
PROTECT” protection function works 1 time, the
power will not turn on even when the “
key is pressed. In order to turn on the power
again, start up the self-diagnostic function.
• The output transistors in each amplifier channel
should be checked for damage before applying
power to this unit.
• Amplifier current should be monitored by
measuring DC voltage across the emitter resistors
for each channel.

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.
Turning on the power without correcting the abnormality
will cause the protection function to work in 5 seconds
and the power supply will be shut off.

Supplementary information: The protection function
worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality
will cause the protection function to work in 1 seconds
and the power supply will be shut off.
Notes:
• Applying the power to this unit without correcting
the abnormality can be dangerous and cause
additional circuit damage. To avoid this, if “PS”

● History of protection function
When the protection function has worked, its history
is stored in memory as backup data.
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.
