Notes: When the DIGITAL P.C.B. or IC23 on DIGITAL P.C.B. is replaced, this unit will display “Internal Error” and
will not operate properly. The model name, destination and serial number MUST be written to the backup IC
(EEPROM: IC23 on DIGITAL P.C.B.) to have proper operation.
(For detailed procedure, refer to related Service News or Service Bulletin. Or contact your local Yamaha
representative.)
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. Modifi cations 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.

■ TO SERVICE PERSONNEL
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 ohms shunted
by 0.15 μF.
“CAUTION”
“F5401: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 1.25A,
250V FUSE.”
“F5402: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A,
125V FUSE.”
“F5405: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 2A, 63V
CHIP FUSE.”
For C model
CAUTION
F5401: REPLACE WITH SAME TYPE 1.25A, 250V FUSE.
F5402: REPLACE WITH SAME TYPE 6A, 125V FUSE.

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,
RX-V385/HTR-3072
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.

● 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.
