When the DIGITAL P.C.B. or IC82 on DIGITAL (1) P.C.B. is replaced, this unit will display “Internal Error” and will
not operate properly. The model name MUST be written to the backup IC (EEPROM: IC82 on DIGITAL (1) P.C.B.) to
have proper operation. (For detailed procedure, refer to related Service News or Service Bulletin. Or contact your
local Yamaha representative.)
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 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.

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 F.
For U model
“CAUTION”
“F3701: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 2A,
250V FUSE.”
“F3702: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 8A,

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
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.
For details, refer to “PRINTED CIRCUIT BOARDS”.

the beginning again.
● Initializing the back-up IC (EEPROM: IC82 on DIGITAL P.C.B.)
After updating the firmware, the back-up IC MUST be initialized by the following procedure to store the setting
information (soundfield parameters, system memory and tuner presetting, etc.) properly.
Start up the self-diagnostic function and select “S3. FACTORY PRESET” menu.
(For details, refer to “SELF-DIAGNOSTIC FUNCTION”)
Select “PRESET RSRV”, press the “MAIN ZONE
the back-up IC is initialized.
” key to turn off the power once and turn on the power again. Then
● Required Tools
• USB storage device
• Firmware
R0331-xxxx.bin
● Preparation
1. Download the latest firmware from the specified download source to the folder of the PC.
2. Copy the latest firmware from the PC to the root folder of the USB storage device.
Note: When the latest firmware is copied to a sub-folder of the USB storage device, the update will not proceed.
