SERVICE MANUAL

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.

This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive

harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON

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.

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.

■TO SERVICE PERSONNEL

• Leakage current must not exceed 0.5mA.

• Be sure to test for leakage with the AC plug in both polarities.

本機に搭載されているすべての基板およびハンダ付けに

よる接合部は無鉛ハンダでハンダ付けされています。

無鉛ハンダにはいくつかの種類がありますが、修理時に

は下記のような無鉛ハンダの使用を推奨します。

󱾁 Sn+Ag+Cu（錫+銀+銅）

󱾁 Sn+Cu（錫 + 銅）

󱾁 Sn+Zn+Bi（錫 + 亜鉛 + ビスマス）

注意：

40℃程度高くなっていますので、それぞれのハンダに合っ

たハンダごてをご使用ください。

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

安全対策

・ この製品の内部には高電圧部分があり危険です。修理

の際は、絶縁性の手袋を使用するなどの安全対策を

行ってください。

・ 下記のコンデンサには電源を OFF にした後も電荷が残

り、高電圧が維持されており危険です。

修理作業前に放電用抵抗（5k Ω /10W）を下記の各コ

ンデンサの端子間に接続して放電してください。

放電所用時間は各々約 30 秒間です。

MAIN（1）P.C.B. の C1076、C1082 〜 1086

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.

C1076, C1082–1086 on MAIN (1) P.C.B.

C3706 on VIDEO (2) P.C.B.

When the following parts are replaced, the firmware must

be updated to the latest version.

DIGITAL P.C.B.

FPGA Flash ROM: IC82 on DIGITAL P.C.B.

NETWORK Flash ROM: IC904 on DIGITAL P.C.B.

DSP(TI) Flash ROM: IC923 on DIGITAL P.C.B.

●Confirmation of firmware version and checksum

Before and after updating the firmware, check the

firmware version and checksum by using the self-

diagnostic function menu.

Start up the self-diagnostic function and select “S4.

ROM VERSION/CHECKSUM” menu.

Using the sub-menu, have the firmware version and

checksum displayed, and note them down.

(See “SELF-DIAGNOSTIC FUNCTION”)

*When the firmware version is different from

written one after updating, perform the updating

procedure again from the beginning.

●Initializing the back-up IC

(EEPROM: IC83 on DIGITAL (1) P.C.B.)

After updating the firmware, the back-up IC MUST

be initialized by the following procedure to have

proper memorization of the set up information

(soundfield parameters, system memory and tuner

presetting, etc.).

Start up the self-diagnostic function and select “S3.

FACTORY PRESET” menu. (See “SELF-DIAGNOSTIC

FUNCTION”)

Select “PRESET RSRV”, press the “MAIN ZONE ”

key to turn off the power once and turn on the power

again. Then the back-up IC is initialized.

●Required Tools

• USB storage device

• Firmware

RX-V771: RXV771-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.
