RX-V557/HTR-5850/DSP-AX557

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 s
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

RX-V557/HTR-5850/DSP-AX557

RX-V457/HTR-5840/DSP-AX457

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.

“CAUTION”

“F1, 2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 8A, 125V FUSE.”

CAUTION

F1, 2: REPLACE WITH SAME TYPE 8A, 125V FUSE.

ATTENTION

F1, 2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 8A, 125V.

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.

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:

1. 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.

2. If lead solder must be used, be sure to remove lead free solder
from each terminal section of the parts to be replaced and
from the area around it completely before soldering, or make
sure that the lead free solder and lead solder melt together
fully.

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：

① 無鉛ハンダの融点温度は通常の鉛入りハンダに比べ30〜40℃

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。

② 鉛入りハンダを使わざるを得ない場合は、あらかじめ交換する

部品端子部やその周辺部の無鉛ハンダをすべて取り除くか、あ
るいは無鉛ハンダと鉛入りハンダが十分に溶けた状態となるよ

When checking the P.C.B.:

• Put a Cloth over the equipment. Put the MAIN (1), (5), and

POWER (1), (2) P.C.B.s together with the heat sink upright

on the Cloth and check them. (Fig. 6)

• Reconnect all cables (connectors) that have been

disconnected.

• When connecting the flat cable, use care for the polarity.

• The P.C.B. removed from the rear panel does not work

because its grounding is loose. Be sure to connect the

ground of each P.C.B. to the chassis or GND with a jumper

wire or the like.
