SERVICE MANUAL

Note:

When the DIGITAL P.C.B. or IC225 on DIGITAL P.C.B. is replaced, this unit will display “Internal Error” and will not operate properly. The model name and destination MUST be written to the backup IC (EEPROM: IC221 on DIGITAL P.C.B.) to have proper operation. (For details, refer to “S5. SOFT SWITCH” menu of the self-diagnostic function.)

注意：

DIGITALP.C.B. または DIGITALP.C.B. の IC225 を交換すると、“InternalError” が表示されて本機が正常に動作しなくなります。正常に動作させるために、モデル名と仕向け先をバックアップ IC（EEPROM：DIGITALP.C.B. の IC221）へ書き込む必要があります。（詳細は、ダイアグの “S5.SOFTSWITCH” メニューを参照してください。）

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.

WALL

OUTLET

• Leakage current must not exceed 0.5mA.

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

WARNING: CHEMICAL CONTENT NOTICE!

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.

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.

無鉛ハンダについて

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：

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。

■ 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.

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。
