SERVICE MANUAL
AX-V765
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. Modifications 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
2. Leakage Current Measurement (For 120V Models Only)
• Meter impedance should be equivalent to 1500 ohms shunted
Components having special characteristics are marked ⚠ and must be replaced with parts having specifications equal to those originally installed.
When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits.
by 0.15 μF.
For U model
“CAUTION”
“F3701: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A,
125V FUSE.”
For C model
CAUTION
F3701: REPLACE WITH SAME TYPE 10A, 125V FUSE.
ATTENTION
F3701: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 10A, 125V.

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 positions 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, perform discharge by connecting a discharge resistor (5k-ohms/10W) between terminals at following positions. The time required for discharging is about 30 seconds.
C3703 on VIDEO (2) P.C.B. Refer to “PRINTED CIRCUIT BOARDS: VIDEO (2)
P.C.B.”.
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。
・ 下記箇所には電源を 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)を下記箇所の 端子間に接続して放電してください。 放電所用時間は約 30 秒間です。
