101 2 3 4SERVICE MANUALIMPORTANT NOTICEThis 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: 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.IMPORTANT: 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.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 distributors 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.AV RECEIVERRX-V373/HTR-3065P.O.Box 1, Hamamatsu, Japan CONTENTSTO SERVICE PERSONNEL .2FRONT PANELS .34REAR PANELS .59REMOTE CONTROL PANELS .10SPECIFICATIONS / 参考仕様 . 1116INTERNAL VIEW .17SERVICE PRECAUTIONS / 時注意事項 .17DISASSEMBLY PROCEDURES / 分解手順 .1821UPDATING FIRMWARE / .2226SELF-DIAGNOSTIC FUNCTION / （自己診断機能） .2752DISPLAY DATA .5354IC DATA .5565BLOCK DIAGRAMS .6667PRINTED CIRCUIT BOARDS .6881PIN CONNECTION DIAGRAMS .82SCHEMATIC DIAGRAMS .8392REPLACEMENT PARTS LIST .93105REMOTE CONTROL .106110CONFIGURING THE SYSTEM SETTINGS .111設定変更 Note:When the following parts are replaced, the model name and destination MUST be written to the back-up IC (EEPROM: IC221 on DIGITAL P.C.B.) to have proper operation.

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 InformationComponents 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. TO SERVICE PERSONNEL Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities.WARNING: CHEMICAL CONTENT NOTICE!For U model“CAUTION”“F1501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.”For C modelCAUTIONF1501: REPLACE WITH SAME TYPE 6A, 125V FUSE.ATTENTIONF1501: UTILISER UN FUSIBLE DE RECHANGE DE MME TYPE DE 6A, 125V.WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLE本機搭載基板付接合部無鉛付。無鉛種類、修理時下記無鉛使用推奨。 Sn+Ag+Cu（錫 + 銀 + 銅） Sn+Cu（錫 + 銅） Sn+Zn+Bi（錫 + 亜鉛 + ）注意：無鉛融点温度通常鉛入比 30 40程度高、 合使用。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 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder.About lead free solder / 無鉛2RX-V373/HTR-3065RX-V373/HTR-3065RadioFans.CN 收音机爱 好者资料库 FRONT PANELSRX-V373 (U, C, R, K, A, B, G, F, L, S, H, J models)RX-V373 (T model)J modelU, C, R, K, A, B, G, F, L, S, H models3RX-V373/HTR-3065RX-V373/HTR-3065HTR-3065 (U, C, R, K, A, B, G, F, L, S, H models)HTR-3065 (T model)4RX-V373/HTR-3065RX-V373/HTR-3065 REAR PANELSRX-V373 (U, C models)RX-V373 (R, S models)RX-V373 (T model)5RX-V373/HTR-3065RX-V373/HTR-3065RX-V373 (K model)RX-V373 (A model)RX-V373 (B, G, F models)6RX-V373/HTR-3065RX-V373/HTR-3065RX-V373 (L, H models)RX-V373 (J model)HTR-3065 (U, C models)7RX-V373/HTR-3065RX-V373/HTR-3065HTR-3065 (K model)HTR-3065 (R, S models)HTR-3065 (T model)8RX-V373/HTR-3065RX-V373/HTR-3065HTR-3065 (A model)HTR-3065 (B, G, F models)HTR-3065 (L, H models)9RX-V373/HTR-3065RX-V373/HTR-3065 REMOTE CONTROL PANELSRAV463(U, C, R, K,B, G, F, L, S, H, J models)RAV462(T model)RAV461(A model)Remote control sheet10RX-V373/HTR-3065RX-V373/HTR-3065 Audio Section / 部Rated Output Power (Power Amp.
