SERVICE MANUAL100998IMPORTANT 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 specifically YAMAHA Products, are alreadyknown 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 personalinjury, 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 authorizedYAMAHA Retailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitute authorization, certification orrecognition 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, andservice departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitableand specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, pleasecontact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may haveaccumulated 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.I CONTENTSTO SERVICE PERSONNEL . 23FRONT PANELS. 35REAR PANELS . 59REMOTE CONTROL PANELS. 10SPECIFICATIONS / 参考仕様 . 1112INTERNAL VIEW . 13DISASSEMBLY PROCEDURES / 分解手順 . 1415SELF DIAGNOSIS FUNCTION (DIAG) /自己診断機能 （） . 1637AMP ADJUSTMENT / 部調整 . 38DISPLAY DATA . 3940IC DATA . 4150PIN CONNECTION DIAGRAM . 5152BLOCK DIAGRAMS . 5355PRINTED CIRCUIT BOARDS. 5668SCHEMATIC DIAGRAMS. 6975REPLACEMENT PARTS LIST . 7795REMOTE CONTROL. 9697ADVANCED SETUP . 98REPLACEMENT PARTS LIST FOR CARBON RESISTORS.99P.O.Box 1, Hamamatsu, JapanAV RECEIVER/AV AMPLIFIERRX-V459/HTR-5940/DSP-AX459HTR-5935RX-V459/HTR-5940/DSP-AX459HTR-5935 2006 All rights reserved.This manual is copyrighted by YAMAHA and may not be copied orredistributed either in print or electronically without permission. 06.02RadioFans.CN 收音机爱 好者资料库RX-V459/HTR-5940/DSP-AX459HTR-59352RX-V459/HTR-5940/DSP-AX459HTR-5935WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEWARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (andpossibly other entities) to cause cancer and/or birth defects or other reproductive harm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-SON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.I TO SERVICE PERSONNEL1. Critical Components InformationComponents having special characteristics are marked sand must be replaced with parts having specifications equalto those originally installed.2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.GMeter impedance should be equivalent to 1500 ohmsshunted by 0.15F.“CAUTION”“F3000, 3001: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE8A, 125V FUSE.”CAUTIONF3000, 3001: REPLACE WITH SAME TYPE 8A, 125V FUSE.ATTENTIONF3000, 3001: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 8A, 125V.本機搭載基板付使用下記通。The P.C.B.s installed in this unit are soldered using thefollowing solder.About Lead Free Solder / 無鉛Side ASide BSMT REFLOW ProcessMI FLOW ProcessSolder DipGLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.DSP P.C.B.FUNCTION P.C.B.OPERATION P.C.B.MAIN P.C.B.YST P.C.B.SIDE A / A面lead free solder / 無鉛SIDE B / B面lead free solder / 無鉛lead free solder / 無鉛lead free solder / 無鉛lead free solder / 無鉛lead free solder / 無鉛RadioFans.CN 收音机爱 好者资料库RX-V459/HTR-5940/DSP-AX459HTR-59353RX-V459/HTR-5940/DSP-AX459HTR-5935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：1. 無鉛融点温度通常鉛入比3040程度高、合使用。2. 鉛入使得場合、交換部品端子部周辺部無鉛取除、無鉛鉛入十分溶状態付。Among some types of lead free solder currently available,it is recommended to use one of the following types for therepair 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 isabout 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.2. If lead solder must be used, be sure to remove lead free solderfrom each terminal section of the parts to be replaced andfrom the area around it completely before soldering, or makesure that the lead free solder and lead solder melt togetherfully.I FRONT PANELSRX-V459 (U, C models)RX-V459 (R, T, K, A, G, E, L models)RX-V459/HTR-5940/DSP-AX459HTR-59354RX-V459/HTR-5940/DSP-AX459HTR-5935HTR-5940 (T, K, A, G, E models)DSP-AX459 (J model)HTR-5940 (U, C models)RX-V459/HTR-5940/DSP-AX459HTR-59355RX-V459/HTR-5940/DSP-AX459HTR-5935RX-V459 (U, C models)I REAR PANELSRX-V459 (R model)HTR-5935 (U model)RX-V459/HTR-5940/DSP-AX459HTR-59356RX-V459/HTR-5940/DSP-AX459HTR-5935RX-V459 (A model)RX-V459 (K model)RX-V459 (T model)RX-V459/HTR-5940/DSP-AX459HTR-59357RX-V459/HTR-5940/DSP-AX459HTR-5935RX-V459 (G, E models)RX-V459 (L model)HTR-5940 (U, C models)RX-V459/HTR-5940/DSP-AX459HTR-59358RX-V459/HTR-5940/DSP-AX459HTR-5935HTR-5940 (A model)HTR-5940 (T model)HTR-5940 (K model)RX-V459/HTR-5940/DSP-AX459HTR-59359RX-V459/HTR-5940/DSP-AX459HTR-5935HTR-5935 (U model)HTR-5940 (G, E models)DSP-AX459 (J model)RX-V459/HTR-5940/DSP-AX459HTR-593510RX-V459/HTR-5940/DSP-AX459HTR-5935RAV322I REMOTE CONTROL PANELSRAV323RX-V459 (U, C models)HTR-5940 (U, C models)DSP-AX459 (J model)RX-V459 (R, T, K, A, G, E, L models)HTR-5940 (T, K, A, G, E models)HTR-5935 (U model)RAV307RAV30811RX-V459/HTR-5940/DSP-AX459HTR-5935 DIMENSIONS / 寸法図I General / 総合Power Supply / 電源電圧U, C models .AC 120 V, 60 HzR model .AC 110/120/220/230-240 V, 50/60 HzT model.AC 220 V, 50 HzK model.AC 220 V, 60 HzA model.AC 240 V, 50 HzG, E models .AC 230 V, 50 HzL model .
