SERVICE MANUAL100922IMPORTANT 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.P.O.Box 1, Hamamatsu, JapanI CONTENTSTO SERVICE PERSONNEL . 2FRONT PANELS. 34REAR PANELS . 47REMOTE CONTROL. 7SPECIFICATIONS / 参考仕様 . 810INTERNAL VIEW . 11DISASSEMBLY PROCEDURES / 分解手順. 1215UPDATING FIRMWARE /書込. 1617SELF DIAGNOSIS FUNCTION (DIAG) /自己診断機能（）. 1842AMP ADJUSTMENT / 部調整 . 43DISPLAY DATA . 44IC DATA . 4548BLOCK DIAGRAM. 4950PIN CONNECTION DIAGRAM . 51PRINTED CIRCUIT BOARD . 5269SCHEMATIC DIAGRAM . 7181PARTS LIST. 83119REMOTE CONTROL. 120AV RECEIVER/AV AMPLIFIERRX-V2500/DSP-AX2500RX-V2500/DSP-AX2500 04.11RadioFans.CN 收音机爱 好者资料库RX-V2500/DSP-AX25002RX-V2500/DSP-AX2500WALLOUTLETEQUIPMENTUNDER 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”“F2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A,125V FUSE.”CAUTIONF2: REPLACE WITH SAME TYPE 10A, 125V FUSE.ATTENTIONF2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.About lead-free solder / 無鉛The P.C.B.s installed in this unit are soldered using thefollowing solder.本機搭載基板付使用下記通。Side ASide BSMT REFLOW ProcessMI FLOW ProcessSolder Dip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3040程度高、合使用。 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 solderis about 30C to 40C (50F to 70F) higher than that ofthe lead solder, be sure to use a soldering iron suitableto each solder.2. If lead solder must be used, be sure to remove lead freesolder from each terminal section of the parts to bereplaced and from the area around it completely beforesoldering, or make sure that the lead-free solder andlead solder melt together fully.DSP P.C.B.FUNCTION P.C.B.OPERATION P.C.B.MAIN P.C.B.POWER PC.B.INPUT P.C.B.CONTROL P.C.B.Side A / A 面Lead Solder / 鉛入Lead Solder / 鉛入Lead Solder / 鉛入Lead Solder / 鉛入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Lead Free Solder / 無鉛Lead Free Solder / 無鉛RadioFans.CN 收音机爱 好者资料库RX-V2500/DSP-AX25003RX-V2500/DSP-AX2500I FRONT PANELSRX-V2500 (U, C, A models)RX-V2500 (R, T, K, L models)RX-V2500 (B, G models)RX-V2500/DSP-AX25004RX-V2500/DSP-AX2500 REAR PANELSRX-V2500 (U, C models)DSP-AX2500 (J model)RX-V2500 (R model)RX-V2500/DSP-AX25005RX-V2500/DSP-AX2500RX-V2500 (K model)RX-V2500 (A model)RX-V2500 (T model)RX-V2500/DSP-AX25006RX-V2500/DSP-AX2500RX-V2500 (B model)RX-V2500 (G model)RX-V2500 (L model)RX-V2500/DSP-AX25007RX-V2500/DSP-AX2500DSP-AX2500 (J model)I REMOTE CONTROLRX-V2500 (U, C, R, T, K, A, L models)DSP-AX2500 (J model)RX-V2500 (B, G models)RX-V2500/DSP-AX25008RX-V2500/DSP-AX2500I SPECIFICATIONS / 参考仕様I Audio Section / 部Minimum RMS Output Power (Power Amp.
