SERVICE 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 specifically YAMAHAProducts, 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 productmay result in personal injury, destruction of expensive components, and failure of theproduct to perform as specified. For these reasons, we advise all YAMAHA productowners that any service required should be performed by an authorized YAMAHARetailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual of firm does not constituteauthorization, certification 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 specifications are subject to change without notice or obligationto retrofit. Should any discrepancy appear to exist, please contact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricityyour 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 beforeyou apply power to the unit.100796AV RECEIVERRX-V320TO SERVICE PERSONNEL . 1REMOTE CONTROL PANEL . 1FRONT PANEL . 2REAR PANEL . 2SPECIFICATIONS. 34INTERNAL VIEW . 4DISASSEMBLY PROCEDURES . 5SELF DIAGNOSIS FUNCTION . 617FACTORY PRESET . 18ICONTENTSAMP ADJUSTMENT . 19TUNER ADJUSTMENT.2023IC DATA .2432DISPLAY DATA . 33BLOCK DIAGRAM. 3437PRINTED CIRCUIT BOARD . 3853SCHEMATIC DIAGRAM . 5460PARTS LIST .6174REMOTE CONTROL TRANSMITTER .7576For T modelRadioFans.CN 收音机爱 好者资料库1RX-V320I TO SERVICE PERSONNEL1. Critical Components informationComponents having special characteristics are marked Z and must be replaced with parts having specifications equal to those originallyinstalled.2. Leakage Current Measurement (For 120V Model only)When service has been completed, it is imperative that you verify thatall exposed conductive surfaces are properly insulated from supplycircuits.Meter impedance should be equivalent to 1500 ohm shunted by 0.15F.Leakage current must not exceed 0.5mA.Be sure to test for leakage with the AC plug in both polarities.WARNING: 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 (and possiblyother 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 REASONWHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyesto solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handlingfood.I REMOTE CONTROL PANELWALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLETUNERAMPTAPE/MDCBL/SATCDTVVCRDVD/LDDVDMENUPOWER2TUNER3TAPE/MD1CD5SAT/D-TV6VCR4DVD/LD8V-AUX9EXT.DEC.7PHONOENTER+10CLEAR+1000A/B/C/D/EMUTEPRG +PRG -TVSELECTDIR ADIR BDISC SKIPPRESETEFFECTCHTESTDISPINDEXSLEEPRETURNA/BTV INPUTVCR RECMENUTITLE+-SET MENUTIME/LEVELRAV203V473170 US-CHCODESETVOLUMETVRadioFans.CN 收音机爱 好者资料库2RX-V320I FRONT PANELI REAR PANEL3RX-V320T .
