SERVICE MANUAL101050SERVICE MANUALP.O.Box 1, Hamamatsu, JapanSERVICE 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 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 . 23PREVENTION OF ELECTROSTATIC DISCHARGE . 4LOCALE MANAGEMENT INFORMATION . 4FRONT PANELS. 5REAR PANELS . 5-6REMOTE CONTROL PANEL . 6SPECIFICATIONS. 67INTERNAL VIEW . 8REPAIR NOTES. 9TRADE MODE. 9 2007 All rights reserved.This manual is copyrighted by YAMAHA and may not be copied orredistributed either in print or electronically without permission.DVD-S661/DV-S6160 07.05This service manual is for the DVD-S661/DV-S6160 (U, K, A, L, P models).For the DVD-S661 (G model) service manual, please refer to the following service manual:DVD-S661 (G model): 101047For U, K, A, L, P modelsDISASSEMBLY PROCEDURES . 10TEST MODE . 11BLOCK DIAGRAM. 12WIRING DIAGRAM . 13PRINTED CIRCUIT BOARDS. 1419SCHEMATIC DIAGRAMS. 2026REPLACEMENT PARTS LIST . 2829REMOTE CONTROL. 29SCENE CONTROL. 30DVD-S661/DV-S6160DVD PLAYERRadioFans.CN 收音机爱 好者资料库DVD-S661/DV-S6160DVD-S661/DV-S61602WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEI TO SERVICE PERSONNEL1. Critical Components InformationComponents having special characteristics are marked Zand 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 ohms shuntedby 0.15F.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polari-ties.WARNING: Laser SafetyThis product contains a laser beam component. This component may emit invisible, as well as visible radiation,which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must beused during servicing of the unit.1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away fromthe laser pick-up unit at all times. Do not stare at the laser beam at any time.2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result inhazardous radiation exposure.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic(where applicable) components may also contain traces of chemicals found by the California Health and WelfareAgency (and possibly 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 ANYREASON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes orexpose eyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your handsbefore handling food.Laser Emitting conditions:1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the ON position, the laser component will emita beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through thelens of the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laseremissions.2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factoryprior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.Laser Diode PropertiesType:Semiconductor laser GaAlAsWave length:650 nm (DVD)780 nm (VCD/CD)Output Power:7 mW (DVD)10 mW (VCD/CD)Beam divergence:60 degreeRadioFans.CN 收音机爱 好者资料库DVD-S661/DV-S61603DVD-S661/DV-S6160WARNINGThe use of optical instruments with this product will increase eye hazard.Repair handling should take place as much as possible with a disc loaded inside the player.Warning for power supplyThe primary side of the power supply carries live mains voltage when the player is connected to the mains even whenthe player is switched off !This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.Service personnel have to take precautions to prevent touching this area or components in this area.Note:The screws on the DVD mechanism may never be touched, removed or re-adjusted.Handle the DVD mechanism with care when the unit has to be exchanged!The DVD mechanism is very sensitive for dropping or giving shocks.DVD-S661/DV-S6160DVD-S661/DV-S6160414222555436I PREVENTION OF ELECTROSTATIC DISCHARGEThis product incorporates copyright pro-tection technology that is protected bymethod claims of certain U.S. patents andother intellectual property rights owned byMacrovision Corporation and other rightsowners. Use of this copyright protectiontechnology must be authorized byMacrovision Corporation, and is intendedfor home and other limited viewing usesonly unless otherwise authorized byMacrovision Corporation. Reverse engineer-ing or disassembly is prohibited.The laser diode in the DVD mechanism may be damaged due to static electricity from clothes or the human body. Use cautionto prevent electrostatic damage when servicing or handling the DVD-mechanism.1. Grounding for electrostatic damage preventionSome devices, such as the DVD player, use an optical pickup (laser diode) that will be damaged by static electricity in theworking environment. Only attempt service after ensuring that all grounding procedures have been completed.1. Worktable groundingPut a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.2. Human body groundingUse an anti-static wrist strap to discharge the static electricity from your body.1M-ohmsConductive material(sheet) or steel sheetAnti-static wrist strap2. Handling Precautions for DVD mechanism1. Handle the DVD mechanism gently, as it is an extremely high-precision assembly.2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.I LOCALE MANAGEMENT INFORMATIONLocale Management Information : This DVD player is designed and manufactured to respond to the LocaleManagement Information that is recorded on a DVD disc.
