1、SERVICE MANUAL This 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 already known and understood by the users, and have therefore no

2、t 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 specified. For these reasons, we advise all YAMAHA product owners that any ser

3、vice 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 firm does not constitute authorization, certification or recognition of any applicable technical capabilities, or establi

4、sh 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

5、 and specifications are subject to change without notice or obligation to retrofit. 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

6、 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. IMPORTANT NOTICE 101004 SERVICE MANUAL DV-C6860 DVD PLAYER 2006 All rights rese

11、. Critical Components Information Components having special characteristics are marked Z 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 a

12、ll exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohms shunted by 0.15F. GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities. WARNING: CHEMICAL CONTENT NOTICE! The solder used

13、 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 Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other r

14、eproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with s

15、older or components located inside the enclosure of this product, wash your hands before handling food. WARNING: Laser Safety This product contains a laser beam component. This component may emit invisible, as well as visible radia-tion, which may cause eye damage. To protect your eyes and skin from

16、 laser radiation, the following pre-cautions must be used 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 from the laser pick-up unit at all times. Do not stare at the laser beam at any time. 2) Do not atte

17、mpt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION : Use of controls, adjustments or perform-ance of procedures other than those specified herein may result in hazardous radiation exposure. Laser Emitting conditions: 1) When the Top Cover is r

18、emoved, and the STANDBY/ ON SW is turned to the “ON” position, the laser compo-nent will emit a beam for several seconds to detect if a disc is present. During this time (510 sec.) the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period! If n

19、o disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser emissions. 2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory prior to shipping from the factory. Do not adjust

20、 this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this con-trol can increase the laser emission level from the device.

22、LET RadioFans.CN 收音机爱 好者资料库 DV-C6860 3 DV-C6860 WARNING The 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 supply The primary side of the power supply carries live ma

23、ins voltage when the player is connected to the mains even when the 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

24、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. CLASS 1 LASER PRODUCT LASER KLASSE 1 PRODUKT LUOKAN 1 LASERLAITE

If the Locale number described on the DVD disc does not correspond to the Locale number of this DVD player, this DVD player cannot play this disc. I PREVENTION OF ELECTROSTATIC DISCHARGE The laser diode in the DVD mechanism may be damaged du

31、e to static electricity from clothes or the human body. Use caution to prevent electrostatic damage when servicing or handling the DVD-mechanism. 1. Grounding for electrostatic damage prevention 1. Worktable grounding Put a grounded conductive material (sheet) or iron sheet on the area where the opt

32、ical pickup is placed. 2. Human body grounding Use an anti-static wrist strap to discharge the static electricity from your body. 2. Handling of the optical pickup 1. To prevent damage to the optical pickup replacement parts during transportation and before installation,both ends of the laser diode

33、are short-circuited.After installing the new part,remove the short circuit according to the correct procedure in this service manual. 2. Do not use a tester to check the laser diode in the optical pickup.The power supply in the tester will damage the laser diode. 3. Handling Precautions for the Trav

34、erse Unit (Optical Pickup) 1. Handle the traverse unit (optical pickup)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

35、not be adjusted.Do not turn the resistor. 1M Conductive material (sheet) or steel sheet Anti-static wrist strap DV-C6860 5 DV-C6860 I REAR PANEL I FRONT PANEL I REMOTE CONTROL DV-C6860 6 DV-C6860 I SPECIFICATIONS G PLAYBACK SYSTEM DVD-Video Video CD & SVCD CD PICTURE CD CD-R, CD-RW DVD+R, DVD+RW DVD
