1、SERVICE MANUAL 101038 IMPORTANT NOTICE 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 user

2、s, and have therefore not 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 pro

3、duct owners that any service 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

4、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 ar

5、e, therefore, inevitable 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

6、 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.

I TO SERVICE PERSONNEL 本機搭載基板付接合 部無鉛付。 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。 All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder. Among some types of lead free solder currently available, it

15、is recommended to use one of the following types for the repair work. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder

16、, be sure to use a soldering iron suitable to each solder. About lead free solder / 無鉛 WARNING: Laser Safety This 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,

17、the following precautions 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 attempt to readjust, di

18、sassemble 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 in hazardous radiation exposure. RadioFans.CN 收音机爱 好者资料库 DVD-S2700 3 DVD-S2700 Laser Emitting conditions:

19、1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the ON position, the laser component will emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing d

20、uring 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 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

21、 factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device.

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 hum

25、an body. Use caution to prevent electrostatic damage when servicing or handling the DVD-mechanism. 1. Grounding for electrostatic damage prevention Some devices, such as the DVD player, use an optical pickup (laser diode) that will be damaged by static electricity in the working environment. Only at

26、tempt service after ensuring that all grounding procedures have been completed. 1. Worktable grounding Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed. 2. Human body grounding Use an anti-static wrist strap to discharge the static electricity f

27、rom your body. 2. Handling Precautions for DVD mechanism 1. 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 ad

28、justment should not be adjusted. Do not turn the resistor. I LOCALE MANAGEMENT INFORMATION Locale Management Information : This DVD player is designed and manufactured to respond to the Locale Management Information that is recorded on a DVD disc. If the Locale number described on the DVD disc does

29、not correspond to the Locale number of this DVD player, this DVD player cannot play this disc. Warning for power supply The primary side of the power supply carries live mains voltage when the player is connected to the mains even when the player is switched off ! This primary area is not shielded s

30、o 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

31、care when the unit has to be exchanged! The DVD mechanism is very sensitive for dropping or giving shocks. 1M-ohms Conductive material (sheet) or steel sheet Anti-static wrist strap 1 4 2 2 2 5 5 5 4 3 6 DVD-S2700 5 DVD-S2700 I FRONT PANEL U, T, A, G, J models I REAR PANELS U model T model DVD-S2700
