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 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 product 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 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 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 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.

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 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 expose eyes to solder/flux vapor! If you come in contact with solder 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 radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, 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, 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 in hazardous radiation exposure. 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 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 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 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 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. WALL OUTLET EQUIPMENT UNDER TEST AC LEAKAGE TESTER OR EQUIVALENT INSULATING TABLE I TO SERVICE PERSONNEL 1. Critical Components Information Components having special characteristics are marked s 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 all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohm shunted by 0.15F. CAUTION 1110: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 2A, 250V FUSE. CAUTION 1110: REPLACE WITH SAME TYPE 2A, 250V FUSE. ATTENTION 1110: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 2A, 250V. GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities. THE DVD AUDIO/VIDEO RECEIVER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED SERVICE PERSONNEL.

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 . The primary side of the power supply has been indicated with a lightening stroke and a stripe-marked print on the printed wiring board Note: The screws on the DVD mechanism (position 9 in on the exploded view drawing) 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.

I PREVENTION OF ELECTRO STATIC DISCHARGE The laser diode in the DVD mechanism may be damaged due 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 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 attempt 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 from your body. 1M Conductive material (sheet) or steel sheet Anti-static wrist strip 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 adjustment should not be adjusted. Do not turn the resistor.

The schematic provided in the manual is only for information and no service parts will be available. G DVD Mechanism 1. The DVD mechanism is not a repairable unit and in case of failure, it has to be replaced with a new DVD mechanism. Note: When replacing with a new DVD mechanism, two solder joints have to be removed after connecting the OPU flex foil to the mono board. The solder joints, which shortcircuits the laser diodes to ground, are for protection
