SERVICE MANUAL

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 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 distributor's 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.

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 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.

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 mains 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 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 DVDR mechanism may never be touched, removed or re-adjusted.

Handle the DVDR mechanism with care when the unit has to be exchanged!

The DVDR mechanism is very sensitive for dropping or giving shocks.

PREVENTION OF ELECTRO STATIC DISCHARGE

The laser diode in the DVDR 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 DVDR mechanism.

1. Grounding for electrostatic damage prevention

Some devices, such as the DVD recorder, 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.

Anti-static wrist strap

Conductive material

(sheet) or iron sheet

2. Handling Precautions for DVDR mechanism

1. Handle the DVDR 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.

LOCALE MANAGEMENT INFORMATION
