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 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.

■ TO SERVICE PERSONNEL

1. 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 all exposed conductive surfaces are properly insulated

from supply circuits.

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

● Leakage current must not exceed 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

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 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 solder or components located inside the enclosure of this product, wash your hands

before handling food.

About lead-free solder /

Among some types of lead-free solder currently available, it

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:

1. As the melting point temperature of the lead-free solder

is about 30°C to 40°C (50°F to 70°F) higher than that of

the lead solder, be sure to use a soldering iron suitable to

each solder.

The P.C.B.s installed in this unit are soldered using the fol-

lowing solder.

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.

2. If lead solder must be used, be sure to remove lead-free

solder from each terminal section of the parts to be re-

placed and from the area around it completely before sol-

dering, or make sure that the lead-free solder and lead

solder melt together fully.

■ PREVENTION OF ELECTRO STATIC DISCHARGE

The laser diode in the traverse unit (optical pickup) may be damaged due to static electricity from clothes or the human

body. Use caution to prevent electrostatic damage when servicing or handling the laser diode.

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.

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 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 Traverse 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 not be adjusted. Do not turn the resistor.

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.

1. Removal of Front Grille

The Front Grille is fixed to the cabinet with dowels

at 6 locations. As a screwdriver (for slotted head

screw) is used for removal, use special care not to

cause damage to the cabinet.

a. Using the screwdriver inserted in the gap between

the Front Grille and the cabinet (bottom side first),

push up the Front Grille.

b. Remove the Front Grille by lifting it up.

* When installing the Front Grille, apply quick-drying

bond to the dowels and then fit them into dowel holes

for secure installation. (The Front Grille will come off

easily if its dowels are fitted into dowel holes only.)

2. Removal of Rear Panel

Remove 14 screws ( q ) in Fig. 2.

* Arrow marks ( ) are printed to identify the screws to

be removed.

* When assembling the Rear Panel, check to ensure that

the packing is not damaged so as to prevent air leakage

from occurring.
