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.

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 the laser beam at any time.

2) Do not attempt readjustment, disassemble or repair of the laser pick-up, unless noted elsewhere in this manual.

3) CAUTION : Use of controls, adjustments or preformance of procedures other than those specified herein may result in

hazardous radiation exposure.

Laser Emitting conditions:

1) When the Top Cover is removed, and POWER 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 set, you will not be exposed to any laser
emissions.

2) The laser power level can be adjusted with VR on 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 instruuction is provided elsewhere in this manual.
Adjustment of this control can increase the laser emission level from the device.

■ DISASSEMBLY PROCEDURES (Remove parts in disassembly order as numbered.)

CDR MECHANICAL UNIT REPLACEMENT

• When sending back the defective CDR mechanical unit for repair, send the whole unit.

• The CDR mechanical unit must be replaced as a unit. None of its components can be supplied separately.

• When sending back the defective CDR mechanical unit for repair, attach the disc which was used when the error

occurred as necessary . However, Yamaha shall not be liable even if the data in the disc has become unreadable while
the unit is being serviced/repaired.

Preparation before Replacement

a. When replacing the CDR mechanical unit, write down the following items.

• Serial No. of the product and the symptom in detail

• Mechanical serial No. / mechanical shipping serial No. of CDR mechanical unit

b. Prepare a lens cover (P/No. V4870500) to use when transporting the CDR mechanical unit.

3. CDR Mechanical Unit Installation

a. Before installing the CDR mechanical unit, check that

CDR-S1000

the jumper pin on its rear panel is inserted in the MAS­TER jack.

MASTER

b. Install the components of the CDR mechanical unit cor-

rectly in the reverse order of the removal.

c. Use special care for the power cable of the CDR me-

chanical unit. If it is connected in reverse, the mechani­cal unit will be damaged and fail to operate.
The end of the power cable with a red line is the No.1
pin side (+12V). Connect it to No.1 pin of the DC power
input connector.

d. The No.1 pin side of the IDE cable of the CDR mechani-

cal unit can be identified by a red line. Connect it to
No.1 pin of the IDE interface connector.

4. Operation Check after Installation

1) Checking after turning on the power

When the power is supplied, the CDR mechanical unit
executes self-diagnosis automatically.
If an error is detected in the initial self-diagnosis, LED
segments (LED601: ON/DISC, LED602: Read/Write) on
the front panel of the mechanical unit light up (in or­ange) simultaneously and remain on.
If a malfunction has occurred, power on fails. (IDE com­mand error)

2) Checking when malfunction has occurred

a. Check each cable for correct connection.
b. Check the power supply voltages. (Measure voltage at

the power connector of the mechanical unit.)

c. Check to ensure that the jumper pin on the rear panel is

inserted in the MASTER jack.

Remarks

2. Turn off the power to check the condition of the CDR drive section.

3. Disconnect the IDE cable.

4. Turn on the power and check the CDR drive section for proper operation.

(Check the condition of the CDR drive.)

The CDR drive should operate by itself.

(Focusing, disc motor revolution)

Operation failure means defective CDR drive.

5. Turn on the power again and check the CPU and FL display for proper operation.

Does the FL display light up after a few seconds?

Is the FL driver accessed?

(FL DATA, FL SCK, FL N CS)

6. Turn off the power and connect the IDE cable.

7. Start the TEST program and check the condition of the main P.C.B.(by using the self-

diagnosis function).

When skipping occurs from time to time, playback/recording is disabled.

1. Using a standard disc (TDK CD-RXA74 or TDK CD-RWXA74), check if recording and playback are executable.

CAUTION: How to handle discs

• Handle the disc with special care not to scratch it or make it dirty. Also do not expose it to ultra-violet rays when keeping it in

storage. (Greater care should be used than when handling a CD disc.)

• CD-RW74 can be used repeatedly but use a number of 20 times as a rough standard for the limit.

• If the CD-R is a self-record/playback type, it can be reused (for additional recording) unless it is finalized.

(Nothing can be recorded additionally if finalized.)
The CD-R disc which has not been finalized cannot be played back on a general type CD player..

• To play back the CD-RW, an applicable type CD player must be used.

INPUT selector (at CD STOP)

• Selects the input signal.

• The selected input signal passes through DSP3 and is output to LINE

OUT (Analog) and DIGITAL OUT (Digital). Also, the level meter read­ing is displayed in response to the input signal.

• In case of the digital signal, the sampling frequency is read from the
channel status and displayed as 32, 44.1 or 48 (kHz).

• When the subcode Q data is included in the digital signal, a part of
the subcode Q data appears on the FL display.

CD DIRECT key (at CD STOP)

• Selects the digital input signal passage, whether through SRC (Sample
Rate Converter) or direct. CD DIRECT LED lights up when the direct
signal passage is selected but this does not apply when the sampling
frequency is other than 44.1kHz ± 200ppm.

The output level of the digital signal (optical/coaxial) should be
checked by using the relative value of the analog demodulated
signal.

REC LEVEL control knob

• When the digital input is selected, SRC is activated as the digital
volume controller.
If CD DIRECT is selected, however, the digital volume is set to through
(0dB) state.

• When the analog input is selected, this control knob functions as the
analog volume control.

DISPLAY key
Turns on and off all the display units.
To cancel the all on or off state of display units, press the ERASE key
and the original display state will be restored.
