CDR-S1000 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 inherant 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 all 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 accumu-
lated 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 parts replacement. Recheck all work before you apply power to the unit.

s TO SERVICE PERSONNEL
1. Critical Components Information
AC LEAKAGE
Components having special characteristics are marked Z WALL EQUIPMENT TESTER OR
and must be replaced with parts having specifications equal OUTLET UNDER TEST EQUIVALENT
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. INSULATING
TABLE
q Meter impedance should be equivalent to 1500 ohm shunted
by 0.15µF.
q Leakage current must not exceed 0.5mA. q 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.

· 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

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.

4pin (+5V) 5.0 ± 0.25V +5V power supply (CDR drive)
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.
