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).

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.

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 (position 1 in on the exploded view drawing) 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.

Due to the complexity of the DVD recorder, the time to find
a defect in the recorder can become long. To reduce this
time, the recorder has been equipped with Diagnostic and
Service software (DS). The DS offers functionality to
diagnose the DVDR hardware and tests the following:
•Interconnections between components
•Accessibility of components
•Functionality of the audio and video paths
This functionality can be accessed via several interfaces:
1. End user/Dealer script interface
2. Player script interface
3. Menu and command interface
1. End User/Dealer Script Interface
1.1 Description
The End user/Dealer script interface gives a diagnosis on
a stand alone DVD recorder; no other equipment is
needed. During this mode, a number of hardware tests
(nuclei) are automatically executed to check if the recorder
is faulty. The diagnosis is simply a "fail" or "pass"
message. If the message "FAIL" appears on the display,
there is apparently a failure in the recorder. If the message
"PASS" appears, the nuclei in this mode have been
executed successfully. There can be still a failure in the
recorder because the nuclei in this mode don't cover the
complete functionality of the recorder.
■DIAGNOSTIC SOFTWARE 1.2 Contents
Hold key <PLAY> pressed
while you plug the recorder
Unplug the power cord
During the test, the following display
is shown: the counter counts down
from the number of nuclei to be run
before the test finishes. Example:
SET O.K.?
YES
NO
To exit DEALER SCRIPT, unplug the power cord
Fig. 1
The End use/Dealer script executes all diagnostic nuclei
that do not need any user interaction and are meaningful
on a standalone DVD recorder. The nuclei called in the
End user/Dealer script are the following:

2. Player Script Interface
2.1 Description
The Player script will give the opportunity to perform a test
that will determine which of the DVD recorder's modules
are faulty, to read the error log and to perform an
endurance loop test. To successfully perform the tests, the
DVD recorder must be connected to a TV set.
To be able to check results of certain nuclei, the player
script expects some interaction of the user (i.e. to approve
a test picture or a test sound). Some nuclei (e.g. nuclei
that test functionality of the DVDR module) require that a
DVD+RW disc is inserted.
Only tests within the scope of the diagnostic software will
be executed hence only faults within this scope can be
detected.
2.2 Structure of the Player Script
The player script consists of a set of nuclei testing the
hardware modules in the DVD recorder: the Display PWB,
the Digital PWB, the Analogue In/Out PWB and the DVDR
module.
Nuclei run by the player test need some user interaction;
in the next table this interaction is described. The player
test is done in two phases:
•Interactive tests: this part of the player test depends
strongly on user interaction and input to determine
nucleus results and to progress through the full test.
Reading the error log information can be useful to
determine any errors that occurred recently during
normal operation of the DVD player.
•The loop test will perform the same nuclei as the dealer
test, but it will loop through the list of nuclei indefinitely.
STEP DESCRIPTION NUCLEUS
1 Press OPEN/CLOSE and PLAY at the same time and POWER ON the recorder to start the playerscript 2
2 The local display shows FPSEGMENTS. Press PLAY to start the test. 502
First the starburst pattern is lit, then the horizontal segments are lit, followed by the vertical segments and
the last test is light all segments test. After each of the 4 tests the user has to confirm that the correct
pattern was lit.

3.3 Command Mode Interface
Set-Up Physical Interface Components
Hardware required:
•Service PC
•one free COM port on the Service PC
•special cable to connect DVD recorder to Service PC
The service PC must have a terminal emulation program
(e.g. OS2 WarpTerminal or Procomm) installed and must
have a free COM port (e.g. COM1). Activate the terminal
emulation program and check that the port settings for the
free COM port are: 19200 bps, 8 data bits, no parity, 1 stop
bit and no flow control. The free COM port must be
connected via a special cable to the RS232 port of the
DVD recorder. This special cable will also connect the test
pin, which is available on the connector, to ground (i.e.
activate test pin).
Code number of PC interface cable: 3122 785 90017
Activation
Plug the recorder to the mains and the following text will
appear on the screen of the terminal (program):
DVD Video Recorder Diagnostic Software version 84
Basic SDRAM Data bus test passed
Basic SDRAM Address bus test passed
Basic SDRAM Device test passed
(M) enu, (C) ommand or (S) 2B-interface? [M] : @ C
DD:>
Fig. 7
The first line indicates that the Diagnostic software has
been activated and contains the version number. The next
lines are the successful result of the SDRAM
interconnection test and the basic SDRAM test. The last
line allows the user to choose between the three possible
interface forms. If pressing C has made a choice for
Command Interface, the prompt ("DD>") will appear. The
diagnostic software is now ready to receive commands.
The commands that can be given are the numbers of the
nuclei.
