1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
such as Simpson Model 229-2 or equivalent between the
earth ground and all exposed metal parts of the appliance
(input/output terminals, screwheads, metal overlays,
control shaft, etc.). Plug the AC line cord of the appliance
directly into a 120V AC 60Hz outlet and turn the AC power
switch on. Any current measured must not exceed 0.5mA.
Reading should
not be above
0.5mA
Earth

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED
BEFORE RETURNING THE APPLIANCE TO THE
CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are
often not evident from visual inspection nor the
protection afforded by them necessarily can be obtained
by using replacement components rated for voltage,
wattage, etc. Replacement parts which have these
special safety characteristics are identified in this Service
Manual.
Electrical components having such features are identified
by marking with a
list in this Service Manual.
The use of a substitute replacement component which does
not have the same safety characteristics as the MARANTZ
recommended replacement one, shown in the parts list in
this Service Manual, may create shock, fire, or other
hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current MARANTZ Service
Manual. A subscription to, or additional copies of,
MARANTZ Service Manual may be obtained at a nominal
charge from MARANTZ.

3. SERVICING PRECAUTIONS
CAUTION : Before servicing the DVD covered by this service
data and its supplements and ADDENDUMS, read and follow
the
SAFETY PRECAUTIONS. NOTE
circumstances create conflict between the following servicing
precautions and any of the safety precautions in this
publications, always follow the safety precautions.
: if unforeseen
Remember Safety First:
General Servicing Precautions
1. Always unplug the DVD AC power cord from the AC
power source before:
(1) Removing or reinstalling any component, circuit board,
module, or any other assembly.
(2) Disconnection or reconnecting any internal electrical
plug or other electrical connection.
(3) Connecting a test substitute in parallel with an elec-
trolytic capacitor.
Caution : A wrong part substitution or incorrect
polarity installation of electrolytic capacitors may result
in an explosion hazard.
2. Do not spray chemicals on or near this DVD or any of
its assemblies.
3. Unless specified otherwise in this service data, clean
electrical contacts by applying an appropriate contact
cleaning solution to the contacts with a pipe cleaner,
cotton-tipped swab, or comparable soft applicator.
Unless specified otherwise in this service data, lubrication
of contacts is not required.
4. Do not defeat any plug/socket B+ voltage interlocks with
which instruments covered by this service manual might
be equipped.
5. Do not apply AC power to this DVD and/or any of its
electrical assemblies unless all solid-state device heat
sinks are correctly installed.
6. Always connect test instrument ground lead to the
appropriate ground before connection the test instrument
positive lead. Always remove the test instrument ground
lead last.
Insulation Checking Procedure
Disconnect the attachment plug from the AC outlet and turn
the power on. Connect an insulation resistance meter(500V)
to the blades of the attachment plug. The insulation resistance
between each blade of the attachment plug and accessible
conductive parts (Note 1) should be more than 1M-ohm.
Note 1 : Accessible Conductive Parts including Metal panels,
Input terminals, Earphone jacks, etc.
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of
typical ES devices are integrated circuits and some field effect
transistors and semiconductor chip components.
The following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known
earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which
should be removed for potential shock reasons prior to
applying power to the unit under test.
2. After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface such
as aluminum foil, to prevent electrostatic charge buildup or
exposure of the assembly.
3. Use only a GROUNDED-tip soldering iron to solder or
unsolder ES devices.
4. Use only an anti-static solder removal device. Some
solder removal devices not classified a “anti-static” can
generate electrical charges sufficient to damage ES
devices.
5. Do not use freon-propelled chemicals. These can
generate electrical charge sufficient to damage ES
devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to
install it. (Most replacement ES devices are packaged with
leads electrically shorted together by conductive foam,
aluminum foil, or comparable conductive material).
7. Immediately before removing the protective material from
the leads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into which the
device will be installed.
Caution : Be sure no power is applied to the chassis or
circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged
replacement ES devices. (Normally harmless motion such
as the brushing together of your clothes fabric or the lifting
of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device.)

DVD INFORMATION
Below is a glossary of the new terms related to DVD.
Multi-angles:
On some DVDs, scenes have been filmed from different angles
(up to a maximum of 9). On these discs, you can select the
angle that you want to watch. Please refer to the DVD’s manual
to see which scenes have multi-angles.
Parental guide:
Some discs have restriction levels that allow you to cut scenes
or prevent playback of discs that have contents that you do
not want children to watch.
Title:
A disc may have more than one story/movie on it, so each
story/movie is called a “title”.
For example, if there are 2 movies on the disc, they are
separated into Title 1 and Title 2.
Chapter:
A title may also be separated into chapters.
For example, a movie (title) may be separated into 3 scenes
(chapters).
Title 1Title 2
Chapter1Chapter
Subtitles:
DVDs are recorded with up to 32 different subtitle languages.
If a disc has more than one subtitle language, you can select
the subtitle language that you want to read.
Soundtrack language:
DVDs are recorded with up to 8 different soundtrack languages.
If a disc has more than one language, you can select the
soundtrack language that you want to listen to.

6. REGIONAL CODES
What are "regional codes"?
Motion picture studios want to control the home release of movies in different countries because theater releases arenít
simultaneous (a movie may come out on DVD in the US when itís just hitting screens in Europe). Therefore they have
required that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geographical regions. Players sold in each region will have that regionís code built into the player. The player will refuse to play
these "region coded" discs which are not allowed in the region. However, regional codes are entirely optional. Discs without
codes will play on any player in any country. Some studios have already announced that only their new releases will have
regional codes. There are six regions:
1. United States and Canada
2. Europe and Japan
3. Far East (except Japan & China)
4. South America and Oceania
5. Africa and the Middle East
6. China (except Hong Kong)

(Check the each voltage.)
• FL controller IC (IC701) on the FLKY Assy is damaged.
The protocol system is based on a system in which the computer
gives commands and the player returns statuses. The communication
protocol used conforms to that used by industrial and educational
equipment (changers, drives, LD players for educational use, etc.)
of our company, and supports Communication Mode 7 (CM 7).
CM 7 uses a method of proceeding a program by issuing each
execution command and confirming the execution status with a
request command.
First, the controller sends an execution command, and the player
returns the status of having received the command. Then, the
controller sends a request command, and the player returns the
corresponding status data. The controller repeats this operation until
it receives the status data required.
In CM 7, neither Completion of Execution Status nor error messages
are returned. Statuses returned in response to execution commands
are the End of Receive message <R> and Communication Errors
<E 00>. To confirm Completion of Execution or occurrence of
errors, use the request command “?J.” However, note that some
commands have restrictions or conditions, and that some commands
cannot be executed or may not be executed as they should be.

• Specifications of Interface
Signal level: RS-232C level
Data format
Data length : 8 bits
Stop bit: 1 bit
Parity: none
Transmission speed (baud rate):
Selectable between 9600 and 19200 bps, by exclusive command
of the player. Every time the power is turned on, the baud rate
is reset to 9600 bps.
Connection:
The computer and this unit are connected through three lines, as
shown below:
The player can receive commands any time as long as the power is
on. So, even when the RS-232C port of the computer is used,
connection of any control lines other than TxD and RxD is NOT
necessary.
However, some computers need physical CTS input for operation.
In this case, the DTR output, which always outputs positive electric
potential as long as transmission is possible, can be used. Connect
the DTR output to the CTS input of the computer as shown below:
Example of connection (connection with a DOS/V computer)
• Some operations in Search mode are prohibited for some discs. In such a case, an error is not generated when the mode is specified, but an error
is generated when execution of the SE command is attempted.
• Always use the ZS command at the beginning of a command string.
• To use the ZS command during setup (PLAYER ACTIVE STATUS = P03,) always use the ZR command before the ZS command.
• If a disc does not exist at the location specified by the ZS command, playback of the disc in the next location in numerical sequence is executed
if it is before the location of no-disc detection. If it is after the location of no-disc detection, a “No Disc Error” (E11) is generated.
• If an RJ command is issued during startup of the disc, the disc is returned to the rack, as with the ZR command.
• During GUI Menu mode (during Setup or Sub-Set-up mode,) normal commands, the NI command, or AI command cannot be accepted. If GUI
Menu mode is entered during execution of a command, only normal commands are canceled. Other commands can be accepted during GUI
Menu mode.
• Repeat mode is canceled if the SE command is executed.
• If the KO command is issued before location of no-disc detection, an error is generated, and the error code is displayed.
• The setting of Repeat mode is disabled in playback mode (Status is P1X with ?P).
• If an impossible OSD display item is specified (for example, if time display is specified for a DVD for which time data are not available) with the
DS command, an error is generated, and the error code is displayed.
• The NI and AI commands are effective only when the disc type has been detected (except for NO DISC and UNKNOWN). disc type can be
checked using the KO command.
Operation with master-slave communication
• If the disc is being returned to the rack with the ZS command, etc., while a slave player is operating, the master player will assume success of the
operation.
• The “End of Receive” Status (R) is generated by the master player. If a communication error is generated between the master and a slave player,
only the error data item “E92” is stored, and the error code “E00” will not be returned to the host computer.
• The OP, UL, and CO commands apply to only the master player even during Slave Player Operation mode. That is, opening/closing of the hood
of a slave player cannot be controlled with RS-232C commands.
• Any part of a command string after the ZR and RJ commands sent to a slave player is ignored.
• A request command to the slave player(s) takes 0.5 seconds at maximum. The ?T and ?A commands are exceptions, and return status data
immediately.
• The ?T and ?A commands during Stop mode, etc., will generate errors if issued to the master player. But this is not the case for the slave player(s),
and time data are always transmitted.
• If any connection error is detected between the master and slave players, the player returns a “E92” code once in response to any command.
Afterwards, the players will not accept any commands.
• If the host computer is connected to the slave player, the player returns a “E92” code once in response to any command. Afterwards, the players
will not accept any commands.
• Allow at least 0.5 second (1 second recommended) between commands to the slave player(s), except for the ?A, ?T, NI, AI, NO, AO, KO, and ID
commands.
• No command can be accepted during the first approximately 3 seconds after the power is turned on.
