TURER’S APPROVAL. UNAUTHORIZED MODIFICATIONS WILL NOT ONLY
VOID THE WARRANTY, BUT MAY LEAD TO YOUR BEING LIABLE FOR ANY
RESULTING PROPERTY DAMAGE OR USER INJURY.
SERVICE WORK SHOULD BE PERFORMED ONLY AFTER YOU ARE
THOROUGHLY FAMILIAR WITH ALL OF THE FOLLOWING SAFETY
CHECKS AND SERVICING GUIDELINES. TO DO OTHERWISE,
INCREASES THE RISK OF POTENTIAL HAZARDS AND INJURY TO THE
USER.
WHILE SERVICING, USE AN ISOLATION TRANSFORMER FOR PROTEC-
TION FROM A.C. LINE SHOCK.
SAFETY CHECKS
AFTER THE ORIGINAL SERVICE PROBLEM HAS BEEN CORRECTED. A
CHECK SHOULD BE MADE OF THE FOLLOWING.
SUBJECT : FIRE & SHOCK HAZARD
1. BE SURE THAT ALL COMPONENTS ARE POSITIONED IN SUCH A WAY
AS TO AVOID POSSIBILITY OF ADJACENT COMPONENT SHORTS.
THIS IS ESPECIALLY IMPORTANT ON THOSE MODULES WHICH ARE
TRANSPORTED TO AND FROM THE REPAIR SHOP.
2. NEVER RELEASE A REPAIR UNLESS ALL PROTECTIVE DEVICES
SUCH AS INSULATORS, BARRIERS, COVERS, SHIELDS, STRAIN
RELIEFS, POWER SUPPLY CORDS, AND OTHER HARDWARE HAVE
BEEN REINSTALLED PER ORIGINAL DESIGN. BE SURE THAT THE
SAFETY PURPOSE OF THE POLARIZED LINE PLUG HAS NOT BEEN
DEFEATED.
3. SOLDERING MUST BE INSPECTED TO DISCOVER POSSIBLE COLD
SOLDER JOINTS, SOLDER SPLASHES OR SHARP SOLDER POINTS.
BE CERTAIN TO REMOVE ALL LOOSE FOREIGN PARTICLES.
4. CHECK FOR PHYSICAL EVIDENCE OF DAMAGE OR DETERIORATION
TO PARTS AND COMPONENTS, FOR FRAYED LEADS, DAMAGED
INSULATION (INCLUDING A.C. CORD), AND REPLACE IF NECESSARY.
FOLLOW ORIGINAL LAYOUT, LEAD LENGTH AND DRESS.
5. NO LEAD OR COMPONENT SHOULD TOUCH A RECIVING TUBE OR
A RESISTOR RATED AT 1 WATT OR MORE. LEAD TENSION AROUND
PROTRUDING METAL SURFACES MUST BE AVOIDED.
6. ALL CRITICAL COMPONENTS SUCH AS FUSES, FLAMEPROOF
RESISTORS, CAPACITORS, ETC. MUST BE REPLACED WITH EXACT
FACTORY TYPES, DO NOT USE REPLACEMENT COMPONENTS
OTHER THAN THOSE SPECIFIED OR MAKE UNRECOMMENDED CIR-
CUIT MODIFICATIONS.
7. AFTER RE-ASSEMBLY OF THE SET ALWAYS PERFORM AN A.C.
LEAKAGE TEST ON ALL EXPOSED METALLIC PARTS OF THE CABI-
NET, (THE CHANNEL SELECTOR KNOB, ANTENNA TERMINALS. HAN-
DLE AND SCREWS) TO BE SURE THE SET IS SAFE TO OPERATE
WITHOUT DANGER OF ELECTRICAL SHOCK. DO NOT USE A LINE
ISOLATION TRANSFORMER DURING THIS TEST USE AN A.C. VOLT-
METER, HAVING 5000 OHMS PER VOLT OR MORE SENSITIVITY, IN
THE FOLLOWING MANNER; CONNECT A 1500 OHM 10 WATT RESIS-
TOR, PARALLELED BY A .15 MFD. 150.V A.C TYPE CAPACITOR
BETWEEN A KNOWN GOOD EARTH GROUND (WATER PIPE, CON-
DUIT, ETC.) AND THE EXPOSED METALLIC PARTS, ONE AT A TIME.
MEASURE THE A.C. VOLTAGE ACROSS THE COMBINATION OF 1500
OHM RESISTOR AND .15 MFD CAPACITOR. REVERSE THE A.C. PLUG
AND REPEAT A.C. VOLTAGE MEASUREMENTS FOR EACH EXPOSED
METALLIC PART. VOLTAGE MEASURED MUST NOT EXCEED 75
VOLTS R.M.S. THIS CORRESPONDS TO 0.5 MILLIAMP A.C ANY
VALUE EXCEEDING THIS LIMIT CONSTITUTES A POTENTIAL SHOCK
HAZARD AND MUST BE CORRECTED IMMEDIATELY.
SUBJECT: GRAPHIC SYMBOLS
THE LIGHTNING FLASH WITH APROWHEAD SYMBOL. WITHIN
AN EQUILATERAL TRIANGLE, IS INTENDED TO ALERT THE
SERVICE PERSONNEL TO THE PRESENCE OF UNINSULATED
“DANGEROUS VOLTAGE”THAT MAY BE OF SUFFICIENT MAG-
NITUDE TO CONSTITUTE A RISK OF ELECTRIC SHOCK.
THE EXCLAMATION POINT WITHIN AN EQUILATERAL TRIAN-
GLE IS INTENDED TO ALERT THE SERVICE PERSONNEL TO
THE PRESENCE OF IMPORTANT SAFETY INFORMATION IN
SERVICE LITERATURE.
SUBJECT : X-RADIATION
1. BE SURE PROCEDURES AND INSTRUCTIONS TO ALL SERVICE PER-
SONNEL COVER THE SUBJECT OF X-RADIATION. THE ONLY POTEN-
TIAL SOURCE OF X-RAYS IN CURRENT T.V. RECEIVERS IS THE PIC-
TURE TUBE. HOWEVER, THIS TUBE DOES NOT EMIT X-RAYS WHEN
THE HIGH VOLTAGE IS AT THE FACTORY SPECIFIED LEVEL. THE
PROPER VALUE IS GIVEN IN THE APPLICABLE SCHEMATIC. OPERA-
TION AT HIGHER VOLTAGES MAY CAUSE A FAILURE OF THE PIC-
TURE TUBE OR HIGH VOLTAGE SUPPLY AND, UNDER CERTAIN CIR-
CUMSTANCES, MAY PRODUCE RADIATION IN EXCESS OF DESIR-
ABLE LEVELS.
2. ONLY FACTORY SPECIFIED C.R.T. ANODE CONNECTORS MUST BE
USED. DEGAUSSING SHIELDS ALSO SERVE AS AN X-RAY SHIELD IN
COLOR SETS, ALWAYS RE-INSTALL THEM.
3. IT IS ESSNTIAL THAT SERVICE PERSONNEL HAVE AVAILABLE AN
ACCURATE AND RELIABLE HIGH VOLTAGE METER. THE CALIBRA-
TION OF THE METER SHOULD BE CHECKED PERIODICALLY
AGAINST A REFERENCE STANDARD, SUCH AS THE ONE AVAILABLE
AT YOUR DISTRIBUTOR.
4. WHEN THE HIGH VOLTAGE CIRCUITRY IS OPERATING PROPERLY
THERE IS NO POSSIBILITY OF AN X-RADIATION PROBLEM. EVERY
TIME A COLOR CHASSIS IS SERVICED. THE BRIGHTNESS SHOULD
BE RUN UP AND DOWN WHILE MONITORING THE HIGH VOLTAGE
WITH A METER TO BE CERTAIN THAT THE HIGH VOLTAGE DOES
NOT EXCEED THE SPECIFIED VALUE AND THAT IT IS REGULATING
CORRECTLY. WE SUGGEST THAT YOU AND YOUR SERVICE ORGA-
NIZATION REVIEW TEST PROCEDURES SO THAT VOLTAGE REGU-
LATION IS ALWAYS CHECKED AS A STANDARD SERVICING PROCE-
DURE AND THAT THE HIGH VOLTAGE READING BE RECORDED ON
EACH CUSTOMER’S INVOICE.
5. WHEN TROUBLESHOOTING AND MAKING TEST MEASUREMENTS IN
A PRODUCT WITH A PROBLEM OF EXCESSIVE HIGH VOLTAGE,
AVOID BEING UNNECESSARILY CLOSE TO THE PICTURE TUBE AND
THE HIGH VOLTAGE SUPPLY. DO NOT OPERATE THE PRODUCT
LONGER THAN IT IS NECESSARY TO LOCATE THE CAUSE OF EXCES-
SIVE VOLTAGE.
6. REFER TO HV. B+ AND SHUTDOWN ADJUSTMENT PROCEDURES
DESCRIBED IN THE APPROPRIATE SCHEMATIC AND DIAGRAMS
(WHERE USED).
SUBJECT: IMPLOSION
1. ALL DIRECT VIEWED PICTURE TUBES ARE EQUIPPED WITH AN INTE-
GRAL IMPLOSION PROTECTION SYSTEM, BUT CARE SHOULD BE
TAKEN TO AVOID DAMAGE DURING INSTALLATION, AVOID
SCRATCHING THE TUBE. IF SCRATCHED REPLACE IT.
2. USE ONLY RECOMMENDED FACTORY REPLACEMENT TUBES.
SUBJECT : TIPS ON PROPER INSTALLATION
1. NEVER INSTALL ANY PRODUCT IN A CLOSED-IN RECESS, CUBBY-
HOLE OR CLOSELY FITTING SHELF SPACE, OVER OR CLOSE TO
HEAT DUCT, OR IN THE PATH OF HEATED AIR FLOW.
2. AVOID CONDITIONS OF HIGH HUMIDITY SUCH AS: OUTDOOR PATIO
INSTALLATIONS WHERE DEW IS A FACTOR, NEAR STEAM RADIA-
TORS WHERE STEAM LEAKAGE IS A FACTOR, ETC.
3. AVOID PLACEMENT WHERE DRAPERIES MAY OBSTRUCT REAR
VENTING. THE CUSTOMER SHOULD ALSO AVOID THE USE OF DEC-
ORATIVE SCARVES OR OTHER COVERINGS WHICH MIGHT
OBSTRUCT VENTILATION.
4. WALL AND SHELF MOUNTED INSTALLATIONS USING A COMMER-
CIAL MOUNTING KIT, MUST FOLLOW THE FACTORY APPROVED
MOUNTING INSTRUCTIONS. A PRODUCT MOUNTED TO A SHELF OR
PLATFORM MUST RETAIN ITS ORIGINAL FEET (OR THE EQUIVALENT
THICKNESS IN SPACERS) TO PROVIDE ADEQUATE AIR FLOW
ACROSS THE BOTTOM. BOLTS OR SCREWS USED FOR FASTENERS
MUST NOT TOUCH ANY PARTS OR WIRING. PERFORM LEAKAGE
TEST ON CUSTOMIZED INSTALLATIONS.
5. CAUTION CUSTOMERS AGAINST THE MOUNTING OF A PRODUCT ON
SLOPING SHELF OR A TILTED POSITION, UNLESS THE PRODUCT IS
PROPERLY SECURED.
6. A PRODUCT ON A ROLL-ABOUT CART SHOULD BE STABLE ON ITS
MOUNTING TO THE CART. CAUTION THE CUSTOMER ON THE HAZ-
ARDS OF TRYING TO ROLL A CART WITH SMALL CASTERS ACROSS
THRESHOLDS OR DEEP PILE CARPETS.

SERVICING PRECAUTIONS
CAUTION : Before servicing the DVD covered by this service
data and its supplements and ADDENDUMS, read and fol-
low the SAFETY PRECAUTIONS. NOTE : if unforeseen cir-
cumstances create conflict between the following servicing
precautions and any of the safety precautions in this publi-
cations, always follow the safety precautions.
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
whitch 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 cerrectly 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 resis-
tance between each blade of the attachment plug and acces-
sible conductive parts (Note 1) should be more than 1M-
ohm.
Note 1 : Accessible Conductive Parts including Metal pan-
els, 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 compo-
nent or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known
earth ground. Alternatively, obtain and wear a commer-
cially 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 protec
tive 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 elec-
tricity sufficient to damage an ES device.)
SHIPPING PRECAUTION:
If power is removed from the unit before the “NO DISC” message, then the carousel has not reached the
home position, and movement of the laser assembly during shipping can cause the mechanism to jam.
Before the unit is shipped, the mechanism should be set to its home position performing following steps:
Power on unit. Wait until unit dis
p
la
y
s “NO DISC”. Power unit off.

11 SETUP AND CONNECTIONS
SETUP AND CONNECTIONS
•Ensure that the power switch of this unit (and of
other equipment to be connected) is set to “Off”
before commencing connection.
•Do not block the ventilation holes of any of the
equipment and arrange them so that air can
circulate freely.
•Read through the instructions before connecting
other equipment.
•Ensure that you observe the color-coding when con-
necting audio and video cables.
NOTES:
•The video output (yellow) combines the complete
video signal (composite) and sends it to the TV
(or to the A/V receiver) by one cable only. Use the
video output when your TV set is equipped with
a video input jack only.
•The S (separate) video output connector separates
the color (C) and luminance (Y) signals before trans-
mitting them to the TV set in order to achieve a
sharper picture. Use the S-Video cable when con-
necting the player to a TV equipped with an S-Video
input for improved picture clarity. Never connect
both outputs, video and S-Video, to your TV orA/V
receiver; use only one of them.
•When the audio signal is to be fed to an analog
receiver rather than to the TV, connect the audio out
jacks to any normal audio input on your amplifier/
decoder/receiver. The DVD 25/101 will “downmix”
Dolby Digital recordings to Pro Logic®*, available on
these connectors; all analog surround or stereo
signals will be fed to them directly.You can also
select the audio and video signals of all your video
devices with your A/V receiver/amplifier. For more

SETUP AND CONNECTIONS
When DVDs encoded in Dolby Digital or DTS are
played, the Dolby Digital or DTS bitstream is outputted
from the player’s optical or coaxial digital audio output.
When the player is connected to a Dolby Digital or
DTS decoder, you can enjoy theater-quality audio in
your home.An optical digital audio cable or coaxial
audio cable (both optional) is required for these con-
nections, as shown below. Only one connection is
needed, not both at the same time.
•NOTE: With multiple video sources, your audio/video
device can be used for selecting the video signal and
routing it to the TV. Connect the video or S-Video
output of the DVD 25/101 (whatever is provided with your
device) to the video or S-Video input on your device,
and the video/S-Video output of this device to your
TV. For more details, see the manual of your audio/
video amplifier/receiver.
•NOTE FOR ANALOG AUDIO: The connection from
Audio Out to the TV is optional. If you plan on using
your DVD 25/101 alone, without turning on your
complete system, this connection must be made;
then you can turn up the TV´s volume as needed.
The analog audio jacks may also be connected to
the standard analog left/right DVD or CD inputs on
your receiver to processor if you wish to use the
DVD 25/101 as the input for a multiroom system.

DIGITAL AUDIO CONNECTIONS
Digital Audio Connections
Notes when connecting the opti-
cal digital audio cable (optional)
■Remove the dust protection cap from the
optical digital audio output and connect the
cable firmly so that the configurations of both
the cable and the connector match.
■Keep the dust protection cap and always
reattach the cap when not using the connec-
tor.
Audio output from the unit’s
optical/coaxial digital audio out-
put connector
* Digital Format must be selected as “ORIGI-
NAL“ or ”PCM” in Audio Set-Up Menu
(see page 18).
For your reference:
■Dolby Digital (AC-3) is a digital sound com-
pression technique developed by the Dolby
Laboratories Licensing Corporation,
supporting 5.1-channel surround sound, as
well as stereo (2-channel) sound, this tech-
nique enables a large quantity of sound data
to be efficiently recorded on a disc.
■Linear PCM is a signal recording format used
in CDs. While CDs are recorded in
44.1 kHz/16 bit, DVDs are recorded in
48 kHz/16 bit up to 96 kHz /24 bit.
■If you have a Dolby Pro Logic Surround
decoder connected to the DVD’s analog
AUDIO OUT connectors, thanks to the
”Downmix” function of the DVD you will
obtain the full benefit of Pro Logic from the
same DVD movies that provide full 5.1-chan-
nel Dolby Digital soundtracks, as well as from
titles encoded with Dolby Surround.
■The DVD 25/101 is designed to digitally output
96kHz-PCM audio with a 96 kHz sampling
rate. The 96 kHz indicator will light in the dis-
play. However, some 96 kHz DVD's may
include copy protection codes that do not
permit digital output. For full 96 kHz fidelity
from these discs, use the analog outputs of
the DVD 25/101.
IMPORTANT: If your surround processor/D/A
converter does not support 96 kHz PCM audio,
you must use the DVD analog outputs for full
96 kHz fidelity with these discs.
Caution for the optical/coaxial
digital audio outputs:
■When connecting an amplifier (with an opti-
cal/coaxial digital input ) which does not con-
tain a Dolby Digital (AC-3) or DTS decoder, be
sure to select ”PCM” as initial setting in the
”Digital Format” menu (see also page 18).
Otherwise, any attempt to play DVD may
cause such a high level of noise that it may
be harmful to your ears and damage your
speakers.
■CD´s can be played as they would normally be
played.
Note:
■Some first generation DTS decoders which do
not support DVD-DTS interface may not work
properly with the DVD/CD player.
Dolby Digital and DTS
Both Dolby Digital and DTS are audio formats
used to record 5.1-channel audio signals onto
the digital track of film. Both of these formats
provide six separate channels: left, right, center,
left rear, right rear, and common subwoofer.
Remember, that Dolby Digital or DTS will only
play 5.1-channel sound if you’ve connected the
optical or coaxial output of the DVD 25/101 to a DTS
or Dolby Digital receiver or decoder (see page
11) and if the disc was recorded in the Dolby
Digital or DTS format.

TEST SCREEN
Test Screen
Test Screen
When you press the TEST button on the front
panel or on the remote you can activate a still
image to test all settings and the video perform-
ance of your TV. With the vertical color bars you
can test the following:
■proper color intensity setting on your TV,
■the proper color of each bar, showing if the
proper video standard is turned on: the colors
should be (left to right): black, white, yellow,
cyan (turquoise), green, magenta (purple), red,
blue, black.
■proper color transition, seen as sharp separa-
tion of the bars, S-Video will be better than
Video, RGB best of all.
■the performance of the color filter in your TV
(with ”Video” signals), bar edges should show
no vertical crawling dots. Here S-Video and
RGB formats usually give no problems.
With the grey scale and the black/white fields
below the color bars the brightness and contrast
of your screen can be adjusted optimally, see
chapter ”TV Picture Adjustment” below.
TV Picture Adjustment with
Test Screen
These adjustments may be done now, but you
can also make them after setup has been final-
ized. They can also be made at any time when
the player is in Stop or Resume mode, simply by
pressing TEST on the remote control or on the
front panel.
Brightness adjustment:
1. Turn down the color control on your TV until
the color bars are visible in black and white.
2. Adjust the contrast to the lowest level where
you still can see all bars within the grey scale
in the test picture separately and clearly.
3. Adjust the Brightness so that the bars in the
grey scale are all visible. The bar furtherst to
the left has to be as black as possible rather
than grey but the next aside must clearly be
differable. All the bars in the grey scale have to
be gradually and evenly changing from black
to whiter, going from left to right.
Contrast adjustment:
1. Adjust the contrast on your TV until you see a
bright white bar in the right low corner of the
screen and a deep dark black bar at the left.
The optimal contrast setting will depend from
your preference and the surrounding light in
the TV room.
2. If the brightness of the white bar will no more
increase while turning up the contrast or when
the borders of the white ”harman/kardon” text
letters on top will bloom (overlight) into the
black areas, what drasticly will decrease the
sharpness of the script, then the Contrast has
been turned up too much. Reduce the contrast
until these effects will disappear and the video
still looks realistic.
3. If you are watching TV with a usual surround-
ing daylight, adjust the Contrast so that a nor-
mal video picture has about the same looking
as the surroundings in your room. By that way
the eye is relazed when watching the TV pic-
ture. This contrast setting may be reduced
when the surrounding light is dimmed, usually
improving the sharpness of a video a lot there-
by.
4. The grey scale in the middle line needs to have
the same clear difference between each bar as
before the contrast adjustment. If not, go back
to the brightness adjustment and repeat step 3
and then the contrast adjustments, making
only minor adjustments each time for optimisa-
tion.
Color adjustment.
1. When the Brightness and the Contrast are set
optimally, turn up the color control to the level
of your perference. Adjust to the level where
the colors look strong but still natural, not
overdone. If the color level is too high, depend-
ing from the TV used some of the bars will
seem wider or the color intensity will not
increase while the control is turned up. Then
the color control must be reduced again. At the
end you should test the color intensity also
with a video, e.g. pictures of natural faces,
flowers, fruit and vegetables and other well
known natural articles of our life most usefull
for an optimal setting of the color intensity.
2. If your TV has a Tint option (with most
European TVs this is available or effective only
with NTSC signals, not with PAL), use the large
white bar below the Greyscale to tweak the
warmth of the picture. Every viewer has a dif-
ference in preference as how the glow of the
picture should be. Some prefer a little colder
picture, some a warmer glow. The Tint function
on your TV and the white bar can be used to
control this. Adjust the Tint to the level where
you feel the white color has the tone you
prefer.
