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

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.

12INSTALLATION AND CONNECTIONS
Installation
Connections will vary, depending on the type of
audio and video components used with your
DVD 50. However, regardless of the complexity
of your system, the installation guidelines on
pages 14–17 should always be followed to
ensure a safe installation and reliable operation
of the product.
Important Note: To prevent possible damage
to your speakers or other components in your
home entertainment system, we strongly rec-
ommend that ALL system components, includ-
ing the DVD 50, be turned off and unplugged
from their AC power source when any connec-
tions are made or a new component is
installed.
Placement of the DVD 50
Since the laser transport mechanism and
carousel tray in the DVD 50 are precision
components designed and manufactured to
exact tolerances, they are subject to interfer-
ence from vibration. To minimize the possibility
of skipping during playback, it is recommended
that the unit be placed on a level, solid,
vibration-free surface.
When installing the DVD 50 in a cabinet or
tight space, always make certain that there is
enough room in front of the unit for the disc
tray to open fully, and that there is enough
space above the unit so that discs may easily
be inserted into the spaces in the tray.
As the disc drawer extends out about six inches
from the front of the unit when it is open, you
should also make certain that there is sufficient
clearance in front of the unit to accommodate
the disc drawer without it bumping into other
objects or getting in the way of anyone walking
in front of the unit.
In addition to the safety considerations outlined
on page 4, it is also recommended that the
DVD 50 not be placed in a location that is sub-
ject to direct sunlight or extreme heat or cold,
as these conditions may damage the discs used
in the player, or the player itself. Note that
audio amplifiers or high-power receivers, as
well as certain other electronic products, can
generate significant heat. For that reason, do
not place the DVD 50 directly on top of an
amplifier, receiver, or other heat source.
Always allow at least one inch of free space on
all sides of the DVD 50 as well as around other
electronic products to allow for proper
ventilation.
Installation Options
The diagrams on pages 14–17 describe the
three basic ways to connect the DVD 50 to your
system components.
■ Option #1: Use this setup if all audio and
video connections from the DVD 50 will go
directly to a television set or video projector
without the use of an A/V receiver or
surround processor.
■ Option #2: Use this setup if the video con-
nections will go directly to a television set or
video projector, but the audio connections
will be made to an A/V receiver or surround
processor.
■ Option #3: Use this setup if all audio and
video connections will be made through an
A/V receiver or a surround processor.
Important Notes on Installing the DVD 50
The following important notes apply to all three
installation options:
■ If your television has both standard compos-
ite video and S-Video inputs, you only need
to use one of the two connections. Where
possible, we recommend an S-Video connec-
tion, due to the higher picture quality.
■ Do not connect any of the video outputs of
the DVD 50 through a VCR. The use of
Macrovision encoding on most DVD discs
means that most discs will have a distorted
picture when connections are made through
a VCR.
■ Note that the volume level for DVD playback
may differ from the level for other input
sources to your receiver. This is normal and
does not indicate a problem with the DVD 50
or your receiver. Simply use the volume con-
trol on the receiver to set the desired level.
■ Depending on the product and brand, a
number of different descriptions are used to
label component video connections. You may
see them as Y/Pr/Pb, Y/Cr/Cb or Y/R-Y/B-Y.
For the purposes of connecting a DVD player ,
all of these labels are normally identical. The
best guide is to connect the component
video connections using the green/red/blue
color coding of the inner rings of the con-
nection jacks.
■ If your television is high-definition or “digital
ready”television, you may take advantage
of the DVD 50’s progressive scan output for
the highest video resolution possible. Make
the component video connections shown or
you may connect the component video jacks
directly to the component video or HD com-
ponent inputs on your TV or video display.
Once the connection is made, the progres-
sive scan circuitry must be activated by
changing the setup menus as shown on
page 23. Note that progressive scan capabil-
ity is not operational with standard analog
component video connections.
■ Note that all cables shown for use in the
connection diagrams are optional. Consult
your dealer or installer for information on
the best cables for your specific system
application.
■ When the progressive scan output is
activated, there is no output from either
the S-Video §or Composite Video ∞
jack.
■ When the Component Video Output ¢
is used for a standard video signal (that is
with the progressive scan output turned off),
there is no output from the S-Video §
jack, but the Composite Video Output
∞will function normally. See page 23 for
more information on video output settings.
Installation and Connections

13INSTALLATION AND CONNECTIONS
Installation and Connections
OPTION 1:
Direct Connections to a Television or
Video Projector
This is the simplest installation, as it does not
require anything other than a television set.
However, note that in this type of system you
will not be able to enjoy the benefits of Dolby
Digital or DTS discrete playback, as that
requires the digital audio processing found in
A/V receivers or surround processors. Follow as
many of these steps as needed, based on the
capabilities of your television:
Step 1: Connect the AC Power Cord ªto an
AC outlet as shown in Connection , but
do NOT turn the DVD 50 on at this point.
Step 2: Connect the left and right Analog
Audio Outputs £to the left and right audio
inputs on your television as shown in
Connection .
Step 3: Depending on the video input capabilities
of your video display, make one of the following
connections. For the highest video quality, use
component video connections, if available.
An
S-Video connection is the next best quality,
followed by a standard composite video
connection.
If the video display has component video
inputs, connect the Y/Pr/Pb Component
Outputs ¢on the DVD 50 to the matching
input jacks on the back of your television as
shown in Connection . This connection is
the same regardless of if the component con-
nection is to a digital television for progressive
scan use or to a standard analog video display.
If the video display has an S-Video input and
component video is not available, connect
the S-Video Output §on the DVD 50 to the
S-Video input on your video display as shown
in Connection .
If the only video input available on your televi-
sion is a standard video jack, connnect the
Composite Video Output ∞on the DVD 50
to a matching composite video input on your
video display, as shown in Connection .
Note that in most cases the video input jack is
recognizable by the yellow ring surrounding the
input.

OPTION 2:
Direct Connections to a Television or
Video Projector with Audio Connections
to an A/V Receiver or Surround Processor
To hear the benefits of discrete, multichannel
digital audio, you will need to use an external
Dolby Digital/DTS-capable A/V receiver or
surround processor. In this installation, you
maintain a direct video connection to your
television, but use the audio processing from
another device.
Step 1: Connect the AC Power Cord ªto an
AC outlet as shown in Connection , but
do NOT turn the DVD 50 on at this point.
Step 2: Depending on the type of A/V receiver
or surround processor you have make one of
the following audio connections:
If your A/V receiver or surround processor has
digital decoding capability for Dolby Digital and
DTS, you may make the connection by connect-
ing either an optical or coaxial cable. For optical
connections, run the cable from the Optical
Digital Output •on the DVD 50 to an opti-
cal input on the A/V receiver, as shown in
Connection . For coaxial connections, run
the cable from the Coaxial Digital Output
¶on the DVD 50 to a coaxial input on the
A/V receiver, as shown in Connection .
Either type of connection may be used and only
one is required. Remember to change the set-
tings in your receiver or processor so that the
digital input you have selected is configured for
use with the DVD video input.
If your A/V receiver or surround processor does
not have digital decoding capability, you may
still take advantage of the benefits of its analog
surround processing such as Dolby Pro Logic*.
Connect the left and right Analog Audio
Outputs £to the left and right audio inputs
on your receiver or processor, as shown in
Connection .
Step 3: Depending on the video input capabili-
ties of your video display, make one of the fol-
lowing connections. For the highest video quality
use component video connections, if available.
An S-Video connection is the next best quality,
followed by a standard composite video con-
nection.
If the video display has component video
inputs, connect the Y/Pr/Pb Component
Outputs ¢on the DVD 50 to the matching
input jacks on the back of your television as
shown in Connection . This connection is
the same regardless of whether the component
connection is to a digital television for
progressive scan use or to a standard analog
video display.
If the video display has an S-Video input and
component video is not available, connect the
S-Video Output §on the DVD 50 to the
S-Video input on your video display as shown in
Connection .
If the only video input available on your televi-
sion is a standard video jack, connnect the
Composite Video Output ∞on the DVD 50
to a matching composite video input on your
video display as shown in Connection .
Note that in most cases the video input jack is
recognizable by the yellow ring surrounding the
input.
Installation Note
■ Only one type of audio connection is
required, either digital or analog. If possible,
a digital connection is preferred as that will
enable you to listen to DVD soundtracks
with the clarity, definition and channel sepa-
ration made possible by Dolby Digital and
DTS. However, if you do not yet have a
receiver capable of digital audio processing,
you will still benefit from an analog connec-
tion so that the receiver may create a multi-
channel soundfield using Dolby Pro Logic or
other matrix decoding.

OPTION 3:
Audio and Video Connections through an
A/V Receiver or Surround Processor only
If your home entertainment system has other
audio/video input sources in addition to the
DVD 50, such as a VCR, cable set-top box or
satellite receiver, LD player, personal video
recorder or HDTV tuner, the most efficient way
to manage the various components is to make
all audio/video connections through an A/V
receiver or surround processor. This simplifies
the selection of an input source, and allows
many different components to be connected to
the same video display and speakers.
Step 1: Connect the AC Power Cord ªto an
AC outlet as shown in Connection , but
do NOT turn the DVD 50 on at this point.
Step 2: Depending on the type of A/V receiver
or surround processor you have, make one of
the following audio connections:
If your A/V receiver or surround processor has
digital decoding capability for Dolby Digital and
DTS, you may make the connection by connect-
ing either an optical or coaxial cable. For optical
connections, run the cable from the Optical
Digital Output •on the DVD 50 to an
optical input on the A/V receiver as shown in
Connection . For coaxial connections, run
the cable from the Coaxial Digital Output ¶
on the DVD 50 to a coaxial input on the A/V
receiver as shown in Connection . Either
type of connection may be used and only one is
required. Remember to change the settings in
your receiver or processor so that the digital
input you have selected is configured for use
with the DVD video input.
If your A/V receiver or surround processor does
not have digital decoding capability you may
still take advantage of the benefits of its analog
