IMPORTANT SAFETY INSTRUCTION

1. Before returning an instrument to the customer, always
make a safety check of the entire instrument, including
but not limited to the following items.

a. Be sure that no built-in protective devices are

defective and/or have been deleted during servicing.
(1) Protective shields are provided on this chassis to
protect both the technician and the customer.
Correctly replace all missing protective shields,
including any removed for servicing convenience. (2)
When reinstalling the chassis and/or other assembly
in the cabinet, be sure to put back in place all
protective devices, including but not limited to,
nonmetallic control knobs, insulating fishpaper,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not operate

this instrument or permit it to be operated without
all protective devices correctly installed and
functioning. Servicers who defeat safety features
or fail to perform safety checks may be liable for
any resulting damage.

b. Be sure that there are no cabinet openings through

which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to (1) spacing
between the picture tube and cabinet mask, (2)
excessively wide cabinet ventilation slots, and (3) an
improperly fitted and/or incorrectly secured cabinet
back cover.

c. Antenna Cold Check – With the instrument AC plug

removed from any AC source, connect an electrical
jumper across the two AC plug prongs. Place the
instrument AC switch in the on position. Connect one
lead of an ohmmeter to the AC plug prongs tied
together and touch the other ohmmeter lead in turn to
each tuner antenna input, exposed terminal screw
and, if applicable, to the coaxial connector. If the
measured resistance is less than 1.0 megohms or
greater than 5.2 megohms, an abnormality exists that
must be corrected before the instrument is returned to
the customer. Repeat this test with the instrument AC
switch in the off position.

d. Leakage Current Hot Check – With the instrument

completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation
transformer during this test.) Use a leakage current
tester or a metering system that complies with
American National Standards Institute (ANSI) C101.0
Leakage Current for Appliances and Underwriters
Laboratories (UL) 1410, (50.7). With the instrument
AC switch first in the on position and then in the off
position, measure from a known earth ground (metal
waterpipe, conduit, etc.) to all exposed metal parts of
the instrument (antennas, handle bracket, metal
cabinet, screw heads, metallic overlays, control
shafts, etc.), especially any exposed metal parts that
offer an electrical return path to the chassis. Any
current measured must not exceed 0.5 milliamps.
Reverse the instrument power cord plug in the outlet
and repeat test.

ANY MEASUREMENTS NOT WITHIN THE LIMITS
SPECIFIED HEREIN INDICATE A POTENTIAL
SHOCK HAZARD THAT MUST BE ELIMINATED
BEFORE RETURNING THE INSTRUMENT TO THE
CUSTOMER OR BEFORE CONNECTING THE
ANTENNA OR ACCESSORIES.

e. High Voltage – This receiver is provided with a hold

down circuit for clearly indicating that voltage has
increased in excess of a predetermined value.
Comply will all notes described in this Service Manual
regarding this hold down circuit when servicing, so
that this hold down circuit may correctly be operated.

f. Service Warning – With maximum contrast, operating

high voltage in this receiver is lower than 30.5 kV. In
case any component having influence on high voltage
is replaced, confirm that the high voltage with
maximum contrast is lower than 30.5 kV.
To measure H.V. use a high impedance H.V. meter.
Connect (-) to chassis earth and (+) to the CRT anode
button. (See the following connection diagram.)

Note: Tu rn power switch off without fail before the

connection to the anode button is made.

g. X-radiation – TUBE: The primary source of X-

radiation in this receiver is the picture tube. The tube
utilized for the above mentioned function in this
chassis is specially constructed to limit X-radiation
emissions.
For continued X-radiation protection, the replacement
tube must be the same type as the original, Hitachi
approved type.
When troubleshooting and making test measure­ments in a receiver with a problem of excessive high
voltage, avoid being unnecessarily close to the picture
tube and the high voltage component.
Do not operate the chassis longer than is necessary
to locate the cause of excessive voltage.

h. X-radiation Shield –

1. This receiver is provided with X-ray shield plates
for protection against X-radiation. Do not remove
X-ray shield plates A, B, or C shown in Fig. 1
unnecessarily, when troubleshooting and/or
making test measurements.

2. To prevent X-radiation, after replacement of
picture tube and lens, confirm these components
to be fixed correctly to bracket and cabinet, and
not to be taken off easily.

2. Read and comply with all caution and safety-related
notes on or inside the receiver cabinet, on the receiver
chassis, or on the picture tube.

3. Design Alteration Warning – Do not alter or add to
the mechanical or electrical design of this TV receiver.
Design alterations and additions including but not
limited to circuit modifications and the addition of
items such as auxiliary audio and/or video output
connectors, might alter the safety characteristics of
this receiver and create a hazard to the user. Any
design alterations or additions may void the
manufacturer’s warranty and may make you, the
servicer, responsible for personal injury or property
damage resulting therefrom.

4. Picture Tube Implosion Protection Warning – The
picture tube in this receiver employs integral implosion
protection. For continued implosion protection,
replace the picture tube only with one of the same
type number. Do not remove, install, or otherwise
handle the picture tube in any manner without first
putting on shatterproof goggles equipped with side
shields. People not so equipped must be kept safely
away while picture tubes are handled. Keep the
picture tube away from your body. Do not handle the
picture tube by its neck.

5. Hot Chassis Warning – a. Some TV receiver chassis
are electrically connected directly to one conductor of
the AC power cord and may be safely serviced without
an isolation transformer only if the AC power plug is
inserted so that the chassis is connected to the
ground side of the AC power source. Confirm that the
AC power plug is inserted correctly with an AC
voltmeter by measuring between the chassis and a
known earth ground. If a voltage reading in excess of

1.0V is obtained, remove and reinsert the AC power
plug in the opposite polarity and again measure the
voltage potential between the chassis and a known
earth ground. b. Some TV receiver chassis normally
have 85V AC (RMS) between chassis and earth
ground regardless of the AC plug polarity. These
chassis can be safely serviced only with an isolation
transformer inserted in the power line between the
receiver and the AC power source, for both personnel
and test equipment protection. c. Some TV receiver
chassis have a secondary ground system in addition
to the main chassis ground. This secondary ground
system is not isolated from the AC power line.The two
ground systems are electrically separated by
insulating material that must not be defeated or
altered.

6. Observe original lead dress. Take extra care to assure
correct lead dress in the following areas: a. near sharp
edges, b. near thermally hot parts – be sure that leads
and components do not touch thermally hot parts, c.
the AC supply, d. high voltage and e. antenna wiring.
Always inspect in all areas for pinched, out-of-plate, or
frayed wiring. Do not change spacing between
components and the printed circuit board. Check AC
power cord for damage.

7. Components, parts, and/or wiring that appear to have
overheated or are otherwise damaged should be
replaced with components, parts, or wiring that meet
original specifications. Additionally, determine the
cause of overheating and/or damage and, if
necessary, take corrective action to remove any
potential safety hazard.

8. PRODUCT SAFETY NOTICE – Many TV electrical
and mechanical parts have special safety-related
characteristics some of which are often not evident
from visual inspection, nor can the protection they
give necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc.
Parts that have special safety characteristics are
identified in Hitachi service data by shading on
schematics and by a in the parts list. Use of
substitute replacement that does not have the same
safety characteristics as the recommended replace­ment part in Hitachi service data parts list might
create shock, fire, and/or other hazards. Product
safety is under review continuously and new
instructions are issued whenever appropriate. For the
latest information, always consult the appropriate
current Hitachi service literature. A subscription to, or
additional copies of service literature may be obtained
at a nominal charge from Hitachi.

DP26

CAUTION: Before servicing instruments covered by this
service data and its supplements and addenda, read and
follow the “Important Safety Instructions” on page 3 of this
publication.
NOTE: If unforeseen circumstances create conflict between
the following servicing precautions and any of the safety
precautions on page 3 of this publication, always follow the
safety precautions. Remember: Safety First.

General Servicing Guidelines

1. Always unplug the instrument AC power cord from the AC
power source before:
a. Removing or reinstalling any component, circuit

board, module, or any other instrument assembly.

b. Disconnecting or reconnecting any instrument

electrical plug or other electrical connection.

c. Connecting a test substitute in parallel with an

electrolytic capacitor in the instrument.

CAUTION: A wrong part substitution or incorrect

polarity installation of electrolytic
capacitors may result in an explosion
hazard.

d. Discharging the picture tube anode.

2. Test high voltage only by measuring it with an appropriate
high voltage meter or other voltage measuring device
(DVM, FETVOM, etc.) equipped with a suitable high
voltage probe. Do not test high voltage by “drawing an
arc.” The H.V. Distribution Box has an internal 400MΩ
resistor (bleeder resistor) connected from the high
voltage to ground. After power is removed from the
instrument the high voltage will discharge through the
high voltage bleeder resistor. If the tubes have high
voltage after power is removed, then the bleeder resistor
is defective or the bleeder ground is disconnected.

3. Discharge the picture tubes anode at any of the R, G, or
B outputs on the H.V. Distribution Box only by (a) first
connecting one end of an insulated clip lead to the
degaussing or kine aquadag grounding system shield at
the point where the picture tube socket ground lead is
connected, and then (b) touch the other end of the
insulated clip lead to the picture tube high voltage
distribution box R, G, or B output, using an insulated
handle to avoid personal contact with high voltage.

4. Do not spray chemicals on or near this instrument or any
of its assemblies.

5. Unless specified otherwise in these service data, clean
electrical contracts by applying the following mixture to
the contacts with a pipe cleaner, cotton-tipped stick or
comparable nonabrasive applicator: 10% (by volume)
Acetone and 90% (by volume) isopropyl alcohol (90%­99% strength).
CAUTION: This is a flammable mixture. Unless

specified otherwise in these service data,
lubrication of contacts is not required.

6. Do not defeat any plug/socket B+ voltage interlocks with
which instruments covered by this service data might be
equipped.

7. Do not apply AC power to this instrument and/or any of its
electrical assemblies unless all solid-state device heat­sinks are correctly installed.

8. Always connect the test instrument ground lead to the
appropriate instrument chassis ground before connecting
the test instrument positive lead. Always remove the test
instrument ground lead last.

9. Use with this instrument only the test fixtures specified in
this service data.
CAUTION: Do not connect the test fixture ground strap

to any heatsink in this instrument.

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 field­effect 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
desolder ES devices.

4. Use only can anti-static type solder removal device.Some
solder removal devices not classified as “anti-static” can
generate electrical charges sufficient to damage ES
device.

5. Do not use freon-propelled chemicals. These can
generate electrical charges 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. (Otherwise 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.)

General Soldering Guidelines

1. Use a grounded-tip, low-wattage soldering iron and
appropriate tip size and shape that will maintain tip
temperature within the range 500°F to 600°F.

2. Use an appropriate gauge of resin-core solder composed
of 60 parts tin/40 parts lead.

3. Keep the soldering iron tip clean and well-tinned.

4. Thoroughly clean the surfaces to be soldered. Use a
small wire-bristle (0.5 inch or 1.25 cm) brush with a metal
handle. Do not use freon-propelled spray-on cleaners.

5. Use the following desoldering technique.
a. Allow the soldering iron tip to reach normal

temperature (500°F to 600°F).

b. Heat the component lead until the solder melts. Quickly

draw away the melted solder with an anti-static,
suction-type solder removal device or with solder
braid.
CAUTION: Work quickly to avoid overheating the

circuit board printed foil.

6. Use the following soldering technique.
a. Allow the soldering iron tip to reach normal

temperature (500°F to 600°F).

b. First, hold the soldering iron tip and solder strand

against the component lead until the solder melts.

c. Quickly move the soldering iron tip to the junction of

the component lead and the printed circuit foil, and
hold it there only until the solder flows onto and
around both the component lead and the foil.
CAUTION: Work quickly to avoid overheating the

circuit board printed foil or components.

d. Closely inspect the solder area and remove any excess

or splashed solder with a small wire-bristle brush.

Removal

1. Desolder and straighten each IC lead in one operation by
gently prying up on the lead with the soldering iron tip as
the solder melts.

2. Draw away the melted solder with an anti-static suction­type solder removal device (or with solder braid) before
removing the IC.

Replacement

1. Carefully insert the replacement IC in the circuit board.

2. Carefully bend each IC lead against the circuit foil pad
and solder it.

3. Clean the soldered areas with a small wire-bristle brush.
(It is not necessary to reapply acrylic coating to areas.)

“Small-signal” Discrete Transistor Removal/Replacement

1. Remove the defective transistor by clipping its leads as
close as possible to the component body.

2. Bend into a “U” shape the end of each of three leads
remaining on the circuit board.

3. Bend into a “U” shape the replacement transistor leads.

4. Connect to replacement transistor leads to the
corresponding leads extending from the circuit board and
crimp the “U” with long nose pliers to insure metal to
metal contact, then solder each connection.

Power Output Transistor Devices Removal/Replacements

1. Heat and remove all solder from around the transistor
leads.

2. Remove the heatsink mounting screw (if so equipped).

3. Carefully remove the transistor from the circuit board.

4. Insert new transistor in circuit board.

5. Solder each transistor lead, and clip off excess lead.

6. Replace heatsink.

Diode Removal/Replacement

1. Remove defective diode by clipping its leads as close as
possible to diode body.

2. Bend the two remaining leads perpendicularly to the
circuit board.

3. Observing diode polarity, wrap each lead of the new
diode around the corresponding lead on the circuit board.

4. Securely crimp each connection and solder it.

5. Inspect (on the circuit board copper side) the solder joints
of the two “original leads”. If they are not shiny, reheat
them and, if necessary, apply additional solder.

Use Solding Iron to Pry Leads

IC Removal/Replacement

Some Hitachi unitized chassis circuit boards have slotted
holes (oblong) through which the IC leads are inserted and
then bent flat against the circuit foil. When holes are the
slotted type, the following technique should be used to
remove and replace the IC.When working with boards using
the familiar round hole, use the standard technique as
outlined in paragraphs 5 and 6 above.

SERVICING PRECAUTIONS

Fuses and Conventional Resistor Removal/Replacement

1. Clip each fuse or resistor lead at top of circuit board
hollow stake.

2. Securely crimp leads of replacement component around
stake 1/8 inch from top.

3. Solder the connections.

CAUTION: Maintain original spacing between the

replaced component and adjacent
components and the circuit board, to
prevent excessive component
temperatures.

Circuit Board Foil Repair

Excessive heat applied to the copper foil of any printed
circuit board will weaken the adhesive that bonds the foil to
the circuit board, causing the foil to separate from, or “lift-off,”
the board. The following guidelines and procedures should
be followed whenever this condition is encountered.

In Critical Copper Pattern Areas
High component/copper pattern density and/or special
voltage/current characteristics make the spacing and
integrity of copper pattern in some circuit board areas more
critical than in others. The circuit foil in these areas is
designated as Critical Copper Pattern. Because Critical
Copper Pattern requires special soldering techniques to
ensure the maintenance of reliability and safety standards,
contact your Hitachi personnel.

At IC Connections
To repair defective copper pattern at IC connections, use the
following procedure to install a jumper wire on the copper
pattern side of the circuit board. (Use this technique only on
IC connections.)

1. Carefully remove the damaged copper pattern with a
sharp knife. (Remove only as much copper as absolutely
necessary.)

2. Carefully scratch away the solder resist and acrylic
coating (if used) from the end of the remaining copper
pattern.

3. Bend a small “U” in one end of a small-gauge jumper wire
and carefully crimp it around the IC pin. Solder the IC
connection.

4. Route the jumper wire along the path of the cut-away
copper pattern and let it overlap the previously scraped
end of the good copper pattern. Solder the overlapped
area, and clip off any excess jumper wire.

1. Remove the defective copper pattern with a sharp knife.
Remove at least 1/4 inch of copper, to ensure hazardous
condition will not exist if the jumper wire opens.

2. Trace along the copper pattern from both wire sides of the
pattern break and locate the nearest component directly
connected to the affected copper pattern.

3. Connect insulated 20-gauge jumper wire from the
nearest component on one side of the pattern break to
the lead of the nearest component on the other side.
Carefully crimp and solder the connections.

CAUTION: Be sure the insulated jumper wire is

dressed so that it does not touch
components or sharp edges.

Frequency Synthesis (FS) Tuning Systems

1. Always unplug the instrument AC power cord before
disconnecting or reconnecting FS tuning system cables
and before removing or inserting FS tuning system
modules.

2. The FS tuner must never be disconnected from the FS
tuning control module while power is applied to the
instrument.

3. When troubleshooting intermittent problems that might be
caused by defective cable connection(s) to the FS tuning
system, remove the instrument AC power as soon as the
defective connector is found and finish confirming the bad
connection with a continuity test. This procedure will
reduce the probability of electrical overstress of the FS
system semi-conductor components.

Leadless Chip Components
(surface mount)

Chip components must be replaced with identical
chips due to critical foil track spacing. There are no
holes in the board to mount standard transistors or
diodes. Some chip capacitor or resistor board solder
pads may have holes through the board, however the
hole diameter limits standard resistor replacement to
1/8 watt. Standard capacitors may also be limited for
the same reason. It is recommended that identical
chip components be used. .
Chip resistors have a three digit numerical resistance
code -1st and 2nd significant digits and a multiplier.
Example: 162 = 1600 or 1.6KΩ resistor, 0 = 0Ω
(jumper).
Chip capacitors generally do not have the value
indicated on the capacitor.The color of the component
indicates the general range of the capacitance.
Chip transistors are identified by a two letter code.The
first letter indicates the type and the second letter, the
grade of transistor.
Chip diodes have a two letter identification code as per
the code chart and are a dual diode pack with either
common anode or common cathode. Check the parts
list for correct diode number.

1. Use solder wick to remove solder from component
end caps or terminals.

2. Without pulling up, carefully twist the component
with tweezers to break the adhesive.

3. Do not reuse removed leadless or chip
components since they are subject to stress
fracture during removal .

Chip Component Installation

1. Put a small amount of solder on the board
soldering pads.

2. Hold the chip component against the soldering
pads with tweezers or with a miniature alligator
clip and apply heat to the pad area with a 30 watt
iron until solder flows. Do not apply heat for more
than 3 seconds

How to Replace Flat-lC
—Required Tools—

• Soldering iron • iron wire or small awl

•De-solder braids • Magnifier

1. Remove the solder from all of the pins of a Flat-lC
by using a de-solder braid.

2. Put the iron wire under the pins of the Flat-lC and
pull it in the direction indicated while heating the
pins using a soldering iron. A small awl can be
used instead of the iron wire.

3. Remove the solder from all of the pads of the
Fiat-lC by using
a de-solder braid.

4. Position the new Flat-lC in place (apply the pins of
the Flat-lC to the soldering pads where the pins
need to be soldered). Properly
determine the positions of the
soldering pads and pins by
correctly aligning the polarity
symbol.

6. Check with a magnifier for solder bridge between

the pins or for dry joint between pins and soldering
pads. To remove a solder bridge, use a de-solder braid
as shown in the figure below.

NOTE: These components are affixed with glue. Be careful not to break or damage any foil under the
component or at the pins of the ICs when removing. Usually applying heat to the component for a short
time while twisting with tweezers will break the component loose.

Auto Digital Convergence Adjustment

Please turn ON your television for at least 20 minutes before using this feature.

The Magic Focus button on the control panel will not work when Adjustment Mode is set to Manual (see page 17).

Your HITACHI Projection TV has three color projection tubes: one for red, one for green, one for blue. When mixed together in the proper
proportion, the output of these three color tubes can produce any color. To produce these colors, however, the beams must be precisely
aligned over each other so that the colors can be mixed. The process of aligning these picture beams is called “convergence”.

Over a period of time, the picture tubes can drift out of alignment due to normal bumps and vibrations or moving the TV. If you move
your TV, or if, after a time, you notice color rings or halos around objects in the picture, you may want to converge (align) the colors.

Properly converged, the lines appear white, which is actually a combination of the outputs of the three color tubes. The output of the
green tube is stationary. The outputs of the red and blue tubes can be adjusted. When properly aligned, the outputs of all three tubes
should be directly over each other to produce the white lines.

To simplify convergence, HITACHI incorporates a function called MAGIC FOCUS located on the front control panel, which allows the TV
to self-adjust. Press this MAGIC FOCUS button and the convergence self adjustment will start and this process will take approximately
20 seconds. If this button is pressed during this process, no change in picture quality will occur. After this 20 second self-adjust period,
picture quality will be optimum. (Do not move the TV during self-adjust.)

You may also select Magic Focus from the VIDEO menu.

Magic Focus

NOTE: Only a momentary press of the MAGIC FOCUS button is necessary to start AUTO DIGITAL CONVERGENCE. At any

time during this convergence correction process, you may press the MAGIC FOCUS button to exit the MAGIC FOCUS
mode. However, the convergence correction process needs to be completed to SAVE the new corrected convergence
data.

Using the Remote Control, select VIDEO-MAGIC FOCUS-MANUAL ADJUSTMENT MODE-START to access convergence crosshatch
pattern. The adjustment point is indicated by the Adjustment Point Cursor.

To Move Adjustment Point

To move the adjustment point cursor using the THUMBSTICK, the Adjustment Cursor must be WHITE. Another way to move the
Adjustment Point Cursor is to press the following buttons: [2] up, [4] left, [5] down, [6] right. If you use the number buttons while the
adjustment point is WHITE, it will change to RED.

To Change the Color of Adjustment Point

Press the SELECT button repeatedly (WHITE-RED-BLUE-WHITE...). Green color is fixed and cannot be adjusted.

To Adjust the Convergence

Move the Adjustment Cursor to the point to be adjusted. Use the THUMB STICK to match the RED and BLUE colors to GREEN
(reference color). Properly aligned, all three colors should appear white.

If convergence is acceptable after Manual Convergence adjustment, press EXIT button to access menu mode.

Press the [1] button on the remote control to SAVE adjusted data and return to main picture.
Press the [2] button on the remote control to CANCEL adjusted data and return to main picture.
Press the [3] button on the remote control to recall the factory pre-set convergence data.
Press the [4] button on the remote control to return to the manual convergence adjustment mode (crosshatch pattern).

CONNECTING EXTERNAL VIDEO SOURCES

CONNECTING A COMPONENT SOURCE WITH DIGITAL INTERFACE CAPABILITY TO IEEE1394 TERMINALS

1. Connect the IEEE1394 cable from the output of the component with IEEE1394 capability, such as a Set-Top-Box or Digital VCR,
to the IEEE1394 input terminals shown on the TV set below. IEEE 1394 allows the television and the external device to
communicate with one another. When using IEEE1394 connections, you enable video and audio digital data exchange between
a compatible device. This connection also enables you to control basic equipment functions (such as VCR play, rewind, fast for
ward, stop, etc.) from your TV On-Screen Display. You must be tuned to ANT C to use this function.

2. Press the MENU button on the Remote Control and select SETUP.

3. Select Set-up - Set The Inputs - IEEE1394 (or press the A/V Net button twice (2x) when in ANT C mode.

4. Select IEEE1394 to verify that the component is properly connected.

NOTES: 1. To quickly enter IEEE1394 menu, press the A/V NET button on the remote control twice when in ANT C mode.

2. The external device that is connected to the IEEE 1394 terminals will not need the A/V Network feature.

3. This TV’s IEEE1394 connection is not compatible with a DV camcorder (Digital Video camcorder) and a PC.

4. With IEEE1394 connection, video and audio will be received by the TV. It will enable you to control the D-VHS from
the TV IEEE1394 menu.

5. The IEEE1394 interface contains the copy protection standard called 5C or Digital Transmission Content Protection
(DTCP).

6. This TV does not support full network control of several IEEE1394 devices simultaneously (the IEEE1394 will
disconnect from 1st device when making connection to 2nd device).

ASPECT STYLE

ASPECT STYLE

Press the ASPECT button on the Remote Control to quickly change the ASPECT ratio.

Depending on the input signal, the picture format ratio allows you to adjust the images through the following options.

4:3 STANDARD Use this aspect mode to display conventional (4:3) images. Side panels (gray areas) are placed to the

left and right of the image to preserve the original aspect ratio of the source. Note: Use this mode for
only 15% of your total viewing time to prevent uneven aging of the phosphors. Phosphors in the lighted
area of the picture will age more rapidly than the gray areas.

4:3 EXPANDED Use this aspect mode to display conventional (4:3) sources by expanding the outer edges of the image

to fill the 16:9 screen. The center of the image remains unaltered.

4:3 Zoom1/Zoom2 Use these aspect modes to zoom in on conventional (4:3) sources.

16:9 STANDARD Use this aspect mode to display 16:9 sources like HDTV and DVD’s preserving the original 16:9 aspect

ratio.

16:9 Zoom Use this aspect to Zoom-in once while in 16:9 aspect.
