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: Turn 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-ofplate, 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.

DP27/27D
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 tube’s 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 “antistatic” 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

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 antistatic, 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.

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 “liftoff,” 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.
Component Removal
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 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
NOTES: 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.

FEATURE INFORMATION
As the digital era dawns, Hitachi has models that provide the best possible images today...and tomorrow. Our HDTV Ready
model incorporates new Flex Converter technology to display a high quality 1080i (high definition scanning) or 540P
(progressive scanning) image; this same circuitry enables it to accept a full 1080i HDTV signal from a digital set-top box now
or in the future.
FLEX CONVERTER TECHNOLOGY
With current analog broadcasts, there is just one level of picture quality. In the new age of digital TV, there will be several levels.
The highest, called HDTV, can be as high as 1080i.The next level, called HDTV, can be 720P. The standard level, SDTV, can
be 480P or 480i. Hitachi has developed the Flex Converter, advanced circuitry that allows your UltraVision TWX and SWX
series television to produce true 1080i HDTV resolution with an HDTV set-top box. It converts analog 480i signals to the
higher-quality 540P signals with no scan lines or flicker. The TWX and SWX needs a set-top box to receive any Digital Signal.
COMPONENT VIDEO
Component Video inputs accept separate blue, red & B/W signals from a high resolution digital source as DVD or digital settop box to provide a higher resolution picture.
3DYC (DIGITAL 3DYC COMB FILTER)
The Digital 3DYC Comb Filter analyzes three lines of information from a single video frame as well as lines from adjacent
frames. This technology eliminates the flickering that a detailed pattern or scene would normally cause, for the cleanest,
neatest picture possible.
PROGRESSIVE SCANNING
A standard TV uses Interlaced Scanning where each frame of video is broken into two fields, each providing alternating scan
lines. This can leave noticeable scan lines and cause flickering. With Progressive Scanning, complete frames are displayed for
a smoother picture with no scan lines and no flicker. This allows you to get the optimal picture quality from today’s high
resolution digital sources such as DVD or a digital set-top box.

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.
V. POSITION
This function allows you to select when aspect style is either 4:3 EXPANDED/ZOOM1/ZOOM2. Vertical position can be changed with
this mode. Adjustable range is -10 (video center is toward bottom of screen) to +10 (video center is toward top of screen).

*IMPORTANT
For many of the above adjustments, it is necessary to have an HDTV (1080i or 720P) signal generator, SDTV (480P)
signal generator, as well as the usual NTSC (480i) signal generator.
Hitachi recognizes that few companies offer HDTV or SDTV signal generators and that the cost of these
generators is sometimes prohibitive. For this reason, we suggest the use of a set-top-box for HDTV and SDTV
adjustments. Usually, there is a switch on the set-top-box which enables it to output HDTV (1080i or 720P) or
SDTV (480P) signals even with no input. In this case, the sync is automatically detected by the TV (at the Y-P
BPR
Inputs on the rear panel).

1. (3x3) Press “INFO” 5 times (only works
when DCU is in uncorrected state)
2. (7x5) Press “0” 5 times
3. (13x9) Press “ANT” 5 times
For touch-up, only the (13x9) mode is necessary.
This will adjust every cross-hatch intersection point
on the screen.
For complete adjustment, start with (3x3) mode. This
will adjust center point and eight edge points only,
but will greatly reduce adjustment time. Then use
(7x5) mode, and finally (13x9) mode to finish
convergence.
If “S” distortion appears between cross-hatch
lines repeat (7x5) mode to change calculation
process while adjusting to remove distortion,
then return to (13x9) mode to finish touch-up
convergence.
Adjustment procedure
(1) Receive any NTSC signal.
(2) Start adjustment at the center of the screen.
(3) Continue adjustment at next closest position.
(4) Adjust center area first, ending with edge sections.
(5) Press INFO button to perform calculation operation.
This process will take about 1 second and no picture
will be seen at this time.
(6) After interpolation, check convergence again and
repeat (1)-(5) if necessary.
(7) When convergence is acceptable, press PIP MODE
to write data to ROM memory. ROM WRITE? is
displayed to alarm system that ROM will be
overwritten with new data. Press the PIP MODE
button again to write displayed data to ROM.
(8) DATA WRITE TO ROM will take approximately 4
seconds and no picture will be displayed.
(9) Green dots will be displayed when operation is
completed.
(10) Press MUTE to return to convergence pattern, then
confirm again convergence is acceptable.
(11) Press PIP MODE (ROM WRITE) mode, then press
PIP CH to initialize sensor data positions.
Notes: (1) Display only green for easier adjustment and
match to jig screen. Press “MENU”, THEN
PRESS “INFO”.
(2) Perform interpolation and data write to ROM
after green adjustment. Once green has been
confirmed to match jig screen, the jig screen can
be removed. Do not readjust the green color
after jig screen has been removed. This is now
your reference color.
(3) Display green and red only and match red to
green.
(4) Display all colors and match blue to green and
red. Touch-up red color if necessary.
(5) Existing DATA in ROM can be read by pressing
the SWAP button 2 times. This data can be used
after replacing a component (CRT, DY, etc.)
Where complete convergence adjustment is not
necessary, be careful not to overwrite this data.
DO NOT write cleared RAM data into ROM or a
complete convergence adjustment will be
necessary. Remember to try MAGIC FOCUS
before starting convergence adjustment to
minimize adjustment time.
(6) To confirm and fine tune the convergence at the
edge of the screen, press the PIP CH button on
the remote control while in the digital
convergence adjustment mode (DCAM) for
additional lines at the edge of the screen. Fine
tune the edge convergence as necessary. To
exit, press PIP CH again.
