NOTICE: Comply with all cautions and safety-related notes
located on or inside the cover case and on the chassis or plasma
module.
WARNING: Since the chassis of this receiver is connected to
one side of the AC power supply during operation, whenever the
receiver is plugged in service should not be attempted by any-
one unfamiliar with the precautions necessary when working on
this type of receiver.
1. When service is required, an isolation transformer should be
inserted between power line and the receiver before any
service is performed on a “HOT” chassis receiver.
2. When replacing a chassis in the receiver, all the protective
devices must be put back in place, such as barriers, non-
metallic knobs, insulating cover-shields, and isolation
resistors, capacitors, etc.
3. When service is required, observe the original lead dress.
4. Always use manufacturer’s replacement components. Critical
components as indicated on the circuit diagram should not be
replaced by another manufacturer’s. Furthermore, where a
short circuit has occurred, replace those components that
indicate evidence of over heating.
5. Before returning a serviced receiver to the customer, the
service technician must thoroughly test the unit to be certain
that it is completely safe to operate without danger of electrical
shock, and be sure that no protective device built into the
receiver by the manufacturer has become defective, or
inadvertently defeated during servicing.
Therefore, the following checks should be performed for the
continued protection of the customer and service technician.
Leakage Current Cold Check
With the AC plug removed from the 120V AC 60Hz source,
place a jumper across Line 1 and Line 2 of the three plug
prongs, do not connect with the third prong, which is physical
ground.
Using an insulation tester (DC500V), connect one of its leads
to the AC plug jumper and touch with the other lead each
exposed metal part (antennas, screwheads, metal overlays,
control shafts, etc.), particularly any exposed metal part
having a return path to the chassis should have a resistor
reading over 4MΩ. Any resistance value below this range
indicates an abnormality which requires corrective action. An
exposed metal part not having a return path to the chassis will
indicate an open circuit.

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 the American
National Standards Institute (ANSI) C101.0 Leakage Current
for Appliances. In the case of the PDP monitor set the AC
switch first in the ON position and then in the OFF position,
measure from across Line 1 and Line 2 of the three plug
prongs, do not connect with the third prong, which is physical
ground, 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 MIU. Reverse the
instrument power cord plug in the outlet and repeat test.

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in HITACHI television
receivers have special safety-related characteristics. These are
often not evident from visual inspection nor can the protection
afforded by them necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement
parts which have these special safety characteristics are
identified in this Service Manual.
Electrical components having such features are identified with a
mark in the schematics and parts list in this Service Manual.
The use of a substitute replacement component which does not
have the same safety characteristics as the HITACHI-
recommended replacement component, shown in the parts list in
this Service Manual, may create shock, fire, X-radiation, or other
hazards.
Product safety is continuously under review and new instructions
are issued from time to time. For the latest information, always
consult the current HITACHI Service Manual. A subscription to,
or additional copies of HITACHI Service Manuals may be
obtained at a nominal charge from HITACHI Sales Corporation.
1. Follow the general caution recommendations from “Safety
precautions” section.
42HDS69/HDT79/HDX99 - Plasma Monitor Unit
55HDS69/HDT79/HDX99 - Plasma Monitor Unit
1. Follow the general caution recommendations from “Safety
precautions” section.
2. Since the Panel module and front filter are made of glass,
sufficient care shall be taken when handling the broken
module and filter in order to avoid injury.
3. If necessary to replace Panel module, this work must be
started after the panel module and the AC/DC Power supply
becomes sufficiently cool.
4. Special care must be taken with the display area to avoid
damaging its surface.
5. The Panel Module shall not be touched with bare hands to
protect its surface from stains.
6. It is recommended to use clean soft gloves during the
replacing work of the Panel module in order to protect, not
only the display area of the panel module but also the
serviceman.
7. The Chip Tube of the panel module (located upper left of the
back of the panel module) and flexible cables connecting
Panel glasses to the drive circuitry Printed Wiring Boards
(P.W.B.) are very weak, so sufficient care must be taken to
prevent breaking or cutting any of these. If the Chip Tube
breaks the panel module will never work, replacement for a
new plasma panel module will be needed.
8. AV Digital Block, power supply and PDP driving circuit
P.W.B.’s are assembled on the rear side of the PDP module,
take special care with this fragile circuitry; particularly, Flexible
Printed Circuits bonded to surrounding edges of the glass
panel. They are not strong enough to withstand harsh outer
mechanical forces. Avoid touching the flexible printed circuits
by not only your hands, but also tools, chassis, or any other
object. Extreme bending of the connectors must be avoided
too. In case the flexible printed circuits are damaged, the
corresponding addressed portions of the screen will not be lit
and exchange of a glass panel will be required.
PDP Module Handling
When there is need to replace a broken PDP module which is the
displaying device from the Plasma monitor unit, consider the
following:
1. When carrying the PDP module, two persons should stand at
both shorter-edge sides of the glass-panel and transport it with
their palms. Avoid touching the Flexible Printed Circuits or the
chip tube on the corner of the glass-panel. Handle only by the
surface of the glass panel. In case of some PDP modules,
electrode repair is done by connecting between regular
terminal with Cu tape and Cu wire. Please do not hook and/or
damage this repair line. If it is damaged, the module will not
function unless the glass-panel is exchanged with a new
glass-panel.
2. When carrying PDP module, watch surrounding objects, such
as tables, and also do not carry it alone since it may be
dangerous and it will be damaged due to excessive stress to
the module (glass-panel).
3. Please do not stand the module with the edge of the glass-
panel on the table since this might result in damage to the
glass-panel and/or flexible printed circuits due to excessive
stress to the module (glass-panel).
WARNING
Lead in solder used in this product is listed by the California
Health and Welfare agency as a known reproductive toxicant
which may cause birth defects or other reproductive harm
(California Health and Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components
which contain lead in solder, avoid unprotected skin contact with
solder. Also, when soldering make sure you are in a well
ventilated area in order to avoid inhalation of any smoke or
fumes released.

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.
2. Do not spray chemicals on or near this instrument or any
of its assemblies.
3. Unless specified otherwise in these service data, clean
electrical contacts 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.
4. Do not defeat any plug/socket of voltage interlocks with
which instruments covered by this service data might be
equipped.
5. Do not apply AC power to this instrument and/or any of its
electrical assemblies unless all solid-state device heat-
sinks are correctly installed.
6. 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.
7. 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 field-
effect transistors and semiconductor “chip” components. The
following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor
component or semiconductor-equipped assembly, drain
off any electrostatic charge on your body by touching a
known earth ground. Alternatively, obtain and wear a
commercially available discharging wrist strap device,
which should be removed for potential shock reasons
prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface
such as aluminum foil, to prevent electrostatic charge
buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or
desolder ES devices.
4. Use only an 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 lead free solder (see page 8). Lead
solder can be used, but there is a possibility of failure due
to insufficient strength of the solder.
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 suction-
type 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 the three leads
remaining on the circuit board.
3. Bend into a “U” shape the replacement transistor leads.
4. Connect the 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 Soldering 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.

DW2U

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.

MH DIODE RESISTOR
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 1.6KΩresistor, 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.

Information for service about lead-free solder introduction
Hitachi introduced lead-free solder to conserve the "Earth Environment".
Please refer to the following before servicing.
(1) Characteristic of lead-free solder
Melting point of lead free solder is 40-50
o
C higher than solder containing lead.
(2) Solder for service
Following composition is recommended.
" Sn - 3.0Ag - 0.5Cu " , or " Sn - 0.7 Cu "
Lead solder can be used, but there is a possibility of failure due to insufficient strength of the solder.
Caution when using solder containing lead.
Please remove previous solder as much as possible from the soldering point.
When soldering, please perfectly melt the lead-free solder to mix well with the previous solder.
(3) Soldering iron for lead-free solder.
Melting point of lead-free solder is higher than solder containing lead.
Use of a soldering tool "with temperature control" and "with much thermal capacitance" is recommended.
