SAFETY PRECAUTIONS
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, nonmetallic knobs, insulating cover-shields, and isolation
resistors, capacitors, etc.
DW2U
Leakage Current Hot Check
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.
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.

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 HITACHIrecommended 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

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 glasspanel 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).
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.
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.

SERVICING PRECAUTIONS
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.
DW2U
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.
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 heatsinks 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.
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.)

DW2U
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 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.
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.)
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.
d. Closely inspect the solder area and remove any
excess or splashed solder with a small wire-bristle
brush.
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.
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.
5
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 “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 Other Connections
Use the following technique to repair defective copper
pattern at connections other than IC Pins. This technique
involves the installation of a jumper wire on the component
side of the circuit board.
DEFECTIVE
COPPER
REMOVED
Insulated 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.
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.
BARE JUMPER
WIRE
CRIMP AND
SOLDER
Install Jumper Wire and Solder
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.
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.
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.
6
DW2U
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.
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 Set Up Your New Hitachi Plasma Television
To take measures to prevent the Plasma Display from tipping over and prevent possible injury it
is important to mount the unit in a stable and flat surface.
Securing to a table-top
1. Using wood screws (two) fasten the set to the
clamping screw holes on the rear of the Plasma
Display stand as shown below.
2. Using commercially available wood screws, secure
the set firmly in position.
Wire
Wood screw

Securing to a Wall
1. Keep the Plasma television 4 inches away from the
wall except when mounted using the wall mount
bracket.
2. Secure the television to the wall as shown in fig. (a)

ANTENNA
Unless your Plasma Television is connected to a cable
TV system or to a centralized antenna system, a good
outdoor color TV antenna is recommended for best
performance. However, if you are located in an
exceptionally good signal area that is free from
interference and multiple image ghosts,
an indoor antenna may be sufficient.
LOCATION
Select an area where sunlight or bright indoor
illumination will not fall directly on the picture screen.
Also, be sure that the location selected allows a free
flow of air to and from the perforated back cover of the
set. In order to prevent an internal temperature
increase, maintain a space of 10 cm (4 inches) from the
sides/back of the monitor, and 30 cm (12 inches) from
the top of the television to the wall. To avoid cabinet
warping, cabinet color changes, and increased chance
of set failure, do not place the TV where temperatures
can become excessively hot, for example, in direct
sunlight or near a heating appliance, etc.
30 cm (12 inches)
10 cm (4 inches)
10 cm (4 inches)
NOTES:1.Do not block the ventilation holes of
the Plasma Display monitor. Blocking
the ventilation holes might cause fire
or defect.
2.In case of an abnormal symptom,
unplug the AC cord.
3.If you purchased the wall mount
bracket option, please ask for
professional installer. Do not install
by yourself.
4.If the Power Swivel feature will not be
used, the Plasma television should be
secured to the wall as shown in
fig. (a).
5.If the Power Swivel feature will be
used, the Plasma television should be
secured to the wall as shown in
fig. (b). The wires need to be long
enough to allow the television to turn
30˚ to the left and right.
Caution when moving the main unit
As this product is heavy, whenever it is moved, two
people are required to transport it safely. Whenever the
unit is moved it should be lifted forward using the top
and base on both sides of the Display Monitor for
stability. When moving the Display Monitor, lift the
handles and the bottom frame as shown below. Do not
grab the speakers or the back cover when lifting.
CONNECT POWER SWIVEL CABLE
Connect one end of cable (Arrow mark facing left) to
the swivel slot of the Plasma Rear Panel. Connect the
other end (Arrow mark facing front)to the swivel slot of
the Table Top Stand.
TURNING RADIUS
The maximum turning radius is 30˚ (left and right). Do
not place any objects on the path of the monitor when
using the power swivel feature.

HOW TO SET UP YOUR NEW HITACHI PLASMA TELEVISION
VIEWING
The best picture is seen by sitting directly in front of
the TV and about 10 to 18 feet from the screen.
During daylight hours, reflections from outside light
may appear on the screen. If so, drapes or screens
can be used to reduce the reflection or the TV can
be located in a different section of the room.
If the TV’s audio output will be connected to a Hi-Fi
system’s external speakers, the best audio
performance will be obtained by placing the

Rear Panel.
• Refer to the operating guide of your other electronic equipment for additional information on connecting
your hook-up cables.
• A single VCR can be used for VCR #1 and VCR #2, but note that a VCR cannot record its own video or line
output (INPUT: 1 in the example on page 14). Refer to your VCR operating guide for more information on
line input-output connections.
• Connect only 1 component (VCR, DVD player, camcorder, etc.) to each input jack.
• COMPONENT: Y-PBPR(Input 3, 4 & 5) connections are provided for high performance components, such as
DVD players and set-top-boxes. Use these connections in place of the standard video connection if your
device has this feature.
• Your component outputs may be labeled Y, B-Y, and R-Y. In this case, connect the components B-Y
output to the TV’s PBinput and the components R-Y output to the TV’s PRinput.
• Your component outputs may be labeled Y-CBCR. In this case, connect the components CBoutput to the
TV’s PBinput and the components CRoutput to the TV’s PRinput.
• It may be necessary to adjust TINT to obtain optimum picture quality when using the Y-PBPRinputs. (See
page 37)
• To ensure no copyright infringement, the MONITOR OUT output will be abnormal, when using the Y-PBPR, and
HDMI input jacks.
• Input 1 , 2 or 5 can accept HDMI signal.
• S-VIDEO monitor output may be used for recording only when the input is of S-VIDEO type.
• When using a HDMI input from a Set-Top-Box, it is recommended to use a 1080i or 720p input signal.
INSTALLATION RECOMMENDATION:
1. Video signals fed through a VCR may be affected by copyright protection systems and the picture will be
distorted on the television.
2. Connecting the television directly to the Audio /Video output of a Set-Top-Box will assure a more normal
picture.

A buzzing sound might be heard when the plasma display monitor is turned on in a very quiet
room. This is due to the plasma panel drive circuit when it is functioning. This arching sound
is normal and it is not a malfunction.
Some infrared rays are emitted from the plasma display monitor’s panel that might affect other
infrared controlling equipment.
High-precision technology is used to manufacture the plasma display panel; But in some
cases, there are minor defects in some parts of the screen. Points that do not light, points
with brightness different from that of the periphery, points with color different from that of the
periphery, etc. Some pixels will always be on or always off. Please note that this is not a
malfunction.
When receving still picture signals, (e.g. channel number indication or clock indication) for a
while, you can see image-like when the picture varied. This is not a defect.
The plasma display panel is lighting the phosphors by the discharge of internal radiation. In
some cases, this may cause the temperature of the panel surface to increase. Please note
that this is not a malfunction. The Plasma TV surface temperature is higher than a
Cathode-ray-tube.
The plasma panel is made from glass. Heavy shock on the front panel might damage it.
When the PDP monitor is transported horizontally, the glass panel has the possibility of being
broken or increasing the picture defects. At the time of transportation, horizontal style is
prohibited. More-over, please treat the plasma panel with great care because of a precision
apparatus. Please instruct transporters so that it should be put into the packing box at the time
of shipment.(There is a possibility that breakage of the panel or defects will increase.)
Rough transportation might cause damage to the panel and pixel failure.
The plasma monitor illuminates phosphor to display images. The phosphor has a finite
illumination life. After extended periods of illumination, the brightness of the phosphor will be
degraded to such extent that stationary images would burn-in that part of the screen as
grayed-out images.
Tips to prevent such image retention are:
- Do not display images having sharp brightness differences or hi-contrast images, such as
monochrome characters and graphic patterns, for long.
- Do not leave stationary images appearing for long, but try to refresh them at appropriate
intervals of time, or try to move them using screen saver function.
- Turn down the contrast and brightness controls.
PDP television has luminosity and low contrast compared with CRT television.
When a screen is seen at point-blank range, a random fine grain may be visible to a dark part.
If an apparatus (VCR, etc.) antenna line is arranged near the monitor, the image may shake,
or disturbance may be received.
There is some time lag betweeen the picture and the sound. You can see lip motion that is
delayed compared to the sound.
Electric discharge/luminescence characteristic of the PDP panel also changes with peripheral
temperature. Moreover, since there is also high power consumption value, a specified
temperature environment is required.
Storing the plasma television for a period of more than 2 to 3 months without use might cause
an unstable picture when the set is turned on.
Operating altitude: 800 to 1114hPa (6194ft to -2484ft). Operating temperature: 41˚F to 95˚F.
Storage Altitude: 300 to 1114hPa (31,912 to -2484ft). Storage temperature: 5˚F to 140˚F.
Frequent use of the Power ON or OFF might trigger the power protection circuit. If the TV
does not turn ON, please wait a little before turning ON again.
The 42HDT79 42HDS69 and 42HDX99 PDP TV sets
pass through adjustment procedures during the assembly
process. These adjustments must be done to assure the
best performance of the PDP set for the consumer.
Also, after servicing, these same adjustments must be
done. The adjustments are all made through the I
