SAFETY PRECAUTIONS
LC48/B-LC47/B/K
NOTICE: Comply with all cautions and safety-related notes
located on or inside the cabinet and on the chassis or optic unit.
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 anyone unfamiliar with the precautions necessary when working on
this type of receiver.
The following precautions should be observed:
1. Do not install, remove, or handle the optic unit in any manner
unless shatterproof goggles are worn. People not so equipped
should be kept away from the optic unit while handling.
2. 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.
3. When replacing a chassis in the receiver, all the protective
devices must be put back in place, such as barriers, nonmetallic knobs, adjustment and compartment cover-shields, isolation
resistors, capacitors, etc.
4. When service is required, observe the original lead dress.
5. Always use the 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 overheating.
6. 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.
Leakage Current Hot Check
Plug the AC line cord directly into a 120V AC 60Hz outlet (do not use
an isolated transformer for this check).Turn the AC power ON. Using
a Leakage Current Tester (Simpson’s Model 228 or equivalent),
measure for current from all exposed metal parts of the cabinet
(antennas, screwheads, overlays, control shafts, etc.) particularly
any exposed metal
part having a return path to the chassis or to a
known earth ground (water pipe, conduit, etc.). Any current measured must not exceed 0.5 MIU.
(READING
SHOULD NOT
BE ABOVE
0.5 MIU)
AC LEAKAGE TEST
ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED
ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD
AND MUST BE CORRECTED BEFORE RETURNING THE
RECEIVER TO THE CUSTOMER.
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 the two plug prongs. Using an insulation tester
(DC500V), connect one lead to the jumpered AC plug and touch
the other lead to 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 minimum
resistor reading of 2.4M
q. Any resistance value below or above this range indicates
5.2M
q and a maximum resistor reading of
an abnormality which requires corrective action. An exposed metal
part having a return path to the chassis will indicate an open circuit.

SERVICING PRECAUTIONS
CAUTION: Before servicing instruments covered by this service
data and its supplements and addenda, read and follow the SAFETY PRECAUTIONS on page 2 of this publication.
NOTE: If unforseen circumstances create conflict between the following SERVICING PRECAUTIONS and any of the SAFETY PRECAUTIONS on page 2 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.
LC48/B-LC47/B/K
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 build-up or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or desolder ES
devices.
b. Disconnecting or reconnecting any instrument electrical
plug or other electrical connection.
c. Connecting a test substitute in parallel with an electrolyt-
ic 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)
ispropyle alchohol (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 B+ voltage interlocks with which
instruments covered by this service data might be equipped.
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.)
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.

LC48/B-LC47/B/K
Use Soldering Iron to Pry Leads
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 10). 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 wirebristle (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, suctiontype 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 sodering 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.
2. Draw away the melted solder with an anti-static suction-type sol
der 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/Replacement
1. Heat and remove all solder from around the transistor leads.
2. Remove the heatsink mounting screw (if so equipped).
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.
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.
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 possilbe 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.
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. 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.
LC48/B-LC47/B/K
At Other Connections
Use the following technique to repair defective copper pattern at con-
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 area 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.
nections other than IC Pins. This technique involves the installation
of a jumper wire on the component side of the circuit board.
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 the 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.

LC48/B-LC47/B/K
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

i POWER light
This light is on during normal operation.
Light Blinking Slowly (2 seconds): television lamp is cooling down. It takes 12-15 seconds to warm up and about 2 minutes to cool
down.
j TEMP indicator
This light is off during normal operation.
If this indicator is lit, the optic unit is too hot. If this indicator is blinking, the cooling fan has stopped. Please call service.
k LAMP indicator - NORMAL OPERATION INDICATOR IS OFF
If light is lit, the lamp has failed. See page 19-22 for lamp replacement procedure. Consult your Hitachi dealer for proper part.
If light is blinking, lamp cover is not assembled securely after replacement.
IMPORTANT NOTES:
1. A small number of missing, discolored, or lit all the time dots or pixels is characteristic of TFT LCD technology due to the
manufacturing process irrespective of manufacturer.
2. Since LCD Rear PTV incorporates a high pressure lamp to display an image, it may take about one minute for the picture to
become stable, after the power has been turned on. After extended use, the picture may darken, the color may look unusual,
or the lamp “goes out,” (burns out). You may hear a “pop” sound when the lamp “goes out.” These are common
characteristics of the lamp, and should not be considered defective.
3. LCD Rear PTV incorporates an advanced cooling fan system to prevent from overheating. If you hear the cooling fan, it should
not be considered defective.
4. If you hear a “cracking” sound from the TV cabinet, it is due to the TV’s cabinet expanding and contracting due to room
temperature changes. It has no effect on the TV’s functions.
