SPECIFICATIONS AND PARTS ARE SUBJECT TO CHANGE FOR IMPROVEMENT

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.

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 an

! 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-recom-

mended replacement component, shown in the parts list in this

Service Manual, may create shock, fire, or other hazards.

Production safety is continuously under review and new instruc-

tions are issued from time to time. For the latest information,

always consult the current HITACHI Service Manual. A subscrip-

tion to, or additional copies of HITACHI Service Manuals may be

obtained at a nominal charge from HITACHI Sales Corporation.

Ultraviolet Radiation

OPTIC UNIT: The primary source of Ultraviolet Radiation in this

receiver is the optic unit. The optic unit utilized in this chassis is

specially constructed to limit Ultraviolet Radiation emissions. For

continued Ultraviolet Radiation protection, the replacement optic

unit must be the same type as the original HITACHI-approved

type.

Service Personnel - WARNING

Eye damage may result from directly viewing the light produced by

the lamp used in this product. Always turn off lamp before open-

ing optic unit. Ultraviolet radiation eye protection required during

servicing.

When troubleshooting and making test measurements in a receiv-

er with an excessive high voltage problem, avoid being unneces-

sarily close to the optic unit and the high voltage component.

Do not operate the chassis longer than is necessary to locate the

cause of excessive voltage.

This Service Manual is intended for qualified service techni-

cians; it is not meant for the casual do-it-yourselfer. Qualified

technicians have the necessary test equipment and tools, and

have been trained to properly and safely repair complex prod-

ucts such as those covered by this manual. Improperly per-

formed repairs can adversely affect the safety and reliability of

the product and may void warranty. Consumers should not risk

trying to do the necessary repairs and should refer to a quali-

fied service technician.

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 compo-

nents which contain lead in solder, avoid unprotected skin

contact with solder. Also, when soldering do not inhale any

smoke or fumes produced.

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 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 electri-

cal contacts by applying the following mixture to the contacts

with a pipe cleaner, cotton-tipped stick or comparable nonabra-

sive 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.

5. Do not apply AC power to this instrument and/or any of its elec-

trical assemblies unless all solid-state device heat-sinks are cor-

rectly installed.

6. Always connect the test instrument ground lead to the appropri-

ate instrument chassis ground before connecting the test instru-

ment 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 dis-

charging wrist strap device, which should be removed for poten-

tial 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 expo-

sure 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 sol-

der 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 electri-

cally 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 replace-

ment ES devices. (Otherwise harmless motion such as the

brushing together of your clothes fabric or the lifting of your foot

from a carpeted floor can generate static electricity sufficient to

damage an ES device.)

General Soldering Guidelines

1. Use a grounded-tip, low-wattage soldering iron and appropriate

tip size and shape that will maintain tip temperature within the

range 500°F to 600°F.

2. Use an appropriate gauge of resin-core solder composed of 60

parts tin/40 parts lead.

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

4. Thoroughly clean the surfaces to be soldered. Use a small wire-

bristle (0.5 inch or 1.25 cm) brush with a metal handle. Do not

use freon-propelled spray-on cleaners.

5. Use the following desoldering technique.

a. Allow the soldering iron tip to reach normal temperature

(500°F to 600°F).

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

draw away the melted solder with an anti-static, suction-

type solder removal device or with solder braid.

CAUTION: Work quickly to avoid overheating the circuit

board printed foil.

6. Use the following soldering technique.

a. Allow the 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.

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 follow-

ing 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.

Removal

1. Desolder and straighten each IC lead in one operation by gent-

ly 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 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 remain-

ing 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).

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 pos-

silbe 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

SERVICING PRECAUTIONS

Fuses and conventional Resistor Removal/Replacement

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

stake.

2. Securely crimp leads of replacement component around stake

1/8 inch from top.

3. Solder the connections.

CAUTION: Maintain original spacing between the replaced

component and adjacent components and the

circuit board, to prevent excessive component

temperatures.

Circuit Board Foil Repair

Excessive heat applied to the copper foil of any printed circuit board

will weaken the adhesive that bonds the foil to the circuit board,

causing the foil to separate from, or “lift-off” the board. The follow-

ing 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/cur-

rent 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 follow-

ing 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.

At Other Connections

Use the following technique to repair defective copper pattern at

connections other than IC Pins. This technique involves the instal-

lation 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 condi-

tion will not exist if the jumper wire opens.

2. Trace along the copper pattern from both wire sides of the pat-

tern break and locate the nearest component directly connected

to the affected copper pattern.

3. Connect insulated 20-gauge jumper wire from the nearest com-

ponent on one side of the pattern break to the lead of the near-

est 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 discon-

necting 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 sys-

tem, 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 compo-

nents.

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 capaci-

tor 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 identi-

cal 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 1.6K resistor, 0 = 0 (jumper).

Chip capacitors generally do not have the value indicated on

the capacitor. The color of the component indicates the gen-

eral 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 Flat-

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.
