IMPORTANT SERVICE SAFETY PRECAUTION
JService work should be performed only by qualified service technicians who are throughly familiar with all
safety checks and the servicing guidelines which follow:
WARNING
1. For continued safety, no modification of any circuit should be
attempted.
2. Disconnect AC power before servicing.
3. Semiconductor heat sinks are potential shcok hazards when
the chassis is operating.
4. The chassis in this receiver has two ground systems which are
separated by insulating material. The non-isolated (hot)
ground system is for the B+ voltage regulator circuit and the
horizontal output circuit. The isolated ground system is for the
low B+ DC voltages and the secondary circuit of the high
voltage transformer.
To prevent electrical shock use an isolation transformer
between the line cord and power receptable, when servicing
this chassis.
SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE
TUBE
When servicing the high voltage system, remove the static
charge by connecting a 10k ohm resistor in series with an
insulated wire (such as a test probe) between the picture
tube ground and the anode lead. (AC line cord should be
disconnected from AC outlet.)
1. Picture tube in this receiver employs integral implosion
protection.
2. Replace with tube of the same type number for continued
safety.
3. Do not lift picture tube by the neck.
4. Handle the picture tube only when wearing shatterproof
goggles and after discharging the high voltage anode
completely.
F
4A 125V
CAUTION: FOR CONTINUED
PROTECTION AGAINST A
RISK OF FIRE, REPLACE
ONLY WITH SAME TYPE 4A-
125V FUSE.
X-RADIATION AND HIGH VOLTAGE LIMITS
1. Be sure all service personnel are aware of the procedures and
instructions covering X-radiation. The only potential source of
X-ray in current solid state TV receivers is the picture tube.
However, the picture tube does not emit measurable X=Ray
radiation, if the high voltage is as specified in the ÒHigh
Voltage CheckÓ instructions.
It is only when high voltage is excessive that X-radiation is
capable of penetrating the shell of the picture tuve including
the lead in the glass material. The important precaution is to
keep the high voltage below the maximum level specified.
2. Is is essential that servicemen have available at all times an
accurate high voltage meter.
The calibration of this meter should be checked periodically.
3. High voltage should always be kept at the rated value - no
higher. Operation at higher voltages may cause a failure of
the picture tube or high volate circuity and also, under certain
conditions, may produce radiation in exceeding of desirable
levels.
4. When the high voltage regulator is operating properly there is
no possibility of an X-radiation problem. Every time a color
chassis is serviced, the brightness should be tested while
monitoring the high voltage with a meter to be certain that the
high voltage does not exceed the specified value and that it is
regulating correctly.
5. Do not use a picture tube other than that specified or make
unrecommended circuit modifications to the high voltage
circuitry.
6. When trouble shooting and taking test measurements on a
receiver with excessive high voltage, avoid being
unnecessarily close to the receiver.
Do not operate the receiver longer than is necessary to locate
the cause of excessive voltage.

BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)
Before returning the receiver to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the
chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control
knobs, insulating materials, cabinet backs, adjustment
and compartment covers or shields, isolation resistor-
capacity networks, mechanical insulators and etc.
3. To be sure that no shock hazard exists, check for leakage
current in the followingmanner.
¥ Plug the AC cord directly into a 120 volt AC outlet, (Donot
use an isolation transformer for this test).
¥ Using two clip leads, connect a 1.4k ohm, 10 watt resistor
paralleled by a 0.15mF capacitor in series with all
exposed metal cabinet parts and a known earth ground,
such as electrical conduit or electrical ground connected
to earth ground.
¥ Use an AC voltmeter having with 5000 ohm per volt, or
higher, sensitivity to measure the AC voltage drop across
the resistor.
IMPORTANT SERVICE SAFETY PRECAUTION
(Continued)
¥ Connect the resistor connection to all exposed metal
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon and etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC line cord plug
connection reversed. (If necessary, a non-polarized
adapter plug must be used only for the purpose of
completing these checks.)
Any current measured must not exceed 0.5 milliamp. Any
measurements not within the limits outlined above
indicate of a potential shock hazard and corrective action
must be taken before returing the instrument to the
customer.
SAFETY NOTICE
many electrical and mechanical parts in television receivers
have special safety-related characteristics. These
characteristics are often not evident from visual inspection,
nor can protection afforded by them be necessarllity
increased by using replacement components rated for
higher voltage, wattage, and etc. Replacement parts which
have these special safety characteristics are identified in
this manual; electrical components having such features are
identified by and shaded areas in the Replacement Parts
Lists and Schematic Diagrams.
For continued protection, replacement parts must be
identical to those used in the origianl circuit. The use of
substitute replacement parts which do not have the same
safety characteristics as the factory recommended
replacement parts shown in this service manual, may create
shock, fire, X-radiation or other hazards.

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, Sharp
approved type.
When troubleshooting and making test measure-
ments in a receiver with a problem of excessive high
voltage, avoid being unnecessarily close to the pic-
ture 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 Ð 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
manufacturerÕs warranty and may make you, the
servicer, responsible for personal injury or property
damage resulting therefrom.
4. Picture Tube Implosion Protection Warning Ð 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 Ð 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 Ð 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-of-
plate, 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 Ð 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 Sharp 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 replace-
ment part in Sharp 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
Sharp service literature. A subscription to, or
additional copies of service literature may be obtained
at a nominal charge from Sharp.

CAUTION: Before servicing instruments covered by this
service data and its supplements and addenda, read and
follow the SAFETY PRECAUTIONS 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 instrumentAC power cord from theAC
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 400MW
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 applyAC power to this instrument and/or any of its
electrical assemblies unless all solid-state device heat-
sinks 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 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 can 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
SERVICING PRECAUTIONS

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 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 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 Sharp 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.

8
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 Òlift-
off,Ó 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 Sharp 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 ÒUÓ 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 1.6KΩresistor, 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.

SET UP
SET UP
Your SHARP 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 ÒconvergenceÓ.
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, SHARP incorporates a feature to allow you to display a test pattern of 1 horizontal and 1 vertical line at the
center of the screen. Simply use the remote control to adjust the red and blue colors to match the green. When properly aligned, the
outputs of all three tubes should be directly over each other to produce the white lines.
To enter this adjustment mode, you may also select CONVERGENCE ADJ. from the Set Up menu. However, this will display a message
prompting you to press the front panel SCREEN ADJ. button.
NOTES: 1. Only a momentary press of the SCREEN ADJ. button is necessary to enter CONVERGENCE ADJUST mode.
2. The color being adjusted will blink (red or blue) to indicate color you are adjusting.
3. To save your adjustment data into memory, press the front panel SCREEN ADJ. button. If you do NOT wish to save
your adjustment data into memory, turn the TV OFF. When the TV is turned ON again, your old convergence data
will be restored.
