SAFETY NOTICE
Many electrical and mechanical parts in television have
special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily 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“ å”
and shaded areas in the
Replacement Parts List and
Schematic Diagrams.
For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a 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 or other hazards.

WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNINGTHE 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, and check 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, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators and etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
»Plug the AC cord directly into a 110~240 volt AC outlet,
and connect the DC power cable into the receiver's
DC jack.(Do not use an isolation transformer for this
test).
»Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series
with all exposed metal cabinet parts and a known
earth ground, such as electrical conduit or electrical
ground connected to an earth ground.
»Use an AC voltmeter having with 5000 ohm per volt,
or higher, sensitivity or measure the AC voltage drop
across the resisor.
»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 cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 35V peak (this corresponds to 0.7
milliamp. peak AC.) or more is excessive and
indicates a potential shock hazard which must be
corrected before returning the monitor to the owner.

SAFETY PRECAUTIONS
NOTICE :Comply with all cautions and safety related notes
located on or inside the cabinet and on the chassis.
The following precautions should be observed :
1. When service is required, even though the PDP UNIT an
isolationtransformershouldbeinserted between the power
line and the set in safety before any service is performed.
2. When replacing a chassis in the set, all the protective
devices must be put back in place, such as barriers,
nonmetallic knobs, adjustment and compartment
covershields, isolation resistor-capacitor, etc.
3. When service is required, observe the original lead dress.
Extra precaution should be taken to assure correct lead
dress in the high voltage circuitry area.
4. Always use the manufacture's replacement components.
Especially critical components as indicated on the circuit
diagram should not be replaced by other manufacture's.
Furthermore where a short circuit has occurred, replace
those components that indicate evidence of overheating.
5. Before returning a serviced set 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
set by the manufacture 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.
6. Perform the following precautions against unwanted
radiation and rise in internal temperature.
• Always return the internal wiring to the original styling.
• Attachparts(Gascket,FerriteCore, Ground,RearCover,
Shield Case etc.) surely after disassembly.
7. Perform the following precautions for the PDP panel.
• When the front case is removed, make sure nothing hits
the panel face, panel corner, and panel edge (so that the
glass does not break).
• Make sure that the panel vent does not break. (Check
that the cover is attached.)
• Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.
8. Pay attention to the following.
• Be sure to wire the fan. If the fan does not work, the
temperature will rise and cause the protection circuit to
operate.
• When the front case is removed, infrared ray is radiated
and may disturb reception of the remote control unit.
• Pay extreme caution when the front case and rear panel
are removed because this may cause a high risk of
disturbance to TVs and radios in the surrounding.

Leakage Current Cold Check
With the AC plug removed from an AC power source, place
a jumper across the two plug prongs. Turn the AC power
switch on. Using an insulation tester (DC 500V), connect one
lead to the jumpered AC plug and touch the other lead to each
exposed metal part (input/output terminals, screwheads,
metal overlays, control shafts, etc.), particularly any exposed
metal part having a return path to the chassis. Exposed metal
parts having a return path to the chassis should have a
minimum resistor reading of 0.3MΩand a maximum resistor
reading of 5MΩ. Any resistor value below or above this range
indicates an abnormality which requires corrective action.
Exposed metal parts not having a return path to the chassis
will indicate an open circuit.
Leakage Current Hot Check
Plug the AC line cord directly into an AC power source (do not
use an isolation transformer for this check).
Turn the AC power switch on.
Using a "Leakage Current Tester (Simpson Model 229
equivalent)", measure for current from all exposed metal
parts of the cabinet (input/output terminals, screwheads,
metal overlays, control shaft, etc.), particularly any exposed
metal part having a return path to the chassis, to a known
earthground(waterpipe,conduit,etc.). Anycurrentmeasured
must not exceed 0.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE SET TO THE CUSTOMER.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in SHARP set have
special safety related characteristics. These are often not
evident from visual inspection nor the protection afforded by
them necessarily can 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 by
marking with a on the schematics and on the parts list in
this Service Manual.
The use of a substitute replacement component which dose
not have the same safety characteristics as the SHARP
recommended replacement one, shown in the parts list in this
Service Manual, may create shock, fire 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 SHARP Service
Manual. A subscription to, or additional copies of, SHARP

while displaying PAL in the actual PDP.
This is temporary.
After adjustment, it becomes the W/B table 2 operation in the PAL input after restarted in the normal mode. It becomes an operation of the W/B
table 1 adjustment value after adjustment in the NTSC input.
As for the above example, table selection (No. 1 and 2) becomes the shipping setting.
