1. SAFETY PRECAUTION
IMPORTANT NOTICE
WARNING:
You are requested that you shall not modify or alter the information or data pro-
vided herein without prior written consent by SHARP. SHARP shall not be liable to
anybody for any damages, losses, expenses or costs, if any, incurred in connection
with or as a result of such modication or alteration.
THE INFORMATION OR DATA HEREIN SHALL BE PROVIDED “AS IS”WITHOUT ANY
WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED WARRANTY OF MER-
CHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
SHARP shall not be liable for any damages, losses, expenses or costs, if any, in-
curred in connection with or as a result of use of any information or data provided
herein.

IMPORTANT SERVICE SAFETY PRECAUTION
Service work should be performed only by qualied service technicians who are thoroughly
familiar with all safety checks and the servicing guidelines which follow:
WARNING
1. For continued safety, no modication of any circuit should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE RECEIVER (Fire & Shock Hazard)
Before returning the receiver to the user, perform the following safety checks:
3. 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.
4. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabi-
net backs, adjustment and compartment covers or shields, isolation resistor-capacitor net-
works, mechanical insulators, etc.
5. 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.
• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-eled by a 0.15μF capacitor
in series with all exposed metal cabinet parts and a known earth ground, such as electrical
conduit or elec-trical 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 resistor.
• 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, 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 0.74 Vrms (this corre-
sponds to 0.5 mA rms AC.) or more is excessive and indicates a potential shock hazard
which must be corrected before returning the monitor to the owner.

SAFETY NOTICE
Many electrical and mechanical parts in LCD colour television have special safety-related charac-
teristics.
These characteristics are often not evident from visual inspection, nor can protection aorded
by them be necessarily increased by using replacement components rated for higher voltage,
wattage, etc.
Replacement parts which have these special safety characteristics are identied in this manual;
electrical components having such features are identied by “ ” and shaded areas in the Re-
placement Parts List and Schematic Diagrams.
For continued protection, replacement parts must be identical to those used in the original cir-
cuit.
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,
re or other hazards.
Service work should be performed only by qualied service technicians who are thoroughly familiar
with all safety checks and the servicing guidelines.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
Employing lead-free solder
• “PWBs”of this model employs lead-free solder. The LF symbol indicates lead-free solder,
and is attached on the PWBs and service manuals. The alphabetical character following LF
shows the type of lead-free solder.
Example:
Using lead-free wire solder
• When xing the PWB soldered with the lead-free solder, apply lead-free wire solder. Re-
pairing with conventional lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C,
we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain
lead-free wire solder or soldering bit, contact our service station or service branch in your area.
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than
the conventional lead solder by 40 °C, and as it has poor solder wettability, you may be apt
to keep the soldering bit in contact with the PWB for extended period of time. However,
Since the land may be peeled o or the maximum heat-resistance temperature of parts
may be exceeded, remove the bit from the PWB as soon as you conrm the steady solder-
ing condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded.
Make sure to turn on and o the power of the bit as required.
If a dierent type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder.
Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, le it with steel wool or ne sandpa-
per.
Indicates lead-free solder of tin, silver and copper.
LF a
Indicates lead-free solderof tin, silver and nickel.
LF n

END OF LIFE DISPOSAL
A. Information on Disposal for Users (private house-
holds)
1. In the European Union
Attention: If you want to dispose of this equipment, please do
not use the ordinary dust bin!
Used electrical and electronic equipment must be treated sep-
arately and in accordance with legislation that requires proper
treatment, recovery and recycling of used electrical and electron-
ic equipment.
Following the implementation by member states, private house-
holds within the EU states may return their used electrical and
electronic equipment to designated collection facilities free of
charge*. In some countries* your local retailer may also take back
your old product free of charge if you purchase a similar new one.
* Please contact your local authority for further details.
If your used electrical or electronic equipment has batteries or
accumulators, please dispose of these separately beforehand according to local requirements.
By disposing of this product correctly you will help ensure that the waste undergoes the neces-
sary treatment, recovery and recycling and thus prevent potential negative eects on the envi-
ronment and human health which could otherwise arise due to inappropriate waste handling.
