IMPORTANT SERVICE SAFETY PRECAUTION
WAR NING
1. F or continued s a fe ty, no modific a tion of any c ircuit s hould be
a tte mpted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE RECEIVER (Fire &
Shock Hazard)
B efore returning the receiver to the us er, perform the following
safety checks:
3. Ins pect 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,
ins ula tion ma te ria ls , ca binet ba c ks , a djus tme nt a nd c ompa rtment
covers or s hields, is olation resis tor-capacitor networks, mechanical
ins ulators , etc.
5. To be sure that no shock hazard exists, check for leakage current in
the following manner.
• P lug the AC cord directly into a 110-240 volt AC outlet.
• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-
leled by a 0. 15 F capacitor in s eries with all expos ed 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, sen-
sitivity or measure the AC voltage drop across the resistor.
• C onnect the resis tor connection to all expos ed metal parts having a
return to the c ha s s is (a ntenna , meta l ca binet, s cre w hea ds , knobs
and control shafts, escutcheon, etc.) and measure the AC voltage
drop a cros s the re s is tor.
All checks must be repeated with the AC cord plug connection
revers ed. (If neces s ary, a nonpolarized adaptor plug mus t be us ed
only for the purpose of completing these checks.)
Any reading of 0.74 Vrms (this corresponds to 0.5 mA rms AC.) or
more is excessive and indicates a potential shock hazard which
mus t be c orre cted before returning the monitor to the owner.

SAFETY NOTICE
Many electrical and mechanical parts in LCD colour 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, etc.
R eplacement parts which have these special safety characteristics are
identified in this manual; electrical components having s uch features
are identified by " " and shaded areas in the R eplacement P arts List
and S chematic Diagrams.
For continued protection, replacement parts must be identical to those
us ed in the original circuit.
The us e of a substitute replacement parts which do not have the same
s a fe ty c ha ra c teris tic s a s the fa ctory re comme nde d re pla c eme nt pa rts
shown in this service manual, may create shock, fire or other hazards.

[2] PRECAUTION FOR USING LEAD-FREE
SOLDER
PRECAUTIONS FOR USING LEAD-FREE SOL-
DER
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 fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause dam-
age 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 qC, 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 qC which is higher than the conventional lead solder by 40 qC, 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 off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the
steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as
required.
If a different 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, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.
Lead-free wire solder for servicing
Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.
