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.
