CHAPTER B
WARNNING
This service information is designed for experienced repair technicians only and is not
designed for use by the general public.
It does not contain warnings or cautions to advise non-technical individuals of
potential dangers in attempting to service a product.
Products powered by electricity should be serviced or repaired only by experienced
professional technicians.
Any attempt to service or repair the product or products dealt within this service
information by anyone else could result in serious injury or death.

CHAPTER C
SAFETY PRECAUTIONS
1. Caution
No modification of any circuit should be attempted. Service work should only be performed after you
are through familiar with all of the following safety checks and servicing guide lines.
2. Safety check
Care should be taken while servicing this LCD display. Because of the high voltage used in the
inverter circuit. These voltage are exposed in such areas as the associated transformer circuits.
3. Power supply requirements
The internal power converter with the attached AC power cord is necessary for the LCD monitor. Any
attempt to replace another power converter could result in serious of problems on the display.
4. Leakage current hot check
4-1 Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during this check.
4-2 Connect a 1500 ohm, 10 watt resistor, paralleled by a 0.15uF capacitor between each metallic
part and a good earth ground.
4-3 Use an AC voltmeter with 1000 ohm / volt or more sensitivity and measure the AC voltage across
the combination 1500 ohm resistor and 0.15uF capacitor.
4-4 Move the resistor connection to each exposed metallic part and measure the voltage.
4-5 Reverse the polarity of the AC plug in the AC outlet and repeat the above measurement.
4-6 Voltage measured must not exceed 1.5 volt RMS, from any exposed metallic part to the ground.
A leakage current tester may be used in the above hot check, in which case any circuit measured
must not exceed 1 milliamp. In the case of a measurement exceeding the 1 milliamp value, a rework is
required to eliminate the chance of a shock hazard.
