USE CAUTION WHEN HANDLING THE LCD PANEL
When installing the LCD panel, be sure you are grounded by using
a wrist band.
When istalling the LCD panel on the wall, the LCD panel must be
secured using the 4 mounting holes on the rear cover.

When istalling the LCD panel on the wall, the LCD panel must be
secured using the 4 mounting holes on the rear cover.
1). do not press on the panel or frame edge to avoid the risk of
electric shock.
2). do not scratch or press on the panel with any sharp objects.
3). do not leave the module in high temperatures or in areas of high
humidity for an extended period of time.
4). do not expose the LCD panel to direct sunlight.
5). avoid contact with water. It may cause a short circuit within the
module.
6). disconnect the AC adapter when replacing the backlight (CCFL)
or inverter circuit.
(High voltage occurs at the inverter circuit at 650Vrms)
7). always clean the LCD panel with a soft cloth material.
8). use cere when handling the wires or connectors of the inverter
circuit. Damaging the wires may cause a short.
9). protect the panel from ESD to avoid damaging the electronic
circuit (C-MOS).

SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly soldered
safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly soldered
connections. Check the entire board surface for solder splashes
and bridges.
and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps, and
mounting hardware have been replaced. Be absolutely certain
that you have replaced all the insulators.
that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.

their replacement.
6. Check the line cords for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage. Check
leakage as described below.
leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA

instructions.
2. A battery-operated AC milliampmeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indica-
tion is 0.75 V, so analog meters must have an accurate low
voltage scale. The Simpson’s 250 and Sanwa SH-63TRD are
examples of passive VOMs that are suitable. Nearly all bat-
tery-operated digital multimeters that have a 2 VAC range are
suitable (see Figure A).
