1-2. Caution Handling of LCD Panel
When repairing the LCD Panel, make sure you are grounded with a wrist band.
When repairing the LCD Panel on the wall, the panel must be secured using the
1-1. Warnings and Caution
1) These servicing instructions are for use by qualified service personnel only.
2) To reduce the risk of electric shock, do not perform any servicing other than 4 mounting holes on the rear cover.
1) Do not press 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 temperature or in areas of high humidity for
that contained in the operating instructions unless you are qualified to do so.
3) An isolation transformer should be used during any service to avoid
Possible shock hazard, because of live chassis. The chassis of this receiver is
directly connected to the ac power line.

temperature
or
in

for
an extended period of time.
4) Do not expose the LCD panel to direct sunlight.
5) Avoid contact with water. It may cause short circuit within the module.
4) Be sure to follow these guidelines to protect you

avoid causing serious injury :
• Carry the TV with an adequate number of people; larger size TVs require
two or more people.

6) Disconnect the AC power 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 care when handling the wires or connectors of the inverter circuit.

Safety Notes
1-4.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 5mA (500 microamperes)
1-3 Safety Check-Out
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:-
not
exceed
0
.
5mA
(500
microamperes)
.
Leakage current can be measured by any one of the three methods:-
1) A commercial leakage tester such as the SIMPSON 229 or RCA WT540A.
Follow the manufacturers instructions to use those instructions.
2) A battery-operated AC milliampmeter The DATA PRECISION 245 digital
multimeter is suitable for this job
1) Check the area of your repair for unsoldered or poorly soldered
connections. Check the entire board surface for solder splashes and bridges.
2) Check the inter board wiring to ensure that no wires are pinched or
contact high-wattage resistors.

.
3) Measuring the voltage drop across a resistor by means of a VOM or battery
operated AC voltmeter. The 'limit' indication is 0.75V 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 battery
operated digital multimeter that have a 2 VAC range are suitable

1-5. How to Find a Good Earth Ground
1) A cold-water pipe is a guaranteed earth ground; the cover-plate retaining
screw on most AC outlet boxes is also at earth ground.
2) If the retaining screw is to be used as your earth ground verify that it is at

ohmmeter. The reading should be zero ohms.
3) If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble-
