1-1. 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 4 
mounting holes on the rear cover.
1) Do not press the panel or frame edge to avoid the risk of electric shock.
3)Check all control knobs, shields, covers, ground straps and mounting 
hardware have been replaced. Be absolutely certain 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 
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 
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.
6) Disconnect the AC power when replacing the backlight (CCFL) or
recommend their replacement.
5) Look for parts which, though functioning show obvious signs of deterioration. 
Point them out to the customer and recommend 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
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.  
Damaging the wires may cause a short circuit.
9) Protect the panel from ESD to avoid damaging the electronic circuit
7) Check the antenna terminals, metal trim, metallized knobs, screws and all 
other exposed metal parts for AC leakage. Check leakage test as described 
next.
8. For safety reasons, repairing the Power board and/or Inverter board is prohibited.
(C-MOS).
10) During the repair, DO NOT leave the Power On or Burn-in period for more than 
1 hour while the TV is face down on a cloth.
1-3. 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).
Leakage current can be measured by any one of the three methods:-
1 A commercial leakage tester such as the SIMPSON 229 or RCA WT-540A
1. A commercial leakage tester such as the SIMPSON 229 or RCA WT 540A. 
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.
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 multimeters that have a 2 VAC range are suitable. 
(see Figure 1.)
Figure 1. TV is faced down on a cloth during repair.
1-2. 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 connections.  
Check the entire board surface for solder splashes and bridges.
2) Check the interboard wiring to ensure that no wires are pinched or contact 
high-wattage resistors.
