CAUTION!!
These servicing instructions are for use by qualified service personnel only. 
To reduce the risk of electric shock, do not perform any servicing other than 
that contained in the operating instructions unless you are qualified to do so.
WARNING!!
An isolation transformer should be used during any service to avoid possible 
shock hazard, in case of live chassis. 
!
 
SAFETY-RELATED COMPONENT WARNING!!
There are critical components used in LCD color TVs that are important for 
safety. These components are identified with shading and 
!
 
mark on the 
schematic diagrams and the parts list. It is essential that these critical parts 
be replaced only with the part number specified in the parts list to prevent 
electric shock, fire or other hazard.
NOTE: Do not modify the original design without obtaining written permission 
from the manufacturer or you will void the original parts and labor warranty.
ATTENTION!!
For safety reasons, component level repair of the Power Supply Boards 
and/or the Inverter Boards is prohibited. 
CAUTIONS AND WARNINGS
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 
touching 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.
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.
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 other exposed metal parts for AC leakage. Check leakage 
as described in “Leakage Test”.

CAUTIONS AND WARNINGS
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.  
Follow the manufacturers’ instructions provided with the tester.
2.  A battery-operated AC milliammeter. 
3.  Measuring the voltage drop across a resistor by means of a VOM 
or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so 
analog meters must have an accurate low voltage scale. Nearly all 
battery-operated digital multimeters that have a 2 VAC range are 
suitable. (see Figure A)

Figure A. Use an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
The cover-plate retaining screw on most AC outlet boxes is at earth ground. 
Verify the AC outlet box retaining screw ground by connecting a 60W to 
100W incandescent (not a neon or fluorescent lamp) between the hot side of 
the receptacle and the retaining screw. Try both slots, if necessary, to locate 
the hot side on the line; the lamp should light at normal brilliance if the screw 
is at ground potential. (see Figure B)
