USE CAUTION WHEN HANDLING THE LCD PANEL
When repairing the LCD panel, be sure you are grounded by using a wrist band.
When installing the LCD panel on a wall, the LCD panel must be secured using the 4 mounting holes on the rear
cover.
To avoid damaging the LCD panel:
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 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.
9. Protect the panel from ESD to avoid damaging the
electronic circuit (C-MOS).
10. During the repair, DO NOT leave the Power On for
more than 1 hour while the TV is face down on a
cloth.
CLEANING THE LCD PANEL
CAUTION: When cleaning the TV, be sure to unplug the power cord to avoid any chance of electric shock.
Clean the cabinet of the TV with a dry soft cloth.
Wipe the LCD screen gently with a soft cloth.
Stubborn stains may be removed with a cloth slightly moistened with a solution of mild soap and warm water.
If using a chemically pretreated cloth, please follow the instruction provided on the package.
Never use strong solvents such as a thinner, alcohol or benzine for cleaning.
Periodic vacuuming of the ventilation openings is recommended to ensure proper ventilation.
Do Not use paper towels, any type of abrasive pad, rags, rubber or vinyl materials to clean the screen. Using
these materials could easily scratch the screen which may result in permanent damage.
Do Not use any cleaning product containing alkaline/acid cleaner, scouring powder, or volatile solvent, such as
alcohol, ammonia, benzine, thinner or insecticide. Using any of these harsh cleaners may result in permanent
damage to the screen.
Do Not spray water or detergent directly onto the TV screen . If liquid drips into the bottom of the screen it may
cause a failure.
SETTING UP AND CARRYING THE TV
• Disconnect all cables when carrying the TV.
• Carry the TV with the adequate number of people; larger size TVs require two or more people.
• Correct hand placement while carrying the TV is very important for safety and to avoid damage.

SAFETY CHECK-OUT
Trouble Light
Chassis: RB2G, HE-L
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”.
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.

Earth Ground
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
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)

servicing of these boards requires special precautions to be taken as
outlined below.

It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints.
Lead Free Solder is available under the following part numbers :

62-500-046- m7 m6. g1 K00.1
to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees celsius.
requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
HANDLING THE FLEXIBLE FLAT CABLE (FFC)
When you connect / disconnect the FFC, please hold
Reinforcement Plastic and FFC Cable as shown below:
GOOD
Connect LVDS
holding both the
FFC Cable and
reinforcement
plastic.
GND Shield must be facing up
Terminal Side must be facing down
GOOD
DO NOT pull
or insert
LVDS holding
only from the
reinforcement
plastic.
NOT
To avoid any damage to the Connector and/or the FFC Cable
follow the steps show:
Press and Hold both Release Buttons at
the sametime to Pull out/ connect FFC
Release Buttons
from CN8700
If pulled without pressing both Release
Buttons, FFC Connector will break on
CN8700. This will cause 5X Blinking error.
