CAUTIONS AND WARNINGS

SETTING UPAND 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.

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.

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 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.

CAUTIONS AND WARNINGS

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.

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”.

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. Acommercial leakage tester.

Follow the manufacturers’ instructions provided with the tester.

2. Abattery-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 FINDAGOOD EARTH GROUND

The cover-plate retaining screw on mostAC outlet boxes is at earth ground.

Verify the AC outlet box retaining screw ground by connecting a 60W to

:LQFDQGHVFHQWQRWDQHRQRUÀXRUHVFHQWODPSEHWZHHQWKHKRWVLGHRI

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)
