CAUTIONS AND WARNINGS

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 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.

mark on the

ATTENTION!!

For safety reasons, component level repair of the Power Supply Boards and/or the Inverter Boards is prohibited.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer:

Check the area of your repair for unsoldered or poorly soldered

1. connections. Check the entire board surface for solder splashes

and bridges.

Check the interboard wiring to ensure that no wires are “pinched” or

2. touching high-wattage resistors.

Check that all control knobs, shields, covers, ground straps and

3. mounting hardware have been replaced. Be absolutely certain that

you have replaced all the insulators.

Look for unauthorized replacement parts, particularly transistors,

4. that were installed during a previous repair. Point them out to the

customer and recommend their replacement.

Look for parts which, though functioning, show obvious signs of

5. deterioration. Point them out to the customer and recommend their

replacement.

Check the line cords for cracks and abrasion. Recommend the

6. replacement of any such line cord to the customer.

Check the antenna terminals, metal trim, “metallized” knobs, screws

7. and all other exposed metal parts for AC leakage. Check leakage

as described in “Leakage Test”.

KDL-32R434A ii

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.

A commercial leakage tester.

1. Follow the manufacturers’ instructions provided with the tester.

A battery-operated AC milliammeter.

Measuring the voltage drop across a resistor by means of a VOM

3. 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)

To Exposed Metal Parts on Set

0.15 µF

Voltmeter (0.75V)

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)

DIAGNOSING THE ERROR

Before servicing the Television:

Verify the TV has the symptom the customer indicated.

1. Check to see if the latest Software is installed.

If not, install the latest version.

Determine the replacement part required.

VIEWING THE SELF CHECK DIAGNOSIS HISTORY

When an error is detected, the Self Check screen records the number of times the error occurred. This is helpful in confirming past occurrences of an error and for determining if an error is intermittent when the customer is not sure what is causing the television to shut down. If the screen displays a “0”, no error has occurred.

Press

1. Press the following buttons on the Remote Commander within 1

2. second of each other:
