CAUTION!!
These servicing instructions are for use by qualified service ersonnel only.
To reduce the risk of electric shock, do not erform any servicing other than
that contained in the o erating instructions unless you are qualified to do so.
WARNING!!
An isolation transformer should be used during any service to avoid ossible
shock hazard, in case of live chassis.
!SAFETY-RELATED COMPONENT WARNING!!
There are critical com onents used in LCD color TVs that are im ortant for
safety. These com onents are identified with shading and !mark on the
schematic diagrams and the arts list. It is essential that these critical arts
be re laced only with the art number s ecified in the arts list to revent
electric shock, fire or other hazard.
NOTE: Do not modify the original design without obtaining written ermission
from the manufacturer or you will void the original arts and labor warranty.
ATTENTION!!
For safety reasons, com onent level re air of the Power Su ly Boards
and/or the Inverter Boards is rohibited.
CAUTIONS AND WARNINGS
SAFETY CHECK-OUT
After correcting the original service roblem, erform the following safety
checks before releasing the set to the customer:
1. Check the area of your re air for unsoldered or oorly soldered
connections. Check the entire board surface for solder s lashes
and bridges.
2. Check the interboard wiring to ensure that no wires are “ inched” or
touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground stra s and
mounting hardware have been re laced. Be absolutely certain that
you have re laced all the insulators.
4. Look for unauthorized re lacement arts, articularly transistors,
that were installed during a revious re air. Point them out to the
customer and recommend their re lacement.
5. Look for arts which, though functioning, show obvious signs of
deterioration. Point them out to the customer and recommend their
re lacement.
6. Check the line cords for cracks and abrasion. Recommend the
re lacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, “metallized” knobs, screws
and all other ex osed metal arts for AC leakage. Check leakage
as described in “Leakage Test”.

KDL-32R434A iii
CAUTIONS AND WARNIN S
LEAKAGE TEST
The AC leakage from any ex osed metal art to earth ground and from all
ex osed metal arts to any ex osed metal art having a return to chassis,
must not exceed 0.5 mA (500 microam eres). Leakage current can be
measured by any one of three methods.
1. A commercial leakage tester.
Follow the manufacturers’ instructions rovided with the tester.
2. A battery-o erated AC milliammeter.
3. Measuring the voltage dro across a resistor by means of a VOM
or battery-o erated AC voltmeter. The “limit” indication is 0.75 V, so
analog meters must have an accurate low voltage scale. Nearly all
battery-o erated digital multimeters that have a 2 VAC range are
suitable. (see Figure A)

(0.75V)
Figure A. Use an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
The cover- late 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 lam ) between the hot side
of the rece tacle and the retaining screw. Try both slots, if necessary, to
locate the hot side on the line; the lam should light at normal brilliance if
the screw is at ground otential. (see Figure B)

Before servicing the Television:
1. Verify the TV has the symptom the customer indicated.
2. Check to see if the latest Software is installed.
a. If not, install the latest version.
3. 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.
1. Press POWER to turn on the TV and then turn it off again.
2. Press the following buttons on the Remote Commander within 1
second of each other:
