SAFETY-RELATED COMPONENT WARNING
KDL-32EX600/40EX600/46EX600
There are critical components used in LCD color TVs that are important for safety. These components are identifi ed with shading and
mark on the schematic diagrams and the electrical parts list. It is essential that these critical parts be replaced only with the part number
specifi ed in the electrical parts list to prevent electric shock, fi re, 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 guarantee.
!
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:
do not press on the panel or frame edge to avoid the risk of electric shock.
do not scratch or press on the panel with any sharp objects.
do not leave the module in high temperatures or in areas of high humidity for an extended period of time.
do not expose the LCD panel to direct sunlight.
avoid contact with water. It may cause a short circuit within the module.
disconnect the AC adapter when replacing the backlight (CCFL) or inverter circuit.
(High voltage occurs at the inverter circuit at 650Vrms.)
always clean the LCD panel with a soft cloth material.
use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short.
protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).
during the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.

The circuit boards used in these models have been processed using
Lead Free Solder. The boards are identified by the LF logo located
close to the board designation e.g. H1 etc [ see example ]. The
servicing of these boards requires special precautions to be taken as
outlined below.
example
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 :

9 1 - 5 0 0 - 0 4 6 - 7m m 3 . 0g K 5 2 . 0

2 2 - 5 0 0 - 0 4 6 - 7m m 6 . 0g K 5 2 . 0
3 2 - 5 0 0 - 0 4 6 - 7m m 8 . 0g K 0 0 . 1
4 2 - 5 0 0 - 0 4 6 - 7m m 0 . 1g K 0 0 . 1
5 2 - 5 0 0 - 0 4 6 - 7m m 2 . 1g K 0 0 . 1
6 2 - 5 0 0 - 0 4 6 - 7m m 6 . 1g K 0 0 . 1
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade.
This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

SAFETY CHECK-OUT
To E
l
KDL-32EX600/40EX600/46EX600
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 below.
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, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instructions.
2. A battery-operated AC milliampmeter. The Data Precision 245
digital multimeter is suitable for this job.
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.
The Simpson’s 250 and Sanwa SH-63TRD are examples of
passive VOMs that are suitable. Nearly all battery-operated digital
multimeters that have a 2 VAC range are suitable (see Figure A).
How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate
retaining screw on most AC outlet boxes is also at earth ground. If the
retaining screw is to be used as your earth ground, verify that it is at
ground by measuring the resistance between it and a cold-water pipe
with an ohmmeter. The reading should be zero ohms.
If a cold-water pipe is not accessible, connect a 60- to 100-watt
trouble- light (not a neon 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).
