SAFETY-RELATED COMPONENT WARNING
There are critical components used in LCD color TVs that are
important for safety. These components are identi 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 speci ed in the electrical parts list to prevent
electric shock, 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 PANELWhen 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).

The circuit boards used in these models have been processed
usingLead Free Solder. The boards are identified by the LF logo
locatedclose to the board designation e.g. U1 etc [ see example ].
Theservicing of these boards requires special precautions to be
taken asoutlined below.
example 1
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 :
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.
For more information on the use of Lead Free Solder, please
refer to http://www.sony-training.com

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 below.
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, 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
Simpsons 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 GroundA 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).

SELF-DIAGNOSTIC FUNCTION Self DiagnosisSupported model
The units in this manual contain a self-diagnostic function. If
an error occurs, the STANDBY LED indicator will automatically begin
to ash. The number of times the LED ashes translates to a probable
source of the problem. A de nition of the STANDBY LED ash
indicators is listed in the instruction manual for the users
knowledge and reference. If an error symptom cannot be reproduced,
the Remote Commander can be used to review the failure occurrence
data stored in memory to reveal past problems and how often these
problems occur.
1. Diagnostic Test Indicators
When an error occurs, the STANDBY LED indicator will ash a set
number of times to indicate the possible cause of the problem. If
there is more than one error, the indicator will identify the rst
of the problem areas.

INFORMATION
All capacitors are in F unless otherwise noted. pF : F 50WV or
less are not indicated except for electrolytics and tantalums.All
electrolytics are in 50V unless otherwise speci ed.All resistors
are in ohms. k=1000, M=1000kIndication of resistance, which does
not have one for rating electrical power, is as follows: Pitch :
5mm Rating electrical power : 1/ 4 W1/ 4 W in resistance, 1/10 W
and 1/16 W in chip resistance.
: non ammable resistor : fusible resistor
: internal component : panel designation and adjustment for
repair
: earth ground : earth-chassis
All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.Readings are taken with a color-bar
signal input.Readings are taken with a 10M digital
multimeter.Voltages are DC with respect to ground unless otherwise
noted.Voltage variations may be noted due to normal production
tolerances.All voltages are in V.S : Measurement impossibility.
: B+line.: B-line. (Actual measured value may be different).
: signal path. (RF)Circled numbers are waveform references.
NOTE: The components identi ed by a red outline and a mark
contain con dential information. Speci c instructions must be
adhered to whenever these components are repaired and/or replaced.
See Appendix A: Encryption Key Components in the back of this
manual.
The components identi ed by shading and ! symbol are critical
for safety. Replace only with part number speci ed.
The symbol indicates a fast operating fuse and is displayed on
the component side of the board. Replace only with fuse of the same
rating as marked.
