1-1. Caution Handling of LCD Panel
When repairing the LCD Panel, make sure you are grounded with a wrist band.
When repairing the LCD Panel on the wall, the panel must be secured using the 4
mounting holes on the rear cover.
1) Do not press 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 temperature 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 short circuit within the module.
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 circuit.
9) Protect the panel from ESD to avoid damaging the electronic circuit
(C-MOS).
10) During the repair, DO NOT leave the Power On or Burn-in period for more than
1 hour while the TV is face down on a cloth.
Figure 1. TV is face down on a cloth during reparing
3)Check all control knobs, shields, covers, ground straps and mounting
hardware have been replaced. Be absolutely certain 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.
,
other exposed metal parts for AC leakage. Check leakage test as described
next.
8. For safety reasons, repairing the Power board and/or Inverter board is prohibited.
1-3. 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
0.5mA (500 microamperes).
Leakage current can be measured by any one of the three methods:-
Follow the manufacturers instructions to use those 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 0.75V 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 2.)

.
1-2. 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 contact
high-wattage resistors.

1-4. 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 3).

c) Be sure to follow these guidelines to protect your property and avoid causing
serious injury.
• Carry the TV with an adequate number of people; larger size TVs require
• Correct hand placement while carrying the TV is very important for safety
and to avoid damages.
d) Components identified by shading and ! mark on the schematic diagrams,
exploded views, and in the parts list are critical for safe operation. Replace
this manual or in supplements published by Sony. Circuit adjustments that
are critical for safe operation are identified in this manual. Follow these
procedures whenever critical components are replaced or improper
operation is suspected.
1-6. Lead Free Information
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
3.
1-5. Warnings and Caution
a) These servicing instructions are for use by qualified service personnel only.
o 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.
b) An isolation transformer should be used during any service to avoid possible
shock hazard, because of live chassis. The chassis of this receiver is directly
connected to the ac power line.

The servicing of these boards requires special precautions. 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 high 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
