SAFETY NOTES
SECTION 1
1-2. Caution Handling of LCD Panel
Whenrepairing the LCD Panel, make sure you are groundedwith a wrist band.
Whenrepairing the LCD Panel on the wall, the panel must be securedusing the
4 mounting holes on the rear cover.
1) Do not press the panelor frame edge to avoid the risk of electric shock.
2) Do not scratch or press on the panelwith any sharp objects.
3) Do not leave the module in high temperature or in areas of high humidity for
an extendedperiod of time.
4) Do not expose the LCD panel to direct sunlight.
5) Avoid contactwith water. It may cause short circuit within the module.
6) Disconnectthe AC power when replacing the backlight (CCFL) or 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 connectorsof 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 PowerOn or Burn-in period for more
than 1 hourwhile the TV is face down on a cloth.
1-1. Warnings and Caution
1) These servicing instructions are for use by qualified service personnelonly.
2) To reduce the risk of electric shock, do not performany servicing other than
that contained in the operating instructionsunless you are qualified to do so.
3) An isolation transformershould be used during any service to avoid
Possible shock hazard, becauseof live chassis. The chassis of this receiver is
directly connectedto the ac power line.
4) Be sure to follow these guidelines to protectyour property and
avoid causing serious injury :
• Carry the TV with an adequatenumber of people; larger size TVs require
two or more people.
• Correct hand placement while carrying the TV is very important for
safety and to avoid damages.
5) Componentsidentifiedby shading and mark on the exploded views,
and in the parts list are critical forsafe operation.Replace these
componentswith Sony parts whose part numbers appear as shown in this
manualor in supplementspublished by Sony. Circuit adjustmentsthat are
critical forsafe operation are identifiedin this manual. Follow these
procedureswhenevercritical componentsare replaced or improper
operation is suspected.

1-4.Leakage Test
The AC leakage fromany exposed metal part to earth ground and fromall
exposedmetalparts to any exposedmetal part having a return to chassis must
not exceed 0.5mA (500 microamperes).
Leakagecurrent can be measured by any one of the three methods:-
1) A commercial leakage tester such as the SIMPSON 229 or RCA WT540A.
Follow the manufacturersinstructionsto use thoseinstructions.
2) A battery-operatedAC milliampmeter The DATA PRECISION 245 digital
multimeter is suitable for this job.
3) Measuring the voltagedrop across a resistor by means of a VOM or battery
operatedAC voltmeter. The 'limit' indication is 0.75Vso analog meters must
havean accurate low voltage scale. The SIMPSON'S 250 and SANWASH-
63TRD are examples of passive VOMs that are suitable. Nearly all battery
operateddigital multimeter that have a 2 VAC range are suitable.
(see Figure 2.)
1-3 Safety Check-Out
Aftercorrecting the original service problem, performthe following
safetychecks beforereleasing 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 inter board wiring to ensure that no wires are pinched or
contact high-wattageresistors.
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 unauthorizedreplacement parts, particularly transistorsthat
were installed during a previous repair. Point them out to the customer and
recommend their replacement.
5) Look for parts which, thoughfunctioningshow 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, metalized knobs, screws and all
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.

1-6. Lead Free Information
The circuit boards used in thesemodels have been processed using Lead
Free Solder. The boards are identifiedby the LF logo located close to the
board designation.
1-5. How to Find a Good Earth Ground
1) A cold-water pipe is a guaranteedearth ground;the cover-plate retaining
screw on most AC outlet boxes is also at earth ground.
2) If the retaining screw is to be used as your earth ground,verify that it is at
groundby measuring the resistancebetween it and a cold-waterpipe with an
ohmmeter.The reading should be zero ohms.
3) If a cold-water pipe is not accessible, connecta 60- to 100-watt trouble-
light (not a neon lamp) between the hot side of the receptacleand 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).
Figure 3. Checking for earth ground.
Figure 4: LF Logo Figure 5: LF logo on circuit board
The servicing of these boards requires special precautions.It is strongly
recommendedto use Lead Free Soldermaterial in orderto guaranteeoptimal
quality of new solder joints.
1-7. Handling the FLEXIBLE FLAT CABLE (FFC)
When you insert / pull out FFC, please grasp a reinforcementboard and main body of
FFC.
