SAFETY NOTESSECTION 1

1-2. Caution Handling of LCD PanelWhen 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.

1-1. Warnings and Caution1) These servicing instructions are for use by qualified service personnel only.2) To reduce the risk of electric shock, do not perform any servicing other thanthat contained in the operating instructions unless you are qualified to do so.

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.

3) An isolation transformer should be used during any service to avoidPossible shock hazard, because of live chassis. The chassis of this receiver isdirectly connected to the ac power line.4) Be sure to follow these guidelines to protect your property andavoid causing serious injury :

4) Do not expose the LCD panel to direct sunlight.

5) Avoid contact with water. It may cause short circuit within the module.

6) Disconnect the AC power when replacing the backlight (CCFL) or

inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms)

g j y• Carry the TV with an adequate number of people; larger size TVs requiretwo or more people.• Correct hand placement while carrying the TV is very important forsafety and to avoid damages.5) Components identified by shading and mark on the exploded views!

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).

5) Components identified by shading and mark on the exploded views,and in the parts list are critical for safe operation. Replace thesecomponents with Sony parts whose part numbers appear as shown in thismanual or in supplements published by Sony. Circuit adjustments that arecritical for safe operation are identified in this manual. Follow these

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.

procedures whenever critical components are replaced or improperoperation is suspected.

Safety Notes

1 3 C ti Ab t th Lithi B tt3) 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 multimeter that have a 2 VAC range are suitable. 1-4. Safety Check-Out

1-3. Caution About the Lithium Battery1) Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.2) Outer case broken battery should not contact to water.

(see Figure 2.)After correcting the original service problem, perform the followingsafety checks before releasing the set to the customer:-1) Check the area of your repair for unsoldered or poorly solderedconnections. Check the entire board surface for solder splashes and bridges.2) Check the inter board wiring to ensure that no wires are pinched or) g pcontact high-wattage resistors.3)Check all control knobs, shields, covers, ground straps and mountinghardware have been replaced. Be absolutely certain you have replaced allthe insulators.4) Look for unauthorized replacement parts, particularly transistors that

Point them out to the customer andrecommend their replacement.5) Look for parts which, though functioning show obvious signs ofdeterioration. Point them out to the customer and recommend theirreplacement.6) Check the line cords for cracks and abrasion. Recommend the

1-6. How to Find a Good Earth Ground1) A cold-water pipe is a guaranteed earth 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 ground by measuring the resistance between it and a cold-water pipe with an ohmmeter The reading should be zero ohms)

replacement of any such line cord to the customer.7) Check the antenna terminals, metal trim, metalized knobs, screws and allother exposed metal parts for AC leakage. Check leakage test as describednext.8. For safety reasons, repairing the Power board and/or Inverter board isprohibited

ohmmeter. The reading should be zero ohms.3) 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).

prohibited.1-5.Leakage TestThe 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:-

Figure 3. Checking for earth ground.

g y y1) A commercial leakage tester such as the SIMPSON 229 or RCA WT540A.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.

Safety Notes

1-7. Lead Free InformationThe 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.

Please hold reinforcement board and plunge it to depths.

Please pull out FFC while pushing the button of both ends at the same time.
