SECTION 1

SA FETY NOTES

1-1. Warnings and Caution

1) 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 than that contained in the operating instructions unless you are qualified to do so.

3) 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.

4) 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 two or more people.

• Correct hand placement while carrying the TV is very important for safety and to avoid damages.

5) Components identified by shading and mark on the exploded views,

!

and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in 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.

1-2. Caution Handling of LCD Panel

When repairi ng the LCD Panel, make sure you are grounded w ith a wrist band. When repairi ng the LCD Panel on the wall, the panel must be secured using the 4 mounting hol es on the rear cover .

1) Do not press the panel or frame edge to avo id the risk of electr ic shock.

2) Do not scr atch or press on the panel w ith any sharp object s.

3) Do not leave the module in high temperat ure or in areas of high hum idity for an extended per iod of time.

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

5) Avoid contact with water . I t may cause short ci rcu it within the module.

6) Disco nnect the AC power when replaci ng the backl ight ( CCF L) or inverter cir cuit . (Hi gh voltage occur s at the inver ter ci rcui t at 650Vrms)

7) Always cl ean the LCD panel with a soft cloth mater ial .

8) Use care when handli ng the wir es or connectors of the inver ter ci rcui t. Damaging the w ir es may cause a short circu it.

9) Protect the panel from ESD to avoid damaging the elect roni c circuit (C-MOS).

10) Dur i ng the r epai r , DO NOT l eave the Pow er On or Burn-i n period for more than 1 hour w hil e the T V i s face dow n on a cloth.

Figure 1. TV is faced down on a cloth during repair.

Safety Notes

1-3. Caution About the Lithium Battery

1) Danger of explosion if battery is incorrectl y replaced. Replace only with the same or equivalent type.

2) Outer case broken battery shoul d not contact to water.

1-4. 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 inter board wiring to ensure that no wires are pinched or contact high-wattage resistors.

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.

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.

1-5.Leakage Test

The AC leakage from any exposed m etal par t to earth ground and from all exposed metal par ts to any exposed metal part having a retur n to chassi s must not exceed 0.5mA (500 micr oamperes) . Leakage cu rrent can be measur ed by any one of the three m ethods:-

1) A commerci al leakage t ester such as the SI M PSON 229 or RCA WT540A. Follow the manufacturers instr uctions to use those instruct ions.

2) A battery-operate d AC milliampmeter The DATA PRECISI ON 245 digital multimeter is suitable for this job.

3) Measu ring the volt age dr op across a resi stor by means of a VOM or battery operated AC voltmeter. The 'li mi t' indication is 0.75V so analog m eters m ust have an accurate low volt age scale. T he SIM PSON' S 250 and SANWA SH63TRD are exampl es of passi ve VOM s that are sui table. N early all battery operated digi tal mul timeter that have a 2 VAC range are sui table. (see Figur e 2.)

Figure 2. AC voltmeter to check AC leakage

1-6. How to Find a Good Earth Ground

1) A cold-water pi pe is a guaranteed ear th ground; t he cover-pl ate retaini ng screw on most AC outlet boxes i s also at earth ground.

2) If the retaining scr ew is to be used as your earth ground, veri fy that it is at ground by measur i ng the r esistance between it and a cold-w ater pi pe with an ohmmeter. T he readi ng should be zer o ohms.

3) I f a cold-w ater pi pe is not accessi ble, connect a 60- to 100-watt t roublelight (not a neon lamp) between the hot side of the recept acle and the retaining scr ew. Tr y both slots, if necessa ry, to locate the hot si de on the line; the l am p shoul d l i ght at normal br i l l i ance i f the screw is at gr ound pot enti al (see Figur e 3).
