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. H1 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 TIMER/PIC OFF 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 TIMER/PIC OFF 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 TIMER/PIC OFF 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.

2-1. RESETTING THE TV TO THE FACTORY DEFAULTSTraditional Service Mode is not available in this chassis. The only option for service technicians is to reset all of the settings to the Factory Default from the Self Diagnostic screen.

CAUTION: Resetting the TV to the Factory Defaults will over-write all customer settings. Before performing this reset, contact the customer to determine what adjustments they have made.

1. TV must be in standby mode. (Power off).2. Press the following buttons on the Remote Commander within a second of each other: DISPLAY Channel 5 Volume + TV POWER . The Self Check list displays. This is the SAME as accessing Service Adjustments.

Results for all of the following diagnostic items are displayed at the bottom of the screen. No error has occurred if the screen displays a 0.

3-1. CIRCUIT BOARDS LOCATION

3-2. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS 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.

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.

Les composants identi es per un trame et une marque ! sont critiques pour la securite. Ne les remplacer que par une piece portant le numero speci e.

Le symbole indique une fusible a action rapide. Doit etre remplace par une fusible de meme yaleur, comme maque.

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.
