CAUTIONS AND WARNINGS
CAUTION!!
These servicing instructions are for use by qualified service personnel only.
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.
WARNING!!
An isolation transformer should be used during any service to avoid possible shock hazard, in case of live chassis.
! SAFETY-RELATED COMPONENT WARNING!!
There are critical components used in LCD color TVs that are important for safety. These components are identified with shading and ! mark on the schematic diagrams and the parts list. It is essential that these critical parts be replaced only with the part number specified in the parts list to prevent electric shock, fire 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 warranty.
ATTENTION!!
For safety reasons, component level repair of the Power Supply Boards and/or the Inverter Boards is prohibited.
ATTENTION!!
Ces instructions de service sont à l’usage du personnel de service qualifié seulement. Pour prévenir le risque de choc électrique, ne pas faire l’entretien autre que celui contenu dans le Mode d’emploi à moins que vous soyez qualifié faire ainsi.
ALERTE!!
Afin d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout dépannage.
!ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
Les composants identifies par une trame et par une marque ! sur les schemas de principe, les vues explosees et les listes de pieces sont d’une importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont l’importance est critique pour la securite du fonctionnement sont identifies dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.
ATTENTION!!
Pour des raisons de sécurité, Interdire de réparer ou remplacer les composantes dans les blocs d’alimentation et/ou sur les modules d’inverseur.

CAUTIONS AND WARNINGS
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 in “Leakage Test”.
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.
Follow the manufacturers’ instructions provided with the tester.
2.A battery-operated AC milliammeter.
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. Nearly all battery-operated digital multimeters that have a 2 VAC range are suitable. (see Figure A)

Earth Ground
Figure A. Use an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
The cover-plate retaining screw on most AC outlet boxes is at earth ground. Verify the AC outlet box retaining screw ground by connecting a 60W to
100W incandescent (not a neon or fluorescent 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)

SECTION 2 - TROUBLESHOOTING
Self Diagnosis
Supported model
DIAGNOSING THE ERROR
Before servicing the Television:
1.Verify the TV has the symptom the customer indicated.
2.Check to see if the latest Software is installed. a. If not, install the latest version.
3.Determine the replacement part required.
VIEWING THE SELF CHECK DIAGNOSIS HISTORY
When an error is detected, the Self Check screen records the number of times the error occurred. This is helpful in confirming past occurrences of an error and for determining if an error is intermittent when the customer is not sure what is causing the television to shut down. If the screen displays a “0”, no error has occurred.
1. Press POWER to turn on the TV and then turn it off again.
2.Press the following buttons on the Remote Commander within 1 second of each other:
