SAFETY-RELATED COMPONENTWARNING!!Replace all components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony.WARNINGS AND CAUTIONSSAFETY-RELATED COMPONENTWARNINGIt is essential that all critical parts be replaced only with the part number specified in the electrical parts list to prevent electric shock, fire, or other hazard.NOTE:Do not modify the original design without obtainingwritten permission from the manufacturer or you will void the original parts and labor guarantee.USE CAUTION WHEN HANDLING THE LCD PANEL When repairing the L CD panel, be sure you are grounded by using a wrist band.When repairing the LCD panel on the wall, the LCD panel must be secured using the 4 mounting holes on the rear cover.1)Do not press on the panel or frame edge to avoid the risk ofelectric shock.2)Do not scratch or press on the panel with any sharp objects.3)Do not leave the module in high temperatures or in areas ofhigh humidity for an extended period of time.4)Do not expose the LCD panel to direct sunlight.5)Avoid contact with water. It may cause a short circuit withinthe module.6)Disconnect the 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 connectors of the invertercircuit. Damaging the wires may cause a short.9)Protect the panel from ESD to avoid damaging the electroniccircuit (C-MOS).SAFETY CHECK-OUTAfter 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 poorlysoldered connections. Check the entire board surface forsolder 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, particularlytransistors, 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 obvioussigns of deterioration. Point them out to the customer andrecommend their replacement.6.Check the line cords for cracks and abrasion. Recommendthe 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 ACleakage. Check leakage as described below.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 0.5 mA (500 microamperes).Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 orRCA WT-540A. Follow the manufacturers’ instructions touse these instructions.2. A battery-operated AC milliampmeter. The Data Precision245 digital multimeter is suitable for this job.3.Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit”indication is 0.75 V, 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 multimeters that have a 2 V AC 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).FigureA. Using an AC voltmeter to check AC leakage. Figure B. Checking for earth ground.SELF DIAGNOSIS FUNCTIONThe units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED will automatically begin to flash.The number of times the LED flashes translates to a probable source of the problem.A definition of the STANDBY LED flash indicators is listed in the instruction manual for the user’s 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.1-1.DIAGNOSTIC TEST INDICATORSWhen an error occurs, the STANDBY LED will flash a set number of times to indicate the possible cause of the problem.If there is more than one error, the LED will identify the first of the problem areas.Result for all of the following diagnostic items are displayed on screen.If the screen displays a “0”, no error has occurred .Number of times STANDY LEDMonitoring Items Diagnostic Item Description(Red) flashes (Screen Display)2 times DC_DET Main power supply voltage error (12V, etc)3 times DC_ALERT1Malfunction of 3.3V line (Trident circuit, etc)4 times DC_ALERT2Malfunction of 5V line(Voltage Supply to FE, etc)5 times DC_ALERT3Malfunction of power supply for screen6 times BACKLIGHT Malfunction of inverter or overcurrent, etc7 times *2TEMPERATURE Abnormal temperature inside unit8 times AUDIOAudio circuit error (amplifier, etc.)9 times AUSD FAN *3Fan malfunction10 times DEFDigital FE circuit error11 times B-ENGINE Malfunction of Trident IC or around IC 12 times HFRBH board error *113 times(No item on screen display)Malfunction of balancer*1:When safety shutdown occurs because of FRC ACK, 1.5V line, 2.5V/3.3V line, or Panel 12V malfunction, BH board is consideredto be abnormal.*2:If abnormal temperature of BH board occurs, STANDY LED flashes is same as abnormal temperature inside unit, the error isdifferentiated by shot unit down or not.
