CAUTION

These servicing instructions are for use by qualified servicepersonnel only.To reduce the risk of electric shock, do not perform any servicingother than that contained in the operating instructions unless youare qualified to do so.

WARNING!!

An isolation transformer should be used during any service toavoid possible shock hazard, because of live chassis.The chassis of this receiver is directly connected to the ac powerline.

! SAFETY-RELATED COMPONENTWARNING!!

Replace all components with Sony parts whose part numbersappear as shown in this manual or in supplementspublished by Sony.

WARNINGS AND CAUTIONS SAFETY-RELATED COMPONENTWARNING

It is essential that all critical parts be replaced only with the partnumber specified in the electrical parts list to prevent electricshock, fire, or other hazard.

NOTE: Do not modify the original design without obtainingwritten permission from the manufacturer or you willvoid the original parts and labor guarantee.

USE CAUTION WHEN HANDLING THE LCD PANEL

When repairing the LCD panel, be sure you are grounded byusing a wrist band.

When repairing the LCD panel on the wall, the LCD panel mustbe secured using the 4 mounting holes on the rear cover.1) Do not press on 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 temperatures or in areas of

high 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 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.)

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.9) Protect the panel from ESD to avoid damaging the electronic

circuit (C-MOS).

SAFETY CHECK-OUT

After correcting the original service problem, perform thefollowing 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 absolutelycertain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularlytransistors, that were installed during a previous repair. Pointthem 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 groundand from all exposed metal parts to any exposed metal parthaving a return to chassis, must not exceed 0.5 mA (500microamperes).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 accuratelow voltage scale.The Simpson’s 250 and Sanwa SH-63TRD are examples ofpassive VOMs that are suitable. Nearly all battery-operateddigital multimeters that have a 2 VAC range are suitable (seeFigure A).

How to Find a Good Earth GroundA cold-water pipe is a guaranteed earth ground; the cover-plateretaining screw on most AC outlet boxes is also at earth ground.If the retaining screw is to be used as your earth ground, verifythat it is at ground by measuring the resistance between it and acold-water pipe with an ohmmeter. The reading should be zeroohms.

If a cold-water pipe is not accessible, connect a 60- to 100-watttrouble- light (not a neon lamp) between the hot side of thereceptacle and the retaining screw. Try both slots, if necessary,to locate the hot side on the line; the lamp should light at normalbrilliance if the screw is at ground potential (see Figure B).

SELF DIAGNOSIS FUNCTION

The 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 toreveal past problems and how often these problems occur.

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 .
