Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing• Keep the temperature of the soldering iron around 270 ˚C dur-

ing repairing.• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering

or unsoldering.

This appliance is classified as a CLASS 1 LASER product.The CLASS 1 LASER PRODUCT MARKING is located onthe bottom.

CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous ra-diation exposure.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTEDLINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMSAND IN THE PARTS LIST ARE CRITICAL TO SAFEOPERATION. REPLACE THESE COMPONENTS WITHSONY PARTS WHOSE PART NUMBERS APPEAR ASSHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-LISHED BY SONY.

ATTENTION AU COMPOSANT AYANT RAPPORTÀ LA SÉCURITÉ!

LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTEDES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉDE FONCTIONNEMENT. NE REMPLACER CES COM-POSANTS QUE PAR DES PIÈCES SONY DONT LESNUMÉROS SONT DONNÉS DANS CE MANUEL OUDANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.

SAFETY CHECK-OUTAfter correcting the original service problem, perform the follow-ing safety check before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs,screws, and all other exposed metal parts for AC leakage.Check leakage as described below.

LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn 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 theseinstruments.

2. A battery-operated AC milliammeter. The Data Precision 245digital 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” indica-tion is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-amples of a passive VOM that is suitable. Nearly all batteryoperated digital multimeters that have a 2 V AC range are suit-able. (See Fig. A)

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro-static break-down because of the potential difference generatedby the charged electrostatic load, etc. on clothing and the humanbody.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focusedon the disc reflective surface by the objective lens in the opticalpick-up block. Therefore, when checking the laser diode emis-sion, observe from more than 30 cm away from the objective lens.

NOTE:• Due to standardization, replacements in the

parts list may be different from the parts speci-fied in the diagrams or the components usedon the set.

• -XX and -X mean standardized parts, so theymay have some difference from the originalone.

• RESISTORSAll resistors are in ohms.METAL: Metal-film resistor.METAL OXIDE: Metal oxide-film resistor.F: nonflammable

• Items marked “*” are not stocked since theyare seldom required for routine service.Some delay should be anticipated when order-ing these items.

• SEMICONDUCTORSIn each case, u: µ, for example:uA. . : µA. . uPA. . : µPA. .uPB. . : µPB. . uPC. . : µPC. .uPD. . : µPD. .
