* The signals from LINE OUT (AUDIO 1, 2) connectors and 5.1 ch L, R

connectors are measured. When you play the PCM sound tracks with

96 kHz sampling frequency, the output signals from the DIGITAL OUT

(OPTICAL, COAXIAL) are converted to 48 kHz (sampling frequency).

Design and specifications are subject to change without notice.

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

instruments.

2. A battery-operated AC milliammeter. 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" indica-

tion is 0.75V, 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 battery

operated digital multimeters that have a 2V AC range are suit-

able. (See Fig. A)

WARNING!!

WHEN SERVICING, DO NOT APPROACH THE LASER

EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS

NECESSARY TO CONFIRM LASER BEAM EMISSION,

BE SURE TO OBSERVE FROM A DISTANCE OF

MORE THAN 25 cm FROM THE SURFACE OF THE

OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.

CAUTION:

The use of optical instrument with this product will increase eye

hazard.

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ!

LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE

SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE

DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ

DE FONCTIONNEMENT. NE REMPLACER CES COM-

POSANTS QUE PAR DES PIÈCES SONY DONT LES

NUMÉROS SONT DONNÉS DANS CE MANUEL OU

DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.

1. Check the area of your repair for unsoldered or poorly-sol-

dered connections. Check the entire board surface for solder

splashes and bridges.

2. Check the interboard wiring to ensure that no wires are

"pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transis-

tors, that were installed during a previous repair. Point them

out to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and recom-

mend their replacement.

5. Check the line cord for cracks and abrasion. Recommend the

replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, "metallized" knobs,

screws, and all other exposed metal parts for AC leakage.

Check leakage as described below.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK

! OR DOTTED

LINE WITH MARK

! ON THE SCHEMATIC DIAGRAMS

AND IN THE PARTS LIST ARE CRITICAL TO SAFE

OPERATION. REPLACE THESE COMPONENTS WITH

SONY PARTS WHOSE PART NUMBERS APPEAR AS

SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-

LISHED BY SONY.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous ra-

diation exposure.
