SAFETY CHECK-OUT

CAUTION

These servicing instructions are for use by qualiﬁed service personnel onl

y. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are quali

ﬁed to do so.

WARNING!!

An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis.

The chassis of this receiver is directly connected to the ac power line.

! SAFETY-RELATED COMPONENT

WARNING!!

Components identiﬁed by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Son

y. Circuit adjustments that are critical for safe operation are identi

ﬁed in this manual. Follow these procedures whenever critical components are replaced or improper operation is suspected.

ATTENTION!!

Ces instructions de service sont à l’usage du personnel de service quali

ﬁé 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 quali

ﬁé faire

ainsi.

Aﬁn d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout dépannage. Le chássis de ce récepteur est directement raccordé à l’alimentation du secteu

! 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 Son

y. Les reglages de circuit dont l’importance est critique

pour la securite du fonctionnement sont identi

ﬁes dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.

After

correcting the original service problem, perform the fol-

lowing 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

2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors

3. Check that all control knobs, shields, covers, ground straps, and certain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularly transistors, them

5. Look for parts which, though functioning, show obvious signs recommend

6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer

7. Check the B+ and HV to see if they are specified values. Make your HV meter if sets always have low HV

8. Check the antenn a terminals, metal trim, “metallized” knobs, Leakage. Check leakage as described right

LEAKAGE TES

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal par 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

WT-540A. Follow the manufacturers’ instructions to

these instruments.

use

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

or battery-operated AC voltmeter. The “limit” indica-

is 0.75 V, so analog meters must have an accurate low-

tion voltage examples battery range are suitable. (See Fig. A

Note:

• All capacitors are in µF unless otherwise noted. (pF: µµF) Capacitors without voltage indication are all 50 V.

• Indication of resistance, which does not have one for rating electrical power, is as follows.

Pitch: 5 mm Rating electrical power 1/4 W (CHIP : 1/10 W)

• All resistors are in ohms.

• : nonflammable resistor.

• : fusible resistor.

• : internal component.

• : panel designation, and adjustment for repair.

• All variable and adjustable resistors have characteristic curve B, unless otherwise noted.

• : earth-ground.

• : earth-chassis.

• When replacing the part in below table, be sure to perform the related adjustment.

• All voltages are in V.

• Readings are taken with a 10 M digital multimeter.

• Readings are taken with a color-bar signal input.

• Voltage variations may be noted due to normal production tolerances.

•

• Circled numbers are waveform references.

• : B + bus.

• : B – bus.

• : Signal path.

Note: The components identified by shading and
