ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!!
LESCOMPOSANTSIDENTIFIÉSPAR UNEMARQUE !SUR
LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES
PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE
FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS
QUE PAR DES PIÈCES SONY DONT LES NUMÉROS
SONT DONNÉS DANS CE MANUEL OU DANS LES
SUPPLÉMENTS PUBLIÉS PAR SONY.
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 PUBLISHED BY SONY.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety checks before releasing the set to the customer:
Checkthe antennaterminals, metal trim,“metallized” knobs,screws,
and all other exposed metal parts forAC leakage. Check leakage as
described below.
LEAKAGE
The AC leakage from any exposed metal part to earth Ground and
from all exposed metal parts to any exposed metal part having a
returnto chassis, mustnotexceed0.5mA (500 microampers).Leak-
age 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 aVOM
or battery-operatedAC voltmeter. The “limit” indication is 0.75
V, so analog meters must have an accurate low-voltage scale.
The Simpson 250 and Sanwa SH-63Trd are examples of a pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable. (See Fig. A)

ELECTRICAL PARTS LIST
• SEMICONDUCTORS
In each case, u: µ , for example:
uA...: µ A..., uPA...: µ PA..., uPB...: µ PB...,
uPC...: µ PC..., uPD...: µ PD...
• CAPACITORS
uF : µ F
• COILS
uH : µ H
• Abbreviation
CND : Canadian model
• Due to standardization, replacements in the parts list
may be different from the parts specified in the
diagrams or the components used on the set.
• -XX, -X mean standardized parts, so they may have
some difference from the original one.
• Items marked “*” are not stocked since they are
seldom required for routine service. Some delay
should be anticipated when ordering these items.
• RESISTORS
All resistors are in ohms
METAL: Metal-film resistor
METAL OXIDE: Metal Oxide-film resistor
F : nonflammable
Note:
Les composants identifiés par une
marque !sont critiques pour la
sécurité.
Ne les remplacer que par une
piéce portant le numéro spécifié.
The components identified by
mark !or dotted line with mark
!are critical for safety.
Replace only with part number
specified.
When indicating parts by reference
number, please include the board
name.
