SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED
LINE WITH MARK 0ON 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.
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.
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.

• Items marked “*” are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering
these items.
• The mechanical parts with no reference num-
ber in the exploded views are not supplied.
• Accessories and packing materials are given
in the last of the electrical parts list.
NOTE:
• -XX and -X mean standardized parts, so they
may have some difference from the original

NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts speci-
fied in the diagrams or the components used
on the set.
• -XX and -X mean standardized parts, so they
may have some difference from the original
one.
• RESISTORS
All resistors are in ohms.
METAL: Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F: nonflammable
• Abbreviation
CH : Chinese model
E1 : 220 VAC area in E model
EE : East European model
JE : Tourist model
• Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when order-
ing these items.
• SEMICONDUCTORS
In each case, u: µ, for example:
uA. . : µA. . uPA. . : µPA. .
uPB. . : µPB. . uPC. . : µPC. .
uPD. . : µPD. .
• CAPACITORS
uF: µF
• COILS
uH: µH
The components identified by
mark 0or dotted line with mark
0are critical for safety.
Replace only with part number
specified.
When indicating parts by reference
number, please include the board.
