TABLE OF CONTENTS
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270˚C during
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.

ELECTRICAL PARTS LIST
Ref. No. Part No. Description Remark Ref. No. Part No. Description Remark
MAIN
NOTE:
• 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 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
• Items marked “*” are not stocked since
they are seldom required for routine service.
Some delay should be anticipated
when ordering 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
When indicating parts by reference
number, please include the board.
• Abbreviation
CND : Canadian model
EE : East European model
CH : Chinese model
E : Indication of country of origin
1E : No indication of country of origin
The components identified by
mark !or dotted line with mark.
!are critical for safety.
Replace only with part number
specified.
Les composants identifiés par une
marque !sont critiques pour
la sécurité.
