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
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
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.
