Flexible Circuit Board Repairing
¥ Keep the temperature of the soldering iron around 270 ûC 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.
SECTION 1
SERVICING NOTES
In this set, the S102 (POWER) detects REC/PLAYBACK on.
It is mounted on the MAIN board, and therefore the REC/PLAY-
BACK on cannot be detected with the MAIN board removed.
When making an operation check and voltage check of mechani-
cal deck with the MAIN board removed, fix the S102 at turn on.
