Attention When Pick-Up Is Exchanged - - JVC XV-S300BK Service Manual

Attention when pick-up is exchanged
1.Flexible wire, pick-up spring, switch actuator,
and lead spring are removed from an old pick-up
(broken the one).
< Guide >
Flexible wire, pick-up spring and switch actuator,
lead spring are removed without each decomposing
while assembled.
2.The above-mentioned parts are installed in a new
pick-up (non-defective article).
3.A flexible wire is inserted in the connector which has
taken side with the pick-up, and solder is put up to short
land part "a" two places on a flexible wire.
4.The electrostatic breakdown protection circuit attached
to the pick-up is cut.
< ATTENTION >
Please cut the electrostatic breakdown protection circuit
attached to the pick-up after solder is put up to two places
on a flexible wire short land part "a" of the insertion of a
flexible wire this time in the connector without fail.
The procedure might be mistaken and if solder has not
surely adhered to two places on a flexible wire short land
part "a", the laser diode in the pick-up be destroyed again.
5.The pick-up is installed in the traverse mechanism.
6.A flexible wire is connected with connector CN101 on the
servo control board by installing the traverse mechanism
in the loading mechanism.
7.Solder in two places on a flexible wire in part "a" is
removed.
< ATTENTION >
Please remove solder in two places in part "a" after
connecting a flexible wire with connector CN101 on
the servo control board without fail this time.
When the procedure is mistaken, the laser diode in
the pick-up might be destroyed.
Please remove solder in two places in part "a" surely.
