Pickup
Head
consists
of
a
laser
diode
that
is
very
susceptible
to
external
static
electrocity.
Although
it
operates
properly
after
replacement,
if
it
was
subject
to
electrostatic
discharge
during
replacement,
its
life
might
be
shortened.
When
replacing,
use
a
conductive
mat,
soldering
iron
with
ground
wire,etc.
to
protect
the

form
damage
