Inspect the lens block focus MR sensor (Pin
ql
,
wa
of CN7006 of
NN-001 board) when focusing is performed when the focus ring is
rotated in the focus manual mode and the focus motor drive circuit
(IC7201 of NN-001 board) when the focusing is not performed.

qh
,
qj
of CN7006 of
NN-001 board) when zooming is performed when the zoom switch
is operated and the zoom motor drive circuit (IC7201 of NN-001
board) when zooming is not performed.
