Correction

Inspect the lens block focus reset sensor (Note) when focusing is
performed when the touch panel is operated in the focus manual
mode and the focus motor drive circuit (Note) when the focusing
is not performed.

Inspect the lens block zoom reset sensor (Note) when zooming is
performed when the zoom switch is operated and the zoom motor
drive circuit (Note) when zooming is not performed.

Inspect the flexible board for breakage or loose connection.
If not faulty, inspect the focus and zoom motor drive circuit (Note).

Inspect pitch angular velocity sensor (SE601 of SI-042 board)
peripheral circuits.

Inspect yaw angular velocity sensor (SE602 of SI-042 board)
peripheral circuits.
