is rotated in the focus manual mode and the focus motor drive circuit
(IC1553 of VC-304 board) when the focusing is not performed.

Inspect the lens block zoom reset sensor (Pin qg  of CN1551 of
VC-304 board) when zooming is performed when the zoom switch
is operated and the zoom motor drive circuit (IC1553 of VC-304
board) when zooming is not performed.

Inspect pitch angular velocity sensor (SE751 of SI-035 board)
peripheral circuits. *1
