Make data on A page and D page correct value.

Inspect the lens block focus MR sensor (Pin ql, wa of CN3801 of
LD-176 board) when focusing is performed when the focus buttons
of the touch panel are pressed in the focus manual mode, and the
focus motor drive circuit (IC3801 of LD-176 board) when the
focusing is not performed.

Inspect the lens block zoom MR sensor (Pin qh, qk of CN3801 of
LD-176 board) when zooming is performed when the zoom lever
is operated, and the zoom motor drive circuit (IC3801 of LD-176
board) when zooming is not performed.

Check whether the flexible board of the lens is broken, and check
whether it is inserted imperfectly. If there is no problem in the
flexible board, inspect the focus/zoom motor drive circuit (IC3801
of LD-176 board).

Inspect pitch angular velocity sensor (SE8201 of IR-055 board)
peripheral circuits.

Inspect yaw angular velocity sensor (SE8202 of IR-055 board)
peripheral circuits.

Checking or replacement of the flash unit.
