First, make sure that you do not have the camera set to "macro" mode.
Next....make sure that you have a fully charged battery.


That camera has several manual controls.
It is possible that you have set something wrong inadvertently.

It is usually somewhere in one of the menus.

Check you camera User Manual and look for a reset feature.
It is used to change all your settings back to factory specifications.
