Try to reset the camera to original settings:
How to reset a Cyber-shot® digital still camera back to original factory settings. Solution
Cyber-shot cameras nowadays have a built-in rechargeable battery for retaining time, date, and other settings. Since the built-in rechargeable battery is not removable, current Cyber-shot camera models can only be returned to the original factory settings by pressing a small RESET button on the camera or by using an Initialize option in the menu.
Older-model Cyber-shot cameras (prior to the year 2000) do not have a built-in rechargeable battery and do not have a RESET button or Initialize option in the menu. These cameras require a manual power reset.
IMPORTANT: To determine whether or not your camera has a RESET button or Initialize option, or for other model-specific information to complete any of the steps in this solution, refer to the operating instructions supplied with the product. Manuals are available online in the Manuals/Specs/Warranty section of the Sony® eSupport Web site.
Follow the appropriate procedure below for your camera.
Using an Initialize option in the menu
Since Cyber-shot cameras have different menu system layouts, refer to the instruction manual specific for your camera model.
Using a RESET button

1. Locate the RESET button on the camera.
2. Use a pointed object (like a ballpoint pen) to press and hold the RESET button for 2-3 seconds.
3. After 2-3 seconds has elapsed, release the RESET button.

Performing a manual power reset

1. Turn off the camera.
2. Remove the battery pack.
3. Remove the button-sized lithium battery.
4. Allow the camera to remain without power for 30 seconds.
5. Reinsert the button-sized lithium battery.
6. Reinsert the battery pack.
7. Turn on the camera.
