Try doing a power reset:
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.

If your camera is experiencing an issue and the issue is not resolved by performing the appropriate reset procedure above, then service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.

Hey jshaff, try taking off the detachable front, and you will see a reset button, press and hold in for 10 secs, this should solve your problem. if it doesn't work first time keep trying. you must have power to the head unit for this to work. you will hear the cd make a noise and that should be that, try and let me know.

Good day.
Please check with the channel buttons of your unit. They replace the power buttons functions.
