Hello and thank you for your question, I look forward to assisting you today. There should be an error code following the message, something like E-03. Can you check that for me and let me know please?
This is a common error and thought to be a faulty connection on the main circuit board. You can try removing the battery for an extended period of time to see if that resolves the issue. The recommended time is 24 hours. If that doesn't work, try firmly tapping on the side of the camera several times with the palm of your hand. That has been know to resolve the error, at least temporarily.
