I assume that it does not work and only displays the message.
I would first recharge the battery.
If the camera is off and in recording mode, the lens should extend when you turn-on the camera.
Observe as you turn the camera-on and see if the lens tries to extend.
If the camera has been dropped, the lens is probably jammed.
Not something you can fix yourself.
I suggest you phone Panasonic Service and ask them what the message is trying to tell you.

There is a massage on display: "Please turn camera off and then turn on again". Is that any ways to fix it? Please - tell me how .....
