Why is my Olympus Tough camera screen displaying 'no connection'?

You are getting this message because either you have water damaged it, or you tried putting a wrong cord into it. Try restarting it and if that doesn't work, try replacing the SD card located on the bottom of the camera. If neither of those work, try taking it to a camera repair shop and see what they think you should do. Hope this helped :)
