I left the camera for about an hour to cool down with the batteries out and when I turned it back on everything went back to normal. Hope this helps anyone else in the future.

I've just had the same problem today and I noticed that the camera on the left hand side was a bit warm. I left the camera for about an hour to cool down with the batteries out and when I turned it back on everything went back to normal. Hope this helps anyone else in the future.
