Hi there Ben and welcome
Can you remove the battery and then hold the shutter button down for 60 seconds then release.
Then wait 5 minutes, put the battery back in and tell me if it now functions correctly please.
It is the LCD Screen that has faulted.
A corrupted firmware can cause this. But we have ruled this out by trying to hard restart it.
I am really sorry about this and you are going to have to return the camera to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
