Hi there and welcome
Can you remove the battery please then hold the shutter button down for 60 seconds then release.
Wait 5 minutes, put the battery back in and try to turn it on.
Tell me please if it now operates correctly
I would like you please to do a reset of the camera
To do this, Press and hold ISO and WB buttons for two seconds to reset the camera to default settings.
Then tell me how it operates please
