Why does my display screen go black at certain times?

Why does my display screen go black at certain times?

I’ve had my camera for a few months now and I LOVE it! had no problems until recently. I was deleting multiple shots from my camera and suddenly the display screen went blank. Then it wouldn’t shut off. I had to take the batteries out and put them back in again. It does this now when I want to view the pictures I’ve took or if I hit the trash button. Please help!!!
