IPad screen issue

Hi

my iPad Pro just making sound whenever I’m put it on charging but screen doesn’t showing anything completely blank, not even making any other sound. Whenever, I’m unlock my iPhone it’s showing me message for iPad recovery mode, when I press continue it’s asking me code displaying on iPad which I can’t give because screen not showing anything. I tried the restart/reboot it by pressing volume and power buttons but nothing seems to be working. Also, I tried to connect it with my PC (apple devices,iTunes) using usb cable but nothing works. Can you tell me how can I fix my ipad
