Screen keeps going black after denting the back

Hello. I recently made a dent in the back of my iPad pro 12.9' 3rd Generation. Since then, the screen would turn black after a few minutes of use, only to work agin a few hours later. I was wondering if this sounded like an issue worth trying to repair. Many thanks.

PS Initially, pressing the volume up button, volume down button and power button briefly in sequence would turn the screen back on, but this doesn't work anymore.
