Google Pixel 6a screen not displaying

Purchased a Google Pixel 6a off Swappa.com for my son. Worked fine from the startup. About a week in, the screen locked up, it wouldn't respond to anything, you could see it, but would't repond to touches. A hard reset it. Now a week later, my son was at work, dropped the phone. Was able to use it and checked his school grades/assignments. Later the screen would not display any longer. Tried to do a hard reset multiple times, but the screen isn't displaying anything.

What possilbe fix could be done for this phone, I'm looking to doing a fix myself as long as the price doesn't go very high.
