Phone fell face down, screen is black but glass is ok

Hello, my Mi9 fell face down, the screen immediately got green. Not is black with some white strips flashs when I pressed). The phone is intact (can’t see any sign of broken glass or scratch or anything like that).

The digitizer looks ok (at least the phone vibrates when I use the fingerprint sensor and the screen blinks when I press.

Tried a hard reset with no sucess. Now I’m waiting for a full discharge to try to ressurect but my hopes isn’t high. Is there anything else that I should try before I buy an LCD replacement?

Thanks! Best regards
