My screen is not showing anything, even new one.

So i have a Xiaomi redmi 8 pro (i did not found it in list) and its display is not showing anything. It does get notifications so it is working but does not show up anything. So i tried new display but same issue. I tried to leave it on charger, then after charging i turned it on and Xiaomi logo showed up but it did not started. This happened 3 times then nothing.
