Screen turns black when hitting the table as a curtain

So I replaced my cracked screen, and now sometimes half of my screen tunes gray when I “wake “ the phone, to enter my password, and after some seconds, it is normal, or I press the power button 2 times and it tunes normal.

But now I just put my phone on the table a little hard, and the screen turned black, from top and from the bottom in to the middle as it was a curtain.

What to do ?

Check the display connectors. Sounds like a bad connection or failing backlight. Did you disconnect the battery when you did the repair?
