I replaced the screen on my phone and now the phone will power on and show an image randomly and then it will go black again everything works becuase when its on but the screen is black but I still get. Notifications and when I try to hard reset the scree. Flickers a light and then nothing sometimes the screen works for mins sometimes for seconds keep in mind when the iphone screen turned on I was able to call and text
It’s a bad screen, try getting a replacement screen under warranty from where you got it from if possible.
