I know for a fact this phone is turning on because after I charged it and held down the power button, the home button started working. This means the phone is working but the screen is not? Is this just a screen problem and it needs to be replaced or bigger?
Have you tried reseating the display cables at all? There is a strong chance that they could of become loose enough to stop the screen from working. Otherwise if that doesn’t work I would recommend replacing the screen and that should fix your issue
