Screen is black but phone is on?

[Android Central Question]

The problem is that the LG G4 buttons light up like normal, but the screen remains black and nothing is showing up, the phone is still working and if I take the battery out then press the power button, the screen lights up with the starting and then goes to lock screen, I can see the camera swipe move about three times before my phone freezing then fading off. Notifications go off and my notification LED light is blinking when I get a text.
