How can I fix my screen that shows only black?

My phone fall and than showd me pink lines and than it shows only black.

The touchscreen is working I can hear it, I open it hear the sound, it charges and the LED is working when it charges. But the display screen shows only black.

I also called to my phone from other phone, it doesnt even ring to me. And my glass screen broke like 4 months ago but I dont think its relevant for it because it worked fine with the broken glass.

can u help me with fixing the both screens ?
