Screen Blank... Sort of.

[Autrei]

Hello, I have a old Galaxy s4 that I use as a gaming/music device, I recently put lollipop on it, a bit ago I dropped it from about 3 feet (Unintentionly) and it fell on hard woods (Flat face down) the screen will only show green lines, or be completely blank, it has functioning sound and I was able to turn on the flashlight (By randomly tapping) I was wondering what I could do to fix it, the screen was already cracked but it worked fine, I checked the display cord thing inside the phone but it didnt help. Thank you.

Welcome to Android Central! There are probably quite a few DIY videos on YouTube on how to replace the screen on an S4. If you don't want to try it yourself, bring it to a repair shop.
