I dropped my Iphone 5c and the touchscreen won't work, also the screen shows a few white lines. Also a month before that happened my screen was replaced it, because I cracked it.

The screen is probably too damaged again. It sounds to me like you will need to get another replacement. You should also probably invest in a phone case…
