Chosen Solution
Dropped my phone on the floor and then a few minutes later numerous white and black lines appeared on my screen. One side of the phone works but the other side seems to be completely dead! Please leave any possible solutions!
When you dropped it the lcd most likely broke I would recommend taking it to a phone repair shop
You said that the symptoms started a few minutes after you dropped it, I don’t think that the LCD is cracked. Maybe the LCD connector got partially disconnected. On step 16, re-seat the connectors. Link: iPhone 5c LCD and Digitizer Replacement
