Chosen Solution
OK so I just replaced the battery of my iPhone 5s with the battery I ordered off this site and followed their given guide. Unfortunately after I finished changing the battery and putting everything back like it was before hand I noticed that the screen is only black. I put it on the charger and the phone generates some heat and also when plugged to my computer is activates the iTunes which shows that the phone is on but the screen is just black. Can anyone tell me what went wrong while I was working on the Iphone and is there any possible solutions?
Double check your connections. It’s very possible you don’t have the LCD cable in there correctly. It’s also possible you damaged it. It’s likely getting hot because the digitizer cable is working, but the LCD isn’t. Circuits not complete, and the logic board is getting cranky. +1 for doing this yourself. It’s not the end of the world if the display is broken, things happen when you do anything the first time
Well you could try taking it apart again and putting it back together.
