Blue line across one edge of iPhone 4S
Hello, i'm a little stuck at the moment. I recently bought a broken iPhone, the screen was cracked and the home button wasn't working. I spent about 2-3 hours on it as the home button was proving to be tricky! Anyways.. I replaced everything and i thought everything was good, the home button works fine now and the screen functions i.e Touch works well, picture is fine etc.. however there is a faded blue vertical line down the left hand side... Here's a picture:
I'm really not sure what to do. Does anyone have any advice as to what could be the issue?
P.S This was my first attempt at fixing an iPhone!
Thanks in advance
