Replaced Charging port now 2 lines on screen.

I replaced my charging port because it was going bad now I have 2 lines on my screen. The new port is working perfect. I have no idea why there would be lines because the screen cable was never disconnected and just for the hell of it I removed it and put it back on and I have the same issue.

I mean it's not that bad but it is annoying. Right through the middle and down to the bottom left edge. Any ideas?
