LCD Screen Distorted. Possible bad Connector.

Hi there, I'm having some trouble with my iPhone SE screen. I ordered a replacement LCD and Digitizer and after replacing it I had to remove it again due to digitizer issues, I ended up breaking the screen and ordering another one. However, when I got my second screen after plugging it in I noticed the LCD had a fuzzy display with a line down the middle. I tried the screen in my brother's 5S and it worked perfectly, so I'm thinking it's either the logic board or the connector itsself. Has anyone encountered this problem?
