Screen not responding after new screen replacement

My screen has been working fine for the year I had it then the other couple days I've noticed white lines on my screen but it still worked fine just yesterday it started acting buggy and slow and uunresponsive so I took it apart and reseated the digitizer without hard pressure at all and then it just continued to have crazy colorered lines sometimes the screen was completely black yes I disconnected the battery every time but I just put my new screen in and no lines but the first time the touch screen was barely responsive it moved one notification but barely but it just isn't responding. Also I connected the home button and it isn't working either. I need help I don't think I damaged anything
