vertical lines/touch screen inop

After replacing the battery, which went very well. I reattached the screen, when I powered it up I had vertical lines and one row of white squares (horizontally) across the screen. When I tried the touch ID it wouldn’t work but the screen changed and asked for my password, but the touch screen won’t do anything when I touch it. I have taken it back apart 4-5 times making sure all the connectors are snapped in place, but all it has done is gotten worse, with no picture being displayed just the lines and squares. Do I need to try replacing the LCD?
