What is causing this screen issue? No touch/screen (Pictures provided)

I believe it to be the middle connector port but I am not entirely sure. The phone had a IC chip repaired a while back so I am pretty sure that isn’t the problem. The phone was okay at first but I woke up to some vertical lines (but still 95% viewable) on the screen and a horizontal dead spot where you couldn’t touch near the middle of screen (the spot had more lines than usual). This continued for like a week and I replaced the screen and the second picture shows what happened next. I swapped back to original screen and same thing.

I don’t want to waste my time and money sending it to someone to microsolder the wrong connector back on so I would like another opinion on this. Thanks for any help!
