That's tricky. You may have damaged more than just the LCD. Unfortunately the best way to diagnose is to insert a working LCD and see if that solves your issue. You've done a good job trying a variety of things to fix the issue, but '''It's definitely hardware related.''' If you post a clear close-up photo of the ZIF connector where the cable attaches to the logic board, then I may be able to tell you if I see any visible signs of damage.
