Hey there! With all the displays working fine for a time, it seems unlikely that you've run into four with the same issue in a row. It's more likely a board-level issue, most likely having to do with bad filtration. You might have a faulty capacitor or blown the filtration leading to the digitizer. I'm not sure that this answer is particularly helpful, because repairing that is, at the very least, beyond my knowledge. I would try a new [product|IF126-023-8|logic board], and see if that resolves the issue. I might also suggest a new[product|IF126-001|display], because the ones you have may well be damaged by the previous board. Best of luck on your repairs!
