So my iPhone 5 has had green lines on it and I’m wondering if its the replacement screens or the phone connectors. i also had problems with other screens could the connectors be worn out on it.
Usually the screen connectors on the board get damaged if not plugged in properly. Otherwise it would be defective screens (either they come faulty or the ribbon cable from the screen gets damaged from bending). I have not heard of the connectors getting worn out on iPhones, AFAIK they end up looking worn when they are not taken care of.
