my iphone was dropped and the screen became unresponsive and had lines in it. i unplugged in the batt from inside the phone, took off the screen check to see if any of the bands were bent and placed everything back. now it wont turn back on. i have an older iphone6 and i put my unresponsive screen onto the older iphone. the screen turns on fine. then i plugged the old iphone bat into the iphone that isnt working and it still wont turn on. any suggestions? also when i plug it into the computer it wont recognize the phone.
It seems like the screen is good but the phone isn’t. You may try to switch battery or even better the logic board from one phone to the other since you have two of a kind, to make sure you haven’t got some shorted components preventing the phone booting. If that’s unsuccessful and you have a logic board fault, you will need a microsoldering pro to take care of it. Since you talk about iphone 6 but you’ve selected a 6s as reference I won’t link you a logic board replacement guide, but you can easily find it yourself, both are available on ifixit.
