iPhone 6, 6 Plus Unresponsive Touch Screen - GSM-Forum

Dear Members,

First and foremost thanks for allowing me to join your forums, you guys are an invaluable resource to newbie techs such as myself. I have the following issues I wanted advice on. I have an iphone 6 that I performed a screen repair on that has touch function issues. At first it was working intermittently and then now not working at all. I have seen many solutions, from retracing under the screws and reheating the IC to 280C. However as I have not seen a solution related specifically to the iphone 6, I thought I would do the safe thing and double check with the experts. Again everything is fine, there is no blue screen, I thought it might be water damage so tried scrubbing the board with alcohol to no avail. I am considering giving the whole thing an ultrasonic bath but please advise so I can take the correct steps. Again thanks to all and you guys are the best!

Hi,
I have customer who brought in a an Iphone 6+. It had a smashed screen and he said at the time by putting pressure on it he could get it to work intermittently even though the screen was smashed. We changed the screen and everthing worked fine. About a week later he brought it back saying still not working. When he placed pressure on it it would work for another while. Because he is a business man he couldn't do without his phone so it was hard to know. Can anybody tell me that really the problem is not the screen but somthing else! Many Thanks in advance.

change touch ic !
common problem on iPhone 6/6+ since the iPhone 6/6+ and the mainboard can a little bit twist and bend and the touch ic is located almost in the middle of the iPhone and therefrom is affected by bending and twist.
