Hat geantwortet auf: How do I fix a broken ribbon cable?Hi, I have replaced many iPhone 6 screens and cables for that matter I have a friend who is clumsy with phones and so it makes for a great learning tool. First of all behind the number cables there are some items that need to be transplanted from the old to the new screen like the home button cable for instance as well as others. The touchscreen problem may have something to do with the digitizer cable but that generally comes on the replacement. If they are all there id try running an alcohol pad on the contacts to make sure no oil is on them as that can make them not work. If you have to change the cable you're in the right spot the guides here on ifixit are amazing and I couldn't do the repairs I've done without them !
