Touchscreen nonresponsive. Related to home button flex cable?
Hello, I am working on a 5s for a friend and am kind of stuck. I received a beautiful 5s with no visual damage. powers on fine. just the touch screen is nonresponsive. Nothing at all. I opened the phone and noticed the home button flex cable cover (little metal clip) was missing. So I continued. I removed the screen and inspected. I see no signs of liquid damage and other than the clip missing everything else looks fine. I asked my friend to explain what happened and he said it was working fine he keeps it in a good case and it just stopped working. He said he didn't drop it or anything. He had a local "fix it shop" look at it and they put a new lcd/digi on and still didn't work. I am assuming they lost that clip for me :)
So I ordered a new lcd/digi and put it on. I noticed that the touchscreen works perfect until I attach the home button flex cable. As soon as home button is attached, it goes nonresponsive again. I unplug the home button and it works again.
Is that little clip a grounding point or something??
I have anothe home button from a 5s that I will try in there tonight (I realise the touch ID will not function) but if it brings the digitizer back, the phone won't be a total brick.
Any help is greatly appreciated!!
Ok cool. I will try that when I get home.
Thanks for your help
Anyone have any ideas?
Thanks in advance
Ok, I used a home button I had from a previous 5s repair and it seems to work fine. (With no Touch ID of course)
I guess it was something with the original home button causing the digi to stop working.
Wish I could pin point the issue. I hate to just throw parts at things but at least the phone is working.
Sorry to be a pain haha
I get home from work and check the phone. It is non responsive again.
I don't know what to look at now.
Is this a good question?
