iPhone 5s touch screen unresponsive
Hello FIXIT'S
This Is the First time i've had a problem like this before, wondering if anyone could give us a hand and enlighten me.
I currently have in front of me an IPhone 5s, it had been dropped. (NOT IN WATER)
So long story short, the phone touch screen is not longer working.
I have changed many screens to the same phone / logic board
I have also swapped the logic board into many other working phones also.
But still no touch response?
The problem is clearly with the logic board,
but what is the reason?
what could the problem be down to?
and what location should i be looking in?
Any ideas guys?
P.S
I've also reset phone holding power and home button for 15 seconds etc etc
Much appreciated,
Kyle
Is this a good question?
