Touch problems (certain keyboard keys not working)
I have an iPhone 5c that has had the screen replaced a number of times.
I now have a vertical line on the touch screen that is unresponsive.
When using the touch keyboard the n , j and u keys do not operate (these are all roughly in the same vertical area).
I have tried the same screen/digitiser on another phone and it works fine.
I have also tried a number of screens on the problem phone and always find the same area of the screen does not respond to touch.
I suspect one of the pins on the digitiser connector is damaged though I can't see any obvious damage.
Is there anything else that may cause this problem or will the logic board need to be repaired/replaced?
Es esta una buena pregunta?
