Touch screen doesn't work,No water damage, No connection problems.
Hi. I have iPad Air 64GB but as I describe this title, touch screen doesn't work.
I mean cannot recognize any touching operation.
I open it but it doesn't have water damage, there are no connection problems. (because screen works well on the other iPad Air)
Strange thing is occasionally it works well for very short time then within 1 min back to initial condition.
How can I fix it? and where I have to change into new parts?
