Touch IC iPhone 6 PLus - C2414
I have a question plz only for general knowledge because I m learning about smd board repairing.
I have an iPhone 6 plus.
If I check the voltage on c2414 it will be 5 volt right?
My question is : the voltage wil be same with or without lcd connector attached? (obviously iPhone must be turn on :) )
I m asking because I have an iPhone 6 plus with no touch responding.
I check the voltage on c2414 and it was ZERO.
I reball u2402 and touch screen begin to function perfectly, but the voltage on c2414 is zero.
So I m confuse, I m not understanding which is the way for understand where is the fault, before recall or changing ic’s.
Thanks a lot for attention and forgive for bad English :)
Is this a good question?
