TouchScreen not working randomly
I have a customer with an situation that i never see happen.
My customer have is TouchScreen that randomly works and major times dont work.
It dont seems to have damages on connector but i will have to check better on microscope.
I changed the battery for a new one and same problem
Changed the LCD for another and same problem
Changed the MotherBoard to another case and same problem
So the problem is the motherboard. I thinking on Touch IC but have ever happen to some one the touch work randomly?????
Is this a good question?
