Dead spot on upper left corner
I have been working on an iPad Mini which is giving me headache. I replaced the digitiser and experienced the screen going absolutely crazy when laid flat on the frame.
Got the solution for that by searching here - taping the copper parts on the new digitiser which solved the issue. But then I got a dead spot on the upper left corner instead, approx. 2x2 cm where the digitiser is unresponsive. Tried another digitiser but with the same result - a dead spot the same place.
When removing the digitiser from the frame and holding it up, it seems to work periodically.
I tend to think that there is a hardware error in the iPad but maybe I'm just missing something vital? Any suggestions/advice will be greatly appreciated ..
