After replacing a screen and power button on one of our iPhone 5C’s, the home button has become completely unresponsive. We have tested the buttons prongs and they don’t seem to trigger the press, we even replaced the prongs with a new lightning connector assembly and still the prongs don’t trigger the home button. We believe that somewhere before the prongs has gone wrong and is causing the problem however we don’t know where that could be?
Any ideas or advice would be greatly appreciated! Thanks
There’s nothing else between logic board and the two home buttom prongs on the dock to try, except the dock socket on the board and relevant pins. A board view software, schematics and microsoldering tools and skills seem would be needed to fix your issue.
