Home button not working even after charging dock replaced, but charges
I have an iPad 3 WiFi only that came to me originally with a no charge problem. Upon visibly inspecting the charging port, I could see some of the pins were damaged so I ordered some replacement charging dock connector flex cables and thought it was going to be an easy fix. I was wrong.
I took the digitizer and LCD off and removed the original charging dock connector and installed the replacement charging dock connector. I tested to ensure it was charging, and it was. Fixed that problem. But when I loosely assembled everything to test the home button, it doesn't work. So I ensure that the gold contacts on the bottom of the home button bracket are lined up perfectly with the gold pins on the charging dock connector and they are. Still no difference. Home button does nothing when pressed, although it does charge.
So next, I replaced the home button bracket altogether with another I had. No difference.
Next, I swap out the replacement charging dock connector with another new one (I bought 3). No difference.
So next, under magnification, I inspect the pins on the logic board to see if any are damaged. Looks fine to me. I clean them up anyway with some 91% alcohol and try again. No difference.
Beginning to get frustrated, I DFU Mode reset the iPad and tried again. No difference.
What is going on here? All of the charging dock connectors I have tried do charge the iPad, but none of them allow the home button to work. I have swapped the home button bracket that has the physical click-button and gold contacts with another and it didn't fix the problem. The connector on the logic board doesn't appear to be damaged and I ensured it was clean. I DFU Mode reset the iPad. Nothing has worked and I am at a loss.
Where do I go from here? Thank you for any help.
Is this a good question?
