Ashley's simple solution works! ===== I guess that the complex metal sandwich of the connector assembly can become permanently distorted or misaligned under proper direction force and this means the pins are not making good contact any more so by adding slack to the socket housing the cable plug aligns it properly upon insertion ===== My opinion is that this is another (understandable in the long term) design shortcoming by Apple but I guess that many people must have paid good $$ out of warranty for such repairs because Apple is not as perfect as it wants as to believe (and pay) or admit themselves. ===== Anybody knows what an Apple Genius does on this occasion? Says "pay $$ for repair" or "wait 10 mins for the tech guy to fix it"? I guess the "proper" solution is a not cheap whole integrated ribbon/socket replacement.
