After replacing the USB charging port, the phone turns on and has sound. But the display no longer works. I did disconnect the display assembly using a metal tool and I think I disconnected a few connections to the display using the same metal tool but I am not sure if this is what has prevented it from working.
Please help as this is my girlfriends phone…
Thanks.
Added (1). Also, if it's relevant: the phone is the GT-I9505 version.
Added (2). I have put all of the connections back in place and everything is where it was but screen is just black.
