Broken backlight from logic board cause
During a screen repair I didnt disconnect the battery and when i connected the home button connector to the logic board a small amount of smoke came out. I had the board microsoldered and repaired but I am wondering now what the cause was? Was the replacement screen faulty or was it just because the battery wasnt disconnected as id like to know if i could still use the replacement screen or if it needs binned.
Is this a good question?
