Why is my iPhone not turning on? Changed lcd/display now not working!
Hi! I bought a iphone 32gb 3gs on ebay that had a cracked lcd and glass. I replaced both with another lcd/display unit (all I had to do was detach the three cables and put the other ones back on). I attached the cables and popped it back into place but now its not turning on at all! I put the broken digitizer/glass/lcd unit in another iphone and it still worked. I also put the replacement in the other iphone 3gs and that worked as well so I know that both digitizer/glass/lcd units work (even though one has a cracked lcd and glass).
Looked in the headphone jack and it shows water damage (red/pinkish strip/indicator). Imagine that. I just don't understand how it was working perfectly/fine before and simply swapping the display unit out would make it stop working though.
Any suggestions? Already tried removing the logic board and reattached it btw.
I tried charging it with the standard wall/usb cord unit for a few hours and when I came back the phone was really warm. I've charged the other 3gs many time through my computer so I'm not sure if that's a sign of a bad battery maybe?
Is this a good question?
