Replaced digitizer - now phone shorts USB or charger
I just replaced a broken digitizer/screen for a friend on his 3GS and now when I close up shop and try to charge the phone, it shorts out/overloads the charger. On a PC, it pops up that the USB Power has been exceeded, and on a wall charger it goes into overcurrent mode.
This does not occur if I plug the charger in with the screen connected (connectors 1, 2 and 3) but not closed up (screen just hanging there). It seems to be some type of short by the screen assembly. If I hook the top in and leave the bottom open the issue doesn't happen, if I leave the bottom in and the top open, it doesn't happen, but as soon as I fully seat the screen, the power cuts off.
Also, should the battery charge if the screen is completely disconnected? I'd like to get a charge into the thing and then connect the screen and see if it will turn on at all. Even with the screen open and the charger apparently working OK, I cannot get the phone to power up.
Thanks for any insight!
Is this a good question?
