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?

you haven't moved the motherboard at all?

why don't you take some photo's of the display back and the inside of this phone then we might be able to see what is causing this. take your photo (jpeg/pdf etc)then click on the little orange box in the corner of the screen "images" and upload. (sorry if you knew that but I think it's ridiculously easy to not see it!)

Do you know the health of this iPhone before the repair? I have never heard of this reaction to a 3G digitizer, is the digitizer definitely 3GS. Repair persons have described strange shorts with damaged #3. A connector #4 issue does not make sense here, but since nothing makes sense, make sure connector #4 is seated correctly.
