[Q] Phone won't charge after replacing screen

After replacing a broken screen(the phone was working fine after the screen was broken), I can't get the phone to charge. The phone doesn't work with a cm7 ROM either, after booting it shows android system at the top with a black screen and the notification bar then shuts off. Froyo ROMs work fine but won't charge and the usb connection to computer still works. In about it will show not charging wen it's not plugged in and discharging when it is plugged into ac or usb. With the phone off when I plug it in it shows the red led at the top like its charging for say 5 seconds then it shows a battery with a temp gauge in the middle of it and everything goes black again. I've tried opening it back up and reseating the cables but same thing, also tried two batteries both of which were working fine before replacing the screen, one was the stock battery.

Any ideas?
