no power to any connector
hi there I have a strange case here !
my iphone was working great but there was a problem with the dock connector so I bought one from I fixit and changed it but after that , there is no power reaching for any of the connectors ! ,what I mean when I plug a charged battery the phone powers on but no screen of curse and no sound and no power button or any other button working !
but when I try to call it the other phone used to call shows me that's it is ringing and when I unplug the battery it hangs up so it is working but with none of the connectors inside working !!!
what is the problem ?
ps. I accidently hit the motherboard with a screw driver near the battery connector by mistake !
please help .
