w580i screen
 

recieved a phone for repair to change the keypad membrane on the se w580i. As you will know, the side 2 keys for forward and back, the camera and earpiece are all connected to this. Everything dismantled, built it all back up to how it was before, problem is now my screen will not turn on, although the phone clearly works as I managed to get the demo to play.


Any solutions?
