Thanks for your reply
even though the screw assembly has broken away from the mother board, this screw assembly was soldered in would not damage the back light or power to the phone ?
Bottom left 1.2 screw assembly broke off from the mother board and now my phone will not power up . Can there be another reason for the phone not switching on . How important to the function of the phone is the broken screw assembly ?
