Hi @salmonjapan ,I connect to mac,nothing happened.I think maybe the new screen is the problem ,so i disconnect screen from iPhone.Then i found Itunes jump a messagebox saying" Itunes cannot connect to iphone,because it's locked by password,Please enter password...." .So iphone is good .

I disconnect battery cable to power off,and connect again , iphone make a sound represent it is charging.

so maybe new screen is bad.....

Sounds like your computer sees you're phone as being on and the screen is defect. Get a new screen or try with your old screen if the LCD is still working to confirm that to be the case.
