I have an iPhone 4s .its screen is not working .when I plugged for charging it make sounds but never gets on .what do I do?
Hi, Usually your iPhone making a sound but showing no image usually means a bad LCD. But before you go replacing your screen, try rebooting your phone by holding the lock button and home button for over 12 seconds, if you see the Apple logo, then great! If not, you should replace your screen, there are plenty of guides on YouTube and a great guide on ifixit itself, but if you don’t feel that you are confident enough, take it to a professional. :-)
Sounds like the screen is faulty, check if a computer will recognize the phone and if it does, then replace the screen.
