So my iPhone 4s screen has just suddenly gone blank. Iv tried charging it and changing the charger. My friend rang the phone it still rung but it didn’t even display a call coming up on the screen.
First try a soft reboot, hold power and home button for about 30 seconds. Occasionally older iPhones can lock up and need to be rebooted. If that doesn’t work most likely will need a new lcd screen.
