IPHONE 4S SCREEN DISPLAY TURNED BLACK

Hi rupinderfromnangal,

To troubleshoot this issue where your display is only showing black, please follow the steps outlined below.

If you see a solid color screen (black, white or blue)

1. Plug in your device to a power source. If you see the low-battery screen when you plug in, let your device charge for at least 10 minutes (20 minutes for iPad) before using it.
2. Reset your device while it's plugged in.
3. If resetting doesn’t fix the issue, restore your device.
4. If you still see the issue after you restore, contact Apple Support.

Cheers,
