I can help you with that. Here are some steps you can follow to fix your iPhone screen:
1. Restart your iPhone.
2. Clean your screen and make sure it is free of any debris or water.
3. Disconnect any Lightning or USB-C accessories.
4. If your screen works after removing an accessory, try using a different cable, charger, or power source.
5. If your screen still doesn't work, you can try resetting your iPhone to its factory settings.
6. If none of these work, then you can at least be confident you've tried everything you can before you reach out to Apple for professional help .
I hope this helps! Let me know if you have any other questions or concerns.
