Q: help my phone screen is blacken out

Hi 711alex711,

If you are getting nothing but black on your iPhone's display, I would suggest that you troubleshoot using the steps in this article - 

iPhone: Hardware troubleshooting

Specifically -

Display has no backlight or dark screen

 

1. Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
2. Try turning iPhone off and then on again.
3. While connected to the iPhone charger, try to reset the iPhone.
4. If the low-battery screen appears, charge the iPhone.

Thanks for using Apple Support Communities.

Best,

Brett L
