My iphone 6's screen freezes and fades out with multi color lines. What can i do to fix it?

Hey radovich24,

It sounds like your iPhone 6 boots okay but later it freezes and fades to multiple colored lines on the screen.

There's a section in this article for "If you see lines, missing sections, discoloration, or poor image quality" in this article:

Get help with the screen on your iPhone, iPad, or iPod touch - Apple Support

If you see lines, missing sections, discoloration, or poor image quality

1. Try to restart your device. If you can't restart, force restart your device.
2. If this doesn't work, restore your device.
3. If you still see the issue after you restore, contact Apple Support.

Thank you for using Apple Support Communities.
