Hello,
Apple has several documents helping you with Face ID.
This document is specific to seeing a 'disabled' Face ID alert, and what to do. --> If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support
If you don't see a 'disabled' message but do have general issues with Face ID not working properly, explore the list of things to try in this document: If Face ID isn't working on your iPhone or iPad Pro - Apple Support
If the first 8 don't solve the issue then use #9, contact Apple.
About the green line, refer to --> iPhone Repair & Service - Apple Support
If your FaceID requires repair then likely it will all be done as one service.
