Did you install the old screen or did a service shop install the old screen?


Either way, a genuine new replacement screen was not installed. An old screen was installed.


The message about an Unknown Part will continue to appear unless you can convince an authorized Apple service center to install a new genuine screen.


I would be amazed if you could do this.
