How do I fix my LCD screen?
Originally, just while using my MacBook as usual, the screen just all of a sudden went completely black (with a thin white line at the bottom). The Apple store said that we would have to replace the LCD/LED screen.
Thus, I had a family member replace the screen. So now, the screen lights up, but it is completely white and does not display the actual screen.
The computer itself still works completely fine and everything is visible and workable when plugged into another monitor.
Any idea on how to fix this?

It also has this odd little red arrow?
Thanks for any help!
