A broken LCD looks like this:

Or vertical lines like this:

MacBook Pro with vertical lines on left side


Sometimes even this:

Black splotches at top of screen due to crack


That one kind of looks like gathering storm clouds against the El Capitan background.

And this one looks like a bullet hole on the MacBook screen. Sometimes that’s what a cracked LCD looks like too.

And, what does a repaired MacBook LCD look like?
