Resposta para "Why my monitor remains black?"Mine did exactly that. A new cmos battery fixed it.
Resposta para "Is this what a damaged FL11 looks like on a iPhone SE?"Yes, the photo shows empty pads where at least two of the four components were pried off the board. I can see at least one of these parts sitting nearby. You must remove these loose, damaged components and solder new parts on the board. Loose parts can bounce around inside your phone and cause more damage.
