I need a logic diagram for my 13" MacBook Pro i7 A1278 system

I can only see the screen with focused light aimed at it.

I need the logic diagram to identify which component that gives light to the display. I understand that it is a component that dims the backlight

661-6079 Apple Macbook Pro Late 2011 i7-2620M 2.7Ghz Laptop Motherboard A1278, MC724LL / A, EMC 2419, 21PGJMB00N0, 21PGJMB0110, 21PGJMB0150, 820-2936 agradecere-A

Who can tell me how to recognize or identify that component

Sorry my English is bad

Thanks to machead3 which answered my previous question

Trying to follow the thread of questions, but I was unable to cross-examine why again.

roberto arismendi , there are a few components. Start with the LVDS connector, the fuse as well as the LED driver. It all will depend on what you have checked as well as your skills and your tools.
