MacBook
boots to white screen with chime, nothing else. External monitor shows login screen and works perfectly. Replacing the LCD flat cable does not change the symptoms at all.

Which one would you bet is faulty? Screen, logic board or this mysterious board between logic board and screen?
 
Usually if external screen works but internal doesn’t I jump to conclusion of a faulty screen but I’ve heard theories that the video chips on these MacBook’s can have a specific problem where external screen works and internal doesn’t. Sounds weird to me but at this point I’m clueless and I need advice from technicians who are experienced with this model which is a lesserless common product.
