I had a white screen issue with my MacBook replaced the LCD cable. I still got white screen problem after replacing the LCD cable - MacBook do work on a external monitor. Anyone have idea what to do about it? Should I do something actively to activate the new cable for some reason it don’t work?
Given the fact the external display is working, and replacing the cable didn’t alter anything tells us the internal display logic its self is bad. Just like the MacBook Pro Apple moved the T-CON logic to sit within the main case vs the display lid. This puts it at risk either overheating or the massive number of cables now required
