MacBook Pro 15” Retina 2012 Black screen
since couple of days I’m having issues with the display of my MacBook.
Yesterday the boot up Apple screen was showing the loading of the os, but when it reached the login screen the screen was getting black. Even though the backlight keyboard was showing that the os was starting correctly.
Since today I only get a black screen, even tough the startup sound is correct and the backlight keyboard is working correctly.
I have tried to:
-enter safe mode
-reset smc and nvram
-reboot the system with P+R+command+option
-reboot several time
-try to enter recovery mode
-try to attach the hdmi to an external source (to be sure that the problem was not the screen)
My fear is that either the discrete or the integrate graphic card are not working correctly anymore, but in order to force the usage of one of the two I need to access macOS.
If this is the case I will have have to substitute the logic board. Do you have any suggestion to better deep these analysis?
If the logic board will have to be substituted, what do you suggest me to do? Try by myself, take it to an Icenter or buy a brand new one?
I just noticed this guide:
How can I be sure that this might be the issue? Is there any check or analysis to be conducted? And how can exclude that is not the logic board?
Questa è una buona domanda?
