My MacBook Pro has a black screen at startup.
When I turn on my MacBook the Apple startup sound plays, but the screen remains off. However, I found if I close the lid to enter sleep mode, then reopen the laptop, I am able to access the desktop.
Additionally, I cannot connect to external monitors and, occasionally, a white screen appears prompting a reboot while watching VLC or youtube.
Does anyone have an idea which part is causing the issue? I am thinking the dedicated GPU or maybe the entire logic board? I am hoping to fix this at home.
