Black Screen on cold boot
When booting up, laptop will go from standard grey startup screen to black screen, just when it's about to load the login screen.
- External monitor works.
- In target mode screen works
- If I leave it in target mode overnight, so fans are spinning, laptop gets warm, screen eventually comes back.
So is this backlight problem or motherboard problem? Apple Hardware Test reports everything is just fine?
