Screen stays black on startup
I have read lot's of threads on this site about this problem. I didn't find the solution to my specific situation.
At first this problem was random. Now it's consistent so I can't boot up. At first I thought that this was a software issue so I did a clean install of Sierra.
Problem:
- Chime sounds on startup
- Screen stays black
I have tried resetting the PRAM. This seemed to help a few times.
Diagnostic leds 1, 2 and 3 (left-to-right) light up on boot. Number 4 doesn't light up.
Ist dies eine gute Frage?
