iMac 2011: Black screen after ~10min of usage.
The main screen of my iMac 27" (2011) goes black after ~5/10min of usage!
The system is running and I can still work with my two external monitors.
When I’m pressing shift + ctrl + eject (logout) and space to wake it up, the screen turn on again!
- I installed fan control and all the temperature sensor are below 30° (86°F)
- Fan don’t spin on high
- It’s not the graphics card, external monitors are still working.
- By holding a flashlight up the screen I can see my desktop Icons.
- In Safe Mode the problem persists.
Could the problem come from the Inverter or is it just a software problem?
Any advice would be appreciated.
Ist dies eine gute Frage?
