Screen stays dark after a white flash.BUT I have access through netwok
I have a 2010 27” iMac and every time I turn it on it flashes the screen and stays black.I can access it through a network using screen share and I can use its camera.I can see its desktop and use it normally but from another macbook. But the screen of this iMac doesn’t show anything.
What might be the problem? is There anything I can do it before take it to assistance?
thank you very much!
