I have a brand new mac mini 2012 with 16gigs of ram, i7 and 256gb sad crucial m4. When he falls to sleep, he lights up 2, 3 times slowly before it lights down definitely. Then, my tv monitor appears NO SIGNAL on the screen. And the only thing i can do to it wake up, is to unplug the power cable and connect it again. I have researched about it, but it seems that no one know what is that.. A lot of solutions and problems with no effect on me. Has anyone any idea what might be!? Thanks m8s!
