I have had my Mac Mini since late 2008 and it has been connected to my LCD HDTV with DVI to HDMI ever since. The other day my 2 year old daughter was hitting keys on the keyboard and then the screen went blank. I took it to the apple store and they plugged it into their DVI to VGA connector cause they didnt have a display with an hdmi port and it worked fine. So i bought a new dvi to hdmi cord thinking that was the problem, and when I got home it still didn't work. I went back to the store and they didn't know what was wrong with it. I have to get on my computer for work as soon as possible. I have tried everything from resetting the PRAM to logging in blind with 'voice command' and changing the display resolutions, nothing is working. I even tried my other hdtv, same thing...no signal. Why would this stop working all of the sudden? What can i do to fix this?
