hello. I don't know much at all about computers so could use some help. I am getting no picture from my mac. I have tried hooking it to a different monitor with no luck and have used a different vga cable to connect with no luck so it is something wrong with the computer itself. The computer turns on fine (I can hit the play button on keyboard and get itunes to play music) I have contacted a local repair shop asking for a quote or idea what the issue is, but it is midnight and won't know till tomorrow at earliest. Am sure am going to lose sleep over this so coming here to see if anyone can tell me the likely culprit and how much I should expect to have to pay to fix the issue.
