    Based on the AHT result, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

    Basically, you need to back up all your data quickly.

    Click the magnifying glass at the top right of the screen, type in disk utility, select disk utility, you will see macintosh HD listed on the left hand side, click the option above it, and at the bottom near the right, it will say S.M.A.R.T status: what does it say there? If you can't find it that way, go: apple logo, about this mac, more info, click serial ata on the left, and smart status will be listed in the box on the bottom, just over half way down.

    I have the same problem and have replied in various communities about this issue.  I bought mine in July 2011 and started having the blackout issues just outside of the 1 year warranty.  I can't tell you how upset I am to have spent $1700 on a new computer and I got 1 year's worth of use out of it.  My screen blackout is getting worse and some days I just shut it down and walk away because it's so frustrating.  I keep pushing the issue with Apple and am disappointed that they have not issued a recall.  For a company that touts it's superiority to that of the PC, they are sure letting a lot of users down.  I am a long time Mac user (back to 84)  and supported this company during the early 90's when Apple almost went under.  Now I have a problem and they can't step up to the plate and fix it.  I have one last appointment at an Apple Store on Monday so I'll see how it goes.

    IF YOU ARE HAVING THIS ISSUE, CALL APPLE CARE AND REPORT IT.  THEY NEED TO KNOW THAT IT'S NOT AN ISOLATED INCIDENT.  UNTIL ENOUGH PEOPLE COMPLAIN, IT WON'T GET RESOLVED THROUGH A RECALL.

    I have a slightly over 1 year old iMac 27", bought in June 2013. I started to see the black screen a few months ago. The screen would just go black for a few seconds and then come back by itself, while I am still looking at it with a *** expression on my face. Recently I started noticing that it starts happening more often, this month so far it has happened 4 times! The last black out lasted for about full 10 seconds. It looks like it's getting progressively worse.
