    It was the Amsterdam store.

     

    Not sure what will happen next - will give it a couple of days and see what they say

     

    But I suspect they will still blame my TV

     

    Anyway - going to watch a movie now on my old mac mini connected to the same TV that they think is faulty ;-)

    Lol, I'm stuck for what to do.

     

    I can pick up a 2011 mini and save a few quid, but lose the quad core. I am ringing them tomorrow and I want them to send me a displayport > dvi-d adapter and possibly a dvi lead free of charge, then I can test with that. It's the least they can do. They've already offered me a refund but that doesn't help a great deal, I bought this one for the better processor. Plus £60 on RAM wasted if I don't get another one!

     

    Sam.

    I bought a minidisplayport/thunderbolt to DVI adapter while I was there and there has been no blinking or snow since.

    Jenny do you have a part number? Was it one of these?

    Somewhat hdmi related, has anyone ran into an issue where they can't adjust the sound?

    HDMI does carry sound but ordinarily the problem is gremlins in the Sound section of System Preferences. Go to System Preferences > Sound > Output Tab and make sure that it's correctly selected. You'll see under the heading of "Type" where it will say HDMI. Also make sure the volume (at the bottom) is set correctly and that Mute is UNchecked.

     

    Have you checked those settings to make sure that they weren't somehow changed?

        After reading stuff about Mountain Lion in this and one other thread, Iam staying as far away from that as long as I can!! 

    I don't think it's a Mountain Lion issue as much as a particular update for Mountain Lion (10.8.2) which only effects 2012 Mac Minis. I have the same unit that you have and 10.8.2 works flawlessly. You can alsways do a full backup of your present system, take Mountain Lion for a test drive, and if it doesn't work for you simply reinstall your backup.

    And that's a big part of the problem.  If this were a bigger issue, we would have a better idea of the incident rates, and Apple would have no choice but to stop selling the machine until the problem was fixed.  But this issue is something that could affect 100% of the Mac mini shipments, but simply isn't (yet) noticed by some people because it just happens to blink out during the countless half second breaks during the day that they're not watching the screen.

     

    As it stands, whatever the issue is seems to have even Apple saying "We don't see it."  They seem to need to "recapture" machines in order to get a Mac mini with the problem, whereas it seems like just about anyone else can walk into an Apple Store an be guaranteed to get a dud.  People aren't crazy to notice the disparity there.

     

    So it is perfectly valid to wonder what the eventual solution is going to be, and how long it'll take for them to find/admit to the fault.  And it is particularly discouraging to read reports of their "Genius" employees acting like idiots.  The eerie silence is precisely what makes a small problem seem like a big problem.

    This is already a big issue. It effects product being sold worldwide. Apples biggest mistake IMHO was using the HD4000. The HD3000 already had known issues, and PC's using the HD4000 saw those same issue. The HD4000 just doesn't seem to be ready for prime time. I'm sure Intel gave Apple a good deal on the chip, but Apple needs to ask themselves what is their reputation worth? Most people don't care that the problem stems from the Intel chip, they only know that they gave Apple their money and their Apple product doesn't work. I really hope that Apple removes the HD4000 and uses a better chip, and then offer replacements to customers who have this issue with the Intel chip. Wishful thinking

    That's an assumption on your part. What evidence do you have that every single Mac mini is bad? Even if it's 99% that are bad that still leaves an awful lot of machines that are up to spec.

    Not true. Apple wouldn't be working on a fix if they "didn't see it". It is some Apple stores that haven't got the memo yet.

    Have you never had an electronic device go bad? ANY electronic device that is suspected to be bad needs to first be diagnosed. Only then can it be verified and fixed.

    I was wondering about that myself. What about all the Mac minis in the store displays? What about all the magazine reviews about the Mac minis? Every review I've read raves about the mini. However those machines had 10.8.1 which seems to point to a issue with 10.8.2. I have read where people first noticed the problem after they updated to 10.8.2. Could this be why Apple pulled it? That points to a firmware or software update. And what are new minis sold with? 10.8.1 or 10.8.2? If it's 10.8.1 then that might explain why those new machines don't have an issue. Hopefully it all gets sorted soon.

    In all fairness I don't think that was the employees fault, I place blame at whomever didn't update that stores information about the issue. The employee is just going to look up what their database says. If it says no problem then that's what he'll think (and say). However, he could have been a little more professional with what he said to the customer. The 'Internet' remark would have had me ask for the manager immediately.

    Has anyone experienced the black screen lasting about 10 seconds.

    My mac mini has started doing a longer blink about 5 minutes after power up.

    I have the Mid range model.

    We mustn't forget that there will be masses of Mac Mini owners who don't even know that their machine has a fault.

     

    They will be using the TB port either directly or through an adapter to DVI or VGA (have I forgotten anything?). Based on my experience using a FREE adapter TB to DVI, given to me by Apple, they will not discover the problem until eventually (if ever) they decide to use the HDMI port!

    At least I have a brand new unit which came with 10.8.1 and had the problem right out from the box. No 10.8.2 update available at any time.

    Same here, mine had 10.8.1 and had the blink/snow every hour or so.  Updating to 10.8.2 changed nothing for me.  This tread is so long some are forgetting details from a lot of the earleir posts... 32 pages and counting!

    CHECK SMART STRIP. I posted earlier about this issue, but just to join the chorus. This time, I can report that I completely solved the problem as far as my own Mac Mini is concerned. I have everything plugged into a Smart Strip, so that when the computer is switched on or off, so is everything else. This worked fine with my Mac Mini 2010, but the moment I plugged in the 2012, it began to switch off for a second or two and random intervals, turning my monitor black and, more anxiety-provokingly, unmounting any attached disks. Unfortunately, I returned my first 2012 because of the problem, before I noticed that my audio system was also switching off at the same time. That didn't seem right, so I turned my attention from the computer itself to the backup power supply and the Smart Strip, which was causing the problem. I don't know if the Mac Mini 2012 uses less power than 2010 or what. But unplugging everything from the Smart Strip and plugging everything back into a standard power strip totally solved the problem. I hope this helps someone else.

    Well done for coming up with an inventive solution, I am glad that it helps you and I hope that it will help others.

     

    However, this is still only a work-around and presumably your Mini still had the fault, otherwise you wouldn't have done it.

     

    It is good that many of us have found ways of getting around the problem IN THE SHORT TERM.

     

    The fact remains that we have all been sold faulty and very expensive bits of kit (I am hoping that mine will last at least three years) and at sometime in the future I may need that faulty HDMI port.

    In response to the below, and to help get straight information out: I picked up my replacement Mini after Apple pulled the 10.8.2 update.  I have personally experienced the dropouts & snow-glitches on two seperate Minis on both 10.8.1 and 10.8.2.

    Yes, I agree. The problem has not been solved by any means. Many workarounds just means many inventive users experiencing the problem. I want to use my mini in my home theater with HDMI connection only. My workaround, the mini display port->DVI->HDMI adapter-bundle (+optical audio cable) is really only a temporary  workaround. Also I might need the TB port for some other peripheral device soon.

     

    I wouldn't be surprised if all reviews, tests and articles so far have been done using thunderbolt, or more likely, the Apple provided DVI adaptor, hence brilliant reviews. Also some users seem to experience the flicker much more infrequently (couple of times per day) than e.g. I did (once every 3-10 seconds). This infrequent might go unnoticed for a long time. All users wouldn't even pay attention to such ("What was that? Oh well, whatever, nevermind").

     

    I'm getting quite annoyed by some unnamed fanboys playing down the problem of others. Such seems to more of a rule than exception what it comes to these communities. If you can't help, don't patronize us.

     

    And by the way, if somebody at Apple is screening this, you are more than welcome to contact me for debug info, system configuration, video of the flickering TV etc. Since this is linked to my Apple ID I'm sure you have my contact details. I'm at CET+1.
