Q: Mac Mini 2012 video blinking out

HDMI to DVI has the same problem!If Thunderbolt to hdmi or thundertbolt to dvi has the same problem means that the problem isn t the hdmi port but the intel hd 4000!!

Me the only problem i had is that the screen is going black or snow once per day!The colours was great!I use hdmi to hdmi!

No Georgiosko,

My Thunderbolt to DVI is working fine......

Your diagnosis may be correct but speaking purely for myself the DVI (via supplied adapter) and HDMI output from the HDMI port doesn't work but Thunderbolt to DVI using an Apple adapter works.

I cannot recall seeing any posts on this forum identifying a problem from the Thunderbolt port.

I have the same issue as everyone, using the supplied hdmi to dvi adapter. Sometimes black screen, sometimes static snow.

Cheers

Please log a call with Apple Care if you haven't done so already.

I'm new to Apple, what a moment to change!

Do they have people who monitor these forums and comment? Microsoft have people called MVPs who at least give readers the impression that something is being done.

I haven't noticed a comment from Apple yet? Has anyone else?

My screen hasn t dvi port!!This is the reason that i want thunderbolt to hdmi!But if the thunderbolt to hdmi has the same problem this means that the problem is at the intel 4000 and not at hdmi port!

The thread is getting too long for people to remember every detail so let me restate that my Thunderbolt port failed entirely. The mini went to sleep on schedule, woke up the next morning to find the port died in its sleep. That left me with just the flaky HDMI port. No amount of troubleshooting by myself or the Apple techs could revive the port. The Genius at the Apple Store wouldn't even look at it as he'd seen the problem before. I returned the mini for refund.

Please note that Macworld is asking for people to contact them if you're having problems. Presumably, they'll do a story on the problem and that would raise the visibility of the issue so perhaps others would come forward.

Re: light colors are gone for Mac Mini (late 2012)

19 nov. 2012 00:09 (in response to DLDante)

In my case: (My monitor is HDMI only)

Bad colors:

HDMI ->  Display

HDMI -> Apple DVI adaptor -> DVI_HDMI adapter  -> Display

TB -> third party mdp to HDMI adaptor -> Display

Good colors:

TB -> Apple DVI adaptor -> DVI_HDMI adapter -> Display

my dvi_hdmi adapter is a very cheap one (HKD 30)

___________________________________________________________

And my Thunderbolt_HDMI adapter is a very good one (Apple)

Late 2012 base i5 4GB MINI got Nov. 1.

HDMI to Samsung t24b350 monitor.  Good color, black flickers 1 - 2 sec few times/day since I got it.  Went to Apple store to report but have not yet left for overnight check. Love this computer and problem doesn't seem to be getiing worse and is still livable ... BUT I WANT IT FIXED!

Gosh!!! me too!!!! Snow so far...screen goes out for 4 or 5 seconds and comes back very, very annoying

Ivan,

If you haven't done so already, please log a call to AppleCare, every call logged helps them to understand our problems.

I hope you gert it fixed soon but don't hold your breath!

Apple should supply us with a thunderbolt to DVI adapter. I don't think I should have to buy one to get my mini to function properly. My black screens have gotten longer recently going from 1-3 seconds to up to 10 and I also had to disconnect once to get my picture back. I hope this gets a fix soon. I am getting tired of worrying my screen will turn off permanently. This is a new product, a little info on this issue from apple would be nice. Their silence makes me worry.

Have you asked Apple?

Having purchased my Mini from my local Apple Store the manager willingly supplied one free of charge.

Have you registered the fault with AppleCare? If so there is no harm in asking!

Apple should not supply a thunderbolt adapter, they should fix their products defect.  I have other plans for the only thunderbolt port and I'd imagine others do too... work arounds for a brand new product should not be required for normal functionality espeically when they remove the option ot use expansion ports such as the one and only thunderbolt port...
