Q: Mac Mini (2012) HDMI losing sync (blank screen/snow)

Thunderbolt to dvi works fine...Thunderbolt(from mac mini) to hdmi???Working??

just to be clear once and for all: the issue is related to HDMI port and NOT to Thunderbolt one. You CAN connect ANY kind of adapter to the Thunderbolt port and it will just work fine.

About the HDMI port: you can connect any kind of adapter and it will NOT work fine, anytime, anywhere, anyhow

issues are: blurry text, loss of sync, snowing screen, blinking black screens, and completely black screen

Have you ever tried to connect mac mini with thunderbolt cable succesfully??

as i told before: yes, thunderbolt port works fine.

i am using a thunderbolt to hdmi and it works

I have just spoken to a senior 'Apple care' representative who has confirmed Apple are fully aawre of the issues relating to the mac mini screen blackouts/snow. He also advised that the team in the 'USA' are working hard to rectify the issues, although at this stage I was not told whether this related to hardware or software. I was advised a software update (10.8.2) was released recently and if the issues can be resolved with an update this will be rolled out, although if the motherboard is at fault this would need to be replaced. Now I have made a contact I will be emailing for updates in the coming weeks and report back on here with any progress to the issue(s).

When I asked about why Apple had not issued a statement, I was just told that he could not comment on Apple policy on the release of statements with this issue.  At least we now know they are fully aware of the problem...

Thanks for the update gooch99.  Something positive(ish) at last.  I did not want to submit my machine to board changes etc. until I was confident that Apple had found the problem.  I look forward to your updates.

lol, it's incredible how things could be different from country to country: Apple Italy told me that they have no idea and no reports about these issues

who's telling the truth?

i never been so disapointed before...

In the UK it came as a surprise both to AppleCare and my Apple store. I don't think that Apple are even communicating internally, let alone to customers who have parted with hard-earned cash for their product.

There has been no noticeable response from Apple to the various threads on this site.

Yes, would be interesting to follow the progress on this.

Apple Mexico (I only made one call)

- Not aware of the problem

- No idea

- they give me a case number

- Take the mini to an apple center (In progress)

*sigh*

I waited, then I crossed my fingers, and ordered.

2.6Ghz with 16GB of Crucial brand RAM, 1TB HD.

Received mini on 11/20, then this morning (11/21) at about 9AM I had my first issue - black, then snow, then normal, over about 3 seconds. No intervention on my part, but I'm worried about it worsening.

Connected by HDMI to HDMI on my Vizio TV.

I can say that the colors are perfectly fine.

I'll give it some more time and then try the MDP to HDMI adapter, but I didn't purchase this to give up the only Thunderbolt port for video out.

Do not expect Apple to admit, officially, there is an issue. Even if support people have hear of it, they likely cannot confirm it either. As a company, they may admit the issue when/if they have a fix, but not before. That's pretty standard for most companies.

On the bright side - Apple's holiday return policy is in effect, so most of us with these minis don't have to return them until January 7, 2013. Confirm this yourself to make sure you are included (based on purchase date) and that I have the return date. I'm willing to give Apple until then to fix it.
