2011 mac mini video issue

Hi, my Mac mini 2011 has the identical video issue as the 2011-2012 MacBook Pro see here: http://www.apple.com/support/macbookpro-videoissues/


Does Apple have any similar program for the mini? Identical graphic fail. Last fall I talked to support about it and was told since I was out of warranty... sorry.


But since then they've acknowledged the 2011 MBP has this issue and are doing something about it. But what about the rest of us with this same issue?


Can anybody tell me if they've opened a similar program for their other computers?


Thanks,

Pete

Mac mini, Mac OS X (10.7.3)

Same problem here. In an Apple Store in Brazil I was told that the HDD is defective, and they would like to charge me almost what I've paid for the Mac Mini to replace it :-(
And I'm quite sure the HDD is not defective at all, since I can access all the files...
Apple really should acknowledge the defective mother board / GPU and do something about it, even though it is a 5 year old machine already.

I've sadly had to retire my 2011 Mac mini. It was a good run (cough). No really, given that Apple has been no help at all during this whole ordeal, it's still worked out that I was able to continue using my mini for another couple years. Over the totality of this adventure, I've reflowed the logic board 4 times in all. The longest I was able to use my 2011 Mac mini after this began, was 6 months between reflows. Sadly, on my 5th reflow, something else has been damaged and it will no longer power on at all. Nothing. I've replaced the power supply, but it's the logic board.


I have to say though, even on it's last day, that 2011 was a little rock star. I've never had a complaint about it's speed/performance. My kids played games on it, it's housed my iTunes library, I used to as a vpn client, and for a time it even acted as nat router. We love the Mac mini's, so we decided to try one more, a latest model refurb that has been working wonderfully so far, no complaints. And I have to say, that even now IF I could figure it out, I'd still try to resurrect my 2011 mini again (great little workhorse). I've even considered buying a replacement 2011 logic board, but sadly the cost is prohibitive, given that it's soon to be a 7 year old computer.

Before jumping to conclusions, what are you using for a display and how is

it connected? Are you connected HDMI or via and adapter to the Thunderbolt

port? Have you tried different connection schemes and/or a different display

and get the same result? Have you tried changing cables? Have you switched

display connection from HDMI to Thunderbolt on the Mini or visa versa?

Have you checked with a different display?

Hi Woodmeister50,


Ya, my default has always been HDMI. However, I have also used mini-display adapter. I've used 3 different cables of each. I now use my original hdmi cable on another computer just fine. A lengthy chat with Apple support last October'ish I went through a process with them to narrow down the issue. Even then, they believed it was caused by my video. Presently I'm just using my Mini as a paper weight.


Also Illaass, I appreciate your help and insight.

However, from this article (found on many Mac sites now) http://9to5mac.com/2015/02/19/macbook-pro-repair/ it says the following.

"The lawsuit claimed a defective AMD GPU that did not function correctly because of lead-free soldering causing short circuiting and other problems."

That would indicate it may have nothing to do with the GPU, and likely to do with the solder used.

Thanks to both of you. Maybe they will still open a program for other 2011+ mac models with the same symptoms.

Actually, what I did was reflow my 2011 mini logic board, at home, in my oven. I completely disassembled my Mini, put the logicboard in the oven on tinfoil on a cookie sheet, heated the oven up, baked the board, shut off oven, let cool slowly, then repeat two more times (three in all). It's been three months now I've been using my 2011 Mac mini again. And I haven't been gentle on it. My kids use it for some gaming, and it's our HTPC and iTunes server. I'm under no illusion that this will last forever, but it's been 3 months or so now and it has new life. If symptoms return I'll reflow again.

I had the same issues here (Mac Mini 2011 2.5GHz). Today the screen went pink with vertical stripes and my Mac Mini freezed. I was forced to turn power off. After a short pause and a restart the GPU temperature was still way too high (80°C). Some minutes later the it showed video issues again but I could do a regular shut down.


I've cleaned the Mini from dust with air (if you do that you should block the fan with one finger otherwise it may generate power which can damage the logicboard) and set higher base RPM for the fan with smcFanControl (3300 RPM).

Since cleaning from dust (8 hours ago) I had no more video issues so far although I had a permanent load on the GPU (Unity 3D) all of the time and even ran GPU benchmarks to provoke the issue.


I hope it really was just overheating and my machine is fine now – but this is scary: I found a german company (smartmod) which offers a special repair service for the Mac Mini 2011 with Radeon HD 6300M video issues. They say "Production faults of the AMD graphics chip in the Mac Mini Mid 2011 have become known" (“Bei Mac mini Modellen aus Mid 2011 wurde ein Fehler in der Produktion von ATI AMD Grafikchips bekannt.“)
So possibly sooner or later all Mac Minis with a HD 6300M might fail?

If this happened at a fresh restart of a completely cool machine than it is a really bad sign. If it happens just after restarting a hot machine then there is still a good chance to keep the mini alive. Just never let it reach high temperatures again. My mini runs perfectly since I've cleaned it from dusty and raised the fan speed (zero problems since then). I've bought a really good tool to override the control of my temperatures and fan speed which offers a complex way to setup fan speeds for different temperatures. This way I keep my mini always way below 65°C and it usually is still comparable silent. I've already had higher fan speeds before by using a free tool, but this was not enough for this task because it would have required to overall set the speed of the fan way higher than necessary because it offered only one setting.


Take a look at it, the developer offers a demo for it.

This is my set up for TG Pro, I usually always have Unity3D or Maya open so the GPU is always under comparable high load but it keeps running. While I type this the CPU is 42°C and the GPU is 43°C.
Don't forget to clean it with air from dust inside first (block the fan with the finger from rotating while doing this)
