New iMac 27inch screen flickering/tearing/shutoff

I have been experiencing some problems with the all new iMac 27inch display.
At non-fixed intervals i will get one of the following:

Screen distortion/flicker somewhere random in the screen (feels like it is more in the lower part) that looks like a horizontal bar of about 2-3inches just popping in and out of the screen.

Screen will go completely black for a second and then come back on. Sometimes 2-3 times in a row.

Somebody else already made some video-clips about these problems, I am experiencing exactly the same behaviour.

Just to not that in the course of writing this post my screen has flickered 13 times and has gone black 2 times.

iMac 27inch 3Ghz 4GB 1TB ATI 4670, Mac OS X (10.6.1)

Pardon me jafrica but who are you Glenn Beck? You are welcomed to disagree with me but don't need to suggest I am ignorant unless you can back up your statement and at least explain your justification. If you want to throw negativity into this thread with no substance then you don't need then to say anything as it serves no real purpose.

So, let me clarify my points prior, to maybe clear up any bias I may have introduced into my post on this thread. By your comment I presume you probably did not read my other post explaining my problems out of the box with my iMAC. In explaining my GLOWING experience with APPLE CARE I did not mean to express the notion that APPLE as a company is faultless.

I am only saying that in my 30 years of experience buying various forms technology (Packard Bell, Dell, Compaq, Canon, Indie Tech systems,Microsoft: DOS,Windows 95, 98, ME, VIRUS PROTECTION??? Et al) all of it a nightmare of complication, confusion and unbelievably unreliable stability or function and tens of thousands of dollars to keep it just barely workable until the next crisis) or any consumer product, my long term and overall experience with APPLE has been COMPARATIVELY BETTER than any other company I have ever had to deal with. Have I had difficult or less than knowledgeable service staff issues in the Apple Stores which left me frustrated sometimes? YES! Have I delayed purchase of this latest upgrade due to my concern and fear from experiences with PC companies in the past (Dell and Gateway) that maybe as big as they are getting APPLE may start stripping the customer service for reducing profit loss? yes! But even with these questions I see and experience a better level of customer service with apple more consistently than any other company I have ever dealt with.

Recently, a close second would be Crate and Barrel. I was sent a set of dinner plates and bowls from family at Christmas. The bowls came in a set of six and one was chipped on the edge. I called, explained and they sent a replacement to me OVERNIGHT. The "One" chipped bowl they sent was an entire new set of SIX. I called explaining they made a mistake hey said no please keep the originals and the new set no problem! They bent over backwards to make sure I was happy with the purchase. That is customer service!

I have a great deal of empathy for those who have had the issues with the earlier flickering issues and yellow screens. I am sorry also if you have been one of those unfortunate enough to experience these issues and truly hope it gets corrected to the point that you love your iMAC you eventually end up with as much as I love mine. That being said my main point is that every tech product is likely going to have problems. That is the nature of such a complex and delicate technology. But as for resolving the Screen Flicker with Firmware corrections and how the yellow screens will be corrected, I try to consider all the possibilities. That during Steve Jobs facing death, the iPAD and iPHONE 3G development and SDK expansions, the transition of power of the company during Steve's recovery, all the maintaining it's momentum and integrity and retaining the vision of the company, and relocating manufacturing assembly of the new line of iMAC's to Shang Hai, it may be difficult to maintain absolute quality control to typical standards. So I am being optimistic that since iPAD is now launched that APPLE can refocus on the quality corrections of the rest of the product line where any flaws exist. So what is the excuse for your attitude?

And again, I ask, how am I so ignorant jafrica ???

Have been reading this discussion, we got the 27" about 3 wks or so ago - have not posted until now - I just installed the 2nd update from apple for the screen flickering. I haven't experienced the yellow tint - just intermittent flickering now and then and it happens after it's been on sleep. hoping this will solve the problem! will give it a couple weeks to know for sure - fingers crossed for everyone! really love the 27" aside from the flickering once in a while...

Hey NZAC10,

Thanks for your response as I want to add to it as looking back at my original statement it dawns on me or at least I presume "jafrica's" response was to the words in my post which were capitalized, "IN AMERICA". I assume now this was taken to presume that I have some general prejudice with internationals not being acceptable to serve me in relation to a problem I have concerning a technical issue or consumer complaint. MY emphasis on America and someone "Speaking Clear English" was that as the PAYING customer, especially at an additional fee for tech "SUPPORT", I would assume and EXPECT the first requirement of that agent to be the ability to support and resolve my needs with regard to the issue I called about.

My back story to that statement is partially clarified a few posts ago. I feel I missed the point of "jafrica's" reaction. I was and am coming from a frustration all the way back to being a PC user and anticipating purchasing a Dell computer when it was the hottest thing around. Then Michael Dell Retired and they hired a Wall Street Whiz Kid to come in and take over. His first "Jack Welch" action (Look up Jack Welch of GE to understand his role in theory and action of strip mining companies for profits margin increase to shareholders at labor and middle management expense) was to strip the Customer Services role to the consumer which Dell continued to claim as the best in the WORLD for 3-4 years ahead. (Which it was ORIGINALLY) Then he cheapened the manufacturing. By the time 2-3 years went by Dell customer reputation was ruined. I switched during this time to the idea of buying a Gateway...because of there Stellar customer service! Then they got strip mined. Reading CNET reviews constantly Dell was repeatedly discounted by customers with nightmare tales of having to talk to tech support in India. My realization in researching this was that they could talk the talk but had no understanding of it's meaning. It was phonetically scripted right from the manual which came packaged with one's computer. This was not UNDERSTANDING how to troubleshoot a computer problem. It was merely the appearance of such. So my whole point was not any issue with internationals serving customers. It is with CORPORATION's whose only vision of motivation is PERPETUAL PROFIT. Not properly training staff to handle consumer issues and not making a QUALITY product in the first place! It is with their assumption that is is okay to ship off responsibility to the consumer and not stand behind their product or the consumer which is who made them so profitable in the first place. So I felt the need to clarify that if I am frustrated with anything it is the impersonalization and commodity we are as statistical numbers to the corporation. I don't mean to sound so serious and I want to get back the issue of this thread clarifying the yellow screen tint issues and the flicker resolve as I am seriously delayed in updating my business technology except for these issues. But to me it is worth the wait. I unfortunately don't have the time or financial resources to buy on spot and deal with the consequences of tech issues so I always give a period of time after a release to buy to make sure there are no MAJOR issues to contend with. I SERIOUSLY look forward to my new MAC!!!!

Nexus600............Sometimes the English in the US is not perfect either. We speak about forty dozen different versions of it within the Continental US, but it's still good to hear when making a call to a service rep.

I'm glad to know that Apple seems to try to cater to everyone regardless of their origin.

BTW, that "real American" thing was just intended for one previous poster who seems to think waving the American flag, and calling himself a "citizen" gives him good enough reason to insult other posters, and refer to them as ignorant.

Update for me...

Still waiting to get my second i5 back from the service centre.

Since Thursday 22/1/10, they have replaced the screen but are waiting to hear back from Apple engineereing in the US regarding the iSight pixel issue.

It has now gotten to the point where it is costing me money as I run my invoicing from that machine. My January invoices will now have to wait until March to be paid.

This downright *****.

Robbie.

dawage and nzac10............ I think most of us here appreciate and understand your comments.

Apple warranties and service are the best. Part of what makes them so good to the "real Americans" that use them, is the fact that we still have one company that we can call, and actually get someone who understands English, and speaks it fluently. I hope all of our foreign user friends have the same type of experiences when they seek Apple Care services.

Although it may be a bit off topic, it does raise a bit of my curiosity .......


Hi pazuita,
Just to satisfy your curiosity!
Here in Paris as in Montreal (Salut Nexus600), 
we usually get service from Apple, in French. I tried once my American which is probably not the best, but good enough to buy a Mac.
Just have to say 'I take it' and give them my Amex.
It worked also when I said : 'It does not work like it should'. 😉



BTW Pazuita, you know what, they happen to speak English in Shanghai too. Not the real one you got in Texas but who cares.
What a small world, even if nothing is bigger than Texas.
Take care,
Jacques.

ps: my iMac i7 is running wild!

I like many here, am waiting for everything to be resolved before buying one however now that I have waited this long I am seriously thinking about holding off until the next Imac upgrades.

The graphics card used on the 27" 4670 was always an entry level performer and only has 256MB, the 4850 is better but still only has 512MB and they are both getting a bit old in the tooth (first appeared in 2008).

USB 3 is the technology of choice so it surely will be on the next upgrade of the imacs.

Am I not buying into old technology just to get the screen, surely waiting another few months is worth it?

No?

Why has been Steve Jobs a little bit angry with Adobe? Can it be that the Flash Player caused some issues to the new iMacs? Probably stupid questions and I hope somebody can explain me, what was wrong with Adobe's Flash Player, but the fixes have been software related and therefore I'm still wondering what the two firmwares changed?

I'm thankful, when a medicine helps me, but I always prefer to know, what I get and why it helps. Why does Apple not explain us, what this display firmware is changing in the software configuration?
