    Hey, gang:

     

    Update about the LCD "water stain" screen problem on my 2010 27" iMac.

     

    Short story: last November 2011, I called Apple customer service and complained about the defects on my 27"  2010 iMac, bought in October 2010. I didn't bother to buy AppleCare, partly on the basis that Apple supposedly builds durable computers.

     

    After politely but emphatically talking with a service rep, she arranged a one-time free screen replacement at the local Apple Store. Unfortunately, we're 11 months in and the screen defect has returned. There are 3 streaks which look like water stains running down the screen, starting at the right hand side of the LCD.

     

    The only good news I seem to be having the same issue as Nikki. They are not too noticeable under most conditions. The intensity of the stains come and go depending on how warm the computer is. They actually will fade for a bit the iMac is off overnight.

     

    Right now, the stains are AWOL. I recently had the iMac into the Apple Store for the HD recall, so I'm hoping maybe they did something when the machine was open.

     

    Overall, I'm pretty disappointed with Apple, the free screen replacement notwithstanding. I spent a lot of dough on this rig and work in a clean environment. I depend on this iMac for my livelihood as an artist, and having a LCD screen degrade like this under normal use is upsetting. I'm figuring at some point, I'll have to buy an external monitor when the screen defects present themselves 24/7. Like an idiot, I'll probably get a Cinema Display.

     

    My big take away from this is that if you buy an Apple product with a built-in screen, absolutely get the AppleCare. You will need it.

    I agree.  When Phil demo the new iMac and talked about the 2mm gap that explained everything.  I've had 2 screen replaced and going on my third and will be taking back in for repair.   Good thing my apple care is valid until March 2014.

    But surely the 2mm gap isn't necessarily the issue.  The blotches were never on the inside of the glass, rather they seemed to be in the actual LCD matrix.  I always assumed it was dust pulled in from the fans which entered the LCD matrix from the rear as the screen was not sealed/isolated from the innards of the machine.

    We're talking about multiple issues here. Dust behind the glass is definitely one of them. Heat damage may be another and I'm pretty sure there are others too (condensation etc)

    I had the dark blotches in the top right of the screen that may be caused by internal heat.

    Mine also had a shed load of dust behind the glass. Probably 60-70% of the screen area.

    I know that the dust behind the screen is easily removed but doing so will risk any warranties.

    The dark blotches aren't 'cleanable', hence the need for a replacement lcd.

    I would be amazed if any of these issues are replicated in the new design, whether it be through superior insulation or removal of air gaps etc. In my view it would be a minimum requirement of the next gen imac.

    NO INHERENT DESIGN FLAWS. In big letters on the design engineers wall!

    I've sorted the problem once and for all! It was quite simple in the end...

     

    1. I took my iMac back to the reseller I bought it from and demanded a new screen (under Apple Care warranty).

    2. I sold the iMac while it still had some warranty left.

    3. I bought a Windows PC.

    4. I swore to never, ever, ever, ever, EVER buy another Apple product.

     

    One of the most liberating things I've ever done. Ended two years of torture using that piece of cr@p.

    2. I got my iMac back in a week

    3. I didn't have to buy a new PC (windows or otherwise)

    4. I didn't feel compelled to swear at anyone or anything or blacken my mood in any way

     

    It was a delightful service experience.

     

    So why the hostility/anger/bad karma in your response? Why did you have to endure 2 years of torture? Did you enjoy being tortured? Are you always in the habit of 'demanding' when just asking would work?

    Just because your experience was good, doesn't mean everyone's was, and Apple outright denies there's an issue.

     

    For example, my iMac is on it's fourth display.  I've taken the issue as high as Apple Executive Customer Relations, and ultimately the determination was that iMacs were not designed to be used in places with "high humidity" such as my former residence in Ohio.

     

    I then stated that I had since moved into a brand new building in Chicago, literally hundreds of feet from a flagship Apple Store, and the issue had still recurred.  Apple's response?  The humidity in Chicago is too high for iMacs, and that I will be denied future LCD replacements unless the issue recurs in an area with lower humidity.  Apple is literally selling iMacs mere feet from an area they claim is unsuitable for iMacs!  I was also told that both humidifiers and dehumidifiers can cause the issue (which obviously make no sense), though I use neither.

     

    If you read the thread, lots of users have been denied warranty replacements on defective panels.  Asking for a replacment, as you've suggested, doesn't always work because Apple actively denies there is a problem.  That's the issue.

    A lot of us here are mere 'amateurs' in the display replacement arena so haven't yet reached your levels of psychotic anguish over these problems. I have only just had my first lcd replaced so I'm quite laid back about things. I might feel different if I was onto my fourth replacement.

    I have no knowledge of US consumer laws, but I know a little about UK consumer law, and if expensive goods are consistently defective they must be replaced. Goods are expected to have a 'reasonable' life span, consistent with the money spent on them. So if I paid £10 for a piece of bargain basement electronic equipment and it fails after 2yrs I probably don't have much grounds to complain, however, if I pay £1500 for an imac I should reasonably expect to get many more good years fault free service. Add to this scenario expensive Applecare add-on warranties and statutory parts and labour warranties for replacement bits and you have the consumer rights equivalent of a water tight case.

    I doubt anyone in the UK has been fobbed off by Apple in the way you describe, but would be interested to hear from anyone who thinks they have.

    I can understand your disallusionment with Apple products, but I'm afraid that I, and apparently many others here, are still complete suckers for their nice shiny boxes.

    I also use a pc every day in my job and it's total cack! haha

    Completely agree.  The first replacement: no problem, stuff happens, minor inconvenience.  Second replacement: starting to get annoying, but they were sympathetic and fixed it.  Third replacement, and subsequent blaming of the aparently exotic lands of midwest America: not cool.

     

    Consumer protection laws are practically non-existent in the US.  We have them for automobiles, but they're weak and very rarely used.  As far as I'm aware, for everthing else you're on your own.  In Europe I seriously doubt Apple could get away with claiming your warranty is void because you live in a humid environment when they're actively selling that product less than a block away from your home, for example.

    Booked my Apple iMac 27" 2009 in for replacement hard drive through their 1TB Seagate replacement scheme. and mentioned to the guy that I was not very happy about smudges on my original LCD panel.  He ran a couple of checks and said they would replace the screen FOC.  Just got my iMac back today with brand new screen and hard drive.  23 months out of warranty and not a penny to pay. 

     

    This is the first time in years and years of owning all sort of Apple devices that I have had any faults and personally I am delighted with Apple's after sales in replacing these expensive components, nearly two year out of warranty, without any quible at all.  Oh and last year I got a brand new 6th Gen Nano as part of their Nano repacement  programme for my 1st Gen Nano which was actually still working fine.  I'll be sticking with Apple and have no hesitation of ordering a new 27"iMac when they become available.

    Not sure if this has already been noticed or discussed elsewhere, but judging from this pic (http://cdn.pocket-lint.com/images/J6vr/apple-imac-2012-preview-pictures-10.jpg?2 0121024-200151) there does not appear to be any rear-top ventilation "exhaust" port as exists on the now-prior generation of iMacs.

     

    I know there's two schools of thought as to the cause of the screen smudge issue (one being heat / burst LCD cells, one being dust from the surrounding environment, or maybe a third combo school) but I figure the absence of a top rear exhaust port is fairly telling for both of these theories:

     

    First, if air flow within the machine is not traveling up the length of the screen and out the top, maybe this reduces or eliminates the amount of dust that could become trapped within the screen? And that's to say nothing about the new thin screen tech and total machine redesign which hopefully further insulates from any external contaminants.

     

    Second, I feel like the lack of the top rear exhuast port speaks loudly to the idea of a much more efficient system of internal air-cooling for the hot-running components in this machine. If you've got a single centered fan exhaust port (kind of looks like two fan exhausts side-by-side at the bottom of the pic linked above, but you get the idea) then maybe the air cooling is that much more focused and efficient. I only mention this because as I run my hand over the top rear on my 27" iMac right now I can feel hot air emitted from seemingly every part of the top exhaust port which seems to be much less targeted to the components that need it the most.

     

    Full disclosure; I'm on my second screen replacement (both went great no-questions-asked by Apple, but also under AppleCare through the end of 2013), and all of the above is written by a layman with little knowledge or understanding of what goes on under my iMac's skin. Just thought I'd throw in my .02 and spread my optimism for the new design!

    Hey you guys and dolls...

     

    think different (quote Steve Jobs) - think positive!! Your IMac is the ultimate fine dust filter system for your home air climate! Apple knew what they developed and they evaluated the clinical trial results of cancer related to home air fine dust contamination of IMac-users. The results should have been negative otherwise the very new IMac wouldn't have completely new display panel -concept....

     

    IMac 27", late 2009, I7 - guarantee LCD panel replacement 2011 - same BS smudge issue after three months....

     

    funny, my first IMac (first Intel-version, 21") still running, has no panel screen smudge at all......

     

    and very funny :

    iMac 1TB Seagate Hard Drive Replacement Program

    - notice I received via email from Apple last week...

     

    funny, I had to replace my 1 TB Seagate HD in June for 250 Euros on my own cost... Prior the replacement I had weeks long of  "bouncing balls", no time machine backups and the power of a 286-Intel PC.....very disgusting!!!!

     

    sure, I contacted Apple support, now I'm waiting for a response towards refunding...

     

    funny, the smudge display issue isn't first priority at Apple - It should be!!!!!

     

    I otherwise love this machine, but....

    I think I first noticed this problem a year and a half ago and also posted in this forum. Long time I suffered in silence - although its bearable - its most annoying for a product bought primarily for the display... its all been said many times...

     

    I almost forgot about it as Ive not used the machine as much since owning an iPad. I also got the seagate hard drive replacement email.... Took it to my local store (UK) - casually mentioned the screen issue and asked for it to be looked at. They said its also covered to replace the LCD for free! Almost two years out of warranty! I'm most pleased but wonder if the same problem might come back after a few months... Fingers crossed!! Totally mixed feelings towards Apple.

    Well, my grats.... nice move from Apple..... I would of tried the same thing if I would have needed the hard drive replacement... Do you have any information from Apple (UK) if this is a new policy to satisfy the disgusted IMac customers in the whole EU (incl. GER). What's your impression - did you have luck???? My Mac is one year out of warranty.
