New iMac cloudy corners

[moey2k2001]

Hey

I want to get myself a new iMac late 2015 i7 4ghz 32ram fusion or maybe ssd.

I know that previous models had a few issues with heat and with certain conditions created cloudy marks on the screen corners ranging from dark to light grey.

My question, does anyone know if the new models 2015+ create this issue too? Has this issue been addressed? I hate to spend 4000+ and then this issue appears. My 2011 iMac has these spots and I never repaired it cuz I had no warranty and it was too pricey.

Any tips would be helpful please.
Thanks.

I've never heard about that issue. Got a link?

I never heard of that issue, I don't think there's many threads here on it, if there is, I missed them.

My 2015 iMac is great, no issues with the display

if you google cloudy imac or smudge on imac you will see there are bunch of people that have this issue
ifixit offer suggestions how to clean it or get rid of it but apparently its between the glass layer...

pictures are hard to take since its a screen and only seen when u place a white background. from what i have understood from other people too, it seems to be heat, dust, humidity... and maybe a hardware issue. maybe just one batch was affected. but the problem seems to be more common.

the thing is, the issue only appeared after I had the imac 2011 model for two years. I still have it and it works fine except that the marks don't go away.

What are your suggestions on "cleaning" the device. I want to be prepared to take action for my next device which will cost me 4000-5000. Obviously the fans also get some dust in...
[doublepost=1470930460][/doublepost]here is a guy portraying it on a youtube vid

also there are bunch of threads "deleted" from apple's own forums for this issue. check out this entry taken from https://discussions.apple.com/thread/2300580?tstart=0


I've had my screen replaced FOUR TIMES. I'm a mechanical & systems engineer and work with these products every day; I know exactly what is creating the problem.

Most of the people on here have good intentions but they confuse what they observe with science; the problem is a poorly conceived air filtration system combined with high-humidity environments. Living in Florida, the tropics, summertime in the midwest or using a humidifier is the catalyst because dust particulates in the air contain enough excess moisture that they clump up behind the LCD panel and accumulate into what look like giant stains.

The solution for Apple is simple; a removable HEPA filter in the base of the iMac would filter out particulate down to 3 microns. One simply pops open the HEPA filter's cover, removes it, rinses it our or replaces it and the problem would not occur.

Instead of solving the problem Apple would rather censor this thread. It is the worst kind of incompetence. So, yes, I will gladly testify for you. Email me before this message gets deleted. You know the idiots who censor this thread will delete this very, very soon.

I've been part of this thread for nearly two years. I was one of the original people complaining about the problem (and originally thought it was a heat issue.) Each time my "screen goes bad" I've studied the problem in greater detail. Since I have AppleCare I demand they repair the system in my home and I thoroughly document the repair process. Its amazingly simple; they just remove the glass bezel, carefully remove the LCD panel and then replace both...without dusting the system or addressing the real problem. Inevitably, the dust spots return. I've wiped the dust with my fingers; it is clumpy due to moisture.

Apple loves to point a finger at you the customer. "Well, perhaps it is a lifestyle issue." Sorry, Apple, living in Wisconsin or Florida isn't a legit reason for you to dodge a basic engineering flaw!

People have blamed cigarette smoke, heat, pressing too hard on the LCD panel (which is just dumb; you're pushing against thick glass and can't affect the LCD panel at all with pressure) and a variety of other pet (and scientifically unsound) theories. It is so amazingly simple: its just the unfortunate collision of humidified dust and poor filtration. The reason Apple doesn't fix this is because they don't know how to properly isolate the problem and test. This isn't a conspiracy of geniuses...its a conspiracy of dunces. They aren't out to get us...they just don't know how to fix this. They designed a beautiful computer in a low-humidity environment and have never spent enough time on air filtration.

These seem to be very isolated incidents. There is no indication of a wide ranging problem on a computer that sells millions of units, if you take notice of every random problem recorded on the Internet you'd never buy anything.

TRUE. But the issue is NOT random, and I know from experience that the issue is not a minor incident though. My current imac has that. a friend of mine also. so maybe bad luck if it was one person... but in that case, it's not. Sadly apple never addressed that case or offered any solution even though a lot of people asked questions regarding the matter.

The screen was always swapped out in most cases but if one is unlucky and apple care runs out or it happens one day after apple care, what do u do then?

I just want to be prepared...

Two people don't equate to a wide ranging issue. I did some googling and there seems to be something going on but I don't think its a major issue, otherwise more people (here and elsewhere) would be screaming about it. Lack of noise on this topic can be very telling. Either way, its awful, that its happened to you, and hopefully you can get it repaired.

Well again, I don't care bout it since the imac I have I want to get rid of. Not really 2 people but again not everyone seems to know of this issue. I assume maybe it may have been a batch that was messed up... Anyhow, have you heard it happening to the 2015 models by any chance? Thanks

Although I don't have a 2015 iMac, I do have a Late 2012 iMac, which shares the same design.
Since the Late 2012 model, the panel is fused to the outer glass and I would imagine that this would keep out dust or other contaminates that might have caused the cloudy marks, has it would be air tight. Whereas before, the outer glass front was separate from the panel.

Perhaps the cloudy screen issue you've mentioned was isolated to the pre Late 2012 iMac redesign?

Nope, as I mentioned, until you posted this thread, I had not heard of this occurring at all, never mind to a specific model.

My 2012 model had it... eventually the entire iMac was replaced and now my late 2014 5k also has the problem. I'll be waiting for a new iMac to be announced before I take it in for repair however as last time they damaged the stand, then the case and finally after refusing the replacement case the entire iMac was replaced.

John.

I think you may be right. I looked into it and it seems to be legit. Thanks on ur input
