iMac 24 Aluminum screen burn-in?

Heh, I had 6 of them + 2 tested in the shop. Last one today. Still the same.
Just see that posts about, they just keep on coming.

Anyway. Did you tested in specific conditions like plain or pattern background, brightness on low level (minimum is the best)? And then, behold! the great hardware gradient absolutely for free!

Anyway, the only thing we can discuss now are now is the health of your eyeballs (pardon me) cause it has been proven on serious of forums that it's a design fault which cause overheating with result of visual distortions like uneven luminescence of the screen or smudge.

Probably there is no point of buying iMac's until they're gone be redesigned which is at least 1 year.

Crap you just made me think if its really worthy to buy this beutiful/low-quality computer... What type of mac computer should i buy instead? I love everything about the iMac but i really think it's sad that it have serious problems with the display...

No i didn't try the store resellers iMac with plain background and with brightness on low level... i shall visit the store again and reconsider my mac-computer buy... =(

Does the problems with the display come directly from the store or does the gradient lightning getting worse along with time? Im not a professional photographer och designer so i don't know if the display related problem is big for me?.. Does the computer have thermal issuses even if i install the smcFanControl application? http://homepage.mac.com/holtmann/eidac/software/smcfancontrol2/index.html

It comes directly from the store. After about 15min from turning on an iMac it's showing it's "full class" 😉.
I haven't tried the fan controled but i haven't heard anyone who got it fix with that but I've seen oposite:

You'll loose peth of colors with that but for web browsing or word processing it's OK, but in that case I don't see the point of spending 1,5K euro or $ for such a tasks.

You really should try smcFanControl, i have heard that the computer will run much cooler when you set the RPM on the fan a bit higher, i don't know if its a solution to the displayproblems, but it should make your computer lifetime longer! 🙂

Soo you think that the displayproblems don't getting worse with time? The gradient on the display isnt a bigger problem after two years using? (excuse my english...)

OK maybe when I'll order another one for test purposes. (since they deliver it and take it back for free)

I'll do the test with Fan Control but I don't expect miracles. realy this topic would be over long time ago if this would work.

Okey it would be great 🙂 Im eager too hear from you soon!

Maybee people that solved the problem is to lazy to help other mac users, and this is a support forum - people with problems write here often...

I really want a iMac, but im afraid of the problems i read about :P

I solved my "burn-in" problem.

Just today I noticed the burn-in problem on my screen and I freaked. I couldn't believe it! I deal with photographs a lot of times and I can't have that interfering with what I see. Then I saw all of you had the same problem.

I read what someone said about heat might cause the problem. I put my hand on top of the iMac and it was blazing hot. Not warm, almost too hot to even touch. So I installed that SMCfancontrol software and my computer was running at 148 degrees. I don't think the fans inside the case were working at all! I immediately shut it down for about 15 minutes took a can of compressed air and blew out the vents. A ton of dust came out.

Now it's been down to 88 degrees but I'd really like to know why my iMac was 148 degrees. Anyway it did not take care of the burn in. I bought two 2" suction cups from Walgreens and lifted the glass screen off (I don't recommend this. It's VERY fragile). Then I massaged the LCD with a microfiber cloth (you cannot use anything else or you'll scratch it!), I restarted and the burn-in was gone.

But I sure as **** am going to make sure I don't leave my screen idle for 10 minutes like it was.

I've had a 24" Silver iMac since Aug '07, and just yesterday started getting burn-in issues. I think the room temp got too hot, and also the iMac. And then since my son left Photo Booth running on his account, I think my screen saver wouldn't cut in. I came back after a few hours last night to see screen on with content, not the usual Flurry saver or black screen.

I've never been obsessed with screen saver, under the false assumption that LCD's don't have burn-in concerns. Just got a quick education on that error, and on the relatively low quality control in Apple production. When you make good looking stuff, I guess you don't have to make it work well underneath in every regard. Style over substance... in Apple's case: form and function over fortitude.

So, now I've learned of JScreenFix, smcFanControl, etc. etc. I have a white screen as saver right now, and we'll see how that goes. I'm gonna blow out the collected dust in a minute, but I'm afraid to get suction cups, pull out the glass, and massage the LCD. Are there any other material remedies that I've missed?

Will report back any beneficial outcomes. Just wanted to chime in and increase the occurrence counter on another iMac with screen burn-in. BTW, mine's an early Silver edition and the screen's great otherwise.

I've had my iMac 24" 2.8 Ghz since it was launched. Just today I noticed burn in of an application that has only been displayed in that location for less than 24 hours. My screen saver comes on after 2 mins to a black screen.

I have not done anything different than before. Seems, odd, I can see my "Call Controller" clear a as day!

I've had the same problem for a few months now. I started another post with pics on this issue because I wasn't aware of the existence of this one. Here's the pics.

First image: Look at the camera objective reflected: you will see the black line that cross it vertically along the screen.

I bought my 24" Aluminum iMac back in October 2007 (It was a Tiger machine when I bought it)

The problem started in february. I wonder if i should buy the protection plan before the first year warranty expires just in case Apple decides to do something for this faulty screens...

Right now I'm trying the fancontrol solution to see what happens. Anybody knows to which fan speed is preferable to set the program?

Thanks.

Yep, smcFanControl did the trick. The "burn-in" is fading away.

It's such an hassle that now my iMac is a-humming like an a Capella singer, but it's always better than those pesky lines since I have to do graphics with it. And it's still quieter than any modded computer I've ever owned.


Anyway, my iMac is not MobileMe, so it would be nice if Apple decides to do sometimes for us - a flock of poor image ghosts janitors.

Hope it won't be a 60 days subscription extension.

I have the same problem as you guys only I have it with world of warcraft. A few days ago i noticed that my Action-bars and my health bars of the in-game interface have ''bunred-in'' on to my screen. Now I am trying the fan solution at the moment, but my iMac sounds worse then my old PC now. I was just wondering if anyone has any information on were Apple stands on this issue, are they gonna fix it or are they gonna follow in Microsoft's footsteps. Because I am really thinking of just taking my iMac back and buy me a killer PC machine for the same money.

This guy has our same problem. He's the one who made the great iPod mock-up that's traveling the mac web in these days.

His Alu 24" iMac was stil under warranty and it's now been shipped to the assistance to get a screen replacement.

He's been very kind and he'll keep me updated.

So for who's still under warranty (I am and I'm defenitively buying the 2yr extension) there's still a chance!

I had the same issue. Persistent ghosted images that can change fast/slow but do not go away with jscreen, with an attached dell display that has no problems.

I installed the fan control software like clearpage suggested, upped the fan speeds, and that has solved the problem.

Thanks!
