IMac Screen Problem?

Hi, As you can see in the image below, there is this bright squiggly object in the bottom right corner of my iMac's screen. The computer is just under 4 years old. It is much more visible in person, and the artifact, or whatever it is, has depth to it, indicating to me that it is inside the screen or at least behind the glass. I have just started noticing this now. Any ideas? Thanks.

Another 27" imac screen problem

Hi all, just wondering if any of you have encountered these screen anomolies before (video link at bottom of post)
basically, ive had my mac a few months now (traded a constantly overheating and blowing up macbook pro for it).
I am an animator and so occasionally use my mac to render out 3d animations, meaning leaving it going for about 6 hours on average for a few seconds of animation, i also occasionally play games on both osx and windows 7.
Anyway it seems to have developed few different problems with the screen which at the moment i believe to be heat related.
Firstly there is the 'fog' problem that covers a large area from the top left of the screen (and a little of the top right) only its been there for weeks and weeks now hasnt got any smaller even when the machine is left on or left off and before people start telling me to remove the glass panel, im not going to do that because of dust sticking to the inside and also because the 'fog' has not behaved in the same way as it has for other people (dissapearing and reappearing as condensation would)
secondly, in the top left of the screen an area of crazy shaped wavey lines which look very much like they have been caused by heat and is a good few inches in length has appeared, although it this problem cant be seen when the screen is on, for a £2000 computer is annoying especially accompanied by other problems.
last but not least two small round marks have appeared near the centre of the screen which at first impression seem to b burn marks, perfectly round, slightly brown on the inside fading to white (colour may b a little difficult to tell in the video)
none of these problems are visible when the screen is on, and in the video the screen is a little grubby but i assure you i have tried cleaning off these marks to no avail.
it seems from my experience with apple computers that the products nowhere near match the service which is a shame because the service is the best i have ever experienced anywhere
any help/suggestions would be greatly appreciated
thanks

this is what surprises me, you live in california where apple must test its products, which without a doubt has a substantially hotter climate than Birmingham UK which is has its fair share of heat but only about 2 or 3 weeks of the year could it come close to california temps, yet every mac i have had some problem due to heat, i do some pretty demanding stuff with this one but nothing that a £2000 machine should have a problem with (i can understand my macbook pro blowing up seeing as it often got waaaay too hot)
i'm beginning to think a mac pro may be the way forward which would be an option for me if i was in the US but for some reason i cant figure out the UK market is being discriminated against to the tune of an extra £500 which i believe is nearly $800 at this moment in time.
quad core mac pro starts at $2499 (£1500) where as here it starts at £1999 ($3100)
a shame considering i cant get one because i cant afford that one and a screen....whats going on apple?????
Well I just discovered a couple of things I am concerned about. 1) I have a noisy Western Digital Drive. I can hear it read and write. My iMac Quad Core 2.8 is dead silent. It has a Seagate Hard Drive which is supposed to be noisy but its not. The Western Digital Dives are supposed to be quite. 2) I also have a buzzing noise coming from the exhaust ports when the screen is turned down low or when it gets hot doing intensive tasks.
The screen itself is great, no yellow tinge as some have noted.
I am considering getting a complete replacement.
Thanks!

24 inch iMac Screen problems after 10.5 upgrade

After upgrading to 10.5 i have had many issues with the display my iMac (white) 24inch Core 2 Duo. I have corruption resulting in horizontal lines across open windows and in some cases on the desktop itself. Some of the button text turns bright green. The iMac in question was purchased with the NVIDIA GeForce 7600 GT graphic card upgrade. I have run the 10.5.1 software update and the firmware is all up to date. Has anyone had the same issues? Does anyone have a fix? Help please.
I have upgraded my MacBook with no issues at all!

If your iMac keeps on freezing it could be a hard ware problem, the first thing to do is run Apple Hardware Test on your iMac.

outcome ....new screen and front cover FREE OF CHARGE
Hope this helps anyone with the same problem

IMac G5 Graphic Card Replacement for blue screen problem

When I turn on iMac, I only see blue screen, the apple technician said Need to replace graphic card, Nvidia Gforce 7600GT 256.
1, can it install in IMac? Seem like it work for PC?
2, I had blue screen problem several time, I think I turn on iMac too long, so it burn out graphic card.
3, I have 2007 G5 24" screen model, is any durable and afford graphic card you recommend?
Where to buy for cheaper price?
Do I need to change mother board?
4, can I replace it by myself? Any picture or video for graphic card replacement?
Thank you.

If you look around, you might be able to find someone who will replace just the chip on the graphics card, which is what usually fails. It will take someone highly skilled; they really have to know what they're doing--it's not an ordinary soldering job.
Here's someone who found a non-Apple service to do this, and it proved to be far less expensive than a full logic board replacement. But I think this was in the UK.

IMac Sleep Problem Waking - Screen Black and Pixelization

I am having a screen problem "waking" my iMac (2010 model)
After the iMac is in (deep?) sleep mode
(I have it set to enter a password after sleep mode)
Screen is blank/off
I "wiggle" my mouse or trackpad
Screen is still blank (sometimes it may display my screen saver, but the screensaver is frozen)
If I start moving the mouse or trackpad, it starts "un painting" the black screen. You can see whatever is supposed to be on the screen, such as the logon "button".
It is really wierd. Like a black "overlay" is painted on the resume from sleep screen. As I move my mouse or trackpad, it is basically erasing the black, to show what is underneath. Each movement of the mouse, erases a small black square.
I usually move my mouse around the middle of the screen to uncover the logon button. Press the logon button. The screen magically reappears as normal. I enter my password and system logs back on normally.
It only seems to be when the iMac is in (deep?) sleep mode. If the screen is just blank for short time: I move the mouse/trackpad, and the logon screen is immediately displayed normally.
Any thoughts or recommendations?
There is a few other treads on this issue e.g. on the macrumors site, but no solutions.
Thanks to all in advance.

Hi! When you say "the power light goes off once again" are you talking about the power light on the monitor or the computer? If it's on the computer then it's likely the computer but if it's the monitor it could be the monitor or the video card. You may have to find another monitor to troubleshoot it. Tom

What is the technical 'cause' of the infamous iMac black screen problem?

Can anybody shed some light on what technical malfunction exactly causes the infamous iMac black screen problem? The common solution seems to be a logic board replacement. But what exactly is broken on the logic board? Is it the Geforce chip? Some kind of external driver circuitry? Or something completely different?

I was referring to the many problems also described in this thread (and also in many other places):
http://discussions.apple.com/thread.jspa?threadID=196774&tstart=0
In specific I am referring to machines where all of this applies:
- internal monitor stays black after power-on
- computer boots normally
- external display works normally
- internal display backlight works and can be adjusted in brightness, but all pixels are black
- PRAM reset doesn't help
- NVRAM reset doesn't help
- PMU reset doesn't help
- reinstalling OS / booting from CD doesn't help
- machines with this problem sent to repair come back with a replaced logic board
I'm looking for more information on the technical cause of the exact problem as stated above. So I can attempt to repair my iMac

Imac display problem, the resolution seems to be unusual, top bar and all folders on the desktop background is off the screen

Need help with 21" imac display problem. The resolution seems to be unsual, everything on the desktop background goes off the screen. The resolution is set at 1920 x 1080

Quit the game and restart the iPad.
To quit the game - Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesn't work try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Have an iMac. Problem is I hear the fan noise, yet no power on the screen yielding no power. I have checked the power cord and it seems to be fine. Not sure if computer is a total loss. What would be the next step?

Late 2013 iMac 27 inch screen problems

My screen has many marks on the screen which look a bit like rain globules. They are particularly noticable when the screen is dark and is a particular nuisance when editing video and photographs.
I have only tried wiping them off with a lens cleaning cloth as I am reluctant to risk damaging the screen.
Any ideas or is this a screen problem on this latest iMac screen.
Am using Mavericks operating system

Apple lists these environmental conditions for most of its machines:
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -13° to 113° F (-24° to 45° C)
Relative humidity: 0% to 90% noncondensing
Maximum operating altitude: 10,000 feet
Maximum storage altitude: 15,000 feet
Maximum shipping altitude: 35,000 feet
If you don't believe you are exceeding them up or down, you may have a hardware problem that your 1 year AppleCare may cover. See first if the hardware test booting the 'D' key is revealing:

Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.

IMac 27" i7 "blue screen" problem

Hello,
My iMac "crashed" a few weeks ago and I experienced something resembling windows "blue screen". The screen went black/grey/blue. Rebooting the iMac did not help and after the normal start up procedure (Apple logo) etc. the mac stopped at a grey coloured screen. I called support and together we tried every possible way of restarting the system without success. It seamed to be a hardware problem like a defective HDD drive or maybe worse. I received a list over Apple service partner and delivered my iMac for a thorough inspection. After approx. one week the service partner called me and asked me "what s wrong with your iMac?" Apparently the iMac started without problems and the diagnostic tests did not find any hardware failures. I was pretty surprised that they didn't find any hardware failure. Happy that the iMac seamed to be ok I went home and plugged in the machine. It started without problems. Connecting the wireless key board I discovered that most of the F functions did not correspond to the symbols on the key board anymore. All functions like brightness, mission control, dashboard etc. had changed places. While trying to reset to the F functions to the normal set of keys while simultaneously updating iTunes and the latest security update in the background the iMac screen went black and grey... It started once after the crash and I checked the list of incompatible updates in the appstore before it crashed again... Now the machine did not start properly and I got the same grey screen after rebooting the computer. I am relay disappointed.
Anyone out there experiencing the same problem? Anyone who can explain what's wrong?
I will have to call the Apple service partner again tomorrow.
My iMac is approx. 3,5 years old. i7 processor running OSX mountain lion with a 2TB HDD.
Best regards

Thanks for helping me out rkaufmann87
The iMac works at the moment and I have even installed the new OS X. I called the Apple service partner and they will look into the problem again. Now that they know what to look for I guess they will find the problem and fix it. Hopefully I will only need to change the HDD.
Back to the keyboard. What has happened to the F keys? I need to push the fn key in order to e.g. change the volume on the internal speakers or change brightness! What has happened to the default keyboard setup?
Best regards

Apple guarantees their work, take it back.
