24"imac with display problems

I purchased my iMac from the local apple store on august 31st, that night after about 2 hours of use I noticed the screen had become quite pixelated I rebooted and everything was fine. Since that day I have had many of the same occurences. I have an appointment tomorrow with the local apple store to hopefully get this resolved. Has anyone else had similar problems? I have taken some pictures to show them at the apple store.

Hi, I have the same Problem with my iMac 24" 2.8 GHz. I used Rapid Weaver and suddenly there were a "pixelstorm" on my screen. I rebooted the mac and it worked perfect. But after a while using Rapid Weaver the screen turned off completely. That happend twice.
The Problem is, that this seems to be a fault in a lot of the new iMacs. A friend had the same Pixelstorm and sent the iMac back. Tomorrow he will get the replaced Mac.
Here you can see, what happens on his screen:

IMac 24" Display problem

Hi,
Im having display problem with my iMac 24" Early 2008.
http://www.hockeystat.net/video.jpg
I cant boot, after 20 seconds the OS freeze.
I ran a full diagnostic with the Hardware Test...no error.
http://www.hockeystat.net/video_test.jpg
Any idea ?
Thank you
Luc

1 - connect an external display; if the external display works ok then there may be a problem with your iMac's display panel or perhaps the inverter board. If the external display does not work then the problem may be with the graphics chip on the logic board.
2 - try booting from the OS X installation DVD? Will it boot that way?
3 - did you recently upgrade to Snow Leopard? If so, did this problem start immediately after upgrading? If you upgraded, did you do an erase & install; or an archive & install?
4 - do you have AppleCare coverage?

Frozen iMac with Network problems

I have a 21.5 inch iMac purchased around Nov'12. Three days ago, suddenly no web page could be opened. I thought it to be a problem of my router but when I found out that I was able to use the Internet perfectly from my MacBook, I restarted my iMac but the problem remained. I shut it down & then restarted it... Now it showed only a white screen with the Apple logo on it and the waiting symbol. This remained till hours until I got irritated and switched off the power supply. I switched on the next consecutive days but the problem persisted. Today fortunately my iMac started.. The home screen has come... It is able to recognise my wifi & Ethernet but does not open any web page. Going to system preferences and then to Networks is hanging the system preferences window. When I force quit it, it says to file a report to Apple.... But the problem doesn't get solved... I always believed Apple as a company whose products never hanged up or faced hardware or software issues!!!

Hello,
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions, reboot.
If you still have problems, this has worked for a few...

IMac ghost display problems (and apple technicians weren't able to solve)

Hi,
So my problem here is quite weird. I tried researching the forum for something like this, but nothing really came close to whats happening to my iMac.
I have an Intel-Based iMac, 24 inch screen.
I bought it on 2008. Since late 2008/early 2009, i had these weird "letters" underneath all my pictures. I work with photography/video editing, so this was very annoying, yet i kept ignoring, since the rest was working fine.
Then slowly the iMac ran slower, more sluggish-y. Like if all life was sucked out of it, sort of description.
Then, 2 months ago, there was a total failure of the HD. I was lucky to be able to back up all, before it didnt let me even enter the computer. It would just think for hours.
I brought it to the technical support near to my home, and i also told them about those weird "letters" on the left side of my screen. They said it was due to my hard disk, and i was, ok...since the hard disk had a failure.
They did a check up, and yep, the hard disk was k.o, evidently. They replaced the hard disk, and told me all was fine.
It did "seem" fine for the first couple days. No more running slow, no weird letters that would distort my pictures (for example, i could see my iTunes music list underneath a picture i was working on photoshop, or a video i was displaying!).
After a couple of days...same story started again. The left side of the screen was flooded by all underneath (open windows, the desktop icons, the texts i had open on safari, basically anything would appear translucently underneath any image or video i would open). Then, flash player would crash every 3 videos, blank cd's would get automatically ejected so i couldnt burn any cd, computer would run slow etc... etc...
So i cleaned up my computer, did a back up, erased all, and ready to bring it up to technical support again. And misteriously, all symptoms disappeared. So i explained to them what happened, and they said probably it was the graphic card.
I thought finally my problem was solved.
24 hrs later, i got an email that my computer was fixed. That it was only a hard disk "permits" issue, and they solved it.
I have had the computer for 3 days, and the screen problem is starting again, and now the permits are perfectly fine in my computer, and nothing comes out as wrong in the diagnostics tool!!!!
I didnt even work with the computer, but now i can see my itunes list through the safari window, as grey letters....kinda 3D, popping out. Its very weird. And i cant capture it because when i take a screen capture, it all appears fine.
Left side of screen is the affected. And no, its not a condensation issue.
Also, i can see some lines when i start up the computer. On the grey screen portion of the start up.
I dont know what it can be anymore. I know this is a long post, but i had to explain all what happened to it.
Any help would be great.
Thanks

You might want to clean up your profile. An iMac G5 will not run Mac OS X 10.6.4!
My experience with things appearing on screen but not in a screen capture is that it is on the display itself and not involving the GPU.
I think that you have image persistence, similar to CRT burn in. It is caused by having the same image appear in the same location over long periods of time, like a Safari window always in the same location, or an iTunes window, etc. The pixels get stuck showing that image.
There are different little apps that folks have developed to get the pixels unstuck. Google LCD image persistence and you can find a number of them.
Here is one suggestion;

IMac external display problem

Hi,
I have a spare 22" 1080p tv sitting around so I tried to set it up as an external display for my 21.5" iMac. I was able to get it working (MDP to HDMI) but the resolution and color is not so great, and when I look at the external display in System Profiler it says something about it being a tv (which it is). My question is can I do anything better than what I have experienced so far? Thanks for the help,
rc
Note - I also tried running the Color Profile app that appears on the external display and while it did improve it some once I clicked on save it never seemed to stick...

Go to: System Preferences > Displays select the Color tab > uncheck "Show profiles for this display only" and try one of the RGB profiles to see if it is better for you.
Then if you are not happy with one of those..? Try Selecting, Calibrating and Saving a different Profile, other than the default one offered for that monitor.

Mail with display problems???

I have a problem displaying the header information i a correct way. There are line breaks between "from" and "subject", normaly there shouldn't be not one line break.
Does someone know how to solve this problem.

J. C.,
My suggestions were only applicable to to Rafael, and not you. You problem is likely that the Helvetica.dfont is missing, or turned off -- it is required for the Red Dot, and many other things in Mail, Safari and iChat. You were correct that it has to do with the system fonts. See:

All the best.

2 month old 21.5" iMac with 2 problems starting today.

I bought this iMac on September 14th of this year. Today it was having a hard time connecting to my wireless network. My Macbook Pro had no problems at all. I am not entirely sure that this is a computer problem because it was able to scan and find other networks in the neighbourhood, but my own that is just in the living room didn't show up at all. When it did show up it would just disappear a few minutes later.
The second issue has to do with the iMac turning off on its own. I would leave my room for about 30-40 minutes to eat or watch television, come back, and it would be off. I would have to start it up via the power button on the back. I ran the AHT thingie and it said no problems. I was wondering what I should try next before I bring this baby over to the apple store.
Thanks so much!

You have 90 days of free AppleCare phone support. This sounds like the perfect time to use it, they're open M-Saturday during normal business hours and the number is in your owners manual.

Apple sent REFURBED Imac with Drive problems vs NEW ONE i bought

I bought a BRAND new Imac from the store 3 weeks ago and right away there were signs that it WAS NOT.
The first time I turned it on, it asked me to set up Panther and I did...over and over and over again because apparently theres a notorious "infinite loop" glitch that usually occurs when someone UPDATED the system. If this was brand new, you would think that there would be no need for that.
After 4 hours, I manage to bypass it by putting in the startup disks and virtually restarting hte computer.
Then, the startup disk won't spit out. I called Apple Support and they said well, theres no way to fix it unless I haul the entire system to apple or paid an ungodly sum of money to have a technician come.
This was day 1 of owning the computer.
Day 5, it miraculous spit out the startup cd.
Other problems: now my comp won't boot camp windows. it will partition the drive and then when I put in the disc, it will say 'no installation cd found.'It runs SUPER a lot of times despite me only having MS Word open. Today, I tried to get it to spit out the CD to install a router and its stuck again.
So my question is: a) how do i get the cd out again? (I tried the Command O fix, Cmd C fix, credit card)
and b) who do I contact to yell at apple for this? I strongly believe they sent me a used product and I don't want it to be replaced with another used product. I paid $200 over a Refurb for a new computer. Theres no email and everyone on the phone seems to be from a small Asian country with no idea what I'm talking about.
c) If all else fails, I know apple users have been really successful in filing small claims suits but how would I go about doing so?

{quote} a) how do i get the cd out again?{quote}
It is probably just a bad drive. Bring it in to have it serviced like Apple had recommended.
{quote}b) who do I contact to yell at apple for this?{quote}
For what? Sounds like you received a computer with a bad optical drive which is covered under the warranty. You have absolutely no reason to yell at anyone, but the customer service number is in the box...
{quote}c) If all else fails, I know apple users have been really successful in filing small claims suits but how would I go about doing so?{quote}
Talk to an attorney, but considering you refused to have the machine serviced or exchanged you would have little chance of anyone even caring about your problem.
{quote}Theres no email and everyone on the phone seems to be from a small Asian country with no idea what I'm talking about.{quote}
Don't lie to us. There is an email with every sale that can be tracked by the customer as well as Apple. Considering the fact that you don't even know what you're talking about how do you expect someone else to respond? You claim that your machine came with Panther, however, no machine Apple has sold in the last two or more years would even be capable of running it. Any machine that would be capable of running Panther would not be able to run boot camp.
{quote}I strongly believe they sent me a used product and I don't want it to be replaced with another used product.{quote}
Absolutely nothing you provided would give me, or anyone else, a reason to believe that you received a refurbished machine. Given the fact that you refused warranty repair and are paranoid about exchanging it, I don't understand how anyone on this forum can help you.

Brand new MBP with display problems.Ghosting & Red Pixels

Bought a MacbookPro at the apple store in Santa Monica,CA as a gift for sister in law who lives inNepal. When we got to Nepal and she started the computer for the 1st time, the display was ghosting, everything that was gray or blue was red tint, & every highlight was red.Ranthe Hardware test & showed everythingis fine. Would like to exchange for a new machine, but it is so far and dont know when we coming back, any suggestions for repairs, what the problem may be?
Appreciate the help.

It looks like a graphics issue. Download gfxCardStatus and try switching graphics mode once. You might get it to work in one of the modes until you can get it repaired or exchanged.

IMac as Display problem

Hi all. I have an issue and would like to know if it can be resolved easily.
My iMac 2009 has major issues. I tried to reformat the drive and reinstall the system but the installation fails every time. I replaced the internal drive but still no installation was possible. An external drive with a system works, but the iMac is extremely slow and can take 10 minutes just to open an app. It was very slow with an internal drive when it was working anyway.
I resolved to by a Macbook Pro and use the iMac as a monitor (27 in) using a Thunderbolt cable. But it seems that without a system attached to the iMac, it keeps looking for a system and I cannot use it as a monitor.
You could say that I only need to let the external drive with a system connected to it and it will work, but is there a way to make it work without practically losing my drive? Is there a key that I could use so it stops looking for a system for example?
Thanks for any help.

New iMac With a problem

I Used Migration assistant to transfer files from my PC and now I have bunches of files on my 2 day old iMac that I don't want. Is there a way to put it back to the way it came out of the box and I'll find another way to get the files.

You are very welcome, Jan. Macs are actually very easy to work on and clean up as described, but it is always good to get someone to help out if you are uncertain. Stick around on here and ask questions, this is a great place to learn. Also, check with your Apple retail store, if there is one convenient, as they have free classes regularly scheduled to help new-to-Apple users. Classes cover a wide variety to topics so check with them often to see what they have going.

Display problem, new motherboard.

I am posting really to vent. I have a sick iMac with display problems. It's got vertical white lines and loss of colors. ChumpUSA indicates that the motherboard will need to be replaced and it's going to take four to five business days to get the part.
I purchased the iMac for a client who I encouraged to switch. They trust me and have purchased two other Macs. They are doing fine, so they aren't soured yet. It's a difficult position in which to find myself. Computers have trouble and need to be fixed, knock wood, I've had very few hardware problems in my 10+ years using Apple products.
I'm just in a bad spot with the failure of the motherboard (poor quality?) and the length of time my client is without a computer for one of his employees.
We will work around it, of course. I just don't see why it would take a week to get a part.
Any advise or words of encouragement are appreciated.

Sorted myself but will post solution in case others need it.
Remembered what I had done ages ago when looking at how to stop all recent pages appearing on a new tab.
To get new SEARCHES appearing in a new tab go to address bar and type
about:config.................ignore the Dragons
then go to browser:search:openintab and set to true

IMac display problems with gray to white gradients

My early 2006 iMac 20 has problems displaying gradients going from pure white to light gray. The web colors are #000000 to #EEEEEE (RGB 238 238 238 and 255 255 255)
My cheaper Acer and Fijutsu Siemens displays can handle this very well, but my iMac cuts the gradient prematurely and makes the gray darker. It looks as if the gradient on my iMac is a dark gray bar and a white bar, instead of a smooth gradient compared on the two other monitors.
I know the iMac doesn't have the best display for a designers need, but it can't be that 'cheap' or can it? I have tried to calibrate the display with both manual expert mode and using ColorSpyder. The latter gave me a blue/magenta colormode with beige gamma each time, so I gave that up.
The frustration is that I have use my iMac as secondary display and one of the other primary. It is not the optimal arrangement for an office environment.
Does anyone have the same problem or do they have any good advice for me as of what to do?

Thanks for all the speedy replies.
Barbara:
This was reassuring news, I have been using Spyder2express with both the bundled calibration software and another professional (and high revered) software, which name is completely lost to me right now.
In both cases, with blinds shut, lights turned off and no other interference, I got a beige/dark result from both. With a bit of flicking with the settings, I managed to produce only a sick magenta result.
Your post reassures me that it can be done, so I am going to borrow the Spyder2 again and try all over, even read myself to death on the instructions once more.
