Imac Replace Screen/Screen Failure?

Hi All
I'm thinking of getting the 21.5 imac but I have a bit of a concern about it since it's an all-in-one
If the screen/monitor fails, is the entire imac stuffed? So I have to get the entire imac replaced??
Just out of curiosity, how long would an imac last if I'm just using it for light use (ie no gaming). Do you know anyone who has had their screen fail?
Just want to check because I'm a bit concerned about it, before i make my purchase.
Thanks all apple-people.

Hi,
I've had my mac for about 5 years. I've had to replace the hard drive but I've never had the screen fail so I can't answer that part.
I've found the service and warantee's on mac fantastic

IMac Screen Failure

Hey,
I was just wondering if any of you are experiencing screen failures as noted in the link below? If so, is it the aluminum iMacs, or is it the white ones?

Thanks!!

Hi autiger
Which iMac do you have and are you having any display issues?
I don't believe it can be jinxed, so I'll do a little bragging here. My 17" Early Core Duo w/Apple Care purchased Jan. 21 2006 is great and has no gradient light/dark, no dead pixels and only a very very small backlight bleed. The sRGB and Adobe RGB (1998) profiles were OK, but the display seamed a little washed out. After more than a few tries, and some good advice from Barbara B and others here I was able to set a new profile that is much richer than any of the factory supplied profiles.
All display manufactures and computer system will have there share of issues, some more that others. I have had more than a few Apple's over the last 20+ years without a single hardware problem. I do have to admit though, that with the all-in-one Intel I bought Apple Care for the first time ever???

Replacement screen for iMac pre-calibrated?

I just received a new late 2013 iMac. There is a scratch on the screen and the reseller is saying they will replace the screen (a new machine will take ages they tell me).
If I get the screen replaced, will the replacement screen come pre-calibrated? I have read that Apple calibrate them at the factory - is this done for the screen component itself or done when the whole computer is assembled?
I don't want to replace the screen if it's not going to be as well calibrated.
Thanks!

The DEFINITIVE iMac 20" Screen Dimming Thread

Ok, so I've been going through this board for a while now, looking for answers to why the top half of my iMac 20" screen goes dim, after about 5-10 minutes of use. (from starting up or waking from sleep)
I have read several threads in this forum from other people who seem to be experiencing the same issue, however I have not been able to find a SOLUTION.
Do I need to send this thing away for repair? Am I going to have to spend $800 on a new LCD? I am starting to get a little annoyed when this happens. When I first received my iMac it would do it once a month maybe, however in the last 2-3 weeks it has started to go dimmer at the top half of the screen ALL THE TIME.
Could it possibly have anything to do with the sleep light firmware fix? or the fact that I have installed 2 1gb sticks of ram?
I need an answer please.

Hi again, Ryan,
The most probable cause of your problems, I would think, would be an inverter board failure (which I think falls outside the extended repair program, but check with Apple first) . The inverter board appears as a user replaceable part in the User Replaceable Parts listing
The relevant instructions for replacement of this part appear HERE .

Upgraded to Yosemite and can no longer remote into my work iMac through screen sharing- it is turned on in settings?

My screen sharing functionality did not show up in the dock with an updated icon. It had a question mark- shows my connections but nothing works, I did make sure screen sharing is on and also connected to VPN. Once I tried to launch screen sharing nothing happens. Such an elegant solution in Mavericks not does not work. Ugh. Help!

This is the post that got me set up- I too am running an older version at work vs. Yosemite. As soon as I followed is advice everything worked.

I believe the location of the "Screen Sharing" app has changed, which explains why if you had it in the dock it has been replaced by a ?
Don't forget you can launch screen sharing (once your VPN connection is up) by typing in the Safari destination slot vnc://remotemachinename:portnumber (omit the :port number if you are using the default VNC port, 5900). This should launch Screen Sharing and put its icon in the dock. You can drag the Screen Sharing icon to the left of your dock and it will hopefully remain there after you exit Screen Sharing, or you can right-click on the icon when it's running and select Options->Show in Finder to find out its new location and drag its icon to the permanent entries in your dock.
Hope this helps; worked for me.

Ipad screen failure

My bought my Ipad 15 months ago (Ipad New) and has recently started a tendency for the screen to suddenly flicker, a bit like an old TV which loses vertical hold only much more rapid. I can turn the device off by holding down the usual power down buttons and things start off again normally but the problem is appearing with increasing frequency. This problem has appeared since I upgraded to the new IOS 7 about 10 days ago. Does anyone have a solution to this other than replacement?

My iPad does this sometimes, have you dropped it before?
Anyway, to get rid of this screen failure you take your iPad case off if you have one on and smack the back of your iPad.
It may seen that you're doing harm but you're actually fixing the glitch!

Screen has lines running through it, is it worth replacing screen?

Screen has lines funning through it, is it worth replacing screen on 2009 iMac?

What do you mean by lines running through it? There have been users with vertical lines, sometimes blue, or yellow, or pink, or combinations. Those have all turned out to be a bad graphics unit chip that the Apple store techs were able to remove and replace without replacing the entire logic board.
Take it to an Apple store genius bar and have the techs test and advise on how to resolve this.

Hi Brett L,
thank you for the coordination of this helpful thread. Are you Apple? If yes, please allow me to ask you three questions:
1) The Display Firmware stopped for over 90% the flicker issue, but what has this Firmware changed exactly?
2) Is Apple preparing a fix for the yellow tinge?
3) When will it be save to buy a new iMac?
Thank you for your efforts.
Hello Citrus.
Excellent questions.
I hope that Apple will authorize Brett L. to provide us with some clear, honest answers to them . . . although, as I pointed out before, it would seem by the latest messages that have been posted in this thread -- that is, the *original thread* -- that through their actions, Apple has already provided us with their answer -- and solution -- to the yellow tinge issue; and that is the replacement of the LCD panel.
As to what the most recent display firmware update did, I am doubtful that Apple will allow Brett to reveal that kind of information, but we can be hopeful.
As far as when it will be safe to purchase a new iMac, I seriously doubt that Apple will say anything which would suggest that it is not safe to purchase a new iMac now. What company is going to say "Don't buy our product now. It's not safe"?
For my part, I have now contacted Apple regarding the issues that I am having with my 27" iMac, and I will wait over the next few days to see how things play out. Based on the testimonies of others here, I don't expect Apple to disappoint. I have the confidence that they want to leave me a satisfied customer who will continue to purchase their products in the future.

IMac G5 Screen Cracked!

My iMac G5 screen was cracked when my son threw a toy at it while throwing a fit. Some of the old background is still visible, but most of the screen is dominated by wierd colors and designs. Is it possible to get this fixed? If so, how do I go about doing it?
iMac G5

Hi,
I don't know if it is going to be cost effective for you to have your screen replaced. I've seen some posts here at the forum quoting prices in the $600+ range.
You might want to call Apple Service, I'm sure they have a standard price for replacing display. I would try to figure out how you can back up your data. I believe you can also add a 'second monitor' but you would have to do all the configs and if your screen isn't working that's nearly impossible...

Kernel Panic & Screen Failures

I've just had two identical failures in one day on two separate Powerbook G4's running Tiger. There was a kernel panic while playing World of Warcraft, and now the computers' screens cannot be activated. I hear the hard drives spinning, but the screen never comes on. The Apple light on the back of the lid does not light up, the sleep light does not work - in fact, the sleep function does not seem to kick in when the lid is closed.
My wife's G4 failed yesterday. She was playing WoW, and she reported several kernel panics. Finally her machine failed to boot correctly at all.
Today, I tried to get it working, employing all the usual methods. I suspected some type of hardware failure. We gave up, she pulled out her old iBook and I played a little WoW on my G4. While simply checking my in-game mail, I got a freeze/kernel panic. I rebooted and the screen stayed blank - precisely the same symptoms as hers.
These are identical 12" Powerbook G4 1.3 GHz models with 867 RAM (factory-installed) in each. We're on an Airport network and in separate rooms, and not plugged into the same power source.
I reset PRAM, reset the Power Manager - no luck.
I get startup chimes (even the second chime for the PRAM reset) and I can hear the drive working. The system is coming up, but the screens and lights are not working for some reason.
I can boot the machines into Target Disk mode and access the hard drives via this iBook, so the system seems intact. On the affected machines, I can press the Volume up/down keys and hear the audio sound cues. Brightness keys have no effect.
It would really seem to be a Power Manager issue, as if no power is reaching the screen or anything in the lid. I reset the Power manager to no avail....
Two screen failures on identical machines under the same circumstances less than 12 hours apart? That's one heck of a coincidence... is anyone aware of a known issue similar to this?
Powerbook G4 12" Mac OS X (10.4.6)

No, this is not it.
I too today expienced a Kernel Panic while playing WoW. This only happened before about 4 or 5 freezes within the game which ended up having to be reset with the powerbutton pressed for 10secs.
This happened, as I said, about 4 or 5 times, while connected to external monitor and without. This has only ever happened to me today. I reinstalled WoW. Nothing. I thought it was a temperature overheat so monitored the temperature with iPulse, it heated to 55.3 degrees celcius, one fan kicked in and it crashed.
I then used GioFX's HD 3d screensaver.
The computer crashed within minutes. What causes these crashes?! It is something to do with the GPU's 3d rendering, but I can't see why it happened today... the only thing I can think of is heat damage, it has been hot the past few days (30 degrees and more ambient temperature) and the laptop's fans have been working full tilt for 2, 3 hours and more while I play.
I am lucky, as my PB is able to be used (as long as no graphics are intense) but it is, in effect broken.
I need a response quickly, my guarantee with the seller is running out soon, do I need a GPU replacement or don't I?
This happened while playing World Of Warcraft 1.11.2(5464) and attached to an external monitor, keyboard and mouse.

Macbook Air 11" 2012 screen failure?

Wondering how many others have had problems with screen failure on this particular model? I purchased march of 2012. I read elswhere that they were having issues with displays that were not Samsung brand. I just had to pay to replace at 16 months; 6 months of of which no use. I am not a high user of machine. I was really disappointed with the attitude of "oh well you did not buy the extended warranty?"

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

21.5 inch iMac yellow screen issue

I have a late 2012 iMac (21.5inch). I thought 21.5 models were immune to this issue, but I noticed bottom half of the screen is showing some yellow tint compared to upper half. I thought it was due to the angle of the screen and lighting in my room but that changed when I put my MacBook pro right next to my iMac. Compared to my mid 2009 MacBook Pro, the iMac's screen has a definite yellower time to it..
How much will it cost to replace the screen to eliminate the yellow tint? Please, no replies about taking my iMac to Apple store or calling them. I've already called several different Apple stores, and they have no idea. And please, no Applecare answers or "expensive" answers. I just want exact numbers.

The in-store inspection, product specialist or in-house expert, then technical testing to diagnose the exact cause of the issue, then if done in-house, a repair sequence initiated with an open estimate on what replacement parts would actually be needed, could alter the original best-guess somewhat.
A simple backlight or inverter issue may be all that is causing the symptom. Nobody can simply give you a base price of one size fits all. They will not just 'replace a display' since the panel is more than just one part. If a voltage variation is the cause of partial tint or backlight color, then that will be part of the inspection and diagnosis; this may be in a shop for weeks.
Please stick to one question on the same topic
https://discussions.apple.com/thread/5919757?tstart=0
You appear to have an issue with Apple, so there are
a few good links to their main web site. You can go
and Locate an authorized service nearby, contact an
Apple authorized representative, etc, there. We who
reply here have no direct connection, nor do we have
any authority, cannot cite prices or give quotes, etc.
And our time is our own, individually. We're not Apple.
You will have to contact Apple. You have a computer.
I will not do that for you, from my residence, half a
world away where I have no more access to a Store
than a moose, or a ptarmigan, outside my door.
Good luck.
