Newly Puchased Refurb iMac Display blew; Send back or repair?

Just wanted to get some thoughts from the forum gang. I just purchased a new refurb iMac Intel Core 2 Duo white from the Apple Online Store, and it worked great...for about 2 weeks, when last night the display freaked out and then blacked out. I took it in to my local Apple Store to be repaired, and they told me I had the choice, since I just received it May 9, to have them repair it or that I could send it back to Apple for a new one. Well, a new refurbed one. I was really torn. At least with this one I know everything else worked great, and if all they have to do is put in a new display, it will be a lot easier than removing the added RAM, repacking it, mailing it back to Apple, waiting for them to receive it and send another one, and then wait all day for FedEx to deliver it.
If it had been a new computer, I wouldn't think twice about sending it back, but how do I know I wouldn't get a replacement refurb iMac with more problems? So I opted to let the Apple Store repair the one I have. As the replacement display was not in stock, I do have some time to weigh my decision. What do you all think is the better option? Thanks much.

Normally you have the 14 day timeframe to reject the Mac. Sometimes with a refurb you pay for the model and occasionally you get an Easter Egg or two. Were there any free upgrades that came with the Mac? Upgraded HD or graphics card or extra RAM?
With a brand new Mac you would not get a refurb replacement during the 14 day timeframe, you would get another brand new Mac.
Since this is a refurb, this may not be the first thing to go wrong. It could be a lemon, it happens, even with Apple. I would definitely buy the Apple Care extended warranty with this one.
Then again, replace the display and you may have the best 'puter you have ever had. One can never tell with electronics. But Apple always stands behind its product.

Send back for Repair? Heat. Firmware. RAM.

Any experienced MacBook Pro users out there who can help me with my situation?
1. Brand new 17" MacBook Pro arrives (after waiting over a month from MacMall) and I install 1GB of EdgeCorpTech RAM, run Software Update, and install Final Cut Studio 5.1 (Universal) and run Software Update again.
2. Start working and during an encode in DVD Studio my brand new expensive Mac crashes. Tried about 7 times over and over again, each time either rebooting or hard locking.
3. The heat! The area above the keys is so hot you could burn yourself. The more it works, the more it heats. I hear no fans trying to cool it down, but then they might be very quiet. (I've heard the fans in an older PowerBook, and they are really loud. Are these supposed to be similar?) I've read a lot about this issue, and thought it might be why my system was crashing. I've also read that it's a "feature" where it acts as a heat sink. When I called Apple, they asked me a bunch of questions like they were taking a police report, and told me I needed to send it in for repair, but I would like to avoid doing that. If it runs this hot and the surface is a heat sink above the keys, I guess I'll just put up with it; when you're cooking you keep your hands off the frying pan! Think different, right?
4. I removed the 1GB of Edge RAM and no more crashes. It successfully encoded and it seems to be working, but the heat issue remains. I'm sending in the RAM for exchange. (Now I'm reading that someone else had this issue and that it may be the system having 2GB installed, regardless of the brand. I'll be able to test this in a few days when I get the new RAM.)
5. I puchased this Mac for a job, so I really don't want to be without it since I lost money waiting for it to arrive. Not only would I have received my order weeks ago had I ordered it from Apple, but Apple tells me they would have sent me a new one since I'm having this type of issue. Since I purchased it from MacMall, however, I was told I needed to contact them about it. I did, and MacMall is horrible. They tell me they have a "no return policy" on this. So they charge me brand-new price for a system that may need to be refirbished? They told me I needed to contact Apple. That's the last time I order from MacMall.
6. Apple sends me a shipping box to send it back for repair. I will be without it for 1-2 weeks. They also tell me I can go in and speak to a tech at one of their retail stores. I call the store to see if there's a tech available and they tell me I would need to come in to find out. Sheesh.
7. I'm hearing that a firmware or SMC update may do the trick. I have the following now:
Boot ROM Version: MBP12.0061.B00
SMC Version: 1.5f8
I called Apple support back 3 times and spoke to 3 different people. So far no one at Apple tech support has been able to tell me if I have the latest version.
To recap, my questions are:
Is this kind of heat normal?
Do I have the latest firmware?
Should I have it repaired?
If so, should I send it in or take it to the Apple Store?
Any help would be appreciated. Thanks!
MacBook Pro 17" Mac OS X (10.4.6)

Thanks, people.
I'm worried about sending it back not just because I'll be without it but also because I've read horror stories about how they ding it up during repairs.
Do firmware updates go through Software Update? I've heard they don't, and if there's a new version my Software Update is not finding one. I can't find any info on the Apple site, and Apple Support reps don't know either.
If the heat is more of an issue with me than it is with the system, I can put up with it. Since the Apple Support reps can't even tell me what the latest firmware version is, perhaps they don't really know how hot the 17" MacBook Pro is supposed to run..?
When I ran the hardware test before, I didn't notice the fans running at full blast. I usually notice that sort of thing. Maybe my fans are not working. I will run the test again and make sure to pay more attention. Does anyone know if the fans on the 17" run more softly than the others? Also, to notice this, would I need to run the full test or just the quick one? I'll try both...
Thanks again for all your help and advice...

2008 iMac, display not coming back after sleep, requiring SMC reset and more.

I have a 24" 2008 iMac that's recently started giving me migranes starting a couple weeks ago. It's the kids' shared computer in the bonus room, and one of them comes in and tells me it's not working. I go in, and it seems like it's off, but I can hear the fans going. Won't respond to mouse, keyboard, even hitting the power button that usually pops something up warning that I'm about to shut it down with people still logged in. So I hold the power button down to force it off, wait a minute, and turn it back on. I hear the superdrive sounding like it's trying to load a disc, but there's nothing in there . . . keeps making that noise again and again. No startup chime, no display, nothing, just the superdrive sound. Can't get it to boot. I come to the support site and go through resetting the SMC - unplugging it for 15 seconds. That at least takes care of the superdrive sound, and I get the startup chime, but no video.
I go a step further, unplugging it and plugging it back in while holding the power button down for 10 sec. When I hit the power button after that, it comes on, display nice and bright, but the fans are now running full speed. Another article tells me to reset the SMC for that, which I do, and now the fans are working properly and the system is working again.
Problem is, I wind up having to go through this whole thing every other day. If I follow the steps of unplugging it, holding the power button down while I plug it back in, turning it on and booting up, shutting down and resetting the SMC to make the fans slow down, it will work. But it's random as to when it happens, and I'd really like to know why it could be happening and what I can do to fix it for good and not have to go through the whole thing to get it back up and running. Is it simply on its last legs? Do I need to restore the OS (Snow Leopard upgrade)? Do I need to take it to the Genius Bar and pay them to look at it and diagnose it, and God knows how much to fix?
Or, do I recycle it and just bite the bullet and get a new one? Any thoughts would be greatly appreciated, thanks!

the first thing to try is resetting the pram/nvram

if this doesnt work it could be a loose display cable.

IMac display doesn't turn back on after sleep

This is a new problem on my two-year old iMac, and didn't happen before. What is happening with my iMac is that when it goes to sleep and the display turns off, the display doesn't turn back on when I move the mouse, press the keys or the power button.
It happens only after around 12 hours or so of inactivity, it seems. I have to reboot the iMac to force the display to turn back on. I think it is display issue, not the computer lockup because I checked which logs were written in /var/log - system.log was being written until I rebooted the iMac. However, I didn't see any information in there around the same time that I tried to turn the iMac back on.
Any ideas on how to debug the issue.

Hi dailyjoe
1. Reset your SMC exactly as instructed in the following article:
http://support.apple.com/kb/HT1543
2. It would be normal for you to have to startup your iMac if it lost power while in sleep mode, look at the box "Start up automatically after a power failure" in the Energy Saver preference.
I have always left the box for "Start up automatically after a power failure" unchecked and do occasionally find the iMac is shutdown because the power has gone off. I would suggest leaving the box unchecked, it's better than having the iMac going off & restarting multiple times if you are having bad weather or power issues.

The internet pages don't display properly I'm using osx10.3.3, yahoo for example asks me to update, but I cant find out how to as the apple store just keeps sending back to the same page with no down load option...do i need to up date or is it just my mac

What Mac model do you have? You might be able to upgrade the OS to Tiger 10.4 or Leopard 10.5.
Even browsers for Tiger 10.4 will get the update message.
You could try a newer browser than Safari, which is obsolete, by downloading Firefox v2.0.0.20 at http://www.oldapps.com/mac/firefox.php

Recently while using my iMac the display will just cut off but the machine is still running and I have to press the power button to get the display to cut back on. What is causing this?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Intel imac display glitch and involuntary restart

Just want to know if anyone else has experienced this specific problem, there are plenty of complaints about intel imac displays but I can't be bothered to sift through them all trying to find a match for my problem.
A couple of months ago I was watching a video in quicktime and noticed that my screen was glitching and flashing fragmented diagonal lines - like a commodore 64 loading type thing. Then the spinning-ball came up and a force quit didn't do anything so I had to force shut down. I started up and it occured again. Then the screen went blank/black, but still lit up, and restarted without me doing anything. It also got stuck during start up the second time this occured. I panicked and ran out to buy a 500GB external drive, backed up all of my work and then re-installed mac osx from disk, archive and install job. This seemed to sort it and for the following two months it seemed OK. No sign of any problems.
Since then I have updated from 10.4.7 to 10.4.10 (which I have suspicion that it screwed the firmware in my motu 828 firewire audio interface, costing me a £130 repair - but that's another painful story).
It happened again tonight (the screen thing, not the motu). And the ball came up and I couldn't do anything. Force shut down, restart - screen glitching again. Then I had 2 unexpected restarts, one getting stuck in startup. Then a successful startup but accompanied by the glitchy graphics, mainly red/pink pixellated diagonal lines flickering in and out. I ran a disk first aid - no problems. Did a disk permission repair. Shut down and ran a hardware test, the first few minutes of the test the screen was still at it but then stopped glitching, hardware test found no errors (it was an extended test too). Now I'm back on it and it's all OK.
Any suggestions/similar stories?
When it occured 2 months ago I had the original ram that came with the imac. Now I have 2x1GB sticks of crucial ram.

That's it! Well, that's what I have. Unfortunately, I don't know about the cause, but I don't ever recall having it prior to an update going back about a year ago. I recall an update, and that update being immediately followed by some sort of Apple Graphics something-or-other. I feel pretty certain that's when I first noticed this. I just had my LCD replaced for another reason, but I think you'll agree, it's not an LCD issue. In my case, browser activity, scrolling up or down in a page, seems to be the most common trigger. I've also seen "pieces" of the torn page, on the screen when minimizing the browser to the dock (usually Firefox, but I think I've seen it with Opera and Safari too). Is there a way to find update packages installed somewhere? I'd know it if I saw it, and I'd definitely try removing that suspect package/update.

My 20" 2.16 GHz Intel Core 2 Duo had become almost useless due to freezes and crashes- with NO crash reports in the logs.
They were often preceeded by video glitches, so I assumed it was a bad video card- unfortunately soldered to mother board.
Apparently, from forum postings, this is not an uncommon problem. The computer would run longer if the day was cooler, but rarely more than 10 minutes, so I suspected it was aggravated by heat.
Then I found this post from Bodomann on an Apple Support forum:
"Following up on my previous posting regarding my son's late model 2006 iMac that required a $900 logic board replacement:
Turns out the problem is apparently related to a bad CPU temp sensor. I installed 'iMac Fan Control' (Google it) which reported the CPU temp always at 32 degrees Fahrenheit (obviously incorrect). The same software allowed me to adjust the CPU fan manually. After multiple trials I set the CPU speed to 2800RPM after which the system would run forever - never freezing with the dreaded grey box 'reboot me' screen. I tried several times reverting the software to default speeds and the system would always crash within 10 minutes. "
I downloaded free Fan Control 1.2 for Imac from Derman Enterprises (they have an Intel iMac and a Mac Book/Pro version). It installs as a system preferences control panel. I cranked up all three fan speeds. The fans sped up noticeably. Horizontal lines have gone from screen (so far), no color artifacts and no crashes yet. I may have a real computer back! Hope Apple checks this out-
The control panel also gives the temps sensors are reporting at the CPU, hard drive and DVD drive. The CPU sensor reports the CPU temp as 32 degrees F- which is clearly wrong, unless Apple has been installing little refrigerators inside.
So thanks to Bodomann for posting- Hats off and three cheers to Derman and Cristoph for source code.

IMac - Display doesn´t work after restart

My iMac 21 Display doesn´t work after restart. If I turn it off and 1 hour later I want use it again the iMac shows the white screen with the mac logo and then the display goes off. I connected an external display to check if the iMac was ON and with the external display I can login and do everything but the iMac Display doesn´t work .
If I turn it off and wait 3 or 4 hours and then turn it back on the display works OK.
This is very strange behavior I have spent hours and hours trying to fine the solution or a similar issue but nothing so I am looking help here at apple.com
BTW When I bougth the iMac 21 there were some spots over the display so the display was replaced by the provider. The warranty has expired by now.

To tell you the truth, I don't know if they have to repalce the LCD panel or what they do for a bad backlight. In this reality of block or assembly replacement it probably involves repalcing the panel and not the backlight component. Don't know what it would cost. You'd have to ask that of a service center.

Imac Display not working at all

I'm using the latest release of Leopard on my iMac that is less than a couple of months old and the display just went off, totally black and I cannot get it back on.
I have tried:
- Unplugging all peripherals and rebooting
- Resetting the PRAM (http://docs.info.apple.com/article.html?artnum=2238)
- Resetting the System Management Controller (http://docs.info.apple.com/article.html?artnum=303446)
What is strange is that I left the machine running for a couple of hours and went back to it, waking it from sleep by touching the keyboard and the display actually came back on and I thought it was miraculously fixed. However, as soon as I touched the mouse the display went off again and I haven't been able to get it back.
I can hear the machine when it boots and I know it's starting ok because I can hear the noises when I turn the volume up and down using the keyboard. Because the display did come back, although extremely briefly, I reckon it has to be a software problem.
What's really frustrating is that I haven't got screen sharing turned on and I'm writing this from my MacBook which I could use to try to diagnose the problem.
I have figured out all the keyboard commands I need to bring up the screen sharing dialogue but I don't know what the keyboard command is to tick a check box!
Any help would be greatly appreciated.
Paul.

Luckily mine is still under warranty, but it is still away being repaired.
Strangely I discovered that it would still run an external monitor (but i couldn't set it to be primary) so the problem can't be with the graphics card.
This whole experience (combined with numerous separate issues I have had with Leopard) has certainly tainted my view of Apple.

27" imac display acting as two displays

Can seem to find the answer to this, results lead to howtos on a dual monitor setup.
I'd like to know if I get a 27" imac can I have the monitor act as a dual screen setup. Essentially, I would like my windows to load and act the way they do given my dual screen setup that I currently have with my macbook pro.
I know I can resize windows and get it to mimic a dual monitor setup, sort of, but I'm trying to avoid this every time I open something new.
Does anyone know if is this is something that I can do easily with expose and spaces?
Thanks

Welcome to the Apple Discussions!
If I understand your question correctly then yes, the iMac display can be toggled back and forth between the two computers with F2. When the iMac's display is being used by the PC it is in Target Display Mode. The issue is that the iMac can only use mini-DisplayPort input from an external video source. So you would need a PC with m-DP output or a very expensive converter to convert your PC's current video output to m-DP. Then you connect the converter to the iMac with a simple m-DP to m-DP cable. These converters which are fairly new start at about US$150.

New iMac display on/off

Does the new iMac have an on/off button for the display that is separate from the on/off power button for the iMac itself?
It would be nice to have the ability to turn off the display, when not in use, without having to powering down the iMac.

Sleeping the entire machine is one thing. Sleeping the display is a separate issue.
It seems there's currently no way to PERMANENTLY turn off the display backlight on an iMac. Setting a display time-out in the energy-saver settings or Ctrl-Shift-eject is supposed turn off the backlight, but if you have applications running on the machine, the display will turn itself back on again after a few seconds. (Try sleeping in a room with an iMac display on. Even displaying a black jpeg with the brightness turned down, you'll need to physically cover the screen!) The backlight will normally power down properly when there's nothing running on the machine, but if the machine weren't doing anything, I'd just sleep the whole machine, not just the display!! I want to sleep just the display/backlight when there are time-consuming applications running in the background, i.e., if the machine is encoding, running backups, syncing with cloud/server drives, etc.
This thread shows many other people having the same problem:

It seems this has been a problem for well over a year and I've not even seen Apple acknowledge the issue. IMHO, not being able to leave applications running with the backlight turned off is a critical design flaw. If I'd known this in advance, I'd have bought a Windows PC Now regretting my iMac purchase...

2010 imac display went black, but hard drive still working

Does anyone have an idea as to why the screen is black? Was on it about an hour ago with no problem. Have turned it off and back on, can hear it, but no matter what screen stays black.

Lolo55,
Thank you for visiting Apple Support Communities.
I understand that your iMac display shows a blank screen. Here is the best troubleshooting resource to go through when experiencing these symptoms.

IMac Display stretched and out of focus

My iMac display is not right. It is slightly enlarged and out of focus. I have already tried the display settings and holding the control key and scrolling down. I also tried restarting. Nothing is working. Last night I tried configuring my router for wireless. I supposedly made it secure with a password, which I had to use to connect to my network. The screen thing happened after that. This morning I checked the connection again and the little lock icon was no longer there. Could the two be related? Please help! I am obviously not very apt with computers, but I'm trying.

This resolved my issues:
Preferrences > Accessibility > Zoom
then, uncheck Zoom and uncheck Zoom follows keboard focus.
Wait a few minutes. You can rechec them again but it won't go back to the stretched and out of focus look. I don't know why.
