IMac (Late 2013) screen display won't turn on [RESOLVED].

I just fixed the problem of my iMac screen not starting after calling AppleCare and thought I'll share the solution here as I could find no answer relating to this model of iMac, and the memory reset solution (see below) appears to have been archived by Apple. At the time of writing this, I am running OSX10.10.1 (Yosemite). The advice I was given is as follows.
Turn off your Mac by holding the power button for a few seconds to cut the power.
Removes all cables, including the power cable, USB cables, thunderport cable, everything. Also remove any dongles plugged into the iMac or into any other devices, I think an inactive wireless mouse dongle plugged into my USB keyboard caused the problem for me. Then plug in the keyboard and power cable and power up. If that doesn't work, turn off again and proceed as follows:
With one hand on the keyboard, at the same time hold down Command-Option(Alt)-P-R. With those four keys held down, use the other hand to press power button, keep those four keys held down for maybe 30 seconds. The computer should then start and restart a few times. This process resets NVRAM and/or PRAM (cached memory), I'm not sure which.
If this does not work, repeat but hold down Command+R instead to put your iMac into recovery mode. With any luck, it will now start up the display and run OSX Utilities from which you can restore, reinstall, and a few other things, but before you do, go to the Apple menu (top left) and choose instead to do a normal restart. In my experience, it then started up as normal and now works fine.
If none of the above works for you, then you probably have a hardware problem. If you have AppleCare take it to your nearest Apple Store (with your serial number, found on the box) or they can collect it and it will take about ten days. If you don't have AppleCare, take it to an Apple Store and expect a bill to pay.

sgmcb,
It looks like you've covered everything you need to do. It could be any number of things, but logic board seems the most likely. Not a cheap repair.
Don't take my word for this. Bring your MBP to your local Apple Store/Genius Bar and have them take a look at it. They won't repair anything, but they might be eliminate a few possibilities.
I just hope you post the results of your visit, in case others have a similar problem in the future!

MacBook Pro (Late 2008) Screen Backlight won't turn on

Yesterday, I pulled out my MBP and started it up. The screen was "black," and at first I thought that it was totally dead, but a closer inspection revealed that the display was working, but the backlight wasn't turning on. I restarted, and the backlight came up to half brightness (even though the brightness adjustment buttons would say it was at full). A second restart would bring it up to full brightness, and it would run fine from there (unless it had to shut down again). This double-restart fix worked for about a day.
Finally, it gave out. (The last thing I did before it totally died was turn down the brightness; when I got to about 4 bars, the backlight totally turned off and stayed that way.)
I've tried restarting about 50 times, resetting PRAM, and resetting the SMC. So far, none of it has made a bit of difference. The computer is running fine (I can see the screen if I point a flashlight at it), but the backlight remains definitively off.
This computer has run pretty smoothly since I got it; I haven't had any problems with Lion since it installed, and the only thing that I did between the last time I shut it down and discovering this problem was go through airport security (which I've done many times before with this computer in tow).
If anyone has had a similar problem, or a solution, I would love to hear it.

IMac late 2006 screen won't turn on

Hey everyone. I have a 24" Intel iMac that I bought in December of '06 and I'm trying to figure out if it can be fixed. I powered it up one day and the screen just won't turn on. I can hear the fans and drives, but no screen or startup chime. The white light on the front of it lights up and stays solid.
I asked some people I know and they seem to think it's the logic board. If that's the case then I'm probably just going to be stuck with a giant paperweight because it looks expensive to replace. Just looking to see if anyone has any input on it! Thanks!

Hi Joel, see if it will Safe BVoot, holding SHIFT key at bootup.
Also, once booted take a flashhlight at several angles close to the screen & see if you cant detect a faint Desktop.

IMac Late 2013 - video card and display totally glitches

HI.
Today, something strange is happened.
Looks like the video or display in my iMac Late 2013 is totally broken. I don't know what to do now.
Teh screen is always blinking, glitch and unresponsive. Impossible to use the mouse. I can see partially only 10% of the screen with a distortion from the top of the screen..... It's annoying. imac is almost new, I've bought it and started use it from the January 2014.
The problem is - that in my country (Belarus) there are no any official apple service...
as I understood - need to replace gpu, but gpu is an Intel Iris Pro. And I guess replacement will touch all the board.
such a problem... I hope there is a way to fix somehow?
A Little bit details:
iMac was not overheated. there was not any damages or something else. iMac is standing on the table and used maybe for a 5-8 hours in week. Without any hard load (graphic load). So this is double strange for me. Looks like factory defect or something like this.
Im very upset.

Thanks for the reply!
I've tried to unplug everything (before was plugged only a4tech mouse and HP printer), and reboot the system. Nothing helps . i've performed reboot about 10 times. Also I've tried to reset SMC (unplug power cord for 15 sec, then plug 5 sec after, cmd opt p r) so sad. I can't use apple service in my country because of lack of service at all, only unofficial... Anyway thanks for replies... I will try to find the way to transport iMac to the nearest country with an apple service.... So sad, it was never happened with me, first critical issue with an apple device.

My phone keeps displaying a white screen with the apple, then occasionally flicks to a blue screen, but won't turn on! HELP!!

My phone keeps displaying a white screen with the apple, then occasionally flicks to a blue screen, but won't turn on! HELP!! I have had it on charge all day and have tried plugging it in to my computer to sync.

Restore your software using iTunes.
Turn your device off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your device and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a device in recovery mode. Now you can restore to factory settings.
You should be able to restore your backup file after this procedure. If the problem comes back, you either have corruption in your backup file, or a serious hardware problem that should be looked at by a tech at the Genius Bar (make an appointment first).

Imac late 2013 freeze/crash

Hello, I bumped a crash a few hours ago:
I let my iMac Late 2013 i5, baseline model but with SSD, run overnight because I was running a MATLAB program. However, this moring, I noticed the system was unresponsive (I couldn't get the screen turned on, so I had to manually reset by holding several seconds the power button). This is my first crash, the iMac has been super stable before.
Below, I post some lines of the log extract from the console, just before the latest boot-up (after the crash).
I was wondering whether this could be due to MATLAB? Since I was running quite a heavy script that used a lot of RAM as the virtual memory indicated 14-16 gb RAM while this iMac only has physically 8gb RAM. Maybe, somewhere the RAM usage went unexpectedly upwards and the iMac couldn't cope anymore? I wouldn't know.
I was hoping someone could find the cause? Many thanks already.

Visit The XLab FAQs and read the FAQ on diagnosing kernel panics.
You state it panics over and over again. Are these at regular times or randomly? What are you doing when a panic occurs? What do you see in the Console log at the time of the panic?
Panics are generally hardware related. They can be very basic such as defective memory. You can try removing both memory modules, then testing each in both slots individually to see if panics occur.

Macbook (2.1Ghz white 2008 model) display won't turn on during start-up

hi all,
my problem is pretty simple.
Sometimes, after having used an external display with my Macbook (using the Apple Mini DVI > DVI adaptor: http://store.apple.com/au/product/M9321G/B?mco=MTY3ODQ5OTY ) the Macbook's own display won't power on during the next boot-up. I can hear the hard-disk start up, and the system boot, and I'm even able to navigate my way into the user login and shut the computer down (all via the keyboard). So the computer is definitely powering up (and in a seemingly normal way), but the display isn't.
For example, last night I was using an external display with my Macbook. This morning I plug the display back into my Mac Pro, then power-up my Macbook. But the Macbook's display won't turn on. It's as though it thinks the external display is still plugged-in. I know, that if I re-connect the external display, the Macbook's login page is displayed, but only on the external screen.
The problem only arose after I started using this particular external display (a cheap 22" BenQ, model G2222HDL 'senseye 3'). I wouldn't normally use the display with my Macbook, but my Mac Pro has a **really** noisy optical drive (CD/DVD), which makes watching films pretty unbearable (if you're into sound anyway, which I am).... so until I get my Mac Pro's drive sorted (when I have a few spare days when I won't be needing it), I'll have to continue using my external display with my Macbook to watch films.
My Macbook's specs are as follows:
2.1Ghz Intel Core 2 Duo Macbook (2008 model - I think, maybe 2009?)
4Gb RAM
Running OS X 10.5.8
Are there any known display issues with these models of Macbook? Or are there any software/firmware updates that address any display issues?
In general, I don't update the software/firmware unless I need to, or unless something doesn't seem to be working properly.
However, I've just checked Software Update, and noticed there is an SMC firmware update (1.4). So I might give that a go and see if the problem persists.
However, the problem is intermittant, and kind of unpredicatable, so I might not know for a while if it solves the problem or not.
Has anyone else had a similar problems?
Alternatively, is there a possibility there is some kind of virus or file-corruption causing this problem?
My girlfriend has a similar model of Macbook (which she's never had any problems with). Recently I moved a whole bunch of files from my Macbook to hers, and she noticed that hers had a similar issue starting up, where the display failed to turn on.... so it seems like
a) it might be a common-ish problem in this model of Macbook
or
b) perhaps I've got some kind of virus on mine?
I've been using Macs for about 15 years (yet, I don't consider myself a computer expert, when it comes to the technical details). In those 15 years, viruses have never really been a concern to me, as I've never really thought they were much threat to Macs. However, I guess, as Macs get increasingly more popular, there's a possibility people will write more Mac-specific viruses...?
Anyway, I'm open to suggestions : )
Regards,
Sam
PS I've tried:
-re-starting the computer multiple times (which sometimes works, but usually doesn't).
-re-setting the SMC (which usually works, but not always)
-plugging/un-plugging the external display to try and jog the computer into noticing it isn't connected (which doesn't work)

let me ellaborate on this part:
"b) perhaps I've got some kind of virus on mine?"
I mean, " perhaps I've got some kind of virus on mine, and I've passed it on to hers?"

How to fix the mouse and keyboard freezing when installing Windows 7 on 27' iMac late 2013?

Hi, I have a question for u guys who can solve this.
I recently bought the new 27' iMac late 2013, and I installed some softwares and used it for few days.
Before I bought this I used the 15' Macbook Pro Retina, I installed Windows 7 Home Premium 64 bit, and I used the Windows for gaming.
So back to my question.
So I bought the new iMac and I was tying to install Windows 7 Home Premium 64 bit (with the same CD).
After dividing the partition, and other stuff, the iMac rebooted and I hold down the option (alt) key. I choose the Windows CD, and it said it is "getting ready to install Windows". I let it load, and the blue screen where you choose the language, time/location and keyboard input popped up. At the bottom right corner (at the same page), there is a button that said "Next (N)" which u need to click it to go to the next step. I was moving my mouse to click the button, but I realized that my mouse and keyboard was frozen. I tried both wireless and wired mouse and keyboard but they didn't work. There was nothing I could do. I hold the power button, (that was the only option) and tried my mouse and keyboard on Mac OS and it worked fine.
I thought something went wrong in the CD so I bought the Windows 7 Ultimate 64 bit. The result was same. It frizzed again. (I just wast few hundred $)
Latter my friend lend me his Windows 8.1 Pro 64 bit. I tried it, and it worked, it didn't freezed on Windows 8.
The problem is I played Battlefield 4, Titan fall, and Watch Dogs, and Battlefield 4 multiplayer doesn't work on Windows 8.1. Even though when it works on Windows 8, I prefer using Windows 7.
Dose anyone knows how to fix this freezing thing?
My computer is:
27' iMac late 2013 (bought it just few days ago)
I did no upgrades when I bought it, except the graphic card.
I bought the iMac in Korean Apple Store, and my Windows CD is in Korean, can that be a problem?
Please leave a comment when u think u can solve my problem.

See -> http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf.
In addition to the Windows disc (or USB flash drive with the Windows installer) you'll need a 8GB+ flash drive.
The referenced manual - on page 3, I think, gives you a run-down of what you'll need before you begin the installation. You may also want to post any further Boot Camp questions in the Boot Camp forum -> https://discussions.apple.com/community/windows_software/boot_camp.
Good luck,

Persisting crashes with brand new iMac late-2013 27-inch (14,2)

Please help!!!
Last week I purchased the latest iMac late-2013 (14,2) 27 inch with everything top range directly from the Apple Online Store. My configuration in a nutshell is the iMac (of course) with wireless keyboard and magic mouse, attached to it through Thunderbolt a LaCie 5Big (10TB) external drive as well as a USB connected WD MyBook (2TB) for Time Machine and a USB3 connected WD MyPassport (2TB) for those files I want to keep mobile between my devices, all of this on OSX 10.9.1. Futher details on the hardware below:
Model Name:          iMac
Model Identifier:          iMac14,2
Processor Name:          Intel Core i7
Processor Speed:          3.5 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          8 MB
Memory:          32 GB
Boot ROM Version:          IM142.0118.B00
SMC Version (system):          2.15f2
My problem is that it keeps crashing... sometimes while doing some Final Cut X or Logic Pro X but other times while simply copying files between hard disks while Time Machine is running and everything else is closed... I can't figure out what the root cause or the particular event that triggers the crashes, thus they are quite unexpected and pretty abrupt - no warning signs at all.
I read in some of the threads that the 3rd party RAM may cause some problems but my 32Gb RAM came directly from Apple as configured while purchasing.
Here is the latest report my system gave me and I know some of you folks are pretty good figuring out what these messages mean. I will most likely get in touch with Apple support but before I do, I wanted to check with you geniuses before I spend hours on the phone with Apple support. Thank you in advance for any help you can provide.

Oh. You didn't 'splain that. In this case here's a suggestion for a start:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.
You may want to do a hardware test to determine if there is a hardware failure:

Can I install a Samsung 840 Pro 256GB into the new iMac late 2013?

Hi There,
1)   Can a Samsung 840 Pro 256GB SSD be installed in the new iMac late 2013 model? (My plan is to remove the existing 1TB HDD and replace with the Samsung SSD)
1.1) I have heard somewhere, even though it will fit, Apple's logic board firmware will pick up the non-apple product and render the iMac useless until original hard drive is reinstalled.
1.2) If it will work, will I loose my warranty on iMac? Note, the SSD will be installed by an Apple authorized workshop.
2)     Can 2x 2.5 sata drives be installed in the iMac?
2.1) I know the iMac only has 1x SATA and 1x PCIe slot, but can one not install a PCIe - SATA converter and also a 2x 2.5 drive bay in the place of the existing         3.5" drive?
Thanks for your assistance.
Regards,
asdutoit

I checked on the Samsung website and the 840 Pro is OSX compatible and should work in your MBP.

What cable do i need for a dual monitor iMac late 2013

Hi there
I am wondering if I can set up a dual monitor for my imac late 2013. I'm quite new to macs so bear with me. I'm a university student studying maya (digital vfx animation) and I need desperately to hve a dual set up. My mac is the 21.5inches. What cable would I need and would monitor would you recommend that would be a good match to my mac. I can afford around £150 but cheaper the better. I am a student who is also a full time disabled single mum lol so funds are scarce.
Thank you in advance for any help that you can give me.
kind regards
Kitt

You will need the mini-DisplayPort to VGA adapter cable, here.

So I have a MacBook Pro 2013. That won't turn on and won't charge.

So I have a MacBook Pro 2013. That won't turn on and won't charge. When the charger is plugged in the light remains green as if it is fully charge. Before it died the laptop still recognized the charger but wouldn't charge. And now won't turn on.

If you've a 2013 model, depending on when you purchased the machine, I would suppose that you're still under warranty or at least purchased AppleCare? Regardless, I would take the kit to your local Apple Store or an AASP and have them diagnose the computer (and, if you're still under warranty, fix the computer) and, if necessary, give you an estimate for repair.
There are all sorts of things that could be wrong - a faulty adapter, bad cabling, even the entire electrical circuitry may have gone bad.
You won't know unless you had an Apple tech look it over.
Good luck,
Clinton

IMac (late 2013) periodically shuts down after updating to Yosemite

I have a 27 inch iMac (late 2013, have had it 6 mos.) which I updated to Yosemite and after the update, it has just shutdown 5 or 6 times, (panic reports say 5 times). The system also seems sluggish at times... It has worked like a charm until the upgrade. I'm trying to decide whether to reinstall Yosemite -which went smoothly- or to try to go back to Mavericks. I have the System Diagnostic Reports as well as the system diagnostic test, I just don't know how to interpret the results. Does anyone have the expertise to explain what is happening? (I'm not a novice, but haven't played with unix for 18 years!)
Thanks in advance,
Mark

I have a similar problem on my iMac 27-inch Mid 2011. No problems before upgrade yesterday to Yosemite. System settings show positive connection for wifi and ethernet. But web & mail access doesn't work for ethernet. Wifi access works only if I change service order with wifi listed before ethernet.
Apple phone support blamed it on my internet provider or router. However, our 2nd iMac (identical model) has web & mail access with ethernet. The other iMac is still running Mavericks. So the problem is clearly Yosemite.
I have put in a request for Apple support to call me tomorrow, & I'll see if they try the blame game again.

IMac (Late 2013) screen display won't turn on [RESOLVED].
