2009 Core 2 Duo iMac Display not turning on, but everything else is.

The iMac turns on, but NOTHING is on the screen. The machine boots fine, and can even connect to an external display. Help?

That is a tough problem since you don't seem to be able to boot from anything, hard drive, install disks, external. Sounds a lot like a failure on the logic board. And goes to the AirPort card twice before failing. Are you able to take the iMac to an Apple Retail Store genius bar or an Apple authorized repair service? This would be a good problem for their diagnostics.

  • IMac Display not turning on after sleeping for a while

    Hey Guys,
    Minor issue I've had with my iMac for the last few days, when I wake up I tend to nudge the mouse to turn on the display before taking a shower so that everything is ready for when I get back. However the screen isnt coming on and I'm having to press the power button to sleep the iMac then wake it up again by pressing the power button 5 seconds later, after that, all is good.
    Any ideas? This has been since upgrading to 10.6.4
    Thanks

    Yeah I might think it's overheating too, but the harddrive always makes this strange noise before the crash happens, so it could be related to the hdd? Or in the worst case, the motherboard.
    Any tips on how to check for overheating? I have tried to run temperature monitor software, but the only sensor it detects is the hdd, and it looks fine.
    I haven't opened my iMac fully ever, just the user serviceable parts. I installed an Airport card about 1 month before this started happening, could this be related?
    Pierre, what did you do when your iMac started overheating? How did you fix it? Mine just full crashes and the screen goes weird. Thanks for your answer.

  • The screen Turned white but  Everything else is working!??

    hi
    i had the macbook Core 2 Duo for About 8 months and it was working great.
    yesterday i left a file download in firefox for 5 hours then went back to check on it , it was working FINE, Then i got Back after 2 minutes and the screen is suddenly white and not showing anything!!
    i shut down the laptop and restarted , there was a chime and just white screen...
    i connected the laptop to an external monitor AND EVERYTHING IS WORKING on the external screen but the laptop screen is white!!!
    i tried resetting the PRAM and i tried resetting the SMC twice but nothing Changed>>
    i can't use the apple hardware testing because the external monitor does not work till the system loads (and it does always)and i will be working blind..
    so , is this a sudden hardware thing in the screen or what ?
    i'm on a 3 year waranty but i don't have an apple store in my country !! can i send the laptop to them via mail?
    Where can i ask them directly via mail?
    i previously backed up the laptop via time machine and i can fully use it on the external display , so would a restore of system folders HELP at least rule out system errors???
    i searched for similar problems but none seems to match mine because other people always had a system error , and i don't seem to have one..
    Please Guys any answer might help me , i have tons of work...

    If you are not showing reception bars, then I don't know how the data is working? Have you tried doing a reset? Hold the sleep/wake and home buttons together until you see the Apple logo and then release. After the phone restarts, check to see if it works. If that doesn't help, then try removing the SIM card, then reinserting it. If that doesn't help, then contact your carrier for assistance in calling.

  • The backlight on my ipod touch 3rd generation will not come on, but everything works perfectly. I even used the advice given on the tech support page, and it still will not come on. HELP ME PLEASE.

    The backlight on my ipod touch 3rd generation will not come on, but everything else is working fine I even took the tech support advice by plugging it in and resetting it, but that didn't fix the issue either. I need help.

    If not this:
    iOS: Wi-Fi or Bluetooth settings grayed out or dim
    One user reported that placing the iPod in the freezer fixed the problem.
    Also heating sometimes works. See:
    Why can't I select my wifi settings?
    A trick that works frequently with iPhones:
    Settings > AirPlane Mode ON, Do Not Disturb ON
    Power down and wait 5-10 minutes
    Power up
    Settings > AirPlane Mode OFF, Do Not Disturb OFF
    If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
    Apple Retail Store - Genius Bar
    Then:
    Does the iOS device connect to other networks? See other networks? If yes that tends to indicate a problem with your network.
    Does the iOS device see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on your router
    .- Reset network settings: Settings>General>Reset>Reset Network Settings

    - Wi-Fi: Unable to connect to an 802.11n Wi-Fi network      
    - iOS: Recommended settings for Wi-Fi routers and access points
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • My 2011 intel dual core duo iMac apparently has "Airport" ans apparently it is "on" although the icon (upper right) is gray. I'm not sure what "airport" is

    My 2011 intel dual core duo iMac apparently has "Airport" ans apparently it is "on" although the icon (upper right) is gray. When I click on the <gray> airport icon it says it's "on" and the option is to turn it off.
    I'm not sure what "airport" is, and I have no idea what a router is supposed to accomplish. I got a "smartphone" (not an iPhone, an android) and at a "Smartphone class" at the senior center I was told I need a router.

    OK, so, in installing a router could I attach the router to my Verizon DSL modem and have the iMac get it's internet from the router by wi-fi?
    This way I could place the router 1/2 way between the only two places in my home where wifi devices (wife's tablet, my iMac) are.
    Yes, exactly.
    For the router I suggest you consider one of the three Apple AirPort Base Stations, not only because it will be easier to get help with using them on this website, but they are generally regarded as the most reliable wireless routers. Technical support directly from Apple is free for the first 90 days.
    Slightly cheaper alternatives exist. I have tried other manufacturer's wireless routers, and I don't recommend them.

  • Intel iMac will not turn on

    So here's the deal: The other day I noticed things were acting buggy on my Intel Core Duo iMac (the white, matte-screen one). Performing simple tasks like opening a folder or window caused the spinning beach ball for at least 30 seconds or more. Email wouldn't open without the spinning beach ball going on for at least a minute or two. Also, there is an intermittent click coming from inside the computer. Maybe every minute or two--click.
    So I restart. Things seem fine. But then the hang ups start again. So I boot from my Snow Leopard disks and run Disk Utility. Verifying permissions takes a very long time but I finally get to repair permissions. Then I try to verify the disk and repair but I get an error message in red saying something like "this disk cannot be repaired". So I shut down and try to start up from Disk Warrior. Once the Disk Warrior window comes up the iMac shuts down. I try this a couple of times.
    I check the forum and try the suggestions of holding down P and R (or something like that), unplugging and pressing the "on" button before plugging it back in. Nothing works. I get to the gray screen and it shuts itself off.
    After that I try to start it up as usual and when the gray screen comes up I have an apple logo and beneath that a status bar and as soon as the status bar is complete the computer shuts off. I try this a couple of times. Finally it won't even start up at all. It's as if it's not even plugged in. No chime, no internal noise, no "on" indicator light, nothing.
    If my hard drive has failed, does this mean my computer will not even turn on? If my hard drive has failed and I could turn my computer on, what would I typically see? A blank screen? A question mark?
    Any ideas or suggestions?

    Update: So I took my iMac to the Apple store and they ordered a power supply and a new hard drive. The plan was to install the power supply and see if that's all it needed. If the hard drive was dead they would then install the drive. The wanted about $95 for the power supply, which isn't bad, and $248 for a 320 GB hard drive. Installation was going to be around $85. After I placed the order I went home and checked prices online and found I could get a 1TB hard drive for less than $120! And a 500 GB for around $60! Why would Apple charge me $248 for a 320 GB drive? During this time I also found a local Mac repair shop that was willing to install the power supply for me and, if needed, a new hard drive that I could purchase much less than Apple's price. So the parts came in and I went to the Apple store thinking I could purchase the power supply and walk out. No dice. Apple would not sell the power supply to me. They insisted they can only sell it to me if they swap it out for the one in my iMac. I told the guy, "that's okay, I only want to buy the power supply". He sort of apologized and said they can not do that. ***? Why wouldn't they sell something to a customer willing to buy it?
    Long story short, all of my business is now going to the local Mac repair shop and not the Apple store. I'll never take anything that's not in warranty to the Apple store again. And I'm sure they couldn't care less.

  • Disk Utility hangs while initializing internal hard disk in Core Duo iMac

    I have a 20" Core Duo iMac. Recently the internal hard drive crashed ("invalid B-tree node size" or something reported when Disk Utility tries and fails to repair it). I have all my data on an external hard disk used as a Time Machine volume, so recovery is not my issue. Initially I picked the write zeroes once security option and chose to erase the internal hard disk. Realizing this would take too long, I clicked on skip, and Disk Utility appeared to hang. I quit and restarted Disk Utility, and chose the "don't erase" security option, but when I go to erase the drive it appears to hang while at the "partitioning" stage and doesn't seem to get any further. There is motion in the progress bar, but no additional progress after about an hour. Disk Utility shows the disk but no volumes underneath it (whereas immediately after the crash, it showed an unmountable volume labeled "disk0s2").
    Why would Disk Utility be taking so long and not making any progress? How can I reformat this disk if Disk Utility is not able to? Incidentally, I am running the Disk Utility that comes with OS X 10.4.8, since that is the OS X version on my portable hard drive that I booted from. I also tried using Drive Genius to initialize the hard disk, but it also appeared to hang with no progress.

    It is possible the drive has failed, but to be sure start by turning off the computer. Wait five minutes. Then do this:
    Extended Hard Drive Preparation
    1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Set the number of partitions from the drop down menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Be sure to boot from the OS X installer DVD, not a backup clone.

  • Airport Extreme 802.11n upgrade options for early Intel Core Duo iMac

    I have an iMac from mid 2006. I recently purchased a Timecapsule - partly for the wireless back ups, and partly to upgrade my wireless network to 802.11n. There is a software upgrade from Apple that upgrades older 802.11 a/b/g Airport cards in the iMac to 'n' standard. Here is the link:
    http://store.apple.com/uk/product/D4141ZM/A?fnode=MTY1NDA0Mg&mco=MjIzMDkzNA
    The page states that the upgrade is compatible "If you have a Mac with an Intel Core 2 Duo processor (except the 17-inch, 1.83GHz iMac)". What it doesn't tell you is that if you have an early version of the iMac (pre-Sept 2006) that shipped with the Intel Core Duo Processor (note - not the Core 2 Duo) then the upgrade will not work. I have also tried to install Airport Extreme updates (2007002 and 2008004) and these report that the hardware is not compatible. Doing some searching around these forums and others, the issue with the original Core Duo iMacs not being upgradeable to 802.11n is out there - shame Apple weren't more explicit.
    I have seen that there are various USB based 802.11n adapters available. Whilst searching on this topic, I also came across a site offering various Mac upgrades, including an upgrade to the Airport card to upgrade wireless capability from 802.11g to 802.11n. It looks like a straight replacement for the internal card - link here:
    http://www.macupgrades.co.uk/store/productinfo.php?productsid=461
    The company offering this is in the UK, but the product appears to be from a Sonnet, a US company. Does anyone out there have experience of installing this product (or having it installed) and can you comment on how it performs? Is it a seamless replacement for the original Airport card?

    What it doesn't tell you is that if you have an early version of the iMac (pre-Sept 2006) that shipped with the Intel Core Duo Processor (note - not the Core 2 Duo) then the upgrade will not work.
    If it says you need to have a Core "2" Duo processor, then it seems to me they are telling you very clearly that it will not work with the earlier Core (no "2") Duo iMacs.
    The "late 2006" iMacs with Core 2 Duo (except for that one education model they mentioned) have wireless networking hardware that is 802.11n capable. When they were initially sold, Apple chose to NOT enable the "n" capability for some reason; maybe because the standard was still in flux and not enough testing had been done with the driver. Later, they enabled the "n" capability with a firmware update. But that was only possible because the wireless hardware was already capable of doing "n."
    Earlier iMacs do not have this hardware so there is no way to enable it with a firmware or software update. 802.11g is plenty fast enough for Internet access (you won't notice a difference with "n"). If you are using Time Machine over wireless, it may take a while longer to do that initial backup (you could connected it by Ethernet cable when it is doing that initial backup), but subsequent backups are incremental, so the "g" versus "n" speed difference will not be as critical. Since your iMac is Core Duo (32-bit) and the future of Mac OS X is 64-bit, especially after Snow Leopard's release, it may be best to save your money and keep your iMac intact (not opened).

  • Upgrade card for Core Duo iMac to benefit from Airport Extreme

    I just bought Airport Extreme for "n" speeds. I didn't realize it required Core 2 Duo for the fastest speeds. Does anyone know of an upgrade card I could install to my Core Duo iMac? Thanks.
    iMac Core Duo, iMac Core 2 Duo, MacBook Core 2 Duo   Mac OS X (10.4.8)  

    There is an article floating around the web of
    removing the 2 antennae extreme card from a Mac Pro
    and installing it in a MacBook to get 802.11n
    connectability, but the connection isn't reported to
    be any better or faster.
    Also, everything on the network must be 802.11n to
    get the n speeds. A mixed network is slower.
    I just took the Airport Extreme 802.11n module out of my Mac Pro and installed in my CoreDuo MacBook Pro. After applying the enabler patch off the CD, my network connection speeds report as 270mb connecting to a wide-band N-only Airport Extreme Base Station.
    Performance boost on initial file transfer speeds are significant. A 203mb test file took 6+ minutes on my G-only network. The same file, on the N-only network took 49 seconds.
    I would call that both better and faster.
    Of course for those looking to use it on the mixed B/G/N networks to surf the web aren't going to notice any difference. I think a lot of people forget that regardless of their wireless network speed, even on the fastest of home broadband connections they're not going to be getting more than 8mbs coming into the WAN side of the network if they're on fiber cable. A DSL connection might get 2mbs. The internet itself for most will be a significant bottleneck for most users.
    If you're doing a lot of transfers of large files on your internal LAN, the performance is worth the $49 part.
    What's really bizarre is that Apple chose to put 100mbs wired ethernet ports on the Airport Extreme Base Station, which means when I hook a USB drive to it, I should actually get faster transfers wirelessly than wired. How bizarre is that?

  • G5 iMac Will Not Turn On - Power Supply Diagnosis?

    My A1145 20" iSight PPC G5 iMac will not turn on - it doesn't respond to the power button. It had been shut down for a few days, I turned on the power and it booted up as normal, the desktop appeared and I was about to open the web browser when it suddenly went dead; the screen immediately turned off with no warning or noise. There is no fan or disk noise coming from it when the power lead is plugged in, just a very, very faint electronic hum from inside.
    From reading various webpages, it seems possible that the power supply could have failed. Is there a simple way that I can diagnose this before deciding whether to attempt to replace it myself or not? I understand that there should be some diagnostic LEDs which could help identify a problem - I've removed the surround from the iMac and peeled back the black EMI film below the display but I'm not sure for what or where I should be looking (they seem to be easier to find on the 17" models).
    Whilst I know a repair might not be cost-effective on such an old machine, I have 220GB of photographs, documents and music on it - none of which is backed-up - so I am very keen to get it working and backed-up as soon as possible.
    Could anyone suggest how to diagnose the problem?

    Hi there:
    My experience with Macintosh computers has not included the G5 iMac even though I almost got one to replace a failed-under-AppleCare iMac G4 17" 1.25GHz after three/four major failures and no local support.
    ...So, I think you may be able to pull the hard disk drive out of that computer and see if an external enclosure could allow you access those files IF the drive spins up at all. Sometimes odd things happen, and the G5 iMac had some history of capacitor and other failures that could be a problem. I see there are a few free information guides here that may be helpful: http://www.ifixit.com/Device/iMac_G5
    If the battery on the logic board was dead, but the computer kept in running condition by leaving it plugged in, once the computer was left unplugged for a time then the device may fail to start. There is a way to reset the power management chip (different names for same idea as technology moved forward) and that could help in the process of troubleshooting most power related issues in the PPC Macs of later G3/G4/G5 design.
    There are troubleshooting items of interest in here http://www.apple.com/support/imac/g5/ ie: what to do when your computer won't turn on...
    Sorry to not be of direct help in this matter.
    Good luck & happy computing!

  • Clean Installation Of FCE 3.5 UPGRADE On Core Duo iMac?

    In a previous post Scott told me that when I get a new Core Duo iMac I will be able to install the UPGRADE version of FCE 3.5 straight away without needing to install the old FCE 3 first. (I will need of course to use my FCE3 serial number).
    I have just contacted the UK Apple Store and was told that I would probably need to install FCE3 first! However, when I challenged him the rep wasn't too certain!
    Does anyone definitely know whether I can just go ahead and install from the UPGRADE DVDs without needing my original FCE3 DVDs - apart from the serial number?

    It's pretty quick and easy to install Player and give it a try.  Another advantage to that approach is that there's only a single OS at the top level and backups can capture the whole mess w/out having to deal with 2 or 3 different OSs and their partitions.

  • Upgrading a Core Duo iMac

    Is there an "economical" way to upgrade a Intel Core Duo iMac to a Core 2 Duo iMac to be able to run Lion?   I think I know what the answer is: purchase a new or refurbished Core 2 Duo iMac but I just wanted to check.  I have a Core 2 Duo MacBook Pro and thought having the iCloud available for both computers would be helpful.
    Thanks for your suggestions.
    Vernon

    Hi Vernon,
    The processors on Apple's iMacs are not upgradeable, they are part of the logic board.
    Apple has some very reasonable deals on refurbs here and even new iMacs are very affordable. You can also look for good deals for used machines on CraigsList or eBay. It takes some searching to find the right deal but if you work at it you can come up with something worthwhile.
    Best of luck.
