IMac G4 Dislpay is Black

My iMac was in sleep mode, I pressed the space bar and the display remined black - no faint images at all. Powered down the computer and still no display. I am new to Macs and have had this used computer for only 3 weeks. What could be wrong?

Ouch!
Have a look in here Jim...
I took my Mac apart
If you are confident in your abilities, have a steady hand and read all the instructions - It can be done at home. The thermal paste part is VITAL!
Good luck if you decide to attempt it.
Post back if you need more.

  • When I turn on my iMac, it shows a black screen and says 'No bootable device - enter boot cd and press any key'.  Not sure how to fix this.

    When I turn on my iMac, it shows a black screen and says 'No bootable device - enter boot cd and press any key'.
    I'm not sure what to do, I did not recieve a cd with my mac to boot it up (I ordered it online).
    Also I can't find my harware serial number (I've tried many times to input what I thought it may be from my receipt).  I saw that I need this number to contact apple support, my 90 day complimentary support is still valid so I wish to contact them.
    I don't know much about apple products as this is my first apple computer so any information is helpful.

    Hold down the Alt/Option-key at startup of your iMac to get the Boot Selection screen.
    From that choose to boot into OSX.
    Once in OSX go to System Preferences then Startup Volume and reset your OSX to be the default.
    The new iMacs have OSX 10.7 Lion preinstalled and don't come with any CD/DVD anymore.
    Instead OSX Lion includes a new feature called "Lion Recovery".

  • Can the monitor be fixed on an iMac if it goes black (2006 17-inch, intel core duo)?

    Can the monitor be fixed on an iMac if it goes black (2006 17-inch, intel core duo)?

    Apple consider this product vintage so they won't perform any hardware service on it. You may have to look towards 3rd parties.

  • My iMac monitor just goes black

    I have a 2009 27inch iMac with an external Samsung monitor.
    Out of the blue, the iMAC MONITOR just goes black. Like it went to sleep or something.
    This has happened 4 times in the last 2 weeks. (luckily I can restart the computer because the external Samsung still works.
    I restart the computer and the monitor works fine again.
    Help.
    Thanks.

    Hi.
    Screen goes totally black.
    The good news is, I read around and was advised to turn off the computer and unplug it, and plug it back in and start up. That seems to have fixed it. So far, so good.
    Thanks.

  • 20"iMac Display Suddenly Goes Black

    While I am using my iMac, occasionally suddenly goes black. If I hit a key (usually the space bar), it comes back as if I had put it to sleep.
    What is happening? What should be done? What can I do?
    Thanks for your help and information.

    "Answered on another forum"
    What a way to be helpful! I went through your posts and searched "display" and I did not find this mysterious answer you talk about.
    I'm having the same issues on my Intel Core 2 Duo 20" iMac. if ANYONE could post a solution, I'd appreciate it.
    The computer is still working correctly. It is not on sleep mode. I've press the power button and it goes to sleep, but then when I wake it up it repeats the black screen a couple of times until it finally settles on letting me work.
    What is the point of user support forum if there are no moderators around to help people out? :/

    Not running Leopard (Panther), but I have a similar problem on my 24" iMac. Computer was working fine last night (I shut it down) and when I went to boot up this morning the computer is stuck on a black screen.
    The boot up sound is initiated but nothing after that. The power light stays at full brightness, if I touch the power button the light blinks and then after a while it goes out. A full reset does nothing. I've tried reseting my PRAM, which works because I hear the start up sound twice, but no change to the black screen.
    I don't have access to another Mac, would inserting the Startup Disc I received with the computer do anything?

    It's possible you've got a 'hot corner' set up. If you have and move the mouse to a certain corner of the screen it'll do as you describe. Have a look in System Preferences>Mission Control, bottom left of the window click on the 'Hot Corners' button and see if there is anything in there.

  • IMac keep shutting down black screen then have to hold power button down then turn it on again i did this 4 times in all of a period of 5 minutes what to do ??

    Hmm. The problem still may be the RAM - Apple buys the RAM it puts in its machines from third-party vendors (usually Hynix) so it could be a RAM problem.
    There are a couple of things that you can do yourself before taking your machine into an Apple Store or an AASP... download and run an application named Rember that will run a RAM test for you - let it run for a couple of hours or even overnight. If it turns out that your RAM is faulty, Rember will let you know. If it is faulty, then you have a couple of options - replace the RAM yourself or (particularly if you're under warranty still) take the machine to an Apple Store or AASP and have them replace the RAM.
    If Rember finds no fault with the RAM, then you'll need to take it into an Apple Store/AASP and get a free diagnosis on the machine. Three beeps do usually indicate faulty RAM, but if it tests good with Rember you likely have another problem - it could be something as simple as the RAM, somehow, not seated correctly or signs of another hardware problem.
    Run Rember first... call back with results.
    Good luck,
    Clinton

  • When I boot up my iMac I get a black screen with white text?

    Hey guys wondering if anyone can help me. I installed mountain lion on my iMac the other day (2.8ghz Intel Core 2 Duo, 24inch) and now when I turn it on I get this screen come up? Any one no of a way to fix it? It comes up black all this white text appears and at the end it says..
    "If you wish to boot the system:
    exit
    :/ root #
    You type exit and some more stuff comes up then the mac boots up, normal apple loading screen and your in?? I tried reinstalling mountain lion again and I had no luck. Still doing it? Its strange cause ML is running fine on my macbook air. If anyone has any suggestions I would be so grateful. Tell me this isnt the end of her?
    Its not something silly like the keyboard and mouse aren't connecting? I leave them on all the time.
    Heres a snap of the screen
    Thanks everyone

    I did reset the PRAM, but don't think that worked.  I did find this on a blog on the web.  It worked for me
    When I first read this post I did not realize that the Mac boots properly if you type "exit". It seems like perhaps your mac thinks you want to boot in "verbose" mode. Try this before doing a reinstall.
    http://www.ernieflores.net/osx-page-3/always-boot-mac-os-x-in-verbose-mode/
    I got this info from here
    http://www.mac-forums.com/forums/os-x-operating-system/280859-black-screen-white -text-startup.html
    note: after it starts with the white text and black screen just type exit then hit return key and the computer will startup.  open the terminal after that and follow the ernie flores blog tip.

    Difficut to say why it won't work, but my guess is your vintage iMac (about 2007) was never designed to output via HDMI. Your adapter appears correct (thanks for the Amazon link) so if you want to persist, you can contact Amazon and request and exchange to check it. But I suspect you will need to use VGA or if your TV has it DVI which would mean using a mini-DVI to DVI adapter.
    One last thought is you could invest in an Apple TV and then do it wirlessly. That would work too but requires and AppleTV to accomplish it, of course you can use the AppleTV for streaming other data too including video, photos, music etc....

  • IMac - I get a black, grey, light blue or white screen sometimes

    This has never happened to me before.
    I wasn't doing anything unusual (browsing the web) when suddenly my screen turned all black. I tried to do all possible things, like putting the computer to sleep, hit random keys, or wait a while, but finally I had to restart.
    I'm not sure why this happened and was hoping it would happen again.
    I started a game and then, suddenly, the same thing happened, but with a grey screen. As you can see, this grey screen also has vertical lines:
    http://imageshack.us/a/img267/2347/img7244m.jpg
    After restarting the computer, I launched the game again. A minute after starting it, the image of the game started to go crazy, until the screen turned all light blue, with the vertical lines again:
    http://imageshack.us/a/img703/7276/img7247t.jpg
    A few seconds later it turned white:
    http://imageshack.us/a/img15/9069/img7248mp.jpg
    Does anyone know what the problem is with my Mac? Why does this happen? I thought it may be related to the game, but the first time when it went black, I was browing the web. I hope it isn't some kind of Virus. I know they're rare on Mac, but you never know.
    I'm mentioning this because yesterday or so I downloaded an app, which is the Sendspace Wizard. Basically it's a tool to upload files to Sendspace.com. It's by far the most honest file sharing service I had used, and I've been using it for 5 years now. But you never know... I had to download this app because I have videos of a concert of a friend, it's 700 MB and this app continues broken downloads. One of the files is at 99% but it doesn't list it as finished, it's stuck there. It's very strange, I thought I should mention it as it may be related. Usually I don't like all those uploading serives etc.
    Another thing I was thinking of: the Mac was pretty hot. Usually it only becomes hot when I play the game that I have. But this time I wasn't. I heard that when it's too hot, it shuts down itself. So I thought it already did while I was browing (for whatever reason, maybe because the Sendspace tool was uploading all day long already and thus the computer was tired?) and then as I launched the game it turned it off as well because it became even hotter.
    Here the specs: iMac 27" Intel Quad Core i5 3.1 Ghz 32 GB RAM, OSX 10.8.2
    All help is appreciated !!! Hope it's nothing serious

    Anyone know? :(

  • Imac starts with a black screen and flashing white light on console

    I have a 24" imac, it is white and it is from the first year they used the intel chip. When I power it up I get a black blank screen and then the white light on the lower right side of the console flashes on and off. I hear the disk drive spin (I put the 10.4 install disk in ) and it does nothing. How do I get the disk out. I even tried holding down the mouse button at start up and that doesn't work.
    I tried to remedy this myself by resetting pram. I have taken out memory and put it back in. I have been able to get it running twice before by taking out memory and putting it back in but it only worked for a little while and then I turned it off and went to turn it back on and same problem again. Is this a logic board problem or something else. I think I read if it was the logic board the disk drive wouldn't work but I hear it spinning.
    Can anyone help me?

    Hi MacGruff69
    That has all the classic signs of unseated, improperly seated or bad RAM.
    Laying the iMac face down on a soft towel and reseat the module(s) by pressing real hard on each one with both thumbs, then closing the ejector clips and replacing the cover.
    http://support.apple.com/kb/HT1432
    Them if the iMac still has the same symptoms, try one module at a time or replace the module(s) with new one(s).
