IMac g5 screen remains black when turning on
My iMac 2.0 gz ppc g5 froze up while net surfing. I turned off power strip and when I turned computer back on all I hear is the fan running, the power white light is on but the screen remains black. Am I in some weird sleep mode? Or worse? I' m running 10.5.8
Try rebooting in Safe mode:
To start up into Safe Mode (to "Safe Boot"), do this:
1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

Have a 3 yr old iMac the screen goes black when using it it will come back on when you move the mouse thanks for your help Dave
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.

Laptop screen remains black (off) when I turn on the computer
Hello,
Today I came home and turned on my laptop as usual except this time the screen remained black. I can hear the fan running and then the usual windows chime at start up, but nothing to view. The HP logo at the back still lights up though. Just the actual screen remains completely black like it is off. I tried connecting it to my tv via HDMI and to an external monitor but there's no signal. I also tried doing a hard reset which I read about here but that did nothing. I feel as though it's just the monitor won't turn on but everything else might be fine.Hello @brianh123,

I have read your post on how your notebook's screen remains black when your power on your computer, and I would be happy to assist you!
Since the image will not appear on either the notebook or the external monitor, I believe there is a startup issue with your computer. To enable your notebook to power on correctly, I recommend following the steps in this document on Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.
If the issue continues, I recommend contacting our technical support at 800-474-6836 for hardware replacement options. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

When using my iMac the screen turned blue and so I turned the compute off. When I turn on again power does get to the computer but there are no chimes and the screen remains black. Any advise please. David
Hello DJJOC,
Thanks for using Apple Support Communities.
To start troubleshooting this issue where your iMac's screen will not illuminate, please reset your SMC by following the information outlined below.

IMac 24 inch screen remains black
Hi,
iMac starts up in normal way but screen remains black. When I do Screen Sharing from my MacBook Pro I see there's nothing wrong with the iMac ... on my MacBook Pro the normal screen from my iMac is shown.
Please some help?
Many thanks,
JohanHi guys,
got the same problem. I've even talked to apple's 2nd level support about it.
made pictures for them and so on. Now the important questions!!!
Are you guys smokers ? I bet you are
Apple's 2nd level support told me that this is caused by smoking infront of the imac.
And their solution to this problem (at least here in germany) is to get it cleaned and tell you to stop smoking in front of it !!!!!!!!!!!!!!!!!!!!!!!!!
Because there are not enough complains about this problem from customers !!
I'm soooo **** !
Please everyone let apple know (call them) that this is a big big problem and they should redesign the iMac's (if it is a design flaw).Or give everyone that has this problem a new one, that doesn't have this problem.
Smokers unit !

MacBook Pro 2008 not turning on, no sign of power and screen remains black
I have a MacBook Pro 2008.
It was working fine until when one morning i wanted to turn it on as usual only to find out that it can not power on.
When i press the power-on button, i can hear the hard disk spinning but no display, the screen remains black like not getting power.
No beep sound when tried to boot without RAM installed.
The battery and the Charger worked fine when tested with another computer.
The RAM works fine when tested with another Computer too.
What could be wrong with my computer, i hope it is not the board that is dead.
How can i overcome this problem?Op Charles,
You can try a SMC reset:
http://support.apple.com/kb/HT3964
Follow directions for a battery that applies to your machine.
http://support.apple.com/kb/TS1365
http://support.apple.com/kb/TS1367
You can check these as well
It sounds as thogh the the GPU may be dead, you can take it in to an Apple Genius (make an appointment) they will disgnose it for free and give you your options.
Good Luck -
Screen stays black when I turn my iBook on, no response. HELP
I really hope someone can help me with this cause the laptop in question belongs to someone else and I'll be in a tough spot if I don't fix this...
So I've been borrowing this G4 iBook. I've installed some software, including some "whois" programs from the internet. I've also been downloading torrents via Transmission. Anyway, this is what happened:
I was downloading a torrent, and I had Safari open. I began to transfer a movie to the Apple-TV system I have when things started running slowly--so I went to the energy savings panel and optimized the processor for highest performance. Things kept running slowly so I began to quit programs. Finally I had only the Apple-TV transfer open but the Finder wasn't responding (rainbow wheel).
I tried to relaunch the Finder by force-quitting but no response. I then tried to restart, no response. So finally I held down the power button to shut the computer off. Now when I turn it on I hear the start up sound but the screen remains black. I think the keys are unresponsive too cause I tried pressing the power button and pressing 'return' to see if it would restart or shutdown. Nothing. I mentioned that I've been downloading some software and torrents for the off-chance that I have a virus. I have a Norton Antivirus CD if I need it. I don't know what to do though.
I'd really appreciate some help here. It would save me the embarrassment of having to take the laptop to get repaired.Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
See if this works...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.) -
TS3474 My nano will not power on when fully charged, screen remains black.
Bought early 2012, no idea what generation it is. When connected to the stereo, the screen illuminates and nano works with stereo controls. When I try to take the nano for a run, when holding the power button down the screen remains black and no amount of touching the screen will produce an image or any sound. Any ideas about troubleshooting the black screen when powering up un-connected?
Hello gatormother,

Will not turn on or screen remains dark
Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
If iPod does not turn on after ten minutes, try resetting it while it is still connected to power. Reset the iPod by holding down the Sleep/Wake button and the Home button for at least six seconds or until you see the Apple logo appear.
If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
If the screen remains dark and will not turn on, then your iPod may need service.
Have a nice day,

IMac G5 isight not booting, screen remains black & fans start
Hello,
The iMac in question is a 2.1 G5 20" screen with iSight. It has worked perfectly with no problems up until recently, now when I go to switch on the chime sounds, the screen remains black and after about a minute the fans startup.
I have attempted to reset the SMU and PRAM to no avail.
I did manage (after several attempts) to boot into Target Mode with another mac connected by Firewire. The hard drive shows up and all the files seem to be there. I scanned the drive with TectTool Pro and repaired permissions, I also used Disk Warrior to rebuild the drive. Still the problem persists.
Tried to boot from CD but so far this has been unsuccessfull.
I have read of people having similar problems but have yet to find a working solution but I'm hoping there is one out there as the iMac was working wonderfully right up until this problem!
Thanks in advanceIt sounds as if your power supply is failingand/or your logic board. I think it's time to take it in and have it looked at. But before you do that, try running the Apple Hardware Test, on your install disc.

Satellite A300 - Not turning on, screen remains black
I have a Satellite A300 laptop. I tried turning it on when I got home from work and the monitor remained blank. The lights come on the bottom (the plug, the power and the battery lights) but the screen remains black.
Can someone help me?Hi
Its difficult to say whats going wrong here but maybe its just a small issue which could be solved easily.
Try this;
Remove the battery, disconnect the AC adaptor.
Then wait some hours and plug the both parts again.
I had such issue in the past and leave the notebook disconnected during the night.
Next morning I plugged battery and A\c adaptor and the notebook worked again
Maybe this will help you too -
