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,
Johan

Hi 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 !

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.

Try smc and pram reset.
See if you can boot in safe mode.
See if you can boot from your lion recovery partition to use Disk Utility to repair/verify your drive (not repair permissions).

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.
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

Try starting your iMac with the original DVD that came with the computer. Then run Apple Hardware Test. If you are not able to see the screen you will need to take your iMac in for repair.

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 advance

It 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.

Our brand new quad core imac will not start up. We hear a drive and fan noise but the screen remains black. Any suggestions?

The computer shut down on its own while we were gone and will not start up again. When we press the power button we hear drive and fan noises but no chime and the screen remains black. Any suggestions?

A pretty common thing for computers that have been shipped is a RAM chip becoming dislodged just enough to cause what you are describing. Try re-seating your RAM chips. Basically just pull them out and push them back in. Take a look at this article if you need some direction on this: http://support.apple.com/kb/HT1423

IMac G4 screen remains dark

my 17' G4 iMac USB 2.0 (10.4.11) screen froze and the following messages appeared:
"System failure: cpu 0 00000008 unaligned stack"
as well as lots of the following lines:
"Unresolved kernel trap (cpu 0) 0x600 Alignment DAR" etc
Had to shut it down by using power switch. Pulled out all cables except for mouse + keyboard.
I can start it - but there is no start-up chime and screen remains black.
Tried safe boot, no response. Tried to open drive door during start up for putting in hardware test disc (mouse held down), door won't open.
Tried PRAM, no response. Tried PMU reset, no change.
Removed extra RAM I had fitted years ago and tried to start it. After I did that the iMac responds
with a 4 x beep morse code signal after turning it back on, but screen remains dark.
Also tried to start in target mode, but other 27' iMac does not "see" G4 iMac.
Anyone has any thoughts ? Don't want to get rid of this machine, I love the design.
Thanks
Walter

There is some likelihood of a hardware failure, to include
perhaps, the logic board; some kernel panic issues on an
iMac G4 could point to such an event.
Not certain if checking out such a machine at that stage is
possible with the original Apple Hardware Test, since that
relies on viewing evidence of the results in said computer.
• What do the beeps mean on startup?
http://www.welovemacs.com/whdoallthbme.html
{After Oct 1999 the four-beeps signal appears to mean a
different symptom, according to the above page...} *4 beeps =*
*no good boot images in the boot ROM (and/or bad sys config block)*

While it may not be a major melt-down, you could be in for
a project at some point in the future if you start looking into
finding other similar iMac G4s (they are getting scarce) to
use either for parts or as spares should their needs go there.
I have two running iMac G4 1.25GHz 17" & one in-op for parts.
A skilled and willing computer shop tech could probably
test the computer further, but some shops would rather
you buy something newer from their retail store. In some
cases, you may be able to get a working iMac G4 17" 1.25
for a few hundred dollars; if lucky, one in fine shape.
Perhaps one of the techie folks who frequent these forums will
see your post & offer their insights, based on experience.
Good luck & happy computing!

IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black

IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black!!

It's happened to me before as well. Try holding both lock(top right) and home buttons simultaneously until u see a slight flash of wight then just reboot it normally. If that doesn't work try restoring your device from itunes

HT201412 My ipad screen remains black and show a persistent apple logo.

My ipad screen remains black and show a persistent apple logo. Sometimes it turn on and off automatically every 5minutes. I have already restored iOS software for 3 or 4 times. I have also seen with the apple genius supporter. The problem still remain the same. Does anybody have any suggestion beyond that? I dont know how many people are experiencing the same problems. Why dont apple solve this issue seriously? My rating to apple would become dramatically decreased to zero. I have decided not to buy apple product anymore.

We are not Apple here .. you should bring your concerns to their attention.

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

My iphone 4 fell in the toilet 4 days ago and it's been drying in rice since. now when i plug it in, the screen remains black but it will vibrate. is this a good sign or is all hope lost for getting it to work again?

My iphone 4 fell in the toilet 4 days ago and has been drying in rice ever since. I tried plugging it in today and the screen remained black but it did vibrate when i switched it to vibrate. Is that a good sign? Or should I just give up hope already?

well good sign or good sign maybe a strong word
it mean that not all of the device have been damaged by the fluid
but it does not really mean that the screen will ever work again
when drying in rice make sure you don't
1 conceal it so the vapor can't escape or it will not dry enough
2 make sure to leave in on a heating source like a heated floor or radiator to speed up the proccess of the vaporising

My iphone died and when I plugged it back in to charge it when it powered on the screen remained black. I can hear when I receive a text and a hear siri. I have tried holding down the sleep and home button

My iphone died & I plugged it back in to charge when it powered on the screen remained black. I can hear when I receive a text and siri. I have tried holding down the sleep and home button and restoring in itunes neither worked. The screen on the phone is cracked but has been working fine until now. Please help!!!

Here's how to perform the restore:
HT1414
If you can actually get to restore, maybe (I estimate a 0.01% chance) you'll be able to do a backup before the restore. Actually, from the symptoms you describe, I suspect a restore won't work either and you'll need to do a recovery.
Just in case, if you need to recover (restore fails), here's how. Note you may have to try to get into recovery mode more than once.
