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.

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.

My iPod touch won't turn on. I have tried plugging it in to charge, but and the screen remains black. I have tried restarting/resetting it to no avail. I would really appreciate your help. Thank you.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

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

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

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

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:

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.

We just moved from the United States to Costa Rica. The first two days my mac worked great. Then all of a sudden I was trying to use a game application and the screen went black and there is a white cursor which I can move around, but I can't escape it

We just moved from the United States to Costa Rica. The first two days my mac worked great. Then all of a sudden I was trying to use a game application and the screen went black and there is a white cursor which I can move around, but I can't escape it. When I restart it seems okay and I see my main screen, but only for a second and then it goes black again.
This computer was brand new in June. Is it the humidity??? What can I do. Please help!!!!

For instance, DigiDNA's DiskAid will let you extract your messages from the phone in human-readable format. Like .pdf.

IPhoto 11 9.3 I click on a thumbnail and the screen is black or has a triangle with exclamation mark inside of it

iPhoto 11 9.13 I click on a thumbnail and the screen is black or has a triangle with an exclamation point

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

My ipod touch is flashing white on and off, I hold the buttons down, and the screen goes black- but the apple logo does not come on. What do I do?

So I have had this problem before, and know that you hold down the top Power button and the Home button, at the same time, for roughly 10 seconds, or until the apple logo comes on.
The problem is, when I press the buttons and the screen goes black, like it's supposed to before the logo pops up, the apple logo isn't appearing.
I was wondering if that's because my I pod touch was drained when I plugged it in to charge, and I tried to turn it on when it was still charging?
What can I do?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

Decided to update iphone 4 to ios 5.1 and mid update it froze and the screen is black. Phone does not respond to any combinations of home and power buttons, when plugged into computer it does not see it is plugged in, any ideas?

Decided to update iphone 4 to ios 5.1 and mid update it froze and the screen is black. Phone does not respond to any combinations of home and power buttons, when plugged into computer it does not see it is plugged in so I cannot restore or anything. Looks like the screen is on it's just unresponsive and black obviously. Has anyone had this problem? I was updating via wifi right in front of my router and my computer.

Spoke to a "senior advisor" in the Apple TV department. Her suggestions: change channel in router to minimize/eliminate wifi interference from other users; move router away from any metal - i.e., DVD player, phone modem, etc.; keep router away from wireless 2.4 gH phones, which are "notorious" for crashing wifi routers. So she confirms that the problem is one of connection to router suddenly dropping out.
My own feeling is that none of these fixes will do the trick, because it seems pretty clear that there is a hardware component here - the timing of the drops seems like an overheating issue. It takes 35-40 minutes for the box to warm up enough for the first drop; then each consecutive drop happens quicker than the one before, as it heats up more. Each time it drops, its tiny brain gets a little more scrambled; last night it finally wouldn't start up again at all.
My suggestion is that everyone who is experiencing this problem, please call Apple tech support and ask to speak to a senior advisor in the Apple TV department. Make them aware of this problem!
