Why does my iMAC (mid2011) screen suddenly go black?
Even though the machine is not being run hard or taxed, nor is the temp particularly high, the screen will suddenly go black.
If I then send it 'to sleep' and press a key display acts normally until next time - there doesn't seem to be any pattern to this, nor does it happen under specific applications?
Been happening on and off for a week now and unable to find any solution as
Help/advice please-rather worrying!!
Part of the many problems with the LG panel in it. The solution is to have the display replaced which is quite expensive. To find out what the options are take it in for a diagnostic test.

Why does my Mac's screen suddenly go black?
Whenever I'm using my Macbook Pro, the screen will sometimes suddenly go black. It does it even if I'm doing different things. It' not hard to get it back on, I just have to click the mouse or press the space key a couple of times, but then the mouse doesn't work for a couple seconds. It's not that I'm not using it (I know that if you don't move the mouse for too long, the screen goes black), there's definitely something wrong with the computer. What should I do? Thanks!!
You can also check your Energy Saver "Display Sleep" options.
Depending on your model Macbook Pro, this may apply - MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video. Affected computers were manufactured between April 2010 and February 2011.
MacBook Pro: Distorted video or no video issues . The affected computers were manufactured between approximately May 2007 and September 2008. -
Why does my ipad 2 screen keep randomly blacking out?
Ipad 2 just screen randomly blacks out. As I type this ? it has done it twice!
First thing to try is a reboot of your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
If that doesn't correct the problem make an appointment at an Apple store to have the iPad looked at. -
Why does my Palm Vx screen fade to black?
The screen comes on for a split second before fading out as if the contrast were set all the way up.
Any suggestions, theories, comments or urban legend causes and solutions are appreciated.
Thanks
Post relates to: Palm Vxhi tom. someone posted a solution for my problem. i think it's the same for your problem.
on the top of your palm there are two buttons. click the one on the left. it will bring up the contrast control at the bottom of your screen. slide the control thingy to the left and the screen will become bright again!
let me know if it doesn't work.

My iMac is less than one year old. Without warning, the screen suddenly goes black. It used to happen ocasionally, but now it happens all the time. Numerous people have posted about this issue. Why hasn't Apple solved the issue. For what I paid my computer, I expected more from the product than I have gotten. I was a PC person for years and most of my associates told me that I needed to get a mac...I am starting to regret having taken their advice.
Sorry you're having this problem.
A few years ago we had a similar issue on one of our machines, it was an early MacBook. Ended up being a cracked circuit connection on the motherboard. Changes in temperature caused the crack to expand and contract resulting in a shut-down followed by an automatic reboot. Sometimes over-and-over. I understood from AppleCare at the time that those symptoms could have also been any number of things including a intermittent issue with a powersupply.
If you take it back to the Apple Store at some point, I would ask them to have it run some CPU intensive tasks that closely resemble what you are doing when the screen goes black. It took us several try's to find the problem. Calling AppleCare each time to discuss it and troubleshoot before making the trips to the Apple Store really moved things along. In fact, it wasn't until the Apple Store had cracked the case from the inside that things kicked into a higher gear and AppleCare phone support sent out a pre-paid FedX package to send it to a refurbishing facility. Never a problem since and I know the people who have the machine today.
PS Can identify with the trip to the Apple Store, our closest one is in Knoxville, 2hrs from us. -
Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over.Hi,
When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...

Why does my imac get a black screen when switching on
why does my imac get a black screen when turning on, and logging in is very slow.
I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these procedures don't solve the problems.
Hope this helps -
Why does my iMac display go off when I am starting up or waking up my machine from sleep..
Why does my iMac display go off when I am starting up or waking up my machine from sleep..?
When my iMac goes to sleep I then later try to click the magic track pad or keyboard and it will usually then show the initial password entry login screen and then go off. The machine is still on but the display is black and will sometimes flash up the screen again if I press the magic track pad or keyboard but will then black out again..Well, there are many different reasons why it does this. It might shut off due to power voltage problems, system overheats, or there is a System Problem. The reason it might be hard to boot up is because your power button might not work properly or your system hard drive is damaged.

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?
The screen isn't broken because it works after i turn the device off and back on, but after it goes black once, it's only white again.
But it takes the touches although it's only white, because I can answer my phone when I slide my finger on the bottom of the screen, eventhough there in not the button to see.
This is so weird. I have already done everything I can think of that might help. But I cannot think of anything that might be causing it, because nothing has happened to the device.Let me know if I should start a new discussion instead of opening a new topic here.
My wife's iPhone is the same vintage as mine 3Gs, but has never had the battery problem. Its affliction instead is that it cannot detect WiFi networks unless it is quite close to the source. Often, when my iPhone not only detects but shows a maximum cells connection with a network, hers cannot detect the network at all. In contrast, her iPhone seems to detect ourcellular carrier just as well as mine does.
Is there any help for this affliction? -
Why does my iMac only have 1 GB of memory?
Put in more RAM. Visit OWC, DataMem, or Crucial.com to purchase memory for your model. You computer would have more memory had you put more in a long time ago.

Why does my iMac appear many times in my network and labelled 1,2,3, etc
why does my iMac appear many times in my network and labelled 1,2,3, etc
Ok, I solved it.
I followed this steps:
1- Turn Off Wi-Fi from the Wireless menu item
2- From the OS X Finder, hit Command+Shift+G and enter the following path:
/Library/Preferences/SystemConfiguration/
3- Within this folder locate and select the following files:
com.apple.airport.preferences.plist
com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
preferences.plist
4- Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if needed.
5- Reboot the Mac
6- Turn ON WI-Fi from the wireless network menu again -
