my iMac won't boot up. I hear the chime and the Apple symbol appears but there is no whirling indicator that appears and after a while the computer screen goes black and the whole cycle starts again. There have been occasions when it has actually started and I have the dashboard appear but then the screen freezes
Since you have Lion v10.7.4 installed, use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

It's been going on recently and even though I've tried to do an Software Update and click "sleep" before closing the lid, nothing seems to work...
Has anyone else had this problem and would have recommendations on how to fix it?
Thank you!I think the behaviour of closing the lid has changed between "before Lion" and "since Lion" - which OS version do you have? There is a free utility called InsomniaX that help control this behaviour - see http://semaja2.net/archives/206 for more info.
Good luck and let us know how it turns out.

just bought a new iphone4 and was loading os6 and now it won't turn on. the apple glows like it is starting up, then the screen goes black and then repeats the same process over and over. i have tried to reboot multiple times now
I am assuming the phone was working prior to you installing IOS 6? Did you use itunes to install IOS 6 or just run from the phone?
When I tried to do the Over The Air update to IOS6 on my iPhone 4, it errored out and I had to connect it to iTunes and select "Restore" from the summary screen after iTunes finds the phone is connected. If this works for you, it will go through a couple of reboots that take a few minutes to complete. It should then give you the option to start with a fresh new phone or to use one of your previous backups to load your contacts and other information, provided you have backed up the phone previously.
I hope this helps you my friend! -
When i try to boot itunes, screen goes black and a message pops up and says not compatible with the visual elements. how do i fix this? itunes wont even open at this point. please help. thanks
Let's first try the following document, only be sure that none of the boxes in the compatibility mode tab are checked (not just the compatibility mode box itself):

Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad or graphic card issue? Trying to decide if computer is worth repairing as it was made in 2007.
It does sound like you might have a faulty video connection. See if you can make a Genius Bar appointment at your local Apple Store.

New (3mo) macbook air screen goes black and sometimes won't come back on after I unplug it from the power cord. Any ideas why it is doing this? Sometimes I have to hold power button for 10 seconds for it to shut off then back on. Sometimes holding the power button for a second is enough for it to come back on.
I took it to the Genius Bar, and they identified it as a hardware issue. Just got it back today. Parts replaced were:
620-5629 Display Module — Symptom: Distored/blurred/focus video issue
605-3284 Top Case with Keyboard — Symptom: specific key(s) do not work
So far so good. I'd suggest taking it in and not trying to work around it — it's a rare hardware issue (given the number of threads about it) and should be replaced. -
PlayBook lags and then the screen goes black and does not respond
Hello guys,
As the Subject line summarizes, my tablet was working like charm since the date of purchase, back then in April last year. However, on these days it has been performing weird. It has always been fast and smooth, but since last week it has been lagging and not no responsive to the touch.
To tell you gusy fast and clear, it boots up as normal, fast and smooth, apps open and close as usual. Then it starts to lag, and freezes for one second, responds and freezes again but this time will not respond again and finally the screen goes black and stucks there until I make a hard reset and it reboots normally, until it does it again, and again.
Relevant information:
16GB model, 1.5GB free storage available, sideloaded a few android apps today, recorded a few videos
the device manager software on the pc makes no difference, as the PB will anyway freeze and go all black even if it's backing up or something.
HELP?Make sure any important data is backed up preferably by drag and drop to a pc.
When it is working properly, try gently squeezing the playbook between finger and tbumb around the black bezel border. Especially either side of the lower sockets. If it goes black it's probably a bad battery or screen contact.
1.5 GB is not much spare storage, by the way. I would never fill more than 75%. -
While browsing the internet with my iPhone 4S the screen goes black and it looks like it's turning off, but it pops up to the unlock keypad screen. It has plenty battery and I was wondering if it is an issue of using too much of the iPhones RAM or not. I have no other apps open besides Messages. I am getting kind of worried as it started around two weeks ago and it has gotten increasingly frequent.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.

I haven't been able to find any answers that solve my problem. My Ipad will not leave the Apple logo. I hold both buttons and the screen goes black and then the Apple logo immediately pops back up. I can't get the red slider screen at all. No matter how many times I hold down both buttons the screen goes black and then the Apple logo pops right back on.
Before you do anything else, try charging via a wall outlet for a while, since its off. Then try turning it back on.
When you put the device into recovery mode it allows you to restore the device when no other options work. You do risk losing everything currently strored on the ipad itself. Hopefully you've performed regular backups either via itunes, icloud or both. Evern if you have synced content to either of those, you may not lose everything. All previous purchases have been saved in the itunes and app stores, so you can dowload them again.
while the ipad is off, press and hold the home button and plug the usb cord into the ipad. You should see a message pop up on the itunes window on your compoter screen that state it has discoverd an ipad in recovery mode.
You should now be able to restore -
I have a iPad, 32g, and for no apparent reason, the screen goes black and whatever app I am using is closed on me. It seems to be happening more and more frequently, especially when loading apps, or trying to watch a YouTube video. I try to open safari or youtube again and it will often crash several times before it may or may not decide to load for me. It is extremely annoying and getting to the point where I can not use it
Standard troubleshooting steps in order are as follows:
Power the iPad off and on.
An iPad reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
Restore your iPad with iTunes from your iPad's backup.
Restore your iPad with iTunes as a new iPad or not from your iPad's backup.
If no change after the last step, your iPad has a hardware problem. -
When I open my internet and got to say the Macy's website and try to bring up all pages in the handbags dept, the screen goes black and it returns to the screen that has all my icons on it. Why?
Safari is crashing.
Try a reset:
Hold the home and power buttons at the same time until the Apple boot logo appears. No data will be lost. -
When on a phone call when I need to enter numbers on the keypad, the screen goes black and the device doesn't register the numbers. Sometimes it works, but most times not...very frustrating. Any recommendations?
Is there a case or screen protector that is possibly interfering with the proximity sensor (detects if the phone is near your face, allows the keypad/screen to be visible when the phone is away from your face)

I can not get my iPad to mirror on Apple TV. When I toggle the tv screen goes black and the iPad freezes. Have updated the iOS to latest settings and also updated the settings on the Apple TV
Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device. -
Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.
I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly... -
My iphone's screen goes black and it behaves like that it is switched off.No switches work and the power button also does not respond.The ringtone do not also respond.The only way to switch on the phone is to press home button and power button together.
Pressing the Home button and the sleep/wake or on/off button together until you see the Apple logo and then release is called a reset.
If no change after a reset, the next step is restoring your iPhone.
