IMac 2011 screen unexpectedly goes black (to sleep), won't wake

I've been having an intermittent problem. I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all. Very annoying. Verified the internal drive, repaired permissions; no problems noted there.

Exactly the same issue here - same machine and OS. got so bad now that it blacks almost as soon as it comes on. Over the past few weeks I also experienced the flickering screen that others have complained about. The black screen only occured after installing latest update (7.3) - and I only installed this after earlier problems with the update reported by many users were sorted - but the flickering happened before so may be not relevant.
What's happening when you press the power button a couple of times is probably that you have 'use power button to put computer to sleep' selected in System Prefs. Henmce, 1 push puts it to sleep and 2nd wakes it up.
I have done all the usual checks plus power down, unplugged for 20 seconds and then restarted to reset the SMC (System Managemenmt Controller) but problem has recurred - normally after sleep.
Aplle did have a large batch of faulty LG screens apparently so maybe this is the poblem. Otherwise maybe graphics card issue,
Mine's off to a service centre tomorrow whilst it's still under warranty... will update when I get it back

Lenovo z50 screen keeps going black

I've had it for around 6 months with no problems, then in the last 48 hours, the screen keeps going black when I'm using it. It happens every 20-30 minutes. If I close the laptop lid and open it again, it works fine until the problem comes up again. I've tried downloading updates and placing a fan by it, but it keeps happening. Any ideas?

I dropped my ipod in coke. The screen keeps going black. Is there anything i can do?

Your iPod is toast. No amount of dry rice is gonna help.
"Coke" and other carbonated drinks are acidic (carbonic acid), not to mention loaded with sugars and other nastiness.
The acid will "eat" metals, like the lead and tin in solder, most liquids will wreak havoc with the LCD display, and since "Coke" and its cousins are acidic, they are also good electrolytes and will conduct electricity.
You can try filing a claim against your home owner's insurace, but barring that, you're out of luck.

SCREEN OCCASIONALLY GOES BLACK

Hi: I have a Mini Intel, 512MB Ram. I use Safari and MS Word. Today, after having the Mini for about 9 months, the screen occasionally goes black, and stays that way for about 5-10 seconds. It occurs every so often, like about once every 10 minutes. I have repaired permissions, ran Yasu, checked the settings on Energy Saver, where I have the computer on all the time; the display is scheduled to go to sleep when the computer is not being used for 17 minutes; these are locked. I haven't had this problem before. I'd appreciate it if you could give me some suggestions as to what might be wrong and how to fix it. Thanks, Jerry.

Thanks so much for your replies. I haven't changed the monitor from its original settings; made sure the cables are in firmly; I use cables for all my peripherals. I checked the Console and I may have had a Kernel Panic (I don't know, but it said something about Kernels when the screen went black). Moving the mouse didn't hurry up its return to normal. So, I again ran Yasu. I've been on the computer now for about 20 minutes and so far it's been working fine. I'm very grateful for your quick replies and for your advice. Hopefully, it's fixed now. Best wishes, Jerry.

Is there a setting for iphone 4 to have the screen dim to black while on a call?

If you put the phone to your ear, the proximity sensor darkens the display automatically. If you are just holding the phone in your hand or something similar, the proximity sensor is not activated.

My 13 in MacBook Pro screen randomly goes black. It was purchased in 2010. It's a 10.6.8.

My 13 in MacBook Pro screen randomly goes black. It was purchased in 2010. It's a 10.6.8. It started just recently. The only thing I can think of is is that my 7 year old son played an online game with the computer. I did check the "hot corners" settings and that is not the issue. When the screen goes black, I generally end of foce shutting it down with the power button.

My iMac is less than one year old. Without warning, the screen suddenly goes black. It used to happen occasionally, but is now happening all the time without warning. What is Apple doing to correct the problem?

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.

Droid Charge - dropping service, no incoming calls, screen freezing, going black...

This is my 4th Droid Charge. I've never been so disappointed. Nor have I ever needed one to work more. Not a good time to have a phone that just plain is not up to par.
This replaced a Fascinate, that I did not have problems with until Verizon did some sort of "download" on.
Ph #1 - literally acted possessed. Until the manager saw for himself after treating me like a mental case. ie "Well, set the screen time out for TEN MINUTES, if the screen keeps going black!" So he did & it went black, not to be "restored" without being turned off & re-started. Then, when it did "time-out" suddenly it went into V-Cast...no one was near it. It also would go into airplane mode...I could not retrieve voice mail; after entering the 2nd of 4 #'s, the screen went black.
Finally, it got replaced after then entire staff "witnessed" the phone I had to live with day in & day out. Guess the customer is always wrong....until proven time & time again, that the phione REALLY IS defective despite years of never complaining about a phone.
Ph#2 - I NEED the voice dial....I do. I travel in my work I have appts. If I am going to be late NEED to be courteous & call. While driving on the freeway, getting off & stopping only makes things ten times worse. While in the cup-holder, I can tap that....say who to call...and viola...BUT....it immediately says "Turn phone off" ...then try again. Well. how many times can you do that?? I mean really. How many times are you expected to turn your phone off for an app that comes installed ON the phone & should work. Right??
Ph#3 - Would NOT hold the signal...AND Voice Dial did not work.... did not back up info....messages did not come through, nor did phone calls. {even in the Verizon Store!! NO SIGNAL...they erased my phone for the umpteenth time!!! Grrrrrrr]
Ph #4 - arrived with YouTube loaded...to "How to Use Your Android Phone" !!!!!!!!!!!!!!!!!!!!!!!!!!! No kidding.
Screen locks up. Screen goes black & phone turns itrself off. Will not hold a signal...calls not coming through....
I saw others are also having these same issues. VERY frustrating trying to do "business" from a phone that is totally uncoopereative & unrealiable.
Very disappointed in this phone.

Steve, if the tech says get a replacement then that is what I would do.
But before I did, I would have them walk me thru a hard reset.
Sometimes that will help with ALL sorts of problems.
Godd luck!

Brand new Macbook Pro 15"inch laptop screen randomly going black

My laptop screen randomly going black during the use of computer, but the cursor is active and it moves with the track-pad. I bought this macbook pro 15"Inch laptop just 3 weeks ago. Did anyone come across this issue? Is there any alternative for this issue?

Hello Clinton
Thank you for your prompt response. I took an appointment with Genius Bar. Yes, this is a brand new laptop purchased it online through Apple website and received it on May 29th. I started noticing this issue from last week and it is happening at least 4 to 5 times in a day.
If this is really a hardware problem, is there any chance for laptop replacement or what will they do?
Regards!
Vijay

Try starting your iMac with the original DVD that came with the machine then launch disk utility to repair your hard drive.

When selecting the camera on 3gs the screen just goes black i can still take a photo using the top volume button but not with the screen please help

hello there
when selecting the camera on my 3gs the screen goes black and has no responce i can take a picture with the top volume button but cannot see it until i open photos
please can anyone help
thankyou andy

Try closing the Camera app completely and see if it works properly when you re-open the app : from the home screen (i.e. not with the Camera app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Camera app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work also do a reset (unless this is what you mean by powering off and restarting) : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
