21.5 iMac display goes black

brand new out of the box iMac purchased late 09... ran fine until i did the updates ... now the system acts like it goes to sleep but wont wake up. display goes black. restarts are iffy at best. i was able to get the system back up by unplugging for an hour and then restart. it did go down again. Hardware problem? or video driver issue? oh yeah ... display will flicker sometimes and seems dim also. any help appreciated.

Hi rjonsson;
I suggest you take it back to Apple and ask them to fix it. You really should not have to mess with fixing a brand new machine. Beside if this turns into a repeating problem you have started the documentation trail.

Why does the display on my 27" iMac keep going black?

This seems to be happening very often now. It started with just every once in a while.
I will be using my iMac and the display goes black. It does NOT go to sleep. Just the display goes black. I do video and audio editing on my iMac and if I am listening to playback or a song while the screen goes black, I can still hear it. So, I know it has not gone to sleep.
A way that I have gotten around this is by, once the display goes black I will then push the power button to make the iMac go to sleep. Then, I will push it again to wake it up. This usually works and the iMac will work just fine afterwards. Now what is happening, the iMac will go black again after a few seconds of being turned back on from sleep.
I tried to run a diagnostic with an Apple person over the phone and for some reason my iMac will not respond to this.
AND... It has gotten worse. I can't even boot up my iMac from a power down without the display going black.
Any help?

Apples update didn't work for me: Boot Camp: iMac displays a black screen during installation of Windows 7

Boot Camp: iMac displays a black screen during installation of Windows 7 - Apple Support
I have followed each of the steps listed in the link above with no success.
Prior to adding the extra drivers I was able to start the Windows install process up to reformatting the "Windows" Bootcamp drive. After that the computer would go through some instal processes and eventually restart. After the restart the screen would go black. The black screen lead me to the Apple Support link above dated March 5 2015. After going through steps listed in the link above, I get an error message stating that the D:\Sources\instal.win. file cannot be located. I am forced to restart the computer at that point and theWindows install process attempts to start again but always ends up at the same point.
Note: I am installing windows 7 Pro from a DVD. I scanned the AutoUnattend.xml file and noticed that it refers to "Windows 7 ULTIMATE" but not "Pro" or any others that I could see. (see below). Could that be part of the issue?
Any feedback would be greatly appreciated.

The File .wim will contains a compressed image which contains File [1...5].
The W7-Ultimate .clg will have 5 entries, with all set to 'Y'.
The W7-Professional .clg will have 5 entries, with 'Y','Y','N','Y','Y'.
The W7-Home Premium .clg will have 5 entries, with 'Y','Y','N','N','Y'.
The W7-Home Basic .clg file will have 5 entries, with 'Y','Y','N','N','N'.
This allows a single .wim Image file on the DVD media to be used to install any of the 5 flavors of Windows. When you enter your product key, the Installer knows what specific W7 variant you have the key for and will tell the WIM to extract the specific files the installer needs to be extracted.
The following line
<cpi:offlineImage cpi:source="wim:d:/sources/install.wim#Windows 7 ULTIMATE" xmlns:cpi="urn:schemas-microsoft-com:cpi" />
is telling that a retail product key will be entered, which should go look for this specific .clg file (from the five you already have on disk). You can test if it will work for you by changing this line to the following
<cpi:offlineImage cpi:source="wim:d:/sources/install.wim#Windows 7 PROFESSIONAL" xmlns:cpi="urn:schemas-microsoft-com:cpi" />
If it does not work, the other issue can be related to device discovery. Typically A: and B: device names are reserved for Floppy Drives. C: is your internal HDD.
D: can either point to the Optical drive, or the USB. The normal convention is that the removable media is named from Z: backwards. Y: and Z: are usually used for Network drives, so X: should be your USB. First try with the change to "Professional". If it does not work,

External Monitor with iTunes - iMac screen goes black

I have an iMac with iTunes 7.7/Leopard and an external VGA monitor (I use the standard Apple mini-DVI to VGA converter) then I use the external monitor to watch video from my iTunes library.
All works well - I have my desktop spread over both monitors, I fire up a movie from iTunes, move the video window across to the external monitor and everything is good - I can watch the video on the external monitor whilst continuing to work on my Mac - the iMac screen displays the Mac desktop as normal.
However, if I put the movie into fullscreen mode (view -> fullscreen on the iTunes menu), the external monitor displays the movie in fullscreen mode as it should, however the iMac monitor goes black.
The only way to fix this is to exit fullscreen mode and go back to one of the view options (rg fit to screen).
Any ideas how I can have my external monitor in fullscreen mode and have my desktop back?
Many thanks

IMac Display turns black

Hello,
The display of a friends iMac is going black. After changing the desktops color we saw that there are a few very light white vertical lines. Has anyone had the same problem so can advice us on what action to take ?
Attached a photo from my iphone showing the problem.
The iMac is a 27inch Late 2009 model with i5 processor at 2.66GHz with 6 GB of RAM. Model ID11,1.

You can start by using Mac OS X: Gray screen appears during startup - Apple Support. My advice however is you will likely find it less expensive to have a professional do any repairs. Most do-it-yourselfers in your situation end up realizing this after spending time and money fixing the wrong thing, bricking the machine or never finding the cause however the choice is yours to make. You can also attempt to run Apple's Hardware Test in extended mode 2-3 times back to back, if error codes appear then you know it's hardware however Apple does not publish the codes so finding out what the correct component is can be challenging.
Good luck!

Cinema display goes black upon resolution change in Windows XP

Greetings
Earlier today, I updated my ATI X1600 Radeon to the latest Windows Catalyst drivers and to the Catalyst Control Center from ATI. Even since, whenever a Windows application (games, in this case) tries to change the resolution on my external Apple Cinema Display (designated as the main monitor in the ATI Catalyst Control Center, with the MacBook Pro display disabled), the display goes black, and the monitor power lamp starts to flash.
If I unplug the external Cinema Display from my MacBook Pro, my MacBook Pro display activates, and displays whatever it is I was trying to launch, so the problems is somehow related to the Cinema Display, even if the new drivers are causing it.
This happens regardless of my Catalyst Control Center settings, such as scaling the lower resolution to fit the screen, or keeping it the original size, with black borders around. The problem does not occur when I launch games using 1600 x 1024, the Cinema Display's native resolution.
Any ideas what might be causing it, and how to resolve it?

Update on my situation: when I tried to change the resolution manually in Windows, I encountered the same problem. Now, whenever I connect the Cinema Display to my MacBook Pro, the same thing occurs: the screen goes black, and the power lamp starts flashing, even though I've changed back to 1600 x 1024.

MacBook Pro retina display goes black while outputting video through HDMI to external monitor??

I frequently connect my MacBook Pro to my 42inch Panasonic TV to watch movies/videos. I use VLC media player for all my playback. The problem I'm running into is that when I put VLC media player into fullscreen mode on my external display, my retina display goes black (I can still see the finder bar at the top and when I mouse down the dock appears but the rest of the display shows all black. If I click on Safari it will open but I can't see it on my MacBook display unless I take the external display out of fullscreen mode.
I would still like to be able to do things on my MacBook while video is playing. I've played around with the display settings but they're pretty limited and I can't figure out how to get it to work the way I'd like. I've seen people having up to 3 or 4 displays hooked up, I'm just trying to hookup one. I would consider this a severe limitation of OS X if I'm not able to separately manage the displays. Hopefully there is a setting or something I'm just not seeing. Thanks.

Yeah, fullscreen mode still doesn't play nice with multiple monitors. The common workaround is to stretch the window out to the edges of the screen instead of using actual fullscreen mode.

Hello QuinnDev,
Thank you for posting in the Apple Support Communities. It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on. I found an article that talks about closed clamshell mode. You would have to fulfill the following requirements to use your display this way:
Requirements for closed display mode:
Power adapter
External keyboard, mouse, or trackpad
External display
You can find all the steps and the full article here:

Run iPhoto slideshow on 2nd display without 1st display going black?

Hi there,
I can't seem to find a clear answer on this one. I have just connected a 2nd display to my mac mini via the thunderbolt connection. When I put iPhoto 11 onto the 2nd display desktop and run a slideshow it plays on the 2nd screen but my 1st screen goes black, which isnt ideal as I want to be able to carry on working on my 1st screen.
Is iPhoto 11 able to run a slideshow on a 2nd display without 1st display going black? If not, is there a way around this by using other software?
I have the 2nd display set up in extended mode not mirror.
I am running OSX 10.9.2.
Many thanks,
Andy.

Is iPhoto 11 able to run a slideshow on a 2nd display without 1st display going black?
No.
There may well be, but it's not possible with Aperture either.
Alternatives to iPhoto's slideshow include:
iMovie is on every Mac sold.
Others, in order of price:
PhotoPresenter $29
PhotoToMovie $49.95
PulpMotion $129
FotoMagico $29 (Home version) ($149 Pro version, which includes PhotoPresenter)
Final Cut Pro X $299
It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for.

Apple TV stops streaming via AirPlay when iPhone 6 Display goes black

Hi,
when my iPhone gets locked and the Display goes black (standby) after 2 Minutes, my AirPlay stream to my Apple TV 3. Gen stops playing. Only when i set the standby/lock time time to never instead of 2 Minutes (and the screen is on all the time) the Stream wont stop.
Sometimes the stream does not stop, wenn my iPhone Screen goes black.
This also happens with an iPad Mini or using an Lightning to HDMI Adapter instead the Apple TV.
I have no idea why.
Please help.
Best regards

Display goes black randomly

I purchased the notebook barely 16 days ago, and after a few days I noticed that the display goes black for a second or two randomly i.e it doesn't happen while holding the notebook in any certain way or something. The dislay goes black anywhere while playing games, music, videos or simply anytime. Also now there's some flickering in the lower part of the display. It happens with no approx time gap. I asked HP's Chat Support to help me out of this, they tried to uninstall and have a clean install of display drivers, that didnt work.Then they said they'll assign the nearest Physical service centre for an onsite visit and that some one will contact me, but waiting since almost 4-5 days this didnt happen. For the past two days I regularly ask HP's Support team about the promised visit but they keep on saying that today you'll recieve a call positively. The problem has escalated to such an extent that it interferes with my studies, work and daily use. This all has cost me alot of time and money and it's all due to your faulty product and carelessness. I would like you to help me in this regard, asap, if it is at all possible for you !! Edit : Before you ask, everything's updated to it's latest version. and I don't have an external Monitor.

Display goes black when in a call

I have noticed an annoying feature with my Nokia N8: The display goes black when in a call (holding the phone to my ear). When the call is finished I have a difficulty to close the call. Is this a Nokia special feature for saving battery that can be turned off or is it an error?
Solved!

Hey Is1987Is! Sorry you are having this problem.
It is normal behaviour for your screen to go black when held near your ear.
Is your screen just not coming back on once you finish your call or take it away from your ear?
Incase it is a bit more of a serious case of your phone having a black screen after hanging up a call. You can try this troubleshoot.
To make sure your proximity sensor is not over sensitive causing your phone to have a black screen, during incoming and outgoing calls aswell as alarms.
First thing is try to verify sunlight/IR oversensitivity with a typical desk lamp.
This could be done by making a phone call (or setting alarm) and putting the phone under the desk lamp when the phone is ringing (or alarm activated).
If phone is oversensitive to IR, display should go blank caused by IR radiation from desk lamp.
If this is the case you should take your phone to your Local Nokia Care Point, and they will be able to fix it for you!
I hope this helps, let me know if your phone goes black screen during an incoming calls when you test it under the lamp!
