Intel Mac :: Screen Blank On 27" Mid 2010?
Jun 5, 2012
Recently my iMac display goes black in the middle of using it. Initially I thought it froze up and I had to force it to reboot. But after this happned a couple of times I realized that I could stil hear the hard drive working and my peripheral lights (keyboard, etc) were still on. On a hunch I put it to sleep (Option-Cmd-Eject). After it goes silent I can press a key and the display comes back up and everything is normal (for a while).Â
It's now been doing this regularly for the last 3 weeks. Sometimes three or four times a day this occurs. When the screen goes black nothing seems to work except the sleep-wake thing. I've tried the screen brightness keys too - but that doesn't work either.Â
My software is up to date (Lion 10.7.4). This is a Mid 2010 iMac 27" with 12GB of RAM and the ATI Radeon HD5750.The regular software that I have running is:
Chrome
Forklift
Light-room 4

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.

When I turn my computer on nothing happens. You can hear the drive or cooling fans but there is nothing on the screen. Normally there is the spinning wheel but now nothing.

A small (about 1 inch square) blank, white box has appeared at top left-hand corner of my screen. Nothing seems to shift or remove it - cursor doesn't seem to recognise or register on it. I first noticed it soon after I'd had to re-start the Mac (it failed to 'fire up' as usual the other morning), but I can't remember exactly what I was doing when I first saw it.

I restarted my mac this morning after the time was broken (as far as I know, I cannot manually change it). When it booted, it booted normally. It logged me in (I am automatically logged in) then it threw errors at me. The 2 errors were from Steam and Skype, but none from the mac itself. Steam error: " Steam failed to load: *SteamStartEngine(0xbfffdea4) failed with error 1: Failed create pipe: 28". I forgot to record the skype error, but it was something to do with it not being able to find a file. At this point, the background is blue, I can see the top bar but not the dock. I then close Steam and Skype windows and the bar disappears leaving me with nothing. A blank blue screen. The dock wont come up.Â
I would take this to support, but they want a serial code that i cannot access because its not on the hardware and I cant access 'About this Mac" because it disappears.

I did a pram reset but that did nothing (I heard the initial chime and the one after the reset....still the same problem.) I'm a bit worried because I don't hear the hard drive starting up.
Some more info... Intel Imac 17" (late 2006 model), 512 mb of RAM, running 10.4 (I think). I am not familiar troubleshooting macs but I am troubleshooting PCs.

I have a mid 2007 iMac that seems to, for no apparent reason at all, just randomly go to a blank screen, locking up my Mac requiring a hard shutdown. This happens sometimes right after I start it up or after I'm on for hours at a time. Or not at all, I simply don't get it. I reinstalled Lion (after I redownloaded it to be safe) and it didn't seem to work.

My daughter's old I Mac won't start. It is not backed up. We want to get some things off of it if we can. When we turn it on, we get the Apple logo with spinning wheel for awhile, then a question mark briefly and then a sky blue blank screen. Is there any hope of getting this to work? This computer is out of warranty. Does it seem that if we reinstall the Operating System we might find old data? Â

Today I have noticed that the screen was dirty while developing photos. After cleaning, the screen was still like this, so I'm afraid it is a permanent issue. I think the photo is self-explanatory.Â
I have increased the contrast in order to see the problem more noticeable.Â

I've had the new macbook air just two days now. Turned it on this morning, used it for like 5 minutes and the screen just started flickering, and the whole machine just froze on me! Had to do a system reset, but I'm a little concerned after spending over a grand on this macbook! Has anyone else experienced this? I'm actually thinking about returning the machine..

When finished, I normally put my mac into standby mode instead of turning the power off. Last night, I did the same. When I tried to power on today it seems like my mac is working (the buttons beep when pressed and hear the hardrive), however, the screen is blank (never turned on). I believe if I can actually turn my mac off and on again it may fix it, however, I have already tried taking the battery out and putting back in to no avail and I think everytime I try by pressing the power button it goes into standby mode. Is there a way i can force my mac to turn off instead of going into stanby mode by pressing certain buttons since I can't see the screen?

Got this mac friday but haven't really played with it before yesterday. My problem is:
1) Yesterday I went for logging in to facebook, but suddenly the screen went green? Had to close the mac down and start it again.
2) After I had turned it on and was on the desktop the screen (with me doing nothing) went white, and I had to do the same again.
3) This morning when I wanted to turn the mac on, it wouldn't! But few hours later I tried again and there I could turn it on by pressing esc + start button.
Should I call for a replacement? (Already had two - 1 with dead pixel and 1 with creaking).

1 month past warranty expiration and now my screen goes blank when I adjust the angle. Is this usually something major or just loose connection?

I was using it in my bedroom, it was plugged in. I went to make some food, and upon my return I am greeted by a blank screen, probably just a hiccup right? So I held the power button down expecting it to spring back in to life. But it didn't. It wouldn't turn back on. At all. Luckily, I thought, I have my old 2006 Macbook that I keep as a back up just for times like this. As it hasn't been turned on for a while, the low battery warning comes on, so I plug it in. 10 seconds later, it hibernates. I switch it back on, but it keeps hibernating for no good reason. So I think restarting it will solve the problem. It didn't. It too, now wouldn't turn back on. At all.
In the space of a few minutes, they both completely died. I've tried resetting SMC, PRAM, everything I've found on Apple's support page and forums like this. Nothing has worked. The light on the power cable glows orange when plugged in, so it is still charging, and the battery indicator lights on the side of the MBP work fine. Aside from that, they are both completely lifeless...........

I've got a 15in aluminium powerbook, a couple of years old. So far I've had nearly everything go wrong with it. replaced screen, knackered hd, ram port failiure, and a battery that lasts 10 minutes.
I recently replaced the harddrive, as the standard issue one packed up a few times. I followed the instructions on ifixit.com website. To my delight I actually managed to do it, and the pb worked well for a few weeks. Then suddenly, the screen froze and faded to white. So far I've tried everything -
Resetting the pmu. Resetting the pram and nvram. Opened it up to check I reconnected everything.
and checked to see if the hd is still working starting it up from another computer, and it works fine. Everythings still there. Someone also said if you hold 'R' key down on start up it resets the lcd.
BUT STILL BLANK!!!!!!!!!
The screen still seems to turn black after a little while, indicating the energy saver is still on. I'm thinking I may have dislodged an lcd connection or something?

I have a problem with my mini/quicktime setup and i was hoping for some help from you all at macrumors...
Here is the setup
This system is setup for a admissions office in which we have a mac mini set up to a LCD screen that is all mounted on a wall.
we have the mini on timer to come on from 1230-5pm and when the mini comes on, quicktime is set to automatically open and play the admissions video.
Now here is the problem:
when I turn on the LCD every day, the screen is blank but Ican still hear the video, I figured it was in hibernation so i move the mouse and hit the keyboard and nothing. i need to push the power button and hold it for a couple seconds then the movie comes on but the video is choppy.
here are the specs on the mini: 1.25 power pc G4, 512 Ram.
its old but its only function is to play this video...

when I turn on my computer there is a blank screen. You can still hear the normal noises coming from the computer like any normal boot-up. But if I let my computer sit for a while without turning it on, it will turn on with weird almost static noises. If I force shut down then try again, I get the normal boot-up noises. I tried the safe boot-up method,holding down the shift button while turning the computer on, but no dice. I actually tried this method on both the good and static noise boot-up.

I am trying to set up boot camp on my new mac mini. The primary reason is that 10.6 intel macs don't support my version of mac photoshop (Photoshop 7). I have an XP version of photoshop installed on my old laptop, and want to boot XP on my mac and move it over. However, when I tried to install Boot Camp, and re-started with the windows CD in from Boot Camp, I had a gray screen for a bit, then a blank screen.
I have a brand new Mac Mini, with OS X 10.6, and I set up the boot camp partition successfully. My windows CD is XP with SP2 as apple claims is required.
Additionally, I have an external hard drive with a .bkf file on it from a backup of my old PC laptop that has photoshop in it, but I can't extract that to my BOOTCAMP drive, at least without windows already installed on it.
I tried some other windows CD's, and a windows DVD that are supposed to be bootable borrowed from friends, using the boot camp application, with the CD in, at least XP SP 2, and I still got a blank screen as it re-started, and thus have been unable to install windows.
Is there another way I could install windows? Perhaps from my .BKF file? Is there something I might be doing wrong? I do have an older monitor, a viewsonic 17 inch, and I'm using an apple adapter. Could it be that windows install CD's don't support my graphics card? If so, how am I supposed to install windows? Also, my keyboard doesn't seem to be recognized either. It is a macally ikey extended keyboard, and I can't even get the caps lock light to turn on while it is trying to load of the windows XP disk with boot camp.

Not even a week old!! Computer was asleep for about 2 days, woke it up the same way with a few taps on the keyboard and it just started to beep. Tried to turn it off but nothing. Nothing on the screen, just beeping. Pushed the power button and beeping. Unplugged it and waited 5 minutes and pushed power button and beeping with nothing on screen. Its sunday and it hurts my stomach to think about the lengthy process this will be to get a new one or get it fixed. My wife says to call, but I tell her that if there even isn't anything on the screen then what can they do over the phone. Is it possible the memory went bad. What would cause this? Its plugged in a power strip.

I need your opinions; since the 10.6.3 update my iMac has begun to freeze to a blank screen. I think this may be a sign of a dying logic board, however I question this as I don't have the freezing problem with 10.6.2. Picture of blank screen attached.

My Mac Pro arrived today and of the six or so times I've restarted this has happened three times:
I get the normal grey Apple logo screen then as it switches to the login screen the screen goes black. The monitor doesn't go into sleep mode, it thinks its getting a signal. If I hit the power button and put the Mac to sleep then wake it up the login screen appears.

I had a power outage while the computer was running, and now whenever I try to login as my admin, after the password part it just goes light blue. Full screen blank out. I can use my non-admin accounts and use the admin password to change permissions.
