Intel Mac :: 27 Inch Screen Won't Turn On?
May 11, 2012
my imac is about 3months out of the box and a few days ago i went to turn it on and....nothing. i could hear the start-up chime and the mac clicking and making "doing" noises, also i could clearly hear the volume toggle up and down. That said, the screen remained, well, dead and just black.So, the first thing on my agenda for the weekend was to take my imac into the shop. As i was organising the equipment, i tried one more time to turn it on.It worked.For me, that's a bad thing as my mac may do this again. It was out of action for 3 days now it's back. So now i am on here.

I have a 27" iMac. Just recently, the screen has begun to randomly shut off. I then have to squeeze the power button, followed by a click of the mouse. This will bring me back to my password screen. Sometimes, that would be it, other times, it will do it repeatedly, for no reason, and then settle down.
Just for those of you who are bound to ask me about my Energy saving settings: Computer to sleep – Never. Display to sleep – 15 min.
It seems to me that this could be a hardware issue, but just incase any of you have had any experience of something similar, I thought I would ask.

I just received my 21.5 inch imac refurbished. It is the 2011 model. I really like it, but the screen seems to constantly be adjusting brightness...Almost as if it is "flickering every 5-10 seconds. It is extremely annoying, and I think I will have to return it to apple. So another two weeks of waiting for a computer.

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.

For three weeks now, the windows on my desktop turn blue and separate when I click on a link or open another window. I had the hard drive replaced; Apple diagnostic found nothing. Accidentally discovered it happened when I used my mouse. Scroll only worked forwards, not back or to the side. Replaced mouse with new, identical model. Still happens. Then I used an old mouse from 2003, no scroll wheel, but it seems to work fine.

My Imac---which is less than a year old--randomly goes black but continues to function otherwise. This is happening on a more and more frequent basis.

My parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.
I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.

Most of the time when I turn on the Mac I get the white screen and question mark appear. Sometimes it will turn on and work. But often the coloured spinning wheel starts up especially after trying to use iphoto it freezes and a couple of times the screen has then gone black. The computer seemed pretty warm yesterday when this happened.

Apparently there might be a way to convert the HDMI to a miniDV display.
Is this really possible?
Has anybody really achieved it?
What kind of cable/adapter do you need to buy?

Does anyone know if it's possible to use a 24 inch iMac as a Target Screen? I know it's possible for 27 so there must be a hack or terminal command line that I can enter to achieve this.

I was using my computer and it was just fine. I closed it carefully (as always) and left for a few minutes. When I came back and opened it up, the screen was completely pixelated. I turned it on and off and read several forums and tried cleaning the drives and nothing is working at all. As I've been working on it parts of the pixelation of bright colors have begun flashing a little bit. Not a lot but a little. Black doesn't seem affected by the pixelation but you can see lines in the white areas. Also when images are fading in and out, they don't become pixelated until they are at their brightest. When they are fading in and out they appear fine.The graphics card in my computer is a Nividia GeForce GT 330M. SO I'm guessing from this that the graphics card is damaged or whatever. I can't afford to have apple repair it for $400 and the nearest apple store to me is two hours away.

My daughter has dropped her ageing MBP, bent the screen lid and now the screen is no longer usable. We have other Macs available to access the data on the screen if we could turn on Screen Sharing on the damaged MBP running Snow Leopard.

Computer starts (keyboard lit, music plays, caps lock light on), but no screen. I need to open and close 2 - 30 times before the screen will turn on. Once on, the computer works perfectly. I've tried PRAM and safemode reset.

The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?

My lovely cat recently decided to walk around my desk while I was at work and knocked over my Imac, causing a large crack in the glass and the screen. I'm not technically capable enough to do the install of the screen/glass myself, but I was wondering what I should expect a repair from an Apple certified technician to run.

I just got a mbp 2.26Ghz 13inch
with screen model 9C9E
I've read some got screen model 9C9F and more.
But I find my screen is not very impressive at all
infact, I think it's not much different form the UMB.
is there any difference between the 2.26 & 2.53's screen?
and some with the same 2.26Ghz model yet having different model of screen of different screen quality.
Yet mine have a bad color saturation as well as a very low brightness.
