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.
Some weeks ago the screen on my iMac started to go blank. The only way to recover was to re-boot. The problem got worse until the machine became un-usable. I tried everything I knew, including switching off and unplugging to reset the pram as suggested, but eventually took it to the Apple Store where the 'expert' reset the pram the old way holding down the cmd/opt/p/r keys on startup. Problem solved (why do Apple give bad advice to clear the pram?).
Something had corrupted the software that drives the screen. The only program that I could think might have done that was ScreenRecycler which I have now stopped using. However, the problem has started to re-appear, the only new program I have used is Audirvana which being a music program should not affect the screen.

During an upgrade, power was interrupted and when rebooting, the chime sounded, but screen remained gray.

The latest iMac model. When I click on the power button: I can hear the Hard disk and the DVD drive spin up. The screen stays black. The startup sounds plays half way through the first time, like its being cut off. After the first startup chime has been cut, the chime keeps playing in a loop. The computer doesn't come any further than that.
I have tried: Unplugging all peripherals, with the same result.
SMC reset: Unplug power cord and hold power button for 5 sec. PRAM reset...
It seems like the computer does not even get to boot and ignores all keyboard input. I also tried booting from the DVD drive with the installation disk. But I can't get any further than the repeating startup chimes.

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.

Some time today, my iMac started displaying some type of outline in the background. I bought it in December, and I've never had any issues with it until today.What the outline is? I heard it might be dead pixels, but I honestly have no clue. I just checked the screen again and it's normal now.

View 1 Replies View RelatedNot 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.
View 1 Replies View RelatedI 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.

I have an Intel IMAC, which is now out of warranty as I have had it for 16 months (and I was dumb enough not to get AppleCare). A few days back, my computer would not startup and everytime I hit the power button, I would hear some spinning noise but no chime from the iMAC. Yesterday, I tried it again and this time I heard the chime but the monitor did not start. I was then able to SSH into the MAC and see that it is indeed connected to the network and booted up, but the screen is still dead. Any ideas what I should do before the painful trip to the apple store ?
View 2 Replies View RelatedFor some reason, a friend of mine is having issues with her new iMac (one generation back). Here is what she emailed me about the situation:
Here�s what happens in greater detail. I quit or force quit all open applications. I press the ON/OFF button until the screen goes black. I wait several minutes and press the same button ON. I get the Apple cord sound and a blank white screen. The Apple icon does not come on; nothing happens. That�s when I close it down again and disconnect it from the back and reconnect it (a few seconds). Then I press the O/F button and the Apple cord sound AND the Apple icon come back, the system revs back up. All all is well � except for the ball coming back...
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.

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

Our iMac is starting up.....I can hear it loading. However the monitor screen is completely blank/dead with no backlight.
This has just happened. I have switched it off and unplugged from the mains before trying again but no luck!Â

Just got the new iMac quad core i7, purchased Windows 7 Home Premium and having trouble getting it to install using Boot Camp it goes through all the steps I partitioned 350 gig then formatted went thorough the install steps, it reboots and finishes the install, then reboots but nothing happens its just a black screen
View 3 Replies View RelatedI 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 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.

So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.
I have just got an old 2004 G5 and thrown a brand new hard drive in it. When i tried to install leopard (which I'm told would be the best operating system to use) it comes up with a blank blue screen!

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

I just replaced my LCD. It was working fine, but now just stopped working. It's a mid-2009 A1286 15in Macbook Pro.
The computer itself works fine and I tested it using an external monitor. I can FAINTLY make out the display on the screen, so I'm guessing it is a backlight issue? Don't mid-2009 don't have display inverters?
I also tried resetting the pram and SMC.
I am having a problem with my 2009 Mac Pro. It fails to boot. There is no chime and the screen wont turn on;stays black. It wont boot off of the system dvd and I even tried installing an HD that has a good version of the the OS on it. I also tried booting from the DVD with no installed drives to rule out one of the internal drives doing someothing funky. Nothing happens at all, the HD or DVD will spin for a moment and then all is dead.
