i - hope someone can help me diagnose this fault.

Imac 27" late 2009

Was on Mavericks - now new HDD and reinstall of mountain lion

The fault was present before the HD and reinstall of OS

I have disabled sleep and HDD shut down etc.

So, if the mac goes into sleep mode either automatically or if I click on sleep, it will not wake again with mouse or keyboard, bluetooth or wired.
If I shut down holding power button and restart it "sounds' like all is working but black screen.
I have to switch on and off a number of times then hey presto normal grey screen and boots up fine - all works great until I shut down or put into sleep mode then here we go again.

I have reset SMC/PRAM etc

Tried to run with diagnostics mode D or shift D on start up but can't get that to work - also a bit awkward because sometimes the screen starts black ....


I am thinking its not software due to new HDD and reinstall of OS

Graphics card?? Display??



Please help

Could be several things, but most likely hardware.

I doubt its the graphics card or the display, more likely its an inverter board or a LCD driver board.

Best option is to have an authorized Apple repair person take a look. They have more advanced tests that can pin point some of the hardware issues. (Apple store isn't the same as authorized repair professionals )

I have a 2007 iMac with identical symptoms. The cost of a inverter board for that old of an iMac wan't worth the hassle and it wasn't guaranteed that it was that. (I read issues about iMacs not getting a "heart" beat signal from the motherboard that would cause that too.)

The cheaper option was to get a display port adapter and cheaper LCD and put it in front of the iMac.
Not nearly as nice a LCD, and aesthetically not nice, but viable option for an older system.

Thanks Headrush - yes I tend to agree with you. I think I have run out of techniques to use to dig at home. Just a thought, when the screen won't come back on it appears as is thing are working in the background - fans spin hdd spins but keyboard docent seem to work, in that i assume if all is working it is taking me to the login screen - I am typing my password (blind) and hitting return but no noticeable change in sounds form the machine i.e. hdd no change etc, I would expect some sort of impact ...?
Ultimately I think your right though I need an experienced engineer to dig. Any other thoughts welcome...cheers

If you can get the screen to come up one more time, turn on screen sharing.
Then, if you have access to another Mac, you can log in over the LAN in and verify that everything is running as expected.

Hi Headrush - tried the screen sharing thing and guess what, all is working fine except screen - in that on the screen mirror I can log in etc but display stays black on main mac. Funnily enough when in mirroring mode i can click out of sleep on the black screen mac as normal - makes me think about this heartbeat issue, almost as if the mirroring function is giving the system a nudge to keep listening for the keyboard to wake it...? From cold though still takes between 3-5 times on/off to get the screen on.
So not sure where that leaves me - probably back to an apple workshop - however, this time i got an error log with sleep failure - way beyond me but any idea where best to post this for help .....Thanks again

Mine did the same thing, though it progressively got worse over the months to the point I just went with the external monitor.

I'll see if I can find the original article on the heartbeat thing for you.

Hi - I still have this irritating problem with a black screen - on turning on my iMac 29 late 2009, the screen is usually black - appears to boot up but clearly unusable. Only way I can resolve is to turn it off quickly (before accessing the HDD, then turn it on - if i do this 2-5 times the screen will "kick in". Please help

hi - well have now stopped the machine going into sleep during norma operating so once it is on all is fine. however, when i startup it takes 3 on/offs before screen kicks in. If i leave it on black screen i can log on via my other mac and see all is working but can not get the screen to come on.Seems like hardware to me???

I bet if you take it to Apple authorized repair place they will say inverter board, or LCD driver board, or both, but fixing may not solve the problem as per that article.

When mine got too bad I disconnected the internal LCD so the external was the default always, and got an external LCD that had a removal back and I "hung: it on the iMac using s snapped bracket I cut from wood.
