My iMac Display doesn't work!
I hear the sound when he starts but the display stays dark! why?
Please Help me!!!
First, detach any peripheral devices except keyboard/mouse. Then reset the SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
If that doesn't change anything, follow the steps in this Apple note: http://support.apple.com/kb/TS2570 . When you get to the section on using Disk Utility to repair the disk, use Lion recovery mode by booting with command and R held down. Assuming of course by then you can view something on the screen. If the screen still doesn't work, take it in for service.

IMac - Display doesn´t work after restart
My iMac 21 Display doesn´t work after restart. If I turn it off and 1 hour later I want use it again the iMac shows the white screen with the mac logo and then the display goes off. I connected an external display to check if the iMac was ON and with the external display I can login and do everything but the iMac Display doesn´t work .
If I turn it off and wait 3 or 4 hours and then turn it back on the display works OK.
This is very strange behavior I have spent hours and hours trying to fine the solution or a similar issue but nothing so I am looking help here at apple.com
BTW When I bougth the iMac 21 there were some spots over the display so the display was replaced by the provider. The warranty has expired by now.To tell you the truth, I don't know if they have to repalce the LCD panel or what they do for a bad backlight. In this reality of block or assembly replacement it probably involves repalcing the panel and not the backlight component. Don't know what it would cost. You'd have to ask that of a service center.

Stand-by button on Cinema HD display doesn't work after Mountain Lion upgrade
Hi,
After I upgraded my Mac mini (spring '09) to Mountain Lion it appears that the buttons on the side of my Cinema HD display doesn't work. There is a setting in sys preferences that should put the Mac in stand-by when the power button is pressed. This doesn't work after I upgraded to OSX 10.8 Mountain Lion.
Does anyone have similar experience. Anyway to fix it?
Thanks,

Does anyone know if Apple have banned certain screens???? -
Apple Store said my display doesn't work but offered no solutions.
Just got back from the Apple Store. They confirmed my iPad is fine but the display doesn't work. It's black. Their only option was to pay $300 for a new iPad. Mine is only 88 days out of warranty and I took it in the store once already for the display issue that led to its ultimate demise. To talk to anyone else is $20. I refuse to pay more for a product that has shown itself to be unreliable. What's the next step? I truly feel wronged. iPad is in perfect physical condition.
I took it in in May of last year. The screen has black bars flash, the screen goes black for a moment, and then it comes back on. It can be days between the issue. When I took it in, it didn't do it. I had to wait forever even with an appointment. I didn't want to take it back in even though it has been having the issue all along. There was no way of knowing when it would happen. It finally flashed and never came back on.

New motherboard in GT680 - display doesn't work!
Hi!
I had to replace motherboard in my GT680. I've put ms16f21 version 1.2 in, the only difference between new and old motherboard is the version. 1.1 is used in GT680, and 1.2 is used in GT683. I've read somewhere there's no difference between these motherboards, so my GT680 should work with version 1.2.
And it turns out my display doesn't work now . Does anybody know what might be wrong? I've checked connections and battery on motherboard, and everything seems to be placed where it should be.
I thought it may be because of my graphic card. I've got 460M (standard for GT680), and GT683 usually have 560M. Do you think I might have to upgrade gpu too?
Ps. Please don't tell me it's best to ask MSI support, I wouldn't write on forum it that solved the problem .
Thanks in advance:)Quote from: SialeQ on 11-June-13, 04:51:09
Defective motherboard is quite likely, I just wanted to rule out any other possibility before I contact a seller I'll do one more test tomorrow, I'll put the old motherboard back. If it works, new board is probably damaged and I'll have to contact seller. If old board doesn't work either, then I messed up something when putting laptop together (or another component magically decided to die)
I'm not sure if MSI would replace it, I bought it second hand on ebay, and both warranty seals (on case & on graphic card) are broken :/
The seals being broken won't void the warranty, as long as there is no internal user caused damage they will cover it. I just don't know what the coverage is for second hand. -
IMac 17" Intel CD: display doesn't work
ciao,
today when I switched my iMac on the display remained dim, just like if it was off, while everything else worked OK.
so the display was black like it was off, but then I noticed that if I looked very carefully I could see the login box and I managed to log-in.
to cut the story short: the iMac is working OK but the screen is so dim it looks like it is off.
what can I do? Apple support chat told me to try to reboot the iMac pressing Command-Option-P-R, and that this doesn't work it is an HW problem: any other suggestion/reccomendation?
thank you very much

I5 27" imac display doesn't turn on
Hi,
This issue just cropped up for me this morning. When I go to turn on my recently purchased (Feb 2011) core i5 27" iMac, the screen doesn't turn on. Instead, it remains black until I hit the power button again, after which it will usually come to life. It sometimes goes black again without any warning. I can usually get the screen to come back to life if I hit the power button. However, I have an older 24" cinema display hooked up as a second monitor, and it always comes to life when I start up, and never goes black like the iMac display. Anyone else having this problem? Are there any known/recommended solutions?
Thanks!Reset the SMC > Intel-based Macs: Resetting the System Management Controller (SMC)
and zap the PRAM > Resetting your Mac's PRAM and NVRAM
Then if that doesn't help, contact Apple Support or your Local Apple Service Provider. > Apple - Support - iMac - Service FAQ

Hello everyone,
My macbook pro 15" suddenly turned off. Now i tried several time to switch it on and seems it is working but the display doesn't function or there are many wired pictures coming up sometimes.
can anyone please help me with this issue?
ThanksWelcome to the Apple Support Communities
Your Mac can't find any bootable partition.
1. Insert the Mac OS X DVD that came with the Mac and press C key while your Mac is starting.
2. Select Utilities > Disk Utility, choose Macintosh HD in the sidebar and repair the disk. If it doesn't work, take the Mac to an Apple Store.
Also, open > Startup Disk, select Macintosh HD and restart. Maybe your Mac has forgotten the startup partition -
IMac display doesn't turn back on after sleep
This is a new problem on my two-year old iMac, and didn't happen before. What is happening with my iMac is that when it goes to sleep and the display turns off, the display doesn't turn back on when I move the mouse, press the keys or the power button.
It happens only after around 12 hours or so of inactivity, it seems. I have to reboot the iMac to force the display to turn back on. I think it is display issue, not the computer lockup because I checked which logs were written in /var/log - system.log was being written until I rebooted the iMac. However, I didn't see any information in there around the same time that I tried to turn the iMac back on.
Any ideas on how to debug the issue.Hi dailyjoe
1. Reset your SMC exactly as instructed in the following article:
http://support.apple.com/kb/HT1543
2. It would be normal for you to have to startup your iMac if it lost power while in sleep mode, look at the box "Start up automatically after a power failure" in the Energy Saver preference.
I have always left the box for "Start up automatically after a power failure" unchecked and do occasionally find the iMac is shutdown because the power has gone off. I would suggest leaving the box unchecked, it's better than having the iMac going off & restarting multiple times if you are having bad weather or power issues.

Why Detect Displays doesn't work anymore?
I use my PB to watch movies using my TV and the S-Video to RCA cable, but since the last upgrade 10.4.6 the Detect Displays option (in display menu bar AND preference pane) doesn't work.
The TV shows a dimmed image of what's suppose to show and sometimes it appears vertically distorted.
I disconnected the S-Video cable and restarted the PB but it still shows that "something" is connected to the s-video port.
Which files should I delete to "reset" video preferences?
UPDATE: PRAM reset didn't work...
Thanks in advanceWell, the cable can't be the problem, because the computer is "stuck" with a two monitor configuration, even without the cable plugged in, that's why im guessing there's some kind of switch (i hope) that i can reset so the mother board stops thinking i have another display plugged.... the second problem is that if i plug the s-video to rca cable (that came with the laptop) i can't get a clear tv signal from it... it's distorted.... i'll probably open up the computer and check the s-video port... wish me luck.

Question Mark Folder on start up on an iMac; USB "doesn't work" unless...
I am having a very difficult time with an old Indigo iMac (slot-loading). The symptoms are as follows:
Blinks between Smiley Face and ? on start up
Keyboard doesn't work unless in the Developer mode(? mode with the white screen and some command options. I think it's developer mode...)
I do not know what to do really. Even using alternative methods to try and get the computer to boot such as hooking up another drive from a different computer to it via an IDE to USB and trying to get it to boot, but to no avail. Is there anything I can do in the Developer mode that would help?
Power Mac G3 800 mhz Mac OS X (10.4.2)Hi, Lezard -
If it is a 333MHz model, it is not a Slot-Loading model; it is one of the last of the tray loader models (designated as the Five Flavors models), as indicated in the right-hand column for that model (fourth one down) in the KBase article you linked to, Article #58669.
In that case it is not USB bootable.
Is there a way I can possible change the start up disk through Open Firmware?
Not that I'm aware of - Open firmware is not that flexible.
Have you tried booting it to an OS Install CD, one valid for that model? Such would be the original Software Install CD that came with it (OS 8.5.1), or any retail OS 8.6 or OS 9 Install CD. If you can get it to boot to a CD, you can change or reset the boot volume using Startup Disk control panel.
Also, if you can get it to boot to an OS Install CD, run Disk First Aid from the Utilities folder on the CD - let it have a look at the drive, and repair whatever it can.
While booted to the CD, take a look at the System Folder on the hard drive - does it show the Mac OS glyph superimposed on the folder's icon, or is the folder icon plain? If it is plain, that System Folder is no longer blessed, which is relatively easy to fix.
Note - when using keyboard startup commands, for most of them be sure you press the key(s) early enough, usually about the time the startup chime sounds; and keep them held down until you are sure the command has been accepted or been invoked. -
MacBook Pro display doesn't work
Hi everyone,
My MacBook Pro's display has been working erratically in the last weeks.
The first time, the display did not work for two day. Second time for almost a week (during Easter) and now for three days.
I've never had any hardware related issues with my old Apple computers, so this is very strange to me.
I've already followed the instructions posted here: http://docs.info.apple.com/article.html?artnum=300537
The computer seems to work normally, I can hear the startup chime and the drive spinning if I get close to the machine. The problem is the display or the graphics card.
I am in Peru at the moment and contacted the local Apple Reseller and they've told me it takes approximately 60 days to have it repaired. I'm thinking about flying to the US to have it repaired quickly, I can't wait that long.
My Mac's specs are:
MacBookPro3,1
Intel Core 2 Duo 2.4 GHz 2 Cores; 4MB L2 Cache; 4GB RAM; 800MHz Bus Speed;
Boot ROM Version: MBP31.0070.B00

Has anyone had a similar problem? Were you able to solve it without taking it to Apple?
Thanks for your help!

Message was edited by: YoQuieroTacoBellI am going to chime in because I had the problem, did an archive and install which fixed the display problem but a display issue is back again! When I did the Archive and Install, I purposefully did NOT install the graphics update. That fixed the issue until yesterday...... I think the monitors worked alright when I started up in the morning but later in the day, I noticed that the external monitor (SyncMaster225BW) was a yellowish color and the letters were distorted. Ok, so I unplugged it and previously when I unplugged it (since the Archive and Install anyway), the MBP display would go blue but come right back on. Not so yesterday. It stayed blue so I had to press the power button to get it to go off. Booted up and came on. Plugged the external monitor in (can't remember if I plugged it in while it was shut down or after) and it worked fine. Booted up this morning and the resolution and color on both monitors was yellowish and not right. In fact "mirroring" was turned on, something that I did not choose. Recalibrated my MBP monitor. Got that right. Oh, and yesterday and today, I had to choose my background pictures for both monitors. Couldn't get the external monitor to work right so unplugged it which caused the MBP monitor to go blue and stay blue. Had to reboot again. Left the external monitor unplugged. Started writing this post and plugged in the external monitor again and all is right. Both have the correct background picture and resolution and in the menu bar, both are listed with the correct names (first thing this morning they weren't named Color LCD and SyncMaster). So anyway, that is my display woes. I was so happy that all was well after doing the Archive and Install and not doing the graphics update but something else is going on now. Not sure what. Hope this issue gets fixed soon! Please Apple....... Judy

Mac book display doesn't work anymore
I normally use my mac book 2011 with an external display. However, for the past few days, the macbook display is not working. The computer boots up, but will only display on the external display with the lid closed. How do I fix this?
Thanks for replying.
Are you referring to an F2 key on the MacBook? As in, "did I try brightening the MacBook display"?
If so, yes I have. If I. Completely darken (F1 key) then brighten the MacBook display using the F2 key, I get the same less-than-one-second result before screen blanking. The display is actually still there, but completely inlit. -
Display doesn't work after latest security update
I have three Apple displays with my MacPro, and after installing the latest security update, one of them just stopped working.
The status light is still on, and my usb devices connected still function, but I have a black screen and nothing is recognized in the displays system preferences.
Anyone else experience this? Did my display just die?Ut-oh!
FWIW:
My 7-year-old 22” Cinema Display, on a 10.4.11 machine, with nearly constant use, now becomes so dim during the screen saver mode that regardless of which saver I use, it becomes no longer visible.
As soon as the screen saver is activated, I have full brightness (though not as bright as when the display was new), then it gradually fades until the screen is all black.
Upon awaking, the screen is very dim, and then, over a 90 second period, it slowly returns to normal brightness.
1. The brightness control is set to max.
2. I have toggled the brightness control and changed screen savers, both to no avail.
3. Recalibrating the display did not work.
This seems to have occurred on the same day I installed the latest Apple Security Updater.
Very weird...
