Apple Cinema 23" & powerbook - staying black forever

Hi,
I'm running a powerbook G4, and have a 23" cinema display screen.. along with the necessary DVI to ADC converter so it can plug into the powerbook.
I've run it on this computer before fine.. but the last 2 months its been running on a PC, which now i've swapped back to this mac.
Only thing is, the screen won't turn on. I push the power on button, and it just fades away. The powerbook does detect the screen and all, and when i hold down the power button and click 'detect displays' it finds it.
But it still won't turn on! i've tried restarting the computer as well, and it still won't work!
Can someone please help
Thanks
Scott

Hi Scott,
Welcome to the discussions.
Have you tried putting it back on the PC? What happens then? (I'm thinking your adaptor may be faulty).
Cheers!

MacPro & 30" Cinema Display - Display stays Black at Boot/Will not light up

I just rec'd a MacPro 3.0GHz/8GB/4-500GB and a 30" Cinema Display.
After connecting all of the cables, when I start the Mac, the display remains black. I have also tried another video card and a 23" Cinema Display as well.
The indicator light on the display blink 3 times, and then a short pause. I have reset motherboard, pulled all ram and re-inserted, and swapped video cards and locations.
I have a wireless keyboard and mouse, so resetting PRAM is out because I can't even get to the Register Bluetooth Device screen!
Any ideas on getting things started?
MacPro 3.0GHz/8GB/4-500GB Mac OS X (10.4.7) MacBookPro 2.0GHz/2GB/160GB

The primary card is the std 7300. The other card is an NVIDIA Quadro FX 4500 (PCI Express) from a recently purchased Quad 2.5 G5, that Apple said is compatible.
I have tried the cards in all onfigurations and in all possible slot configs as well, utilizing both DVI ports for each trial.
I have pulled/re-inserted the RAM, and all cable and drive connections.
Still get two short and one slightly longer blinking indicator light on the display, whether the Mac is powered on or not.
Both displays work with other computers attached.

Mac Pro 2008 Apple Cinema Displays are black and there are start up issues

I have a Mac Pro 2008 Dual quad 2.8 GHz. I have two Apple Cinema Displays (graphics are the standard ATI Radeon HD 2600 – 2 dual link DVI. I have 4 2-GB RAM sticks (8 GB total).
Neither of my displays are showing anything. Their power lights are on but they are completely black throughout the start up process. In addition when I try to boot up with both graphics cards installed, I get nothing – no beeps no chimes. If just one card is installed (either card in either slot) the computer beeps, chimes and makes the sounds of booting up, but not a flicker on the displays. RAM does not seem to be the issue as I have tried booting with several configurations of RAM sticks with no negative or positive effects. I tried booting up with Hard Drives 1 & 2 removed with no effect. I have tried several different start up moods and have reset PRAM.
My guess is that there is something wrong with the motherboard. Or is it possible that both graphics cards are bad?

The "least intensive" thing you can do is hold down Alt/Option at Startup. Thsi invokes the all-in-ROM Startup Manager, which will light up the screen gray or blue, then attempt to draw an Icon for each potentially-bootable Volume attached (if any). It works as if in slow motion, so you must be patient. If no activity after about two minutes you may count that as a failure.
The next most intensive is to attempt to boot from an incorruptible source of software, such as an Installer/Utilities DVD. This again uses the "one-size-fits-all" display driver, and attempts to load software off the DVD. The dark colored Apple is loaded off a drive -- it is not present inside your Mac.
The next most intensive step is to attempt to boot into Safe Mode. This also uses the "one-size-fits-all" display Driver, and does a disk check as it starts up, adding five minutes to the startup time. It then drwas a login screen and deamds your username and password, even if you normally auto-login.

20" Apple Cinema Display not recognised after upgrading to OS 10.8.2 (Mountain Lion)

20" Apple Cinema Display not recognised after upgrading to OS 10.8.2 (Mountain Lion).
Hello Apple! Anybody there? How long does your community have to wait for a solution?
The same problem has been unsolved for months now. No statements from Apple either.
I was told today to wait for 10.8.3. This might solve the issue. I can not belive my ears.
My MacBookPro 4,1, Intel Core 2 Duo with 2.5 GHz Processor and Graphics chip: NVIDIA GeForce 8600M GT, will not talk to the exter. 20" Cinema Display ( Model Number A1081 ). The screen stays black. Resetting the PRAM did not help. I removed the 'com.apple.windowserver.plist' and the 'com.apple.windowserver.OE35739etc,etcxxxxxxxxxxx.plist', but that did not help either.
Any other solutions, or do I have to downgrade or give up on Apple Computers alltogether after using them for over 25 years?

I found out that I needed a $100 mini displayport to dual-link dvi adapter to make my $30" cinema display work with my macbook pro
http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter?fnode=51
When I found out that solved the problem, I took it back because that was too expensive for a stupid adapter, and it still didn't work perfectly.

Apple Cinema Display

HI. I have a question. I am replacing (finally) a MAC G5 PPC with a MAC Intel (tower). I have 2 Apple Cinema Displays - a 20 inch and a 23 inch. When I migrated everything from the PPC to the INTEL, I hooked up one monito to each cmputer. Good. All fine and dandy. Now, I shut everything down and I want to connet both Apple Cinema Displays to the new Intel. However... the new Intel has DVI pots and only one PIN port. Ok..so I went and bought a MINIDisplay to DVI adapter. Now.. here's the problem:
When I pug in both displays, the bigger 23 inch stays dark (although the power is on)...but it takes OVER as a primary display! Which annoys me because now I cannot see my desktop...only that is in he secondsary monitor... So I went to System Preferences and tried the DETECT DISPLAYS.... it only shows one. However when I go to GATHER WINDOWS.. I see TWO blue icons that symblize displays. My bigger display..still dark. I tried resetting the PRAM...nothing.
I'm wondering if all of a sudden my biggers display gave out? I mean..it was just eralier today that it was working. Oh...and one more thing: if I do not use the 20 inch and plug in ONLY the 24 inch... still dark.
Help. (my mac is Intel Tower running on Mac OS 10.7
Many thanks in advance.
PS I now see two window displyas when I say DETECT WINDOWS One is 1920x1200 (which I assume is the 23 inch) and the other is 1680x1080 (which I assume is the 20 inch). So I would think that the system preferences can detect these two monitors, but why is my 4 inch black??? Did it fry>

Solved it. I am an idiot. It was the power unit. They look the same so I hooked up the 20 inch to the 24 and viceversa. I'm an idiot :-)

My apple mac's screen is black, when i try to turn it back on then off again it flashs with a white screen then goes back to black. It's as if it thinks when the screen is open it is closed and when it's closed it's open, can anyone help me!!!

When i open my laptop the screen just stays black, i have tried turning it on an back on and it will turn on to the loading white screen and then turn back to black. i have tried calling apple but there tech support is closed on a sunday here in australia. If anyone knows anything i can do please let me know!!!

Try Resetting your Mac's PRAM and NVRAM
If that doesn't help, try Resetting the System Management Controller

Apple cinema 22" connected to a 1st gen mini shuts on and off

I have a 22" apple cinema with a clear enclosure (older models) that is connected to a 1st generation mac mini through an Apple DVI to ADC Display Adapter. Everything has been working like a charm, despite the flickering problem which was solved, for a bout 2 years. But this summer, the display kept going off and on by utself on its own for a few hours and then comes back on. It really feels as if the power just went off. A week ago, the display went off for what its seems forever.
I'm not sure what should I check, the mini, the adapter or the screen! Any ideas?
Thanks a lot.

My 23 inch HD cinema display is doing the same thing. It is over 4 years old and it all started with problems with the USB connections in the back about a month ago. They work most of the time, but once in a while they will just stop working for my keyboard or mouse. Now, my display is just losing power randomly. It will turn off and then back on, then again and again for a minute or two, then it will come back on without any more problems. Fortunately, the display itself is still phenomenal; colors are good, brightness is good. It seems to be just the USB's and the turning off and on randomly. Does anyone here know what it takes to correct this problem.

Hello everyone, hoping for some help with my new Apple Cinema Display 20"

Hi everyone, I bought an Apple Cinema Display 20 inch LCD monitor, just about 3 weeks ago. I have two issues I am hoping to get some help with.
1) I am using the screen on a PC with Windows XP, and I was very disappointed at the lack of PC support. I have no on screen display (OSD), so I can't see what percentage I have my brightness set to, and I can't alter the colour or contrast of the display, etc. Luckily it defaulted to very good settings, but I would really like to be able to use the (fan made?) program called "WinACD". If I would be best asking somewhere else, please direct me there. If not, my problem is that I installed it added the "Controls" tab, but it just says, Virtual Control Panel "None Present". I have tried googling for an answer, and I have seen many suggestions, but none of them worked. I installed the WinACD driver without my USB lead plugged in, and someone said that was important. So I have tried uninstalling, rebooting, then reinstalling it again with the USB plugged in, and a device plugged in to my monitor to be sure. It didn't seem to help. I have actually done this process a few times, just to be sure. So I would really like to get that working if possible.
2) I am disappointed at the uniformity of the colour on the display. I have seen other people mention this (again, after a google search), and that someone seemed to think it is just an issue we have to deal with, with this generation of LCD monitors. Before I bought this screen, I had an NEC (20wgx2), and it had a very similar issue. Most of the time, you cannot see any problem at all, but if you display an entire screen with a dark (none prime) colour, like a dark blue green colour, you can see areas where it is slightly darker than others. It was more defined on the NEC screen, and that is why I returned it. I now bought this Apple Cinema Display, because it was the only good alternative to the NEC. (It has an 8bit S-IPS / AS-IPS panel, which was important to me). But the problem exists in this screen too. It isn't as bad thankfully, but it still exists... I have actually tried a third monitor just to be sure, and the problem existed very slightly in that one, so I think I am probably quite sensitive in that I can detect it.
It is most noticable to me, because I do everything on this PC. I work, I watch films, and I play games. 99% of the time, I cannot see this problem. But in some games (especially one)... the problem is quite noticeable. When you pan the view around, my eyes are drawn to the slight areas on my screen which are darker, and it ruins my enjoyment. To confirm it wasn't just the game, like I said, I can use a program to make the entire screen display one solid colour, and if you pick the right type of colour (anything that isn't a bright primary colour), I can see the problem - albeit fairly faintly.
I am pretty positive that it is not my graphics card or any other component of my PC, by the way, because everything is brand new and working perfectly, and the graphics card specifically, I have upgraded and yet the problem remains - even on the new card. Also, the areas that are darker, are different on this screen than on the other screens I have used.
So basically, I would like to register my disappointment at the lack of perfect uniformity on a screen which cost me £400 (over double what most 20 inch LCD screens cost), and I would like to know if anybody could possibly suggest a way to fix it?
It is upsetting, becuase although this problem exists on other screens too, this is, as far as I know, the most expensive 20" LCD monitor available today, and uses the best technology available too.
p.s. If anyone would like to use the program that lets you set your entire PC screen a specific colour, it is called "Dead Pixel Buddy", and it is a free piece of software, made by somebody to check for dead pixels. But I found it useful for other things too, including looking at how uniform the colour of the screen is. That's not to say I was specifically looking for this problem by the way... the problem cought my eye.
Thanks in advance!

I've been talking about this on another forum too, and I made some pictures in photoshop to describe the problem. Here is what I posted on the other forum:
Yes, "brightness uniformity" definitely seems to be the best description of my issue.
Basically it just seems like there are very faint lines down the screen, that are slightly darker than the other areas on the screen. They aren't defined lines, and they aren't in a pattern. It's just slight areas that are darker, and the areas seem like narrow bands/lines. Usually you can't see it, but in some cases, it is quite noticeable. It is mainly when I'm playing a game. The slightly darker areas are not visible, and then when the image moves (because I am turning in a car, or turning a plane, or turning in a shooter etc.) the image moves, but these slightly darker areas stay still, and that makes them really stand out.
As for how it looks, I tried to make an example in photoshop:
Original Image:
http://img340.imageshack.us/img340/3045/td1ja9.jpg
Then imagine turning the car around a bend, and then it looks like this:
http://img266.imageshack.us/img266/959/td2hq7.jpg
It's those lines in the clouds. If you can tab between the two images, you can see the difference easily. Imagine seeing those lines appear, every single time you move in a game. (I haven't tested this in movies yet, but I am assuming it's the same).
It isn't very clear on a static image. But when the image moves, the darker areas stay in the same place and it draws your eyes towards them. It isn't terrible, but it is annoying, especially consider how much this screen cost.

How do i fix my iod touch... screen stays black

how do i fix my iod touch..... the screen stays black with the apple logo then cuts off again after like 5 minutes..... someone please help me ?

Please tell me it's not jailbroken. If it is, all bets are off. It is not...
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.
