Dirt on inside of 27 " cinema display?

the display on my imac's 27" has developed what appears to be dirty splotches on the inside of the glass.

Briefly what you need to do is lift the cover glass off (e.g., using suction cups) and clean it.
You can see sime youtube videos of this:

iMac : cleaning under the glass
iFixit has a tutorial on how to install the glass which shows some of the related details:

Finally, do a google search for "dirt under imac glass" to find these and other hits on this subject.

Disconnecting Cinema Display Leaves Windows Stranded on Laptop

Dear All,
I use a 17" PowerBook with a newly purchased 20" Cinema Display in dual screen (non-mirroring mode) at work and just the laptop at home. The CInema Display is set as the primary monitor.
Using Excel in dual screen mode before leaving work on Thursday, I had a spreadsheet open on the laptop (secondary) screen. I disconnected everything and went home. Now, with only the laptop, that spreadsheet is inaccessible. It's open and, by using Expose I can see it, but when I pick it, it just slides off the screen.
Is there any way to get it back?
I'm figuring when I get to work I'll be able to get it. And I also assume that I should have probably gone through a "detect displays" sequence after disconnecting (although that's not working now). Maybe using the laptop as the primary display is the secret as well. However, it would be nice to be able to get it now.
Incidentally, I do not find Apple's dual screen setup very elegant. Having the main menu only at the top of the primary screen means a lot of mouse movement when using the secondary screen. In addition, when I use right click menus on some secondary screen programs, they appear on the primary screen.
Thanks for the help... Jim
PS - For those who saw my post on another forum about a window too large to access, it is not related to the dual screen. It is running on a different system without the dual screen although I tried using the larger dual screen to acces it (unsuccessfully).

Open the Script Editor in the /Applications/AppleScript/ folder and run the following:
tell application "Microsoft Excel"
set bounds of window 1 to {61, 95, 465, 313}
end tell
Insert the application's name in the first line inside the quote marks, press the Run button, and then resize the window. Close all open documents in Excel which you can see. This script may not work for all applications.

17" LCD Cinema Display does not work on G4 Tower with ATI 9000

Hi,
I have a G4 Tower with the original AGP ATI Radeon 9000B video card. My friend gave me this unit just recently but not the original monitor. Well after he got his new 30" Cinema Display he gave me the original 17"LCD Cinema Display. I was so happy, plugged it into the card and fired up the CPU but nothing! just blank! It is not getting any power for the USB ports or anything. My buddy says the monitor was checked before I picked it up. I yanked the Video card out and put it back in, inside the CPU was clean as was the card, put it back together and still nothing. The VGA monitor I have is connected via adapter to the other input and works fine. I tried doing display settings and the Cinema is not even detected. Is the Video card fried on the digital side?
Do I need a new one?
Here is the info on the CPU:
Machine Model: Power Mac G4 (AGP graphics)
CPU Type: PowerPC G4 (2.9)
Number Of CPUs: 1
CPU Speed: 400 MHz
L2 Cache (per CPU): 1 MB
Memory: 1.5 GB
Bus Speed: 100 MHz
Boot ROM Version: 4.2.8f1
Serial Number: XB0120xxxxx
Any help wold be appreciated.

Hi MFG,
Welcome to the discussions.
The G4 AGP Graphics model originally shipped with an ATY Rage 128 graphics card. The ATI Radeon 9000 graphics card that is installed in your G4 is not the original card.
The ATI Radeon 9000 comes with a native ADC port (which you are trying to use). This port is only fully functional if the computer is ADC enabled. Your model of G4 is, unfortunately, not ADC enabled.
You can confirm this by opening the computer and having a look at the AGP slot (where the graphics card is installed). In ADC enabled Macs, there is an extra slot at one end of the AGP slot to accomodate an "extra leg" that the ADC graphics cards (such as the ATI 9000) have. This extra leg supplies the power and USB feed. You'll probably find this extra leg with no slot for it to go into.
What this means is that you are not getting power and USB feed through the ADC port to your display.
If you want to get the 17" ADC Apple LCD display working off this card (it's definitely the LCD display and not the CRT display, please confirm), you will need to use a DVI to ADC adaptor such as this one:
http://www.drbott.com/prod/db.lasso?code=0111-DVAD
and run it off the DVI output.
You can run your VGA screen at the same time (if you want to) off the ADC output by using this adaptor:
http://www.drbott.com/prod/db.lasso?code=0117-ADCV
This will work off the ADC port because, although the ADC port is not getting USB or power feed, it's still getting the DVI feed (which is what this adaptor needs).
Cheers!

Problem with tilt of 30" Cinema Display

I have an Apple Cinema Display 30" which works just fine and I had it just slightly tilted up but I had to move it back and now it's stuck and I can't move it back to that slightly frontward tilt. I notice there is a little screw-- I just had the display fixed by Apple [the inside lights were fixed] and don't want to hassle taking it back to Apple store or sending it out....does anyone know if it would be a fairly simple thing to unscrew that and move the display or is there something there that I should be concerned about?

Being HDMI it should really only offer options that are supported by your connection and the issue of a mismatched output shouldn't occur, however since your monitor isn't really HDMI I can't be sure what will happen.
When using component the tv offers all resolutions supported by itself regardless of whether the tv supports them and of course when they don't match the tv is blank. I think it may be possible that this is what happens when HDMI is connected to DVI. I really can't be sure but I think this is worth testing for.
In component mode if you select a video mode that isn't supported the screen will go blank and if you leave it a while the tv will reset to the last output you were using.
When you change video mode it can take a few moments for the change to take effect, so don't be too impatient when cycling through the options.
Finally, just a thought, your gender changer does support DVI-D/DVI-I and not just DVI-A doesn't it.

Can I use an Apple Cinema Display as a second monitor for my iMac?

I have a new 24" intel iMac and was wondering if I could use my old 20" Apple Cinema Display (aluminum) as a dual display. What cables do I need?

Just had a good look inside my box and nothing. Maybe it's a Apple UK thing
The back of my iMac does have a Mini DVI port so I'm gonna pop down the Apple store tomorrow morning to pick one up.
Thanks for the advice, I'll let you know if I'm successful.

Taking my 20" Cinema display on the road; how do I remove the stand?

Hi everyone,
I'm planning to do alot of work on location this summer and would like to find a way to remove the stand attached to my 20" LCD Cinema Display so that I can pack them both into a smaller case. I've just removed the allen key cover on the right hand side (from the front) and was presented with a more complicated challenge inside the mount. It seemed to me to be a good time to consult the support forum before things went horribly wrong....
Are there instructions anywhere that show how to dissasemble the hinge where the display meets the stand? Without destroying either?
Can anyone recommend a lie-flat/two piece stand I can take with me on location?
Many thanks,
Andrew

Look at me; I'm clever.
Solution found at http://manuals.info.apple.com/en_US/073-0933.pdf
After removing the two screws, the stand didn't want to pull off easily and I thought it may still be attached. It turns out that the attachment point was just sticky and needed a firm pull.
Thanks internet!

VMware Fusion and Apple LED Cinema Display

I have a 2008 MBP and a 27" Apple LED Cinema Display. My OS is 10.7.2.
I am running Windows 7 with the latest updates in VMWare Fusion 4.1.1. I have several issues.
1) When I go to chose my monitor it say Apple LED Cinema Display but "Generic Non-PnP Monitor." I downloaded and installed the boot camp drivers as I understood those contained the drivers for the monitor, but that didn't seem to help. Do I need to have the Boot Camp drivers?
2) When I try to access the Boot Camp Control panel in Windows 7 in Fusion I get "An error occured while tyring to access the startup disk settings. You may not have privileges to change the startup disk." My guess is this is because the Boot Camp drivers are only needed if you actualy run Boot Camp.
3) In Windows I cannot choose the native resolution of the Apple display (2560 x 1440).
4) The resolution ia 1277 x 1234. That is weird.
5) If I minimze the Fusion window and then immediately open it, it looks fine. But if I wait for awhile and open it, the window will be black until I click inside of it.
Something is wrong, Any help in fixing this would be greatly appreciated.
Bryan

you have to separate out what is Fusion and what is Windows native.
Even doing updates to Windows sometimes should not or cannot be done properly in VM.
And there is no way to change the default boot drive - a VM doesn't have access and that is the host OS's job, not the guest's.
Install the latest AMD driver for mobility - and dont' use the "auto detect" - that is not going to work on Apple hardware.
You dont' run Boot Camp. But the Apple drivers and serives needed for hardware support, yes, they aren't running or loaded.

24" Cinema Display flickering and eventually going dark

I am having a repeat of a problem with my Apple 24" Cinema Display. The symptoms are the display will go black and come back on (flicker) and sometimes it takes a few seconds for it to come back. All USB devices connected to the Cinema Display become disconnected from my MacBook Pro when this happens.
Last time this happened it started slowly and as time passed it happened more frequently. When I brought it into the store they were able to reproduce the problem immediately. They replaced the logic board in the monitor.
I contacted support again. The display is still under warrantee. They scheduled an appointment for me to bring the display in. I am seeing the same behavior where the frequency of this problem increases as time passes.
I am concerned they will be unable to quickly reproduce the problem again and not fix it, or fix it and the problem will come back again in a few months. I am afraid that I will still be having this problem after the warrantee expires.
I've purchased many displays over the years (including Apple) and this is the first time I have ever had a problem. I think I may have had a lemon.
I originally posted in these now archived threads:
http://discussions.apple.com/thread.jspa?messageID=12175983#12175983
and
http://discussions.apple.com/message.jspa?messageID=12311032#12311032

Just a quick update. I brought the display into my local Apple store. After they reviewed the records from the previous repair and my description of the problem they believe it could be a power supply problem inside the monitor. The power supply may have caused the logic board to go bad. Replacing the logic board last time fixed the problem but the bad power supply ended up causing the problem to return.
I let them know that I was concerned that this is a reoccurring problem and my warrantee expires in July. I don't want to see this problem come back after the warrantee expires.
I'm not sure what they will do if that happens. I hope this problem gets fixed this time around.

PowerBooks and Cinema Displays

I should know the answer to this but...Can the PB be used with the Cinema display only and with the lid closed?

I thought about that but the truth is the PB actually stays cooler with the lid shut. I've been watching it closely. It's kind of like the question about whether or not your refridgerator light goes off when you shut the door. When the lid gets closed the processor goes to sleep. Clicking the mouse wakes up the Cinema display and my obvious assumption is that the PB display is off while the lid is closed. This seems to cut down on the heat build up. I also use a Targus Podium Coolpad to elevate the back end of the PB and it stays very cool.
The only glitch I've had with the lid closed is that my Airport connection also shuts off. So I use my Airport Express to convert back to hardwire and re-connect to my Ethernet port. That way I can stay connected and I also reduce heat build up by not running the Airport card inside the PB.
Having said all that I also agree using both monitors is very handy.
Thanks for the feedback.

Will a wet dropped 20 inch Cinema display work?

I have a Cube and 2 ower Mac G3s I had been eyeing a display for ages at a local junk store Hard Off in Japan 'Do not laugh ! in the past years since the Earthquake the Jaanese around Sendai have been throwing out broken things caused by the 2011 Eartquake I have picked u some rubbish and good stuff I like to take apart Macs and try to fix or mod them.
Today I came across 2 Aple Keyboards a Blue tooth Mouse and OBS 20inch Cinema display ! wow ! it had been raining hard for 3 days they were dumped at the Tohoku University QawaOochi Campus ,famous for Fibre Optics and now Gigabyte internet spead research They are famous for getting top funding so they renew Computers often and just dump the unwanted they can not sell or give them away !
I took it to work and I was on my bike ,when I got off it droped on the ground and the plastic corner cracked but I was more worried about the water inside.
I dismantled it and found water inside the clear plastic case and the case that looks Aliminium but it is lastic the screws are tough to unwind and was well closed
sorry image to large so can not insert. It is possible water seaped into the front of monitor ot not the back.
I may have broken cracked some inner circit board by dropping the water can dry as long as I give time in a warm dry place before replacing the back lastic but I dare not venture further because of foil and complex metal casing inside,there is a mesh cover and inside a mother board I am thinking when the weather hanges to put it outside in the sunshine and the air in autumn is very dry here on clear days I need to warm it and a breeze at the same time.
These things were 3,999 USD when new and now are just 100 USD on eBay if it does not work I will take apart and sell the parts.
I left the 2 Keyboards alone , once water gets in they are difficult to dry and will short.

Replace LCD in 23" Cinema Display?

I recently acquired (for $100) a 23" Cinema HD Display with a cracked LCD. The display lights up and displays so it seems to be working correctly despite the loss of the LCD. I can buy a used replacement for $250. Assuming the replacement LCD is fine, how hard is it to disassemble,repair and reassemble a Cinema Display? There are no visible screws or other ways in and I'm guessing a lot of glue in involved. I have replaced LCDs in many laptops (including titanium PowerBooks) but have yet to attempt anything on this scale before.

I'm in a similar situation where I have an out of warranty cinema display that does not work. Apple want more than the cost of a new display to replace it!
I want to get inside it to see if there are any obvious problems but cannot find any information on the web on how to do this. A number of people have suggested that the sides are either glued on or held on with clips. I think its glue myself so would use a hair dryer to help loosen before removing.
Can you let me know how you get on if you go ahead with the repair. Thanks and good luck.

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.

Apple LED Cinema Display extreme Smell

Hi, I recently bought a Cinema Display and i can't get rid of its "New electronics" smell.
Each time the Diplay is turned on, and the fan is turning this penetrant smell starts filling up my room.
Has anybody experienced this ?
I bought a new Macbook pro at the same time and that it stopped smelling after one or two days.
Its really annoying, each time i work an hour on the Mac i get a headache
By the way i sometimes experienced the well known ticking sound when I turn down the brightness of the display under 50%.
An other thing i noticed was that when i turn the display on it cracks, like something inside is expanding under the heat that is build up.
I will bring it back to the Apple dealer, see if i can get it exchanged for a new one !

Brightness is controlled via USB. Is the display's USB cable plugged into the computer?

2010 13" MBP performance with the 27" Cinema Display

Hi. I have a 2010 13" Macbook Pro bought about a year and a half ago (my first Mac and despite the problems described below, I'm a very happy camper), with RAM upgraded to 8 GB but otherwise it's pretty much a standard issue machine, certainly still a good computer. Last summer I bought the 27" Cinema Display to go with it and I just love it. From time to time, though, I'm a bit concerned about the performance of my computer with the display. I usually use a lot of apps at a time (hence the maxed out memory) and with the display, more often than not, the computer runs a bit on the slow side, the animations are not the smoothest, the "beach ball" is oft-present, or, very prominently, there's no way flash video (such as on YouTube) plays smoothly in full screen, making it unwatchable (I often "cheat" by using the universal access zoom to magnify the video, which does the job pretty well). The fan inside the laptop usually spins audibly at the maximum RPM and the CPU temperature is usually around 70°C (rarely less, but rarely much more). None of these problems happen when I'm using it without the display, on the road. I have already given up on keeping the see-thru Zagg plastic case when at home and not traveling, to keep the computer cooler in the clamshell mode and I'd be willing to buy an external cooling system (the Moshi Zefyr 2 cooler looks really worthy) but do you think the performance degradation could be heat-related at all? I know my MBP is really the entry-level model and still has the ancient C2D CPU, only 256 MB of video memory and I shouldn't expect miracles. But I just wanted to make sure I'm doing everything right and my computer is really "supposed" to perform worse with such a large display. Thank you very much for any kind of help or advice.

Thanks a lot for your reply. Isn't it weird, though, that Apple would make the display compatible with all of their notebooks without any warning about the possible performance penalty with some of the lower end models? Why aren't they offering smaller external displays? And the MBP 7,1 is no slouch too, when this particular Cinema Display originally shipped, it was the most powerful Apple laptop after the 15" and 17" MBPs.
Oh well, it still works OK though, and I'm going to stick with this setup for at least another year or so, certianly till after the rumored MBP redesign takes place and I hope the graphics on the future machines will be powerful enough to drive large displays smoothly. It's a good thing the Cinema Display is future-proof and forward compatible with the Tunderbolt port. All in all, it's a beautiful display and will remain so for a long time.
Do you think an external cooler (such as the mensioned Zefyr 2) would help in the meantime?
