Power Button on 23" Cinema Display Malfunction

Not sure what's causing this but recently (on occaision) when I hit the power button (which is set to "turns the display on and off") and power off the display it comes back on by itself after a few moments with the "Device Removal" error message.
Any thoughts here?? I searched help and this forum with no results so I must be doing something really stupid. Hopefully you can help me out so I don't have to bug tech support...
Thanks, J (yank)

I don't think that's true. I have everything plugged in through the back of it (cd/dvd drive, external harddrives, flash card reader w/ flash card, ipod, you name it.) However I can turn off the display using the power button right now without any error message or problem and I've been able to do so since I bought it over a year ago.
The problem is erratic, mainly coming up at night for some reason. I even tried ejecting all removable drives etc. when this was happening and that didn't help. The only thing to do now when this problem comes up seems to be disconnecting it from the macbookpro...
Any other ideas?

Power button on Apple Cinema Display 23"

I just got myself a used Apple Cinema Display and I have a quick question regarding the behavior of the power button. In the display options I selected "display power button : puts the computer to sleep or wakes it" but when I press the power button I get a popup saying "are you sure you want to shut down your computer".
The display is connected to a MacBook, running Snow Leopard. Is this a known issue I'm missing a setting somewhere?
Thanks!

Hi,
Don't worry, it's normal. Since Panther, It give you more choice. Personally, I prefer that.

Does anybody knows where can i buy a replacement AC power cable for my cinema display 27"?

It may not be the same molded plug but I would think any normal 3-prong computer power cable should work.
How about this one?

I've always had the theory that if you put two computer power cords in a drawer they will breed and you'll end up with a lot more! My parts drawer is always full of them. They like to knot up by themselves as well! Maybe that's how they breed.

Disable power and brightness buttons on Apple Cinema Displays in a lab?

We have a combination of new-model (DVI/silver) 20" Apple Cinema Displays as well as old-model (ADC/plastic) 20" Apple Cinema Displays in our computer labs. All of our computers are running Mac OS X 10.4.10.
I would like to disable the power and brightness buttons on these displays. I know I can do this manually by logging into each computer as an administrator, selecting System Preferences > Displays > Options, and checking the appropriate boxes, but obviously I'd like a leaner, meaner solution.
By the way, the option did not propogate via imaging, so it makes me think this is not a preference that's written to a .plist file somewhere. (I looked and looked and couldn't find a key in any preference file where these settings are stored...)
Does anyone know of a Unix terminal command or an Applescript command that I could send to all of my lab computers via Apple Remote Desktop to accomplish this?

We don't own these displays anymore. I ended up setting each workstation individually.

Power on a 23inch Cinema Display

Hi, My display was working fine this morning. When I went to turn it on later, the power light wouldn't come on when I pressed the power button. I took the monitor to apple this evening and the monitor worked fine. When I got home it went back to no power light. I made my 2nd monitor the main monitor and it still register's the cinema display as working, but I can't get the power light to turn on. Does anyone know what this is about. I don't understand how the power doesn't turn on, but the computer is still seeing the display? And any tips on getting the monitor to always power on when the computer starts up? Maybe that will fix this.

I have 2 23" HD displays - only 1 is detected, but its stranger than that!
My Video Card:
Chipset Model: GeForce 6800 GT
Type: Display
Bus: AGP
Slot: SLOT-1
VRAM (Total): 256 MB
Vendor: nVIDIA (0x10de)
Device ID: 0x0045
Revision ID: 0x00a1
ROM Revision: 2120
Displays:
my problem is that the second monitor is never detected. after some fiddling around, it looks like the DVI-D is probed each time a cable is disconnected, and the funny thing is, if i disconnect my working 23" from primary and insert my new 23" display to it, it works for about 5 seconds, until the video card seems to redetect the monitor; which actually this monitor isnt detected and the display goes blank...
even wierder:
i have a PC and i can boot windows up with my working 23". after the OS is booted i can unplug the good display and plug in the "non-detected" 23" and it works, at least until the monitor is probed again...
most unusual indeed.. apple doesnt know what to do.. its not the brick. im lucky to have 2 monitors of exactly the same specification and swapped the power supplies around.
not sure even where to start.. im sure apple would scratch thier heads.. funny how this happened AFTER the warranty ran out

Where do I find the power adapter for my Cinema Display?

I have recently aquired an older style of an Apple Cinema display. It didn't come with a power adapter, just the DVI cable coming out the back. I have done some research and understand that power and usb and video signal come through this one cable, but I have also come to know there is supposed to be a converter power box type thing between the display and the monitor. I can find boxes similar to the one I believe I need on Ebay and other sites, but not the exact one. They vary in style somewhat. Wondering if someone could steer me in the direction of where to get one and help me understand more of what I need and how it all works? The model/serial number on the monitor is CY3041XSLFA, it's a 23" Cinema HD Display, made in 2002. - Thanks -

If the display uses the Apple Display Connector (ADC)
<http://upload.wikimedia.org/wikipedia/commons/thumb/0/09/AppleDisplayConnector.j pg/800px-AppleDisplayConnector.jpg>
you will need a DVI to ADC adapter.

Can't find option to unlock brightness button lock on Cinema Displays

Greetings
Mac OS X 10.5.4
Mac Pro running two Cinema Displays, a 20" and a 30".
The 20" brightness buttons work.
The 30" brightness buttons are locked out.
Go to System Prefs>Displays> and I don't see anywhere to unlock the brightness buttons.
Sorry if stupid question -
where is the unlock?
Thanks

OK, called Apple and solved problem:
In order to have control over the monitor, the USB cable must be connected!
Learn something new everyday!
I was not using the USB slots on the back of the monitors, so I has never connected the USB cables on the monitor snake to the computer.

If plugged into the power supply, should the Cinema Display A1081 standby light come on without being plugged into a mac

I was given an old Cinema Display A1081 a few years ago. I am trying to test it and want to know if plugged into the power supply, should the standby light come on without being plugged into a mac? I don't want to buy a DVI to mini display adapter if it isn't working. One thing I did do was plug Monitor power in and then the USB plulg into my PC laptop and my iPhone charger USB plug into the back of the monitor. I am able to charge my iPhone this way so I know that the power supply is working. But I can't tell if the monitor itself is workign as no ligths are on. (PS: I am purchasing my first Mac so I am a complete newb but very proficient with PCs) Thanks so much for your help.

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

There is one 7500 that needs an ADC to DVI adapter, but, for the money, the 9800 is a much better card and will make everything perform better.

Single power brick for multiple Cinema displays?

I've got a client with 2 30" displays and 2 23" displays (yea, and he's wanting to add more). The big issue I'm running into is that I don't want to have 6 power bricks under his desk, due to electrical draw for the conversion to DC power. Is there anything out there which would power multiple displays?

There's no reason that one big brick would use any less power than six small bricks running the same displays.

Cinema Display Power Button Not Functional

The power button on my cinema display does nothing when pressed. The other button on the display (display preferences button) does work as expected. I have confirmed that the 'Disable power button' is not selected in the display settings panel.
The button glows brighter when I press it, but nothing else happens.
I would like to be able to start up and shut down my computer with this button since my bluetooth keyboard cannot do it, and I keep my laptop shut when it is connected to the external display.
I was just given this display, so I do not know if has ever worked.
Any ideas?

Hi Ron,
Possibly a daft question but do have either of the Cinema Display's USB or firewire cables plugged into your G4 as well as the DVI connection? This may sound obvious but I couldn't get the buttons on my 20" ACD to work until I plugged the USB connection into my Macbook.

Cinema Display 30" and MBP - No Picture

I have a 2.16 Core Duo Macbook Pro 17". Today I purchased a 30" Cinema Display at the Apple store.
Because of issues I had heard about I had the Apple employees help me open the box and plug in the monitor to a Macbook Pro on the floor to check for dead and hot pixels and other screen problems. None found. I was so psyched!
I get it home and set it up. I run the DVI cable over to my Macbook Pro and nothing... The MBP screen goes blue and then refreshes when the monitor is attached or detached like it detects it, but under system profiler it never registers an additional display (and I did refresh the info). The soft power button on the Cinema Display triggers my computer to give me the shut down/sleep dialog so something is registering.
Basically everything works on the display but the picture. I just get a black screen. I hooked up my wife's G4 1.67 and it drives the screen just fine with a picture.
Any thoughts?

I have owned a MacBook Pro (15" / 2.16GHz / 2GB) and 30" Cinema HD Display since September 2006.
The display's DVI, USB, and FireWire cables are all connected to the MacBook Pro. A keyboard (with mouse) and iPod dock are connected to the display's USB ports, and two LaCie D2 drives are connected to the display's FireWire ports.
The display has remained blank at start-up on two occasions, both since upgrading to Mac OS X 10.5, though that may be coincidental. In any event, unplugging the display's USB cable from the MacBook Pro had the effect of waking the display; plugging the display's USB cable back into the MacBook Pro put the display to sleep.
Try disconnecting the USB and FireWire cables from the MacBook Pro and unplugging any peripherals attached to the display. I found that everything worked fine when reconnected.
