Strange Problem on my 17" Studio Display

Ok, just to get the specs out of the way - 2 17" Apple Studio Displays, both connected with ADC to DVI adapters to a Dual Core 2.3 PowerMac G5, running OSX 10.4.7, 2.5 GB RAM.
Saturday night we had a VERY bad storm - my wife and I were out when it hit, and my computer was on. I wasn't too worried as both displays and the tower are running off of a UPS/Surge Protector.
By the time we made it home, the battery backup had run out of juice and the system was shut down. We were out of power for about 12 hours. When the power came back up on Sunday - I booted up my mac.
As the initial Apple logo bootup screen popped up - I knew something was wrong. The background was a dark gray and the apple logo light gray - the opposite of what it is normally.
After the computer finished booting I'm left staring at my 2 displays in amazement. The display on the left looked as if the display had been inverted in the Universal Access Pane, and the right display was perfectly normal.
I can go into the Preference Pane, or use the shortcut CmdOption+Cntrl8, and all this does is flip which display looks normal and which one is inversed. I can't seem to find a way to get them both to display the same.
I've repaired permissions, I've rebooted, I've reset the PRAM, I've trashed preferences, I've scoured the Apple Discussion boards, I've spent hours on Google, I've run hardware tests on my G5, swapped the display outputs on the card to see if it was the video card - but the same display always shows inverted. I've also connected the suspect display to my Powerbook and it does the same thing, which leads me to be pretty certain its an issue with the display - not the CPU. I have no idea what to even try next.
Does ANYONE have any ideas for me to check out? I'm open to anything at this point. I've found a place that sells replacement parts, but have no clue what part I would even go about replacing.

1. Shut down the computer. If you cannot do this because the mouse or keyboard are unresponsive, then hold the power button for ten seconds.
2. Verify that the system is shut down by pressing CAPS LOCK. It should not light.
3. Power-up the system and let it start.
4. If the + key continues to repeat, it is probably a bad keyboard.

Help! Strange Problem with 23" Apple Cinema Display and Wireless Internet

For some reason, Safari runs much much slower on my housemates new 23" Apple Cinema Display than just on his new Macbook. He is running Tiger. We use Airport Extreme for house-wide wireless, and he has an Airport Express to connect to his printer. Here is what he wrote:
"Last night, I was watching videos on ABC.com --- not a problem to watch on my laptop screen (new Macbook) - very fast. Then, after dinner, I plugged in my external screen (Apple Cinema Display), and it was so slow and wouldn't load. I unplugged the screen, and it was lighting fast again, so I watched the videos on my laptop screen. This morning, I was plugged into the external monitor and the Internet was slow to check my email. I unplugged the screen, and it's lightning fast now on my laptop screen.
Does this make any sense??? Why would my external monitor affect the Internet speed? "

I am having a similar problem as well. When I attach my 23" cinema display to my MacBook core 2 duo, my connection to the internet immediately stops working. I have tested this several times and it happens every time I connect the Cinema Display to my MacBook. When I disconnect the Cinema Display, my internet connection works perfectly again. I'm stumped as to why this happens.
I have tried several different searches on the forums, but have found no other threads besides this one. I'm I won't have to suck it up and pay the $50 for the call to AppleCare support.

Brand new mac mini and Studio Display 17" LCD- 2 adapters needed- problems?

From many forum posts here and elsewhere it seems I can in fact hook up my Studio Display 17" LCD monitor if I used the ADC-DVI adapter. But has anyone used the ADC-DVI adapter AND the DVI-mini DVI adapter that came in the box with the Mac mini?
Apple tech support told me on the phone tonight that doing so would "fry" the Studio Display.
Has anyone had any problems using this? Will running it through 2 adapters cause problems as opposed to the older minis where you could just do ADC-DVI and then into the computer?

Were you able to get your display working? I have an LG 27" at home connected to a Mid 2012 (June) MacBook Air 13" that has absolutely no issues. However, I just obtained the same Samsung monitor you have and appear to be having the same issue.
The only solution that I have found is to unplug the power from the back of the monitor or at the power supply each time my computer either wakes from sleep, screensaver, or a display that is powered off. This seems to be true via the following connections:
1. HDMI to DVI thunderbolt adapter
2. HDMI to Thunderbolt adapter
The display powers on with a slight flicker and then will immediately stop displaying the image on screen. What's especially strange here is the MacBook Air still believes the display is connected -- my login screen or active apps that are displayed on the external monitor do not move to the MacBook Air display as if it's no longer connected.
I hope someone has a solution to this issue! Thanks!

Display Problem - Video noise with 15" Powerbook and 23" Studio Display

I just bought a used 23" Studio Display to act as a second monitor for my 1.0 GHz 15" Powerbook. In my set up, the display is rather noisy -- there are consistant flickering lines of white pixels throughout the display. The lines are worst in dark areas, though they may just be showing up under contrast. The Powerbook it is connected to still looks normal.
The first strange thing is that the display works perfectly with another 1.25 GHz 15" Powerbook I have to test it on. In both cases, I have connected the monitor to the Powerbooks with a new Apple brand powered DVI to ADV Adapter.
The second strange thing is that the display seemed to act fine until I reinstalled my Wacom tablet driver so that it would work with dual displays. I've uninstalled the driver, but it the problem is still there.
The third strange thing is that the display is fine while booting up. The blue boot up screen is very crisp looking and noiseless. It only starts showing noise when the login screen shows up.
Any thoughts about what may be causing the problem or how to fix it would be appreciated.
Thanks.

Powerbook 15" G5 dual 2.0 Mac OS X (10.4.7) 23" studio display

Well I called AppleCare yesterday and, believe it or not, we actually got the USB ports acting normally - well at least I can boot up with the keyboard plugged into the back of the monitor.
They had me reset the Open Firmware and that seemed to do the trick. Of course, the night before I updated to 10.4.10 so that may have had something to do with it, too. No idea.
As for the power sensor button thing, they wanted me to plug the monitor into a different system, either at a Genius Bar or a friend or whatnot to see if it would behave in the same manner - not wanting to activate. I took it to school with me and hooked it up to one of my teacher's G5 and it behaved the same way. It took like 15 times touching the sensor to bring the system up.
So I'll be calling them back and see where they want to go with this. Maybe I'll get lucky and get a new shiny monitor - or not...

Strange Problems With Display and Permissions Since 10.5.1 update.

Since I've done the 10.5.1 update I have been having a strange problem with my desktop and dock displays. On my desktop I have these strange lines that appear any time I log in or open any application, the lines never go away and change locations on the screen once I open an application or move a window. My dock has the reflective shelf for about half of it, the rest is a dull grey. I've also had problems with verifying and repairing my permissions. I can never actually complete either permissions task. I've used some third party apps, they always fail as well. The only time I can actually repair my permissions is by booting in to single user mode and doing a fsck -f command. When I boot back in to Leopard and try to use the Disk Utility to repair, it continues to fail.
I'm not sure if the video problem I am having stems from a permissions issue or possibly a corrupt video driver. Either way, I've done a lot research and haven't found anyone with the same problems I have been having so I thought I would give these forums a shot.
I am using a PowerMac G4 Quicksilver with dual 800Mhz, 1.5gb RAM, and a GeForce4 Ti 4600 128mb video card.
Here is a screen shot of the line and dock problem.
Here is a screen shot of my "About This Mac.
If anyone could lend some light on this issue, I would greatly appreciate it.

Older Studio Display Problem

I have an older (clear base & grey/white stripe) Apple Studio Display hooked into an older 2GHz PowerPC G5 running 10.4.11. I went to turn the machine on as usual by touching the sensor on the display. The machine turns on, but nothing displays. Checked connector, still same problem. Hooked old CRT into other slot on card (GeForce FX 5200) via ADC adapter, and that works, but nothing on ASD. System Profiler recognizes the ASD, says it's on online, but no picture on screen. Any help would be appreciated.

Personally, it sounds like the back light went out. I don't think it is worth fixing. Go splurge on a 24" Apple LCD Display

17" Studio Display Problem/Question

The bottom right light/button on the display started constantly blinking and the top portion of my screen has decreased in brightness. The bottom portion looks fine. Any ideas on the problem?

Heres an update to what I have done.
I took the G4 to work and put in a PCI card from another machine. I connected it to a CRT monitor and it worked fine. All the resolutions support showed up. So it has to do something with the studio display and or the nvidia card.

Very strange failure of 17" Studio Display

I'm running a G5 with 10.4.11 and a 17" studio display. I was out of town for a while, came back night before last and started up. All peachy, no problems at all. I got a system update message, OK'ed it, then restarted when the download was complete. On restart, the screen was black. I know the machine started up and works fine; all the familiar sounds are still there, I can adjust the volume, etc. But even after multiple cold restarts, unplugging everything for half an hour and coming back, etc., no screen.
I find it hard to believe my display just died all of a sudden when it had no problems at all before. The power light in the bottom right corner still comes on, as does the other one in the bottom left (brightness? never use it), so I don't think it's a connection issue (also, the connection was fine up to the failure and nothing about it had changed). I am trying to track down someone with another monitor, but anybody have any idea what could be going on?

DVI (computer) to ADC (display) adapters are only for LCDs, not CRTs. Most do not pass trough the analog video signals needed for a CRT, and do not provide enough power. I have seen reports that the Gefen DVI to ADC adapter
<http://www.gefen.com/kvm/product.jsp?prod_id=1203> does pass the video signals, but the power supply gets VERY hot when running a CRT. You could replace the supply with a bigger one. I think you need 28V 4A.

Re: Problems with USB hub in Studio Display

Ok, so I read a couple of posts here about USB hub problems with studio displays. Well... lucky me. I just got a used 17" studio LCD from craigslist.com (a local person) only to discover a day after getting it that it abruptly tries to go to sleep on its own; or the usb hubs in the back stopped responding; and/or it would intermittently flicker on and off like it was trying to go to sleep but couldn't. The screen itself is perfectly fine and clear when its own and I can get it to stay on for awhile with no problems, but just from my impression from the thing, this problem is going to continue. Was there ever a reasonable solution for this USB issue? My computer was running fine before on a 17" CRT Studio Display. And unfortunately, I've already given that one away.
<--- Poor student, so I'm hoping I'm not SOL.

Is your USB hub a self-powered one? Meaning, does it have its own external power supply?
If it is, make sure its power supply is plugged in to a live source. Also, some self-powered hubs have a small selector switch, allowing the choice of bus or self power; if it has such a switch, be sure it is not set to "bus".

15" Studio Display Backlight Problems

Hey everyone!
I got a "new" PowerMac G4 with an Apple 15" Studio display. Both are from 2001. G4 has no problem whatsoever. But the screen keeps flashing its power LED. The pattern is short short long. I checked the Apple Manual, which said that this Display has a backlight error. The error is that i can't adjust the brightness of it. Is there a way i can make it normal? I can't really send it back to Apple anymore:/

15" Apple Studio Display problems

I have an old 15" Apple Studio Display (Blueberry) that I'm using with my MacPro. Every once and awhile it will flicker. It acts like it turns off and then on. The screen never goes black. I can still see whatever is on the screen. In fact, it gets larger for a split second.
The connection is good. No loose cables.
I am sharing the monitor with the Blue and White G3 using a Belkin Flip.
Any ideas?

Do you hear a zapping sound when it happens? It could be high voltage arcing. Blowing out dust might help.

Powerbook 15" G5 dual 2.0 Mac OS X (10.4.7) 23" studio display

It's plug and play, so that's not an issue.
The debate about running the clamshell closed is so that, if the extra desktop space is not required, there is no point "stressing" the video ram and videocard and cpu by having the other display running - all resources can turn to the external display.
As for extending the desktop, yes you can do that with Photoshop - you have the space of the PB and the new display, entirely up to you what you put where - just drag across.
Performance wise, I don't imagine that Photoshop would cause as many difficulties as say video editing might, and I've not come across anyone saying that they have had performance issues from running the extra display - you may get some extra heat as the processor is taxed though.
If in doubt, you could test at an Apple Store or reseller.
Also, you might find getting extra ram a useful upgrade.
Hope that helps, best of luck.

Short code causes a strange problem - About the list again -- please read!

Hi again people. Maybe you remember my project - has a list, that you can search thru using a text field. During the work I got stuck on a strange problem ( Again :-( ) My app has one text field, one combo box, one list and a text field once more. The code should do the following ->
*1. Load the list, no problem with that.*
*2. Show the elements of the list, that match the selected group in the combo box,no problem.*
*3. Search thru the list using the text field,no problem.*
4. When the user selects an element from the list, it should display its info in the second text field. This also works fine, but when after looking at info of one of the elements the things on numbers 2 and 3 ( look up! ) stop working. I must say that everything works fine until user selects an element from the list. I couldnt understand this kind of behavior so I am asking you to help me please.
The code is very simple:

        JPanel panel = new JPanel(null);
        Container c = this.getContentPane();
        c.add(panel);
        text_field.setBounds(10,10,170,25);
        text_field.getDocument().addDocumentListener(this);

refresh();

Now, can you please tell me whats wrong with this?
For the "data.txt" make a new text file using *notepad* and copy the following line into the document:
_1. element#1. info#0;2. element#2. info#0;3. element#3. info#1;4. element#4. info#1;5. element#5. info#1;_

Keith, thanks for making that readable. So here's the diagnosis -
In the refresh() method, calling defaultListModel.clear() results in a valueChanged(...) event in which this method calldefaultListModel.getElementAt(list.getSelectedIndex())results in the exception noted, as getSelectedIndex returns -1, the list being empty... you can't getElementAt(-1).
I haven't analyzed all the code nor checked whether is now works as desired, but this small change to valueChanged counters the exception being thrown.   public void valueChanged(ListSelectionEvent e) {
infoField.setText(""); // do this unconditionally
if (list.getSelectedIndex() != -1) {
String value = (String)defaultListModel.getElementAt(list.getSelectedIndex());
for(int i = 0; i < numFields; i++){
if(value.equals(matrix[0])){
infoField.setText(matrix[i][1]);
break;

Yea! You were right! I didnt think that calling *list_model.clear();* will result in calling *valueChanged()* ........
That was some *clear()* thinking :-) Thank you!

Problem connecting a 24" Cinema Display to an Imac 27"

My friend has an Imac 27 "with a graphics card AMD HD 6970M 1GB. She wanted to connect an external Cinema Display 24" (without thunderbolt serie). The external display has started to display black screen intermittently while making a strange noise. Before this screen, there was a aluminum Cinema Display 20 " which never had any problem. The 24" Cinema Display was just before used as external screen for a Mac Book Pro 15" (main screen, no dual screen) without problem too. Any idea? Is the card too weak for such a configuration?The iMac was purchased on October 15th on the refurb. The Os is Lion 10.7.2.

If the computer doesn't have a Mini DIsplayPort or DisplayPort, not until September; click here for more information. If you mean the MagSafe connector, leave it unplugged; it's only for laptops.

15" Apple Studio Display Shutting Off

My Apple Studio Display (LCD 15", purchased 2000) visual display is intermittently shutting off. Audio remains functional, and I can still type while the display is absent and when it comes back what I typed (ie, on a word doc) is there. The screen saver does not come on during the loss of visual display - the screen just goes black. When I move the mouse around or hit the keyboard repeatedly, the visual will come back. There are not problems with the display when it is visualized. Here's what i've tried so far:
1. All connections are secure on the ADC cable.
2. Tried restarting computer several times - no avail
3. Checked the display settings in system prefs - energy saver is @ 15min.
I'm wondering if the problem is the monitor or something with the computer. I read somewhere in discussions that PRAM batteries can be a problem (mine has never been changed and I don't know how to reset).
Any suggestions would be appreciated. I really hope to continue to use my monitor!!
