22' Cinema (ADC) Dead?????

I have a 22' Cinema display with the ADC port. It worked fine and then I disconnected it. I attached my 20 inch ADC and used it for a while. It worked fine. The problem is now when I attempt to use the 22" it won't come on. When connected to the computer the light on the computer will not come on, but the computer is running. The light on the monitor won't come on either. If you were to just look at them, they both look dead but I hear the fans spinning and startup chime. When I switch back to the 20-it works fine so I can rule out a video card issue. Please help.

The connection wasn't properly made. Reseated the cable and it came right back.

  • 23" Cinema totally dead - how to diagnose?

    I unplugged this while moving my computer around. Plugged it back in and totally dead. Light on monitor does not light up when plugged in.
    I'm hoping the power adapter is simply dead. Is there any easy way to see if the power brick is dead? Can the Apple Store do that for me?
    And if it is, in fact, dead, should I buy the same one or one with higher power output?
    Finally, if the power brick is dead, am I potentially better off buying a brand spanking new Samsung 23" LCD monitor for $200 vs. $130 for a power adapter on a 5 year old monitor?
    Thanks in advance.

    Rainbird,
    I went to System Pref > Display and don't see "options".
    I did hook up a Dell monitor to the computer and it is fine.
    I just connected the Cinema to the 2nd monitor. In Sys Pref > Display, it shows the Dell. If I hit the "Detect Displays" button, nothing happens, but if I then select "Gather Windows," I get a window for Cinema HD.
    I have not found a place to check a "power on or off" setting.

  • How can I know if a Cinema Display 22 inch ADC is dead ?

    Hi,
    I bought a 22 inch ADC Cinema Display for my PowerMac G4/400 (Gigabit Ethernet). I upgraded the PowerMac with an ATI Radeon 7500 graphic card and a Sonnet 1Ghz processor. I'm running 10.4.9 and have the latest ATI driver for the card.
    When I plugged the ADC cable, the computer started but the display didn't light up. All lights are off and the USB ports are not powered. If I unplug he PowerMac, plug the display and plug the PowerMac back, I can't start it using the power button (on the display neither).
    I checked and rechecked my PowerMac and Cinema display specs and requirements and everything should be compatible. Is my Cinema Display dead ? How can I know for sure ? Are there any drivers I must install ?

    I'm having a similar problem, only it's recurring on several Cinema Display monitors on different machines.
    One thing we have been able to figure out is that the problem appears to be the power brick. By repeatedly unplugging and wiggling the power cord at the brick, the monitor will eventually come back on... until you restart it.
    This is VERY frustrating for such expensive monitors (not to mention being Apple products). I suspect the problem lies with faulty power bricks, and I'll be following up with Applecare to see what they have to say about it.

  • Can you help advise re video card upgrade for my G4 MDD?

    Hello all. Just upgraded to Tiger from 10.2.8 a couple weeks ago. Should have done it long ago... like having a new computer! I want to get more out of the OS for mostly graphic apps like PS-CS2, Painter, Freehand, Fontographer, etc. Right now I have 1.5 GB of RAM & will probably max it out pretty soon.
    No video or games (at least for near term). Have been doing homework by lurking here, studying mfr. sites & reading things like John Siracusa's great article (book) on arstechnica.com: "Mac OSX 10.4 Tiger". I spent a lot of last night digesting that. So I think I know what I want to do, but would appreciate opinions.
    1. I'd like to get a graphics card that will get my G4 to Core Image-enabled. According to this -- http://www.apple.com/macosx/features/coreimage/ -- and other advice I've run across in these forums, I should probably get a Radeon 9800 (or 9600) Pro Mac Edition. The downside w this is just that they're currently not to be found at any dealers I've called or googled because of the AMD merger/backorder situation. Same goes for the 9600. Bummer. In the meantime I'm wondering if one of Nvidia models listed in the Apple page might work in my machine. Probably not... but does anyone know different? Here are the models listed:
    nVidia GeForce FX Go 5200
    nVidia GeForce FX 5200 Ultra
    nVidia GeForce 6800 Ultra DDL
    6800 GT DDL
    I think I've seen most of these configured for AGP 4x, as I would need. Just don't know if any would fit into my G4... or if it would support the power requirements, heat levels, and so on that these things apparently generate.
    2. I have another requirement besides just running Tiger happily. I have hundreds of fairly big image files that all still need a lot of work, for a book project I've been commissioned to do. Average file size around 200MB. And more than half of them are in a "Legacy" proprietary format used by an out of print app called Live Picture. So even just to convert all of them from that IVUE / FITS format scheme I still need either classic or 9.2 for a while. I can still do some things in L.P. better than in Photoshop.
    It's a pretty interesting piece of software. The IVUE file is the base bitmap image. All corrections are in Vector layers on top. When done, the layers you want to apply are turned on and the final (or workaround buildout) is rendered as a TIFF, PS or stn file. (It also has a great prepress filtering engine to optimize cmyk for specific outputs). This app is VERY monitor drawing intensive - especially for layers with textures or selective color mods. When I was an early adopter in the program years ago, the developers constantly told us to do things like use as small a window as possible; turn off antialiasing unless really needed; build out intermediate IVUE's before collecting too many complex layers, and things like that. It has it's own VM system, and it does not like another Virtual Mem. running. Of course in Classic you can't turn off the OSX VM!
    Development on this app stopped the arrival of OSX, and I think even before OS9! It was crash-prone back then, and of course is even more fussy in Classic. I can boot in OS9, but for some reason prefer the "security" of protected mode, since these new-fangled machines no longer have that civilized reset button.
    So if I understand things properly, I want a graphics engine that will take the load off RAM for Quartz Extreme tasks. I've come to think that maxing RAM AND VRAM utilization will let me do more before the crash. Am I right?
    Not necessarily the same needs as for Photoshop in Tiger; but for me right now this is my critical/important working environment, as this is a big paid project (it will be a vintage watch coffee table book - which draws from a couple of the world's notable private collections). It shouldn't be long before I'll be getting a MacPro anyway. Am sort of holding out for the sophomore edition, and Leopard.
    What would you guys do? Thanks in advance for your consideration. I will greatly value your input.
    Best regards,
    Mike
    G4 MDD 867, G4 Q'slvr 733   Mac OS X (10.4.8)   also iBook G3 900 10.4.8 (G4 733 still running 10.2.8)

    Thanks very much for the info. Kind of what I thought.
    Re their price gouging - Ouch! A 66% markup from retail, and they're refurbished. I think I can wait a month or so... of course if those cards were dc'd, I might consider it. But I talked to a guy at ATI, and he didn't give any such indication.
    I did find a GeForce4 Ti4600 (NOS) for a pretty reasonable figure at another site, but that's an older, slower card. I'm impatient, so I'm tempted, but I think I'd be kicking myself if I didn't wait for the better solution.
    Are you saying that I won't really do any better in Classic with the ATI, compared to my stock GeForce4 32MB? Forgot to mention I'm using a 22" Cinema (ADC), if that makes any difference. And I'll be running Classic probably on top of Jaguar (I installed Tiger on a fresh new second internal drive). I thought I'd skip mixing Classic with Tiger altogether, but when I booted up the first time, there it was in Sys. Pref's. I guess it saw OS9 on the other drive during install. That's sort of funny.
    I guess my question is mostly answered. Will put up the flag shortly.
    Thanks again.

  • Nov 2003 PowerMac G5 gets its a second wind

    Man I can't believe my PowerMac Dual 2.0 is still alive an kicking. I've mainly replaced most duties with a faster MBP. What gave my PM its second wind? I installed an Intel X25-E 32GB SSD as the primary boot. I put the old 1.5TB Seagate on the upper slot and put the 32GB SSD in the lower. I figured I'll just install Leopard just for yucks and see how it works. Man was I surprised... Previously the main purpose of the PM was a media storage machine, music, photos, movies, stuff I don't want to clog the MBP with.
    I'm going to keep her for a little while longer and use it as an iLife machine. I have let the other apps go the the PPC grave yard (but still installed on the 1.5TB boot drive). I kept our home directories by using vifs to add the 1.5TB User partition mounted as /Users on boot and made sure to keep all uid the same with the OS on the SSD. Backups with TimeMachine to APE with USB 2TB WD Green Drive.
    Here's what she's got
    PowerMac 2.0GHz DP
    8GB RAM
    X850XT AGP 256MB (DVI and ADC)
    22" Apple Cinema ADC 1680x1050
    24" Apple Cinema DVI 1920-1200
    32GB Intel X25-E SSD
    1.5TB Seagate 7200 HDD
    Sorry Apple that 27" i7 purchase is going to wait a little while longer.

    Great to hear, thanks for the report.

  • Cinema Display to be used with DVI to ADC Adapter

    Hello everyone,
    I have a 22-inch Apple Cinema Display (clear enclosure) connected to my Mac mini (Mid 2011) through Apple DVI to ADC Adapter.
    So far, this configuration has allowed me to get beautiful OS X desktop displayed on my old Cinema Display, though it wasn't perfect.
    Pressing the display's power button does not turn off the display nor put my Mac to sleep. Instead, holding the button just makes the power LED brighter than usual.
    Two USB ports on the back of the display doesn't seem to work. It does charge my iPod, but any device connected to those ports (including iPod) won't be recognized on my Mac.
    Can anybody see what's going on here and help me troubleshoot the issue?
    Thanks.

    Pressing the display's power button does not turn off the display nor put my Mac to sleep. Instead, holding the button just makes the power LED brighter than usual.
    That's normal with the DVI to ADC adapter.  ADC (Apple Display Connector) has pins for power control but there are no such pins in DVI so the display's power button has no way to control the computer.  I don't know why the power light brightens when pushed, but mine does it too.
    Two USB ports on the back of the display doesn't seem to work. It does charge my iPod, but any device connected to those ports (including iPod) won't be recognized on my Mac.
    Is the adapter's USB cable plugged into the computer?  The displays ports are USB 1.1.  Some devices, such as iPhones, require USB 2.0.
    Failure of the USB circuitry is common with those displays.  My 22" ADC display started having USB problems years ago.  It started with intermittent USB port problems, then it started interfering with computer sleep.  Since I now use the display with a DVI to ADC adapter I don't connect the adapter's USB cable (and don't use the display's USB ports), so don't have any computer sleep problems.

  • Mac Mini - DVI to ADC Adapter - Cinema HD 23" ADC anybody?

    I would like to buy a Mac Mini, but I'm not sure if it will handle an old Cinema HD 23" ADC through a DVI to ADC adapter. Anybody has this configuration? Which is the maximum resolution possible?

    Hi
    unfortunately I think the Apple store have sold you the wrong item.
    I'm almost certain the DVI to ADC adapter only works with ADC based flat panel displays. DVI ports can output digital or analogue signals (or a combination of the two). The adapter seems to provide digital, which is why it works with the LCD displays, but not analogue, which is why it doesn't work with the CRT displays.
    Confusingly Apple did a 17" Studio display both as a CRT and LCD.
    Dr. Bott do a similar adapter but they explicitly state it's not compatible with the 17" CRT.
    Unfortunately I'm not sure there's a solution, as the display has an ADC connector yet I'm not aware of any adapters available that will work.

  • Mini with 22" ADC Cinema Display w/ADC-DVI

    Greetings...
    I've been playing with my new 1.4Ghz mini and the display I happen to have free right now is an original 22" Cinema Display. I have the ADC to DVI adapter for this display and it's rock solid on my old G4 Sawtooth. Anyway on the mini it works very nicely exept for one problem. I get a flicker that seems to tie to system activity. May be voltage variations effecting the internal video DVI drivers. OK my question it. 1) Has anyone else out there tried this combination? (Apple's monitor compatibility chart says it's supported so I know somone at Apple tried it). 2) Do you have any image stability issues like flickering. I'm asking this because I'm now wondering if maybe my little guy is a bit faulty in the video department. I'll try my new 20" display tomorrow to see if it has the same problem.
    Anyway this is an amazing little box. BTW mine currently has the minimum RAM but that will change as soon as I put this video issue to bed. Hope to use it in my studio because it's so quiet... Very nice in the sound department.
    Enjoy,

    Good news...
    Well I managed to locate a rev B version of the DVI-ADC adapter. First good news is the price is now down to $99 from the original $150. Second good news is that the /B version seems to work. No more flicker!!
    Hey Michael L... Thanks for the suggestion it worked!!
    So while this isn't the cheapest solution, it does seem to work so far and considering the cost of a new 22 or 23" monitor vs. using my excellent 22" ADC Cinema Display I'm feeling OK about it.
    So John you might want to give a rev. /B version of the adapter a try. BTW the actual adapter is absolutely identical to the REV /A version on the outside the only difference it the serial number is in a different range. If you buy an open box make sure the serial number matches on the box that shows the /B revision matches the actual unit.
    Happy Hunting... They are not easy to find. Yeah I know this $600 Mac is starting to rack up the bucks but hey considering it has better performance than my original G4 Sawtooth that I paid like 5X as much for I can't complain too loud...
    This will hold until Apple can produce a new truly drool worthy high end machine. The bar just went up with the introduction of the mini. The new once has got to be small, it's got to be silent and it goes with out saying it's got to be so fast it will make you cry. Until then I'll use what I have right now...
    Next I need to track down a good 1GB stick of ram for the Mini...
    Enjoy,

  • Old Cinema Display 22" won't work with DVI-ADC adapter & Mac Pro

    So, I want to use my old 22" ADC Cinema Display with my new Mac Pro with the Radeon x1900 card.
    And I was told to buy the DVI to ADC adapter, which I did.
    But it doesn't work! The adapter powers up my monitor, and it shows up in the Display settings of system prefs, but the monitor remains DARK.
    Anyone hear of this happening? I spent an hour with Apple Care phone support. They have no idea what to do.
    Is the 22" (model #M8149) just not compatible with this adapter? I'd hate to have to buy a whole new monitor!

    Yes, I tried re-setting the PRAM as well. Didn't work.
    I've gone into the Monitor display settings and clicked "Detect Displays"...I've changed the Hz on the VGA monitor that I have plugged in simultaneously (a Gateway FPD1510). Not working.
    As I mentioned, the computer does detect the monitor...it shows up in the Display Arrangement window and I can change its resolution, etc.
    And the power light is on.
    It's just that the screen in black.
    Is this monitor just incompatible with this adapter?
    Sounds like someone else is having this issue too, right?

  • How do I connect a new Thunderbolt MBP to and old 23" HD Cinema Display ADC port

    Can I do it and if so how? I realise theres a potential under powering issue?

    Hello Sigh
    I am sure there is no way to get your ADC connector display to function with your new Mac Book Pro.
    I tried everying I could and gave up and purchased a 24" Apple refurbbished Cinema Display for $599 + tax on 4/27/2011. The Apple part number is FBXXXXL/A, Model A1287.
    Gave my  year 2002 ADC 22" display to a friend.

    Re: How do I connect a new Thunderbolt MBP to and old 23" HD Cinema Display ADC port Jul 8, 2011 4:58 PM (in response to Russy47)
    Got my new MBP 2011 today. Hooked it up to my 23" Apple Cinema Display fine, using the Apple DVI to ADC converter > Mini Display port adaptors. I could then mirror display, but only at 1440 x 900 resolution.
    My dream is to have it like my old laptop--I mostly leave it shut, and main display is on the Cinema Display. So far, if I close the laptop lid on my new MBP, display shuts off. Also, can't get it to bump up the resolution to 1920.
    Sigh.

  • Dual Apple Cinema Studio Displays where one uses DVI-to-ADC adapter

    I have an Apple Power Mac G4 MDD dual 1.25 GHz desktop with 2GB RAM running OSX Tiger 10.4.
    It is supporting two Apple Cinema Studio LCD flat panel 17" displays simultaneously.
    Currently, it has three internal hard drives and one SuperDrive.
    I use this computer exclusively for my home recording studio for music production.
    My main computer applications are therefore, Pro Tools LE 7.4, Steinberg Cubase, and Reason 3.0.
    Also, I have the full Microsoft Office Suite, but rarely use Word, Excel, PowerPoint and Access.
    To drive the dual displays, I am using a ATI Radeon 9000 Pro which has one ADC port and one DVI port. Therefore, I am using a DVI-ator adapter to connect one of my ADC displays to the DVI port.
    Yesterday, while recording, one of the two displays developed a broad vertical band (approx 4" of black with thin red, green and blue vertical lines). The other display was fine, however.
    I decided to shut down my PowerMac G4 and disconnect the DVI-adapted display and re-boot with only the display that was connected to the ADC port. The Power Mac G4 booted up fine and ran only its display on this particular monitor.
    However, within 5 minutes, the screen re-developed the broad black vertical band with thin red, green and blue lines running up-and-down as before. Therefore, I shut it down and re-booted again. This time, it never booted back up. Rather, its progress indicator (clock picture moving in clockwise diagram kept on spinning around & around, but never booted-up.
    What does this symptom indicate?
    How can I boot-up from the SuperDrive?
    Is there some special combination of hot keys to get to its setup mode (like in Windows)?
    From these symptoms, is my PowerMac G4 MDD fixable?

    Hi-
    Welcome to Discussions!
    It could be that your graphics card has bit the dust.
    To boot to the OS install disc from the optical drive, hold the C key when powering up. This should bring you to the installer. In the window after selection of your desired language, from the menu bar, you canselect Utilities/Disk Utility. From there, run Repair Disk on the hard drive to insure the integrity of the hard drive.
    My computer won't turn on
    Now, if you are able to boot, but no video is displayed, then your graphics card is probably dust.
    My computer displays no video
    If you have a copy of the Apple Hardware Test, it would be good to run that, to verify the hardware.
    If you don't have the AHT, you can download it, and burn it to CD, and run from that:

  • Is it possible to connect an old cinema display (ADC) to an Imac (2012)?

    Hello,
    I want to add a second screen to my Imac and I found a Cinema Display (ADC). I went to see the screen and i connect it to my Macbook to test if it works. The guy who sold the screen had an ADC to DVI adapter and I bought an DVI to thunderbolt connector. It didn't work. He also tried to connect it to his Imac and still the screen didn't work. Is it even possible to connect the screen to an Imac?

    Is it the Apple version of the DVI to ADC adapter?  The signals from a Mini DisplayPort (or Thunderbolt) to DVI adapter may be weaker than normal DVI signals.  The Apple DVI to ADC adapter amplifies the DVI signals, so can work with signals that are too weak for non-Apple adapters.
    An ACTIVE Mini DisplayPort to DVI adapter may produce stronger DVI signals.
