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:/

http://www.ifixit.com/ may have some do-it-yourself solutions.

  • 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...

  • 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.

  • 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".

  • 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.

  • 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.

  • Studio Display: power but no video??

    I have a Studio Display monitor connected to Quicksilver G4 via the ADC cable. The monitor is getting power but there's no video. I don't have access to another ADC-equipped computer for testing. Any ideas as to where the problem might lie?

    Check to make sure your video card is firmly in place in the AGP or PCI slot. If l not firmly in place it can cause a black screen on boot. Also, is the backlight on the monitor lighting up when you start the monitor? Try holding a flashlight or other bright light up to the monitor to see if you can see anything, if you can see something then its working, but A) the backlight is turned down, or B) the backlight is dead.

  • Repairing the 17" Studio Display myself - instructions?

    I'm looking to replace the backlight inverter on my 17" Studio Display. Does anyone have some easy to follow instructions for doing this?

    Could be a bad display or bad graphics card.  Try the other port on the graphics card.  If that fixes it, then it's the card.  If not, you will need to try the display on another computer, or try a different display on your computer, to isolate the problem.

  • 17" Studio Display flickers on & off, then died

    My Apple Studio Display is about four years old now.
    Yesterday, it started flickering on and off for a while, then it completely died.
    I let it set overnight, and proceeded to make "funeral arrangements" for the beast that I had so lovingly cared for...
    I even took the Studio Display to my daughters home and connected it to hers since its the same computer.. and it started flickering again, on and off, etc...
    Late this afternoon I went to pay my respects to my Studio Display whom I had been cussing out all morning, when it "came alive"....yes....."alive"....
    And, as I write this, I feel like a much loved member of my family has risen from the dead and as if nothing had ever happened to it...nothing...nothing..
    In my insignificant opinion, this "Studio Display" is about the best looking monitor I've ever seen from Apple. But, I will not be "fooled" again...
    Now that this f%#@&'in display is working, I've done some important research as to what other monitor I'll be buying when this piece of crap really dies on me!...
    I recall that I paid $1,000 for it originally. I've checked out some highly rated monitors, and when this present miscreant passes away, I most surely will not spend a cent to have it repaired, but go to the nearest Compusa or Staples, or whatever and pick up a non-Apple monitor, and hope for the best....
    In the meantime, perhaps someone here could possibly explain to me why this piece of **** should die and then "revive" on me?...
    But, I'm so "******" that I've actually prepared myself for its ultimate and rapid demise, that perhaps, just perhaps, I'll be glad when it happens!...

    Hi Bob, I suspect it's the Backlight or the little Inverter assembly.
    When it's dark shine a flashlight in it and see if you see a dim Desktop.

  • 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!!

    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.

  • PowerMac G5 17" Studio Display Not working

    Hello All,
    My PM G5 tower's 17" Studio Display went blank today--no one saw when it blanked, so I don't know if it went all at once or slowly. The thing is, I don't know if it's the display or the video card. The PM is fine, since I can operate it via screen sharing. According to System Profiler, the card (GE Force FX 5200) is working and the monitor is connected properly and shows the correct resolution. I can't run hardware check since I can't screen share when starting from the DVD. Is there any other way to check to see if the problem is in the card or the monitor (other than hauling it down to the Genius bar)?
    Thanks,
    Lou

    Hi-
    If, in the case of an issue with the ADC portion of the card, often times there is no prior warning, as the failure is more often a power issue than VRAM or GPU.
    With VRAM or GPU, there would be visual warnings with pixel errors, banding, and other graphical artifacts.
    The system profiler is virtually worthless for detecting hardware failures.
    As for the display, the inverter board is not that uncommon of a failure.
    Typically, though, this is accompanied by a flashing power light on the display(short, short, long):
