Any news on imac G5 20" screen dimming?

I have been living with the top half of my screen dimming intermittently for the past 4 months or so. The bottom half stays bright. I have to sleep the computer to bring it back and it's a pain. I brought it to the Apple store a couple months ago (my machine falls into the recall serial #s) and the genius said the capacitors are fine and that it was due to bad memory. I pulled my aftermarket memory - and it still does it. I saw a lot of people asking about this months ago but never saw any definitive answer. Thanks - 1st post

I had this problem when Apple replaced my screen for the "white banding" on the lower half of the screen. Take a look at these instructions for replacing the inverter. If your comfortable with working around the internals of the machine this may help.
http://manuals.info.apple.com/en/imacG5_20inchInverter.pdf
When you open the document it will show you the internals of the G5. If you go to page 11 it shows a little connector inside a little grey box. If that connector is not seated properly you'll get the half-screen dimming. All I did was reseat the connector and made sure all the twists were out of the cable to make sure there was no stress on the connector. It worked fine after that.
Good luck.

  • IMac 24" Aluminum screen dims like notebook

    So this is kinda weird. For some reason if I do not do anything for a minute (move mouse, touch keyboard) the screen dims like on the notebooks when they try to save power. Something tells me this isn't right... Anyone have any ideas or experiencing the something?

  • New 27" Imac with no screen dimmer slider and not responding to F1

    I hope someone has the answer to this. =)  I just purchased the 27" Imac that was an open box buy from Best Buy. When I opened it, it had Yosemite installed on it. I went to adjust the screen brightness (under the preferences pane) and there is no slider! I then tried the F1 & F2 keys.....nothing. All the other function keys work, but not those two.  I called Apple and was told I needed to take everything off and reinstall then upgrade to Yosemite. Fine....nothing.  I made an appointment to take it into the Genius Bar and they couldn't figure it out either.  I took it back to Best Buy and into the Geek Squad (then had to send it somewhere). They told me something I can hardly believe. They said the slider bar and function keys work in Mavericks (which I guess is what it came with) but once you upgrade to Yosemite, the slider and keys become unusable. So does this mean I can't ever upgrade?  Does anyone have a fix for this??? Please, please help me.  Thanks in advance.

    Thank you for your advice.
    I will use if the IMac will not we under warranty but since now it is still covered it is Apple's problem to fix it. Anyhow this is now the smallest problem since the Mac is not working at all.
    Now the problem is that I'm not in Korea until 20th of July and I will like to make the arrangements that my Imac will be taken for service asap. Unfortunately beside the phone number for service support that was not working before my departure and the e-mail address of one Apple worker (but not from support team) that didn't reply to my last e-mail I have no other contacts.
    I don't know where to send a complain or service request.
    I still hope that an Apple employee will read my post and will take action or that one member of the forum with the same problems in the past will provide me some hints about the Apple support service.
    Until then I try to enjoy my holiday.
    Tank you again.

  • It's 2:25p.m.That Means My New Intel iMac is Going to Crash!  What's Up?

    My father-in-law recently bought a new 17 inch iMac with a I Gig of Ram, running at 1.667 mz, the whole nine yards. Nice machine. He bought it on my recommendation. It worked good until it started crashing. He put up with it for a while. I told him he didn't have to do that. So he took it back to his Apple dealer. They ran diagnostics and then determined it was the logic board. So they replaced that. He brought it home and it continues to crash, screen going dark and then it asks him to restart. The bizarre part of it all is it happens mostly at 2:40p.m. to 2:50p.m. almost on clockwork. What's up with that?
    He's calling the Apple dealer tomorrow. They surely will tell him to bring it back in. Anybody have any ideas? This is a vexing problem, one that shouldn't be happening on a new machine.

    If it really always happens about the same time, a likely culprit would be a power problem caused by someone turning on a cooking device or heater at that time -- and causing a voltage drop or surge in the same circuit.
    Is your Dad noticing any lights dimming?
    Another alternative, if it is connected via wireless, would be some kind of radio interference caused by someone nearby who is on a regular schedule with using a microwave oven, cordless phone, or wireless computer.
    Again, it would be useful to know what programs you Dad is running at that time.
    And the timing might just be co-incidence, in which case the range of possible causes is a lot larger.

  • Anyone using a NEW intell iMac with Logic?

    I've got many great responses on both sides to my question regarding my quest to determine which machine to use with Logic -- new Mac Pro (the ultimate) or new iMac (likely cover my bases for a long while and save major cash now). One point raised against iMac was fan noise smack dab in the middle of the listening field with the older iMacs. So a sub question to my original is this:
    Are there any NEW intell iMac users out there who are using Logic? Is fan noise a problem? Generally, how do you like the iMac's feasibility as a music workstation with Logic? How many tracks/effects are you running and how is it working for you?

    Before those concerns are completely alleviated, go over to the iMac hardware forum and do a search for firewire issues. Like actual physical problems with the jacks on the 20" iMac and having drives just completely "disappear".
    the reason you will find issues including firewire ones on the imac forum is because it is a forum for people with issues. it may or may not be the case that there is a subsantial issue with FW on the intel imacs, but obviously people who are having issues are going to pop up there making it seem like everyone is having an issue.
    for certain types of music production, an imac would be completely unsuitable. but for others it will be ideal.
    there drawback of having 800 and 400 FW bus shared is that if you have a 400 device it will slow down 800 devices to 400. that means it would be ideal for impiro to have either both FW drive and interface as 800's or not go to any further expense of getting an 800 hard drive to use for audio since he would not beneift from the speed.
    not a great big deal IMO.
    iMac DOES lack expandibility, but it doesn't lack horses. actually i would say (and have said) that impiro would do better with an older tower to allow for expandability because he doesn't need that many horses to do what he needs to do. and i certainly feel that it is unnecessary to spend money on a computer that would be better spent on other things relating to the move to computer based music mixing.
    never-the-less, the kind of live musician-audio-based music impiro is going to be making is childs play for modern computers. he will be able to run loads of tracks and plug-ins before a new imac will even break a sweat. even with an interface and a FW drive on 1 bus running at 400. he just won't be able to run loads and loads.
    and man....even if he decides to get more heavily into it and start buying third party cards and this that and the next thing he can look at the next computer being a tower. personally, i am changing my computer every 3 years or less - it'll take him at least that long to find the ceiling on a new imac.

  • Black/Blank Screen with Boot Camp Win 7 Install on new 27" iMac

    I'm having a problem getting Windows 7 on a new 27" iMac and am familiar with the Boot Camp Windows installation process. Here's what I've done...
    1. Run Boot Camp from OSX, partition the drive.
    2. Insert Win 7 cd, proceed with installation.
    3. Computer restarts and the 'preparing for initial setup' message displays with the Win 7 splash screen. When it switches to where it should be displaying the Win 7 desktop, the screen is black.
    I can hear the Mac still running, but there's no display. It's like it's waiting for some type of user input for the intial Windows setup (haven't yet entered the key).
    I've done a hard shutdown and restarted Windows with the exact same result. After reboot, I get the 'Windows was not shut down properly' message with the 3 safe mode options, where choosing either gets me the 'Windows cannot complete setup in safe mode'. And any key reboots it.
    The Mac side still runs fine and holding the option key at start up gives the Mac/Win boot options.
    I'm inclined to think that it's a video driver issue since the 27" is brand new. Maybe Apple used a new video card for the larger screen and haven't updated the Boot Camp drivers. I checked on ATI's site for an updated driver for the Radeon HD 4670 they say is in the new 27" model that's currently available. (not the quad core)
    Is there any workaround for this? I was thinking of installing Vista instead, and upgrading to Win7 once installed, but if it's a driver thing, it would just be a long way to the same result and could have the same problem with Vista as well.
    Any ideas?

    I think I figured out what is happening here with the video drivers on the new iMac's and Win7. I believe it's re-directing the video to the mini display-port output when you see the screen go blank. I installed my Win7 x64 with no issues but I had an external monitor hooked up at the time and while it was installing the O/S my iMac went black but everything moved over to my external screen. Once it finished installing then everything went back to normal after a reboot.
    Not sure if that helps anyone but pretty sure that's what is going on. So if you have another monitor handy, get the mini display-port adaptor from Apple and connect your external screen before you install Win7. Cheers!
    P.S. If you have one of the new iMac's and want to install the latest Radeon drivers (after you have installed Win7 on your iMac), try the following. Download and install the drivers from ATI/AMD directly. They'll try to install and fail (no worries) but now the driver/install files will be unzipped into an ATI folder on your main Windows hard drive.
    Now go to this site: http://www.driverheaven.net/modtool.php and download the tool and use the Vista instructions listed on the main page of the URL above. You shouldn't need to download the MSXML 6.0 and I don't think you need to disable the UAC stuff like they suggest for Vista (I didn't) and it works fine. UAC is not nearly as intrusive on Win7 as it is in Vista so I think that's why it worked for me and pretty sure the MSXML 6.0 is already in Win7. Once the program has modified the mobile Radeon drivers then you can run "setup" from your ATI directory and the new drivers will finally install correctly including the Catalyst Control Center. Voila! I now have 9.10 drivers up and running on my new 27" iMac and working perfectly so far.

  • New 24" iMac Screen Brightness Problem

    My new 24" iMac's screen is much brighter on the left side than on the right. What should I do? Surely this is not normal for an iMac. Did I get a defective screen? Please help! Thanks in advance!

    I got a 24" iMac from Amazon and noticed the screen gradient after a few hours of use. Then I also noticed a stuck pixel in the middle of the screen. I was very bummed and after reading through forums I realized that this seems to be a common problem. I was getting prepared for 3 "geniuses" gathering around my iMac telling me that they can't see anything wrong with it and then me trying to sell it on ebay with a $500 loss.
    But things turned out quite different for me.
    I took the iMac to one of our 5! Apple Stores here in Houston and explained the gradient and the stuck pixel to the Genius. He turned the computer on, looked at it for about five seconds and says "yep", turns it off and starts typing away on his MacBook. Five minutes later I asked him what he was doing and he goes: "Oh, I'm replacing it." Me: "the screen?" Him:" No, the whole thing!"
    I was overjoyed, I almost couldn't believe it.
    They brought out a brand new box and I asked him if they would let me transfer my files. They agreed and handed me a FW cable. I checked the new iMac for any screen issues and it looked perfect. So I started the setup and let it do its thing. I decided to go get something eat with my daughter while the iMacs were transferring files. Got back an hour later and it was done. The new iMac started up in my user account and everything. But then I noticed a black dot that almost looked like a dead pixel but it appeared to be right behind the glass and not on the screen itself. I asked another genius (the first one had left) if he could remove the glass and try to clean it. Sure enough he went to get the suction cups and popped off the glass. The black dust speck was visible and easily removed. The glass got re-installed and I packed the new iMac back into the box.
    I expressed my feeling of satisfaction and headed home.
    At home I thoroughly inspected the screen again and it appears to be nearly perfect.
    I'm very happy now. Apple sells their products for a premium and I my case I received premium customer service. Way to go!

  • New 24" iMac - darker backlighting at edges of screen

    Hi, I was just wondering if it's normal for a new 24" iMac to have uneven backlighting at the edges of the screen? All the way up and down the left and right sides of the screen for about half an inch the backlight is dimmer than it is on the rest of the screen. It is more noticeable at the bottom left and right corners. There's also two stuck pixels in the bottom left quarter of the screen - one is stuck red and the other is ok unless it has to display the colour blue in which case it just appears black.
    I know stuck and dead pixels are possible on any display, but what about the backlighting? Has anyone else experienced this on a 24" iMac?

    Following my previous post, the repair shop fitted the third screen under warranty and that screen too had dead pixels.....So this is two brand new screens with dead pixels now... Apple quality? I have contacted Apple direct and asked for a replacement computer as I have no faith in their ability to make repairs and they refuse, though the machine was under a year old when it first went in for repair with the screen problem. So from my point of view, poor quality hardware and poor quality back up. Thanks Apple, I am still waiting, whilst you continue to attempt repairs, this is surely the last product I shall buy from your company.

  • IMac screen dims itself automatically; all attempted fixes fail; how can normal brightness be restored?

    Machine and OS:
    2007 white plastic iMac with 20" screen and 2 GHz Intel Core Duo, running OSX 10.6.8.
    The problem:
    The screen dims itself for no known reason. It is especially noticeable when waking from sleep: for the first second or two after waking up, the screen is at normal brightness -- but then after a second the computer seems to "remember" some setting or command, and the screen unquestionably dims itself to be about 20% or 25% darker.
    Because the screen for a brief moment after waking is at full brightness, that proves to me that there is nothing physically "broken" about the display that prevents it from illuminating fully; it could be at full brightness if it "wanted to," but some kind of software or firmware glitch is telling it to be dimmer.
    The fixes I have attempted so far -- ALL of which have FAILED (so please don't recommend them again):
    - Reset the NVRAM or PRAM by holding down Command-option-P-R upon startup. For some reason this technique doesn't cause the second chime, so it doesn't appear to be zapping the NVRAM or PRAM or whatever, and consequently has no effect on the dimness, which persists unchanged after restarting.
    - Reset the NVRAM using the terminal command ' sudo nvram boot-args=”-p -r” ', as recommended on this page: https://discussions.apple.com/thread/2172681?start=0&tstart=0. I can't tell if this really did reset the NVRAM (it doesn't cause a second chime upon restart), so I'll just have to assume that it "worked" -- but except for one instance, it had no effect on the screen dimness. (That one instance went like this: after issuing the Terminal command and restarting, the screen did go back to full brightness -- but only until the first sleep. After waking from that sleep, the screen once again dimmed itself as before. And no, I have not been able to repeat this momentary "success"; on all subsequent attempts following the exact same steps, no brightness has ever returned at all since.)
    - Reset the System Management Controller (SMC) as recommended on this page: http://support.apple.com/kb/HT3964 . Basically this just entailed shutting down the computer waiting a few seconds, then unplugging it, waiting a few more seconds, then plugging it back in, then waiting a few more seconds, and then finally starting it up again. Result? No change: screen still dims itself.
    - Pressed the "brighter" and "dimmer" keys on the keyboard; those do make the brightness go up and down, but the top brightness setting is much dimmer than it should be (and used to be). All the way to brightest setting = still noticeably dimmer than normal.
    - Used  the "brightness" slider in the System Preferences > Displays > Display window. That also does indeed adjust the brightness up and down, but as with the keyboard brightness keys, the highest setting is still too dim.
    - Readjusted the "Calibration" in the System Preferences > Displays, which had no noticeable effect; even when going into Expert mode and adjusting every little aspect of the screen display's default settings. Those all seem to be about color balance anyway, not about brightness. I now have three different new calibration settings, and clicking back and forth between them and the default setting makes no real significant difference. Whatever setting I choose, it is still dimmer than it should be, even though in all my attempts at calibration I tried to make it brighter.
    - Tried going to System Preferences > Universal Access > Seeing and adjusting the "Enhance Contrast" slider and trying out "Black on White" vs. "use Greyscale"; none of that helped, and did not seem to be relevant to the problem.
    - Tried going to System Preferences > Energy Saver, and clicking the "Automatically reduce the brightness of the display before display sleep" check box on (and then closing the preference pane) and then off again (following the advice at http://support.apple.com/kb/TS2309?viewlocale=en_US) -- but it had absolutely no effect whatsoever on the brightness level.
    Final note: The keyboard and mouse are both Apple products and work perfectly, and the machine has no other performance issues. Just the dimming, which started a few weeks ago inexplicably and without warning.
    I can't imagine what is causing this problem, and I've absolutely run out of ideas about how to fix it. One thought I had was that maybe the screen is dimming itself due to detected ambient illumination, but I'm not sure 2007 iMacs even have that feature, and also the screen remains dim whether the room is dark or bright. Maybe there is an ambient light detector somewhere that is malfunctioning?
    Help! How can I solve this? The screen is not so dim as to be unusable, but it's annoying enough that I'll have to get a replacement machine if this is not fixed eventually.

    Does an external display also act in a similar manner as the internal one?
    Some earlier Intel-based iMacs had graphic processor card issues; not sure what
    the symptoms of the majority of them were, but some had odd patterns, others
    went black, and some would range from OK to totally unusable. Among others.
    So there is a chance the graphic processor may be going out; or just the circuitry
    that controls the backlight. An inverter may be weak or other circuit to the display
    could be wearing out.
    http://www.apple.com/retail/geniusbar/
    If you have access to an Apple Store with Genius bar, they can perform some kinds
    of diagnostic tests there even though the computer is out-of-warranty; that may be
    of help to narrow down the cause of the symptoms you've noticed. They may not be
    able to repair it, however, at an Apple Store; as it is rather old by today's standard.
    An Apple Authorized Service Provider could do repairs and testing on older models
    the Apple Store's Genius and other may not be set up to handle due to vintage.
    Find an Apple Authorized Service Provider
    Visit an Apple Retail Store
    There is a country locator page to help find either of the above in regions outside
    of the US & Canada, not sure how the above links would work; and it appears my
    bookmarks to the country locator page may not be accessible now to post here.
    You may be able to get an idea about what kinds of parts support the display
    function by name by looking into an iFixit.com repair guide for your iMac series.
    Hopefully the parts supporting the display are the reason it is dimming down, as
    a graphic processor failure likely would exhibit other behaviors than just dimming.
    PS: I see you've added content to your thread after I'd started working on this
    & the answer likely is a hardware repair; professional testing is worth the time
    and you seem to have at least one other thread on the same topic....
    Good luck & happy computing!

  • IMac 21.5" Screen 'flutter' when screen auto dims'

    Hi, I have a brand new 21.5" i7 with 8GB Ram. I noticed the other day that when the screen dimmed the whole panel seems to flutter, I also noticed that auto dimming never dims below a certain point and remains really bright, even in a dark room, yet my friends snow leopard variant has none of these issues and dims all the way down. I didn't want to keep a machine that's just over a week old if its defective but are these lion bugs or is it hardware? I was wondering if anyone with Lion is having similar issues, My machine was not an upgrade but came with 10.7 installed.

    It's out of Applecare/warranty by a couple of months and I cant afford to pay for it myself, any point in taking it to apple?

  • Has anyone seen the new 2012 iMac in any Apple stores yet?

    I was told by an Apple store employee that they would have the new 2012 iMac's in the Apple stores with-in a few days of their launch announcement, back in late October .... here it is late November and the new 2012 iMac's are not yet in the Apple store, for display purposes, here in Rochester, NY.
    Last night I was again at the Apple store here in Rochester, and asking about the new iMacs. one of the employees now says they "may be out in December" some time.
    I'm very disapponted as a loyal Mac user for over twenty years (and even as an Apple investor). that Apple is announcing the launch of these new products, and then taking months for these products to show up for sale.
    I'm starting to think that it won't be until late January that I can actually be able to purchase one of the new 2012 21.5" iMacs ..... i've been waiting years to get a new "antiglare" iMac.
    Has any one actually seen one of the new 21.5" 2012 iMacs in one of their local Apple stores, on display yet?

    UPDATE: Dec. 6, 2012
    I was just over at the local Apple store loking at the new 21.5" iMac, and to be honest, I wasn't all that impressed. I have been waiting for over a year to upgrade my Mac, and had high expectations for the new 2012 iMac's .... but seeing and playing with one in the store .... the new one's may not be for me.
    Most of all I wanted to believe all the talk about 75% less reflections in the new iMac display, but while in the Apple store, I saw no real difference over the previous model ... and if so, it was more like 25% less reflections. Nothing that dramatic, certainly not like the "anti-glare" screens available in the 2011 MacBook Pro. Basically, my understanding is that the new 2012 iMac's use the SAME DISPLAY as the previous iMac models did. It's the LG "LM215WF3" display, same as those in the 2009-2011 iMac displays. The only difference in the 2012 display, is that they took out the small space between the outer glass and the actual screen surface to get the overall display thinner. It still has the basic "glossy glass" cover screen.
    The other disappointment was the extremely poor audio sound from the new iMac's built-in speakers. They just sounded so "tinny", even when playing with multiple iTunes "equalizer" settings. Again, disappointing.
    Looks like I'll have to research the possibility of buying a Mini-Mac and an older Apple 20" cinema display off eBay. Or pick up a late model 2011 iMac and get the Rad-Tech "anti-glare" screen film for the display (Ugh!).
    Being a graphic designer and art director in profession, I just can't understand why Apple has abandoned the "professional" market for these glossy displays in it's iMac line .... or at least STILL hasn't given us an option for a true "anti-glare" display.
    Is it just me, or are my observations on the new 2012 iMac being seen the same by others as well?

  • Just got the new iMac. The screen keeps jumping to the launch pad screen randomly when I am working in other applications. Please help.

    Just got the new iMac. The screen keeps jumping to the launch pad screen randomly when I am working in other applications.
    I have the magic mouse, don't know whether it is something to do with that? Any ideas?

    If gumsie's suggestion isn't the answer, try logging into another account, like Guest, and see if you get the same behavior. You may need to clean the windows on the bottom of the mouse.

  • Hi,,does the new 2011 imac 27 inch U.S version  support any pal signal inputs as video or hdmi through the video recorder device or kanex xd ?

    Hello,,

    does the new 2011 imac 27 inch from USA support or lay any PAL signal ??
    as for example
    I have a friend who lives in the middle east &  has kanex xd & he wants to connect it with the imac 27 inch from Satellite receiver  or PS3 though HDMI cable,, but yet the signal is PAL not NTSC in the middle east,, so will the imac 27 inch play the movie from the satellite in full colour or in blue & says cannot play the movie because its not NTCS ?  because this is U.S version  of imac then he might need an convertor?
    the same as if he want to record any hdmi or analog  device from his video recorder  device,,but the input is pal,,so will it plays normal in the U.S machine or will he find any trouble ???
    so can you pls give me an advice for him
    should he buy the imac from the U.S store or the europe store ??
    N.b : there is no mac store ONLINE in the middle east espicaly in Gulf, thats why he want to buy the imac from the mac store online,,

    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process.  Since I did that, my MBP boots up just like normal.  No flashing yellow screen anymore!!   
    (Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
    Let me know if this works for you!
