Allright, I have a 24" iMac. 3.06 Core Duo 2 4GB RAM etc etc.
Just now, as I was innocently talking to a friend using iChat, the top of my screen flickered once or twice and then went dark. I am typing on it now, so it is not unreadable, it just looks like the back lighting has gone off on the top half. The middle is relatively light (bleedover from bottom back light?). I have tried playing with the hinge to no avail. After I reset the computer, cleared pram-nothing. Zippo. I got the top to stay lit for about a half second after reset, but it then flicked off again. Do I need to load up my iMac and drag my ass to the Apple Store (it really is quite a task to drive there)?Here is a horrible cell phone picture (and no, the screen IS dark, that's not a shadow.):
I started up iTunes, checked my email, and looked up to see the top half of my display drop about 15 shades darker than the bottom half! I called Apple Care who told me they had never heard of something like this before and advised me to call the nearest Apple Store. I did, and like Apple Care, they had never heard of this happening.
display on my iMac 27 (bought in august 2011) have many dark spots. This is my display: url.. Could i replace my mac if i don't bought apple care? I live within USA and don't have Apple Store
I replaced my iMac G4/800 17" hard drive that was failing (S.M.A.R.T. status) tonight. Textbook operation, following directions from xlr8yourmac.com. No problems at all. I pre-built the drive with Tiger 4.10 in an external case (using the iMac as host) and transferred everything to the drive and tested. I booted off the external drive for a few days for testing. Again, no problems.
I got the iMac back together and booted up. Everything sounds fine but the monitor is black. It's as if there's no power to it or perhaps the lamps were just out.
When I press the power key for 1-2 seconds, the mac goes to sleep and the white Sleep Light on the front of the monitor comes on, so the monitor would appear to be getting power.
The Mac is working, evidently, as the chime for new mail sounded and the new drive chirps a little (very quiet though, btw).
I do NOT have a second monitor to hook to the VGA port, unfortunately.
On one reboot there was a sine-wave 'bong' sound, but the Mac proceeded to boot. I shut down again after that, took the housing apart and checked for trouble. Nothing. The video cable and connector is fine. There are no cables pinched or cut that I can see. And I did ever-so-carefully align the two halves when reassembling.
On the third boot I got the normal Mac chime (no bong/gong) and it booted fine - with no video.
One side note that I expect to be un-related: I left the HD jumper in cable-select mode, as the drive that was in there was also set on cable select (was a Western Digital 250GB drive; the new drive is a Maxtor).
How many others on here have an imac with burn in problems? I have a tone! I am so unhappy with this product. I am happy I have the extended warranty, I am now getting a new monitor for my imac.
I can barely see digital pictures and the likes. But websites and such i can see fine so long as the colors are light and looking on this site... [URL]
the first image i absolutely cannot see, it is 100% pitch black.. the other bellow it shows up just fine. But the two left/lowest squares on the color table on the very bottom the page both appear the same shade of pitch black.
I can see light but not dark. I tried callibrating and adjusting brightness and contrast.
Since to switching to an iMac from a PC, I have noticed that all of my images while looking great on my monitor print out way too dark. I had to actually record an action in Photoshop to adjust the images prior to printing. I could not understand why and just figured well it is what it is and not much I can do about it. However, on reading the June issue of Shutterbug magazine, there was an article in there in which they specifically mentioned the iMac,and the problem that was being experienced by everyone, professionals and amateurs alike with the "dark" prints, and put it down to the fact the iMac monitor was too bright ergo the issue with the dark prints.
Has anyone found a way around this rather than having to adjust the image way out of range in order to get it to print correctly and then revert to a prior state? Please. PS - I am using an EPSON R220 and an EPSON 1400, both of which printed fine with my PC. (OK Mac lovers, don't jump down my throat. I love my Mac. it just has a few quirks - like all computers - that need to be unravelled.)
My iMac has these dark spots on the screen and I wanted to confirm that it is a hardware issue before I make an appointment with an Apple genius. I thought it was dirt, but cleaning it didn't do anything.
dread going to work and use pc all day. anyway the only issue i have is every so often i will be working away and my whole screen goes blank for a second,,freezes. I have to tap the mouse to get it to come back,
I have a late 2007 20" Alu iMac and when ever I watch videos they appear too dark. I have tried changing all the settings I can find and nothing helps.
Its ok if I use VLC as I can change the brightness within the program but anything else ie quicktime, youtube or other embeded video always looks way too dark.
Has anyone else encountered this or is there something out there that I can do do brighten the video image?
So after giving up the new iMacs after two replacements about six months ago for yellow screens......I thought I would try again.
The good news is that the white is very uniform with no yellowing. The bad news is that it has this dark band across the bottom of the screen just above the dock.
So I am basically in the same spot I was six months ago. Replace the unit for a new one, replace the screen, or just live with it. Maybe I am being too anal but for $2,500, I shouldn't have to live with anything but a perfect screen.
My screen has gone to a very dark grey on startup. I can faintly make out the desktop icons, but it is about 98% black. Everything else seems to be fuctioning. iMac G417" Flat Panel 17" [Pixar-lamp style] OS 10.4
I have a G5 that developed a fault where half the screen is grey . It does this on starting up and stays this way. My eyes feel like there bleeding from hours of starring at screen and reading text to no avail. I am of limited funds so a send away for repairs is probably going to be beyond my means.
When I start typing on my imac after a few letters it freezes and background goes dark grey.Need to click on last letter with cursor to get it out of grey.
I have a question (whoa). I have an iMac Dual Core, bought in mid-2007 (it's the White Plastic version, not the newer Aluminium with the glass-display).
For some time now I had some dark spots, kind of shadow like in the bottom left corner. I wasn't bothered too much by them, but they got bigger, and now I have these in all of the corners except the bottom right one.
Anyone got any ideas how to get rid of them? (no, no three-year guarantee plan ... stupid me), or if not if it'd mean to replace the whole display or if it's just some cleaning (I talk money-wise here ...)
I attach two not-so-good pictures (the background is plain-white and the image is a bit enhanced ...) so you guys can see what I mean.
I sent an email to Steve Jobs about my yellow tint 21.5 iMac issues (three exchanges, all affected, resulting in a refund). I got a call from Dena at Executive Care within 24 hours.
She said they are aware of the problem and do not know how widespread it is. According to Dena, the issue is not resolved and that ordering a new iMac will not result in a fixed display.
She said the engineers are working on it now and they are not sure if it's hardware (most likely) or software related. Further Apple stores cannot do repairs because they haven't determined what the issue is.
I'm trying to using my iMac wireless keyboad for my macbook pro while my iMac is in external display mode but I can't get the keyboad to connect. I've tried disconnecting the wireless keyboard from my iMac but it won't go into target display mode without the keyboad. Can I used my iMac wireless keyboard with my Macbook pro while my iMac is being used as an external display?

I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.
I've had a 24" iMac (alu) for about a year. Now I bought a Mac Pro (Love it!). Therefore i wanted to sell the iMac, but:
All the time I've had it, dust has been building up inside the screen. I thought it was inside the glass cover, but I carefully removed that and cleaned it and the surface of the LCD element. That didn't do it...
From what I can see, the dust is inside the LCD element. Building up on the white lit surface behind the LCD crystals. (See the attached image).
This is my first led-backlit display and the first big glossy display I have used. First of all, the display is amazing because of how accurate it is and I love using it. Then to the question:The display is sort of alive, stick with me i'll try to explain it as best as I can, english is not my native language It kinda makes this very little brightness pumping that old crt tv's and monitors did. Same kind of effect but in a lot smaller effect, but you can sorta notice it's there. I have had none of those display image disappearance/flicker problems at all, display is working very well but I'm wondering if this kind of effect is normal with LED displays and does the glossy display enhance it/let more through? I'm thinking this might add to eye strain in long use but not sure(just like crt's did).
I have the mini display port plugged in and a vga cable from the imac to my external monitor. I should just be able to turn the monitor on and it work but the imac doesn't detect it and it just comes up as a black screen.
My six years old MBP OS 10.4.x Tiger all of the sudden the display turned black. I hardly see the content of the desktop only when there is some light on the room, looks like I have reduce the light to the Display. I have tried to reset the PRAM with the opion, ctrl, P, R key combination and it did not work. It boots-up OK, no problem with the HD neither Memory, I have not run any test on it though. I have not had any trouble on my MBP until now and I have to say I have never reinstalled the OS.
Need advice from those people buying an additional display to use with iMac 27.
Would you buy a smaller 24 inch iPS panel like Dell U2410 ($475 incl tax and shipping) or a 27 inch LED/TN panel (around $350 - 450) with the same size? I can also buy HP 2710M TN panle for $300
I'm not doing anything related to the Photo stuffs but Coding/Programming. So the Text should be crisp and clear ,easy to read .
Budget around $500, Please recommend any good 27 display that can meet my requirements, if you think I should go with the same size with my 27 iMac.
