IMac :: 24" IMac Screen Flickers During Screensaver?
Jun 19, 2008
So I've had my 24" Al iMac ever since November 2007, good and everything until the past couple days, after extended use of the imac, everything is fine, screen is great, but when entering screensaver, its still great, its like a couple minutes or so into the screen saver when the top of my iMac's screen starts to flicker! When I move the mouse to get out of the screen saver, every thing is back to normal. It happens with all screen savers.

I purchased a lovely 27" iMac yesterday. I have installed Windows 7 64bit on it and apart from a few quirks everything is running very well.
One thing that is bothering me is the Windows7 screensavers and power-management... they never activate. The power-saving features of Windows 7 don't seem to work at all. I did an install using the new "late 2009" drivers on a USB thumb drive during installation of Windows 7 so I think I've done everything properly.Is there something else I need to do in order to access Win7's power management features ?
Also, I've noticed that the Mac drivers for the ATI 4850 onboard graphics do not offer me the full range of resolutions (there are only a few options at the moment, the full native res, 1280x720, 1920x1080 and 800x600). How do I get access to the full range of resolutions ? Can I install ATI Radeon drivers and use those instead of the Apple supplied drivers ?

My new i5 iMac has been really slow after I get out of its screensaver or take it out of sleep. Even if its on the screensaver for a minute, moving the mouse causes it to freeze and try to load the desktop. This takes about a minute before my computer is fully functional again. Also, I don't know if this is just me thinking this or if its actually a problem, but the computer seems a lot slower than my previous, a 24" 3.06Ghz iMac.
Another thing, the fans seem to spin a lot more with this computer. Watching a YouTube or Hulu video makes the fans spin a ton. I've never had that happen with a Mac before. The computer also gets literally too hot to touch. Anybody else have this?
Also, on a (kind of) unrelated note, Windows performance with this is horrible. I've tried Windows 7 and Vista, and both run... adequately. The fans also spin a ton in Vista (what I currently have installed due to there being no 27" drivers for 7 yet).

Last night I installed Bootcamp on my i5 17" IMac and everything works except the screensaver and power management stuff won't kick on. For reference, here is what I did so far...
Setup Bootcamp Partition
installed windows 7 64 to that partition
used external display because of the video issues to finish the install
let windows update download/install all drivers/patches (which fixed the display issue)
installed bootcamp drivers from osx dvd
uninstalled bluetooth drivers so my apple wireless keyboard would work again.
I know that Bootcamp isn't supported for Windows 7 yet but does anyone know what is causing this or perhaps a workaround until official windows 7 drivers are available?

When my IMac goes to sleep, the screen saver is "frozen". The only way to get to my login accounts is by "cleaning" the screen with my mouse. It's as though the screen is not refreshing itself after going to sleep and whatever the last image was, it stays. However, it's not locked up or anything. I just need to move my mouse around over the login accounts and it slowly clears away the screen saver so I can see where to click to log in. I've tried disabling the screen saver, but have the same results. Something is causing the last image to freeze on the screen when the monitor sleeps.

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

My screen just started to occasionally have a flicker of a white line show up...It doesn't happen that often, should i worry? Is it worth taking it into apple? (Under warranty still) Since its not consistent i wont necessarily be able to show them what its doing..

I'm sure this should be simple but I can't figure it out.
I have my iMac connected to my TV and am using Plex to watch stuff on the TV.
What I'd like to do is turn my imac screen off without turning off the second monitor output (i.e. tv) as the imac screen is a bit bright/distracting (even on lowest brightness) when watching in the dark.

Last night I was working in Adobe InDesign and Photoshop when my screen began to flicker like crazy and eventually froze. I could still move the cursor around but nothing would work. I couldn't force quit any of the applications or shut down the system. It eventually shut itself down and after restarting everything seemed normal. About 20 minutes later it did the same thing as I was switching between Safari windows using Expose'. (I recorded a small clip of the flickering and put it on youtube if that helps: [url]...?v=UBjRwRu4IOg ) After the second time this happened I again tried to start it up and it loaded to a gray screen, no startup chime, no apple logo. Nothing. I hit the power button and it shut down again. And the next time it booted all the way. I then shut it down with the intention of calling Apple Care today but apparently my Apple Care ran out in the last month or so. So, I'd have to pay $49 to talk to them about this issue. I thought I'd come here first.

I'll cover the background to when this started happening.
I took my macbook out of an outer case to clean the shell itself.
I used wet ones which have alcohol so I wasn't worried, but also wasn't careless.
I once got a screen that said I needed to restart my computer. So I did.

Whenever I move my macbook on my desk with the lid open, or when I open the lid, or when I close the lid, my screen flickers to black and then back open many times. Is this a weak connection some where? Sometimes the screen will stay black until I move the lid a little bit. I bought it refurbished from Apple this spring. I do not have applecare.

I bought a 22 inch monitor. its a pretty generic brand, but its very high resolution and works great on other computers. i got the vga adapter for my aluminum macbook (i posted in this section because its closer to the 13" mbp). i have an apple keyboard connected to it. i try to use it in clamshell mode and when i press a button on the keyboard to wake it up the screen just flickers as if its trying to adjust the resolution. strangely enough, it works perfect in mirror mode. anyone have an idea?

I'm using the MiniDisplay port to HDMI on my MacBook Pro and connecting it to my 720P Dynex HDTV.
All my MacBook Pro does is flicker 3 times for about 8 seconds that it goes back to normal.

She has a 2008 Aluminum MacBook, the standard 2.0Ghz model. Occasionally when she moves the screen or tries to angle it, it flickers. This doesn't happen every time.
I honestly haven't tinkered with any Mac laptops once the unibodies came out, so I am hoping someone can shed some light, give some advice, and maybe throw out some ideas for repairs.

I understand these machines burn images into screens sometimes, but they fade back to normal after a while. My issue is that its taking less and less time to burn images into my screen. It's so bad, I avoid using the left side of the screen because simply leaving anything there for a full minute burns the crap out of it. Oddly, this only effects the left third of the screen.
I remember taking it up to an apple store (not fun, considering none are near me. The address their tech support gave me actually went to a pawn shop.) but they simply told me to leave the itunes visualizer running every now and then.
Back then it was just mildly irritating. Now I cant do anything with that side of the screen! Would replacing the LCD resolve this issue?
Below is a picture taken from my motorola razr. I know it's bad, but that's all I have.

This may seem odd, but I think my iMac is melting. I started to clean my iMac with a simple cleaning cloth then i realized spots on the screen. The aren't really visible when the screen is on, but you can still kind of see them. Not only that, the quality of the images on my screen seems to be deteriorating. It is only visible under light. I have attached some photos, but i wanted to know if anyones iMac has done this before(regardless of size, but post it in case), and if apple will fix it?

I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

Just now I was posting an add on Gumtree trying to sell my iMac, then I went into Dashboard to look at some notes and noticed some black indent- like text, from the Gumtree add. Is this screen burn?
I had a quick search on Google and found out that this happens more in cold environments. My room is very cold at the moment, but I haven't had anything like this happen before.
So, is this something that Apple can fix if I send the iMac in? It's still under AppleCare.

Sometimes when my screensaver kicks in the display never goes to sleep. Instead, the dancing screensaver, which is clearly running, is sucking up CPU and running hot for days. When I finally sit down and move the mouse, the pointer moves but the screen refuses to wake. This is a fairly new iMac, no mods, no programs installed of questionable nature, virtual new sock OEM iMac. Thinking about downgrading to SL as this is one of many problems that I have with Lion (not just on my machine but every Lion box). Has Apple peaked yet? Can we expect nothing but trouble from here on out?

Is there a way to make the login screen come up after the screensaver has been on? What I'm trying to do is allow my kids to login to their account, when I haven't logged out of mine.

I set her password and set the preferences to require a password to log in.Now, if she's not at the computer a while the screensaver kicks on, and after 30 minutes it kicks the logged in profile back out to the login screen. The problem is the screensaver never resumes?Even if I set the S.C to 3 minutes, manually log out to the login screen it'll sit there and show that (never go to screensaver or powersave mode for the monitor).
