IMac :: LCD Looks Burnt - Grey Blotches On Screen?
Dec 5, 2010
hopefully will be able to get some info on here as to what's up with my iMac. Over the last day or so I noticed my screen looking dirty, and have just left it. I went to clean it today and noticed that the "dirt" is under the glass, and on the lcd itself. The only way I can describe it is if you were to burn a candle with a bit of glass behind it, the glass would get like a grey/black residue on it, that's what it looks like. But, the problem is, it isn't uniform, it is in blotches, and it actually looks kinda like fingerprints. Like if you were to put your finger on the glass of the candle, it would take away the residue and leave an oval clean spot? That is just at the top left of the LCD, at the top right, it looks more like dirty water marks on the LCD it's self, again, the same colour.
It is only in the top half of the LCD I am noticing this problem. I wouldn't say it is yellowing, but is this a common problem with iMac LCDs?
I'm currently looking for the charger for my camera, but I'm not even sure if that will show it. My iMac is only 2 months old, if that, and I'm worried as to what might be the cause. Does anyone have any idea what could have caused this?
I have a first generation macbook pro, recently i have been getting neon green and purple blotches appearing on my screen. I was also having a hard drive problem so i swapped that out and installed a fresh copy of OSX 10.4 on there and was still having the green and purple show up so I know that it is hardware related. I also have hooked up an external monitor and they show up on that monitor too so I konw the problem is not related to my monitor.. I downloaded fan control and have found that if I keep my macbook under 53 degrees C then They wont show up nearly as often but they still do. The only problem with this is that to keep it under 53 degrees C then I need to have the fans running extremely fast the entire time which is not really solving the problem...any suggestions?
It kinda looks to me like I need to get the logic board replaced, what does that entail.. can I do it myself? im pretty good with computers and electronics. I don't have apple care and the warrenty has definelty been voided or is expired..what kind of $$ am I looking at?
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
This has been going on for a while. It happened first a month or so ago.
I turn on my 2008 iMac 24". The screen turns white like always, but no Apple icon appears. It starts to make a loud nice again and again. Bip, Bip. Pause. Bip, Bip, Pause. Bip, Bip. Pause.
I turn it off. Turn it on again. Same thing happens. Repeat.
I take out the cable powering the computer and go to school. I put it back in when i returned and turned the computer on. It worked fine.
Nothing happened again until a week after. I was sitting working on the computer, when it out of nowhere shows the "grey screen of death". I turn off the computer, take out the cable, leave it out for half and hour or so, then turn the computer on. It works fine. Works for a week. Same thing happens again.
Now it starting to appear more often tht though, and I'm afraid to turn it on until i get an external HD so i can Time Machine, in case it will appear more often for every time i turn it on.
The guarantee is not valid anymore (never purchased AppleCare) and i can't bring it to a store and show them what it does, because it doesn't always happen.
I read that it might a kernel panic somethingsomething, and that i need to wipe the HD. Though that was when the computer had the grey screen all the time. Not just occasionally like on mine.
Hoping someone can help - my imac (approx 15-18 months old , intel) won't start.
Last night on shutting down DPP (canon Digital image software) was hanging and system asked me if I wanted to force quit it...sadly I had switched off my bluetooth mouse and , as usually once mouse turned off switching it back on it never re connects - why did I buy the bletooth mouse and keyboard ?, so I could not confirm yes force quit - is there no way of selecting with keyboard like there is in windows ?
So I switched off at power switch. Tried to re switch on - grey screen came up, apple logo, the little timer circle but after a while timer circle stopped and nothing further happened.
have tried several more times and now don't even get timer.
24" imac. leopard system. the system was frozen (which was the first time in two years) a couple of days ago, so i turned the power off to reboot the system. then it's stuck at the grey screen. to make it worse, i have a dvd inserted in the drive. please tell me what seems to be the problem and how to solve it.
My IMAC will not boot up. It was working fine this morning and I was working away then suddenly a MUSIC file wouldnt play, so I restarted the computer, and this is what happens now...It starts out like normal but after a period of showing me the APPLE logo it goes to the "NO" symbol. url...
iMac os x Mavericks 10.9.3. I tried to boot up yesterday morning after completely shutting dwn the night before. Stays on grey screen with Apple logo. I tried safe mode, no luck, will not boot up in safe mode. I tried backing up to external hard drive from utilities, but it stopped and said something like couldn't perform function... I never used or set up Time Machine.
Not sure exactly when it started but I noticed it about half an hour ago and have come straight online to 'troubleshoot' the problem. The is a grey smudge/shadow in the middle of my screen and I am unable to remove it by cleaning the screen or restarting my computer. I have seen similar issues posted with no resolve so I don't know if people discovered a fix or just gave in and took the computer into the Apple store. With no way to transport the computer safely into the city centre, I would like to avoid doing that if at all possible.

I had been using my iMac all night, when all of a sudden the bouncing beach ball appeared and everything became unresponsive, apart from the mouse cursor itself. It might be worth noting that a few hours prior to this, I plugged in an external hard drive to burn off a DVD. This external hard drive has two partitions, the first being a restored image of Leopard; and the second, my out of date backup ("yes, I know").
I subsequently restarted my machine, enjoyed the chime, pondered the excessively long start up and looked bemused at the Leopard Setup wizard. I realised that the restored Leopard partition had booted up instead of the internal disc. So, I unplugged the external drive, pressed reset on the iMac and was immediately greeted first by the reassuring chime, then by the Apple logo and a lingering grey screen and finally by a flashing dark folder icon with a question mark in the centre for eternity.
I tried rebooting a few more times. Same. I've been frantically Googling but only found the PRAM reset and a very frightening iMac disassembly guide. I've tried plugging the external drive back it, but it refuses to boot Leopard from that now. What can I do? I feel so helpless on a Mac, on a PC I'd at least be able to open the sucker up before panicking! I've been working on a client's flash web dev project for months, and not made a back up in about half that time. The website is supposed to be going live tomorrow! Luckily I have the site uploaded, but the entire source code is potentially lost, so in the long term this is a major catastrophe!
There is a slight ghost of an image burnt on my iMac's screen. Luckily it's at the side of the screen rather than right in the middle. But am wondering if there is a way to get rid of it.
My Mum has just turned on our family computer- an iMac G5, 1.9ghz 17" (first model with built in iSight).
It gets to the grey screen with the apple, with the loading icon below it, then after about a minute the fans turn out pretty loudly, and it goes no further, just stays on the grey screen.
I shut down my imac and when I went to restart it, I can't get it to get past the grey screen.I can't even get to the apple screen.I have unplugged everything and nothing works.
Got my 24" 2.4GHz iMac on release last year, with Tiger. Installed Leopard on it on release day.
The problem I have is that ever since a botched Boot Camp installation I've had endless problems with certain applications hanging during their startup (notably Image Capture) or refusing to quit (notably iTunes). Force Quit doesn't resolve these issues. Restarting doesn't work because Force Quit can't quit them so I have to pull the plug or otherwise force a shutdown.
Upon restarting I either get the grey screen that instantly appears, or, if I've pulled the plug and left it for a few minutes I can get to the Apple symbol but no spinner or any further start up action. Occasionally I get lucky, get back up and running, and all is well until the next crash.
All this started happening when I decided to try installing Windows on Boot Camp again. I've had it on here a couple of times since Leopard was released but usually end up deleting it eventually because either the Windows installation gets bogged down or I get bored with it and never use it. Anyway, this time, using the same discs I've always used (and yes, it's SP2, so it should be fine and anyway it's worked at least twice before) when I got to the 'restart to continue installing Windows' bit, I got the white screen and nothing happened. After an hour or so of praying and restarting endlessly trying to get a response, I finally got it to recognise my OSX installation and was up and running again. The Boot Camp volume didn't appear to be there and Disk Utility revealed zero problems whatsoever. Everything looked fine until these recurring hangs, refusals to quit apps and screwed up start-ups.
Any ideas? I don't have the expensive Apple support, but it's less than a year old! Of course, I realise that this means nothing to Apple, who seem to think I should pay a premium in order to have my machine warrantied by them for more than 90 days. Grr...
If I get it up and running I'm thinking I should just wipe the ENTIRE system absolutely clean and re-install Leopard and then use my Time Machine backup to put all my data back on (pricelessly valuable as I use the machine to work on my photography with), but I'm concerned that if there's a flaw in the System somewhere, a corruption, that installing the Time Machine backup will just reintroduce the error. On the other hand, if it's a deeply embedded and invisinle partition corruption from the bad Boot Camp installation attempt, that should be fixed by wiping the entire drive to reinstall Leopard, right?
New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem.

I've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?
I have a HITACHI touro desk 3TB external hard dive connected to my iMac OS X version 10.6.8 Every time i start up the system it stays on a grey screen until I unplug the usb of the external hard drive then the system boots up normally. I have tried connecting different usb cables, plug in to different usb ports, and nothing works. I have other external hard drives and they don't give me any problems. is a pain plugging and unplugging the usb cable.
just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.
I've tried holding shift during startup - no effect. I've tried rebooting NVRAM - no effect.
I was trying to install Windows XP Pro, but for some reason the it wasn't showing another HDD to install Windows on. So I quit the install, and restarted my computer. Now all that happens is the normal grey screen appears (with no Apple logo), then it goes to a black screen and has the blinking cursor (Kinda like DOS).
Whenever I try to use Screen Sharing to control this one particular Mac Mini, and someone else is using the mini, and I pick "Connect to Virtual Display", I get dropped to a grey linen screen. Like the login screen, but without a list of usernames or anything. There it sits. Here is what I see in the console of the mac mini when I try and use a virtual display from the other machine:
3/10/12 7:30:04.291 AM mds: (Error) Backup: Couldn't stat source path '/Users/glados/Library/Saved Application State/com.apple.finder.savedState/window_3.data' -- importing from backup path instead 3/10/12 7:34:01.706 AM [0x0-0x9009].com.apple.systempreferences: System Preferences(148,0x7fff76017960) malloc: reference count underflow for 0x400440ce0, break on auto_refcount_underflow_error to debug.
grey screen no apple followed by blue screen with vertical lines. Graphics and logic board replaced <6 months ago. What to do? I held down shift, it gets HOT HOT and makes noises. (for safety mode) followed by a blank grey screen and blue screen. Then tried the other way (I think it's command alt delete? I don't remember) and it turned from grey (no apple symbol) to blue blank. Then third time, grey followed by blue with vertical lines, not blocky clear lines that you can see if you are close to it.
Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.

the gfx chip is a GeforceMX4 with 32mb.

before I went to bed, I was playing the Sims 2, when my iBook G4 crashed. Our power cord can be a bit dodgy, so sometimes that happens. I didn't really think about it much, just closed the laptop and went to sleep.Last Monday morning, I opened it and pressed the power button. It began turning on, and got as far as the grey screen with the apple and the spinning circle. And then it just froze. The circle stopped turning.
I freaked out a bit, and restarted it a bunch of times, each time with the same result. (One time it stopped spinning, and then told me a restart was required. Huh. The rest of the times the exact same thing happened though.) I even tried unplugging and removing the battery, but it made no difference. So eventually I just shut it and decided to try again later.Last Tuesday I opened it and pressed the power button without much hope, and again the apple and circle came up just fine, then stopped, but then a bunch of words and numbers popped up.I'm a complete computer noob, but they don't look good to me... or are they good?

-copied from time machine but not all got copied only some random files
--still all I get now is a grey screen, sometimes with a grey folder and question mark
-tried to copy individual folders as library etc to the mac HD but only a few get copied still just the chimes and a grey screen took out some of the 13 gig ram and juggled with that in case one is broken
