| 27" 2.8 Quad i7 1TB | After 1-2 hours of use, screen flickered for few time, quick screen blackout occured, worked fine for few more hours and happened again. | |
| 27" 2.8 Quad i7 1TB | Immediately after using my brand new iMac for about ten minutes I began noticing a white bar flashing horizontally at random. The problem progressed into the entire screen flashing black. | |
| Jan Sampermans | 27" 3.06 Core2Duo 1TB | Screen distortion/flicker somewhere random in the screen (feels like it is more in the lower part) that looks like a horizontal bar of about 2-3inches just popping in and out of the screen. |
| 27" 3.06 Core2Duo 1TB | Screen has flickering and going black. | |
| robotkiller | 27" 3.33 Core2Duo 1TB | I could work for hours on the computer and then suddenly it would flicker randomly with a band of horizontal static bars about 3 inches thick momentarily or, alternatively, it would black out for a fraction of a second (happened every 5-10 mins). |
| capricia | 27" 3.06 Core2Duo 1TB | Since this morning my display of my 27" iMac show the menubar in the middle of the display and above there are a lot of vertical lines in multi colors. Now I think this one is not a problem with the driver, I think there is a problem with the graphic chi |
| jmczaja | 27" 3.06 Core2Duo 1TB | After waking the iMac from sleep I began to see this flickering problem. The machine was not hot whatsoever so I dont think the issue is heat related. |
| artka | 27" 3.06 Core2Duo 1TB | I turned it on and the flickering and menu bar on the top portion of the screen is happening. It does this for roughly five minutes then it goes to normal? |
| pschaf | 27" 3.06 Core2Duo 1TB | Seems to be getting worse. Quick flicker of bar at the lower half of the screen. No real way to reproduce. Have tried restarting and also sleep. |
| pschaf | 27" 3.06 Core2Duo 1TB | Last night i watched a 30 min programme on BBC iPlayer and the 2-3 inch white lines kept popping up every few seconds horizontally across the screen. The screen also went black momenterally on 6 occasions. |
| billybuds | 27" 3.06 Core2Duo 1TB | momentary black screen and the flickering. Seems to be very sporadic, won't happen for a few hours and then seems to happen every 20 seconds or so. Also the computer sometimes won't wake from sleep |
| Gable31 | 27" 3.06 Core2Duo 1TB | Screen has flickering and going black. Have called Apple tech support to begin replacement process. Makes me question the life span of the LED screen technology. |
| MarkyJ | 27" 3.06 Core2Duo 1TB | This morning it started to get worse and I also got he menu bar 2/3 down the screen, with the vertical 'barcode' look above it. The mouse moved off the bottom of the screen and re-entered on the top. |
| Jorel | 27" 3.06 Core2Duo 1TB | (flickers, blackouts, line , displaced screen, ...) and the slow wifi issue |
| ichbinglitched | 27" 3.06 Core2Duo 1TB | mine flickered on first boot (on the "select your language" screen) a few days ago and started spazzing out completely |
| mactoubib | 27" 3.33 Core2Duo 1TB | It is easily reproducible, by just activating the screen saver arabesque or activating TimeMachine. |
| QuickbookMDD | 27" 3.06 Core2Duo 1TB | this problem occurred nonstop upon first boot up. I had it plugged in a power strip with a 2 macbook pro's as well. I then put the 27" in a new power strip on its own with its own outlet with nothing else plugged into it and this problem hasn't reoccur |
| frodo20 | 27" 3.06 Core2Duo 1TB | It happens mostly when I switch on after the display has been asleep for a while. |
| stevo77 | 27" 3.06 Core2Duo 1TB | I then left it switched on over night and when I woke it from sleep this morning the screen started jumping up and down and displayed horizontal lines at the top and bottom. |
| McLaurin | 27" 3.06 Core2Duo 1TB | My screen (iMac 27") is fine UNTIL I go into a more graphics intense process. If I go into PhotoBooth, turn on some effects .. then BAM, there go the flickers. Flickers (plus screen going black intermittently) continue until restart, even if I quit |
| Goldfrog | 27" 3.06 Core2Duo 1TB | The first thing I noticed was a single white line going from the top to the bottom of the screen as I shut down... noticeable on the blue screen. And it went black a couple of times. |
| Peter Nuding | 27" 3.06 Core2Duo 1TB | Mine was fine for the first week now, but tonight it suddenly started doing this, and quite often so, i get about 3 to 5 of the pixel-garbage flickers per minute and the blackout every 5-10 minutes |
| rmp09 | 27" 3.06 Core2Duo 1TB | I have the same flickering problem the moment I turned on the computer for the first time. The screen goes black for a microsecond at times as well. It has been intermittent. |
| Michael Hanscom | 27" 3.33 Core2Duo 1TB | occasional 'flickers' of static bars across the screen, sometimes the screen blacks out entirely for a half-second or so, and twice I've had the desktop 'shift/wrap' downwards, showing the menu bar about three inches below the top of the physical scr |
| AstonMartinDB7 | 27" 3.06 Core2Duo 1TB | I get the same symptoms rebuilt the OS several times following a driver problem for my printer and thought the flickering had gone but it is back with the lines and black screens! |
| gustaven2000 | 27" 3.06 Core2Duo 1TB | Sometimes the screen completely blacks out for 2-3 seconds on intervals of 5-6 secs and the machine becomes useless. |
| lordrobert | 27" 3.06 Core2Duo 1TB | after about 35min I got the first flickering. And it keeps returning irregularly. |
| jogness | 21.5" 3.06 Core2Duo 1TB | I have a new 21.5" iMac (ATI Radeon HD 4670) and am experiencing the exact same flickering issue |
| opeddler | 27" 3.06 Core2Duo 1TB | started about a week after i got mine |
| StileselitS | 27" 3.06 Core2Duo 1TB | I got my new 27' and problems started immediately - screen flickering. |
| kawo | 27" 3.06 Core2Duo 1TB | After replacing the ATI graphics drivers the flickering is definitely gone on my machine. |
| fredpontes | 27" 3.06 Core2Duo 1TB | I got my Imac 27 1 week ago and the problems started 2 days ago. I had the white lines and some blackouts. |
| bfreebody | 27" 3.06 Core2Duo 1TB | The 2-3 inches of static appear at random intervals on the screen, I've also experienced the screen going completely blank from time to time. |
| Brian Pratt | 27" 3.06 Core2Duo 1TB | I installed the 10.6.2 update last night and I'm seeing the horizontal bar flickering this morning. So the 10.6.2 update didn't fix everything, at least. |
| Soaringoak | 27" 3.06 Core2Duo 1TB | dentical issue here... 2-3" bands flicker horizontally across screen randomly... happening less often is the complete blacking out, but it happens. |
| dicktwi | 27" 3.06 Core2Duo 1TB | I restarted once and I haven't seen the problem again. |
| SirR-G | 27" 3.06 Core2Duo 1TB | The first time it occurred was after running in Windows for a bit--the computer had gotten quite hot so I thought it may be a thermal issue. I noticed it almost immediately after rebooting into OS X at the gray Apple logo screen. |
| Stephen Stark | 27" 3.06 Core2Duo 1TB | There was a similar issue with my MacBook Pro, but there were two settings for the display—when you switched to the low power mode (I think) it cured it. I don't think there are similar setting changes that can be made to the iMac. |
