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..
View 1 RepliesWhenever i tilt the screen forward or back wards like the whole screen flickers i dont know how to explain it but like as if you were turning a tv off that shuttering moment? well that similar thing happens but when i move my screen. The computer works fine and everything but its just that i have never dropped it or nothing so can anyone tell me why this is happening and what i should do.

MacBook, Mac OS X (10.6.8)
Almost every time I would move my Macbook Pro (I generally use it as a desktop, so move it very rarely) my screen would come on white and not show anything for an hour or so, (except a flicker or bleed of color here and there) when the image would suddenly flicker on back to normal. Now, it just stays mostly white, with lots of lines going up and down - the bit of 'color' in the lines does seem to match where windows should be on screen, but very generally, and it doesn't update in real-time, it 'refreshes' every so often. I attached a photo so you can see what I'm talking about.
I had my logic board replaced about a year ago now because of a faulty Nvidia 8600 chip (have a Santa Rosa MBP). I'm currently using an external monitor - which last time was exactly what I did when the chip started dying out and external display worked just fine then, despite the fact that the GPU couldn't drive the internal display anymore, so that's not a clear indicator that the GPU is fine. When I first started having this problem, I brought it to the Apple Store, and they ran the test on the GPU and said it was fine... but that was months back, so I don't know?
I'm thinking (hoping) this is a display cable issue and not a GPU issue. Also, if it was the display cables at fault, how much would it cost to replace the display cables? (internal LCD -seems- to work fine, backlight, etc., I think it's the connection..) Also, as a side-note, since my internal LCD is no longer working, how can I boot into Windows XP (Boot Camp) on an external monitor? It seems not to 'plug and play' at all, unfortunately, and I obviously can't get to the display settings if I can't see anything on the LCD!
I'm having a problem on my mbp screen, although it happened only once just an hour ago. The screen goes flickering magenta and white and some pixelated image. I needed to force shutdown using the power button because it seems to stalled. After restarting, it went to normal. I dunno if it has anything to do with the gfxstatus utility that I've installed the night before. I know it might be the nvidia graphic card itself but I just don't have a clue right now. My MBP is just 8 days old and my 1 to 1 exchange has expired since it covers the 1st 7 days only.
My MBP spec:
MacBook Pro 17" AG, i5 2.53 Ghz, 4gb RAM, 500gb Hitachi HD, 512mb nVidia GT330M video card, Mac OSX 10.6.3, with everything updated. Tthe attached pic is not showing the exact image since the screen was flickering etc and I'm just using a camera photo. I just noticed while I'm just surfing this forum + facebook, my temperature is at 67-70 degree celcius, which is high (normal around 38-45). I look at Activity Monitor and found that Kernel Task is using up to 80% of CPU. I have a feeling that this is not normal, and it had not happened before.
Has anyone noticed a very slight flicker on their new MBPs? I have a new 13" and, every so often, the screen brightness dims and then brightens very quickly (happens in less than a second).The option for auto-adjusting the screen brightness is off so it's not that particular function.It's most noticeable on all-white backgrounds both on AC and battery power. Hard drive access doesn't seem to coincide with the dimming.
View 17 Replies View RelatedI 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?
I've had the new macbook air just two days now. Turned it on this morning, used it for like 5 minutes and the screen just started flickering, and the whole machine just froze on me! Had to do a system reset, but I'm a little concerned after spending over a grand on this macbook! Has anyone else experienced this? I'm actually thinking about returning the machine..

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.

everytime when i turn on my macbook, the top part of the screen flickers.. I don't recall seeing that happen when i first got my macbook. anyone else have the same issue? something i should worry?
View 3 Replies View RelatedSo my 20" 2.4 Imac crashed on me twice tonight. A box popped up telling me to hold down the restart button for several seconds to restat. The second time I did this it just sits with a white screen and give three loud beeps over and over. Is there a fix for this? Is it my ram? I'm at a loss.

View 21 Replies View RelatedSo I have noticed a few times already, that the screen on my white macbook flickers to change the brightness level. It can do this while the computer is plugged in and charging, or if it's off the charger. It is definitely noticeable as it causes me to just watch what the screen is doing.
View 13 Replies View RelatedI'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.
View 2 Replies View RelatedI 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?

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.
Recently my Macbook Pro 2008 is having following problem. First there are wavy blurry lines appears on screen and then it freezes for a while and then it restarts its own. On restarts it gives following message.

there are two things that the macbook is doing to me. one is that sometimes when i move the screen up or down (the hinge is rather stiff) a white (thin) line flashes across the screen. but recently, while randomly browsing through the internet, the screen almost... i guess faded to a gray screen, but like gradually, and not like a kernel error, like the display just faded away. happened twice in a row, did a battery pull and now wont do it again.
View 6 Replies View RelatedI 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.

My mac screen is frozen with white fuzzy lines going across the screen. I shut it off and turn it back on but it still remains white fish lines on the start up screen. I've tried revolting it, it works sometimes but now its stuck at the starting screen. I have been at this for 2 hours to try and fix it but nothing has changed about the screen.

Does your screen flicker too, when you watch this pattern ?

My white Macbook, the one i'm currently typing on; the screen keeps flickering. 've uploaded a video taken from my cell phone of the screen flickering. I love my white macbook but the screen keeps flickering until I keep adjusting the angle of the screen. Some days the screen flickering is minimal and I'll adjust the screen easily with minimal screen flickering. Other days i'll be adjusting for a few minutes until I can get it at an angle where the screen doesn't flicker.Here is the link of the screen flickering: [URL]I've noticed there is less/to no flickering at all the closer I adjust the screen downward, i.e., the closer it is towards the macbook itself being closed.
As for the Macbook itself, it was purchased in December 2006 and have had AppleCare since. In June of 2007 I took it in to Apple since I noticed the screen flickering very minimally only when the screensaver came on. I was then told a small soda spill was on the logic board and AppleCare would not cover it, though I was still covered regarding all cosmetic repairs, aside from that soda spill. It hasn't been till the past 2 months the screen flickers heavily and I'm just sitting at my desk adjusting the screen until there is no flickering so I can get my work started. I was considering selling my Macbook for anyone that wouldn't mind the screen flickering but i've upgraded this Macbook with a 500 GB hard drive and before attempting to sell it i'd rather fix the problem myself.
Everyone, I'm all ears. I'd love to fix this problem. If it means completely voiding my AppleCare warranty and opening up my Macbook, so be it. the warranty expires in 6 months anyway.
I did a quick search of the forums, and so I know there are previous threads about this. But my screen is flickering a lot lately and so I plan on either sending it to Apple, Driving 3 hours to Dallas since it's the closest Apple store, or taking it to an authorized repair place here in town. I just have a few questions for anyone that has either had this problem before or maybe just has dealt with repair issues before.1. Should I wipe my Hdd?2. Which of the three options would be the better bet?3. Anyone know if they would just fix it or if they would replace it?

View 10 Replies View RelatedApologies if this has been posted before, but rather than trawling through the thousands of threads, and before hitting the Genius Bar.... thought I would run this by the experienced MBP owners first.Got my first MBP (crossed over from PC back in April), and within the last couple of weeks, noticed that the screen is flickering intermittently.
Wondered if it's a glitch stemming from the switch from Graphics card as/when needed, or if it's an indication of something more serious and warrants taking it in to the Genius Bar... (don't want to part with it for days unnecessarily).
I went on a website only to noticed the black lines & columns on the page, especially at the bottom, gives off a noticeable flicker on my 13'' MBA.
Obviously with the issues of MBA screens, I'd like to check with you if the same thing occurs on yours? I'm finding it very worrisome that my screen could be faulty.

Leave it for a 10 secs and the black lines flicker quite noticeably on mine ( I have click to flash installed & you tube 5 extensions.
I have a Macbook Air that is about 2 years old. Recently, the backlight started to go off randomly, it always lasts for less than a second and then is back to normal.
