Intel Mac :: Screen Flickering For Fraction Of Second

Apr 11, 2012

My screen is continuously flickering ranging from quick lines flashing across various parts of the screen to the entire screen going black for a fraction of a second. This is now happening with more and more frequency. However, I do have a second monitor connected and the flickering is not happening on this screen (A Dell Screen). Is there a certain fix or should I contact Apple Care?

MacBook Pro :: Screen Flickering / The Screen Brightness Dims And Then Brightens Very Quickly?

Jun 15, 2009

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.

PowerPC :: Screen Resolution And Color Calibration / Grey Flickering Screen On Internal Monitor

Dec 5, 2007

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.

Model: PowerMac6,1
CPU-Type: PowerPC G4 (3.3)

and

the gfx chip is a GeforceMX4 with 32mb.

The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.

So 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.

MacBook :: How To Fix Screen Flickering

Apr 7, 2009

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.

MacBook Pro :: Screen Is Flickering A Lot Lately?

Apr 5, 2010

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?

MacBook Pro :: The Screen Is Flickering Intermittently?

Sep 12, 2010

Apologies 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).

MacBook Air :: Flickering Screen On Website ?

Nov 13, 2010

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.

PowerPC :: G3 IBook Screen Flickering?

Mar 15, 2007

...as the color green becomes dominant. The background on the browser is a faded greenish color, and the desktop image is degraded. Got some dandy streaks too! Searches say maybe logic board, but the guy I bought it from said it had a new logic board installed. Cables was a thought, but rotating iBook does not effect changes. I've shut it down for the moment, but am anxious to pinpoint the problem?

MacBook Pro :: Screen Flickering And Stay Mostly White

Jan 2, 2011

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!

PowerPC :: IBook G4 Screen Flickering With Movement

Sep 16, 2009

The screen on my iBook G4 is starting to very faintly flicker when there is the slightest movement on the laptop (e.g., typing with the laptop on my lap). My suspicion is that the display ribbon or something is frayed or loose. Any ideas on what might be causing it or how to determine it? How easy would it be to fix and for how much?
