MacBook Pro :: Screen Flickering Magenta / White And Pixelated Image

Jun 12, 2010

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.

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!

MacBook Pro :: Samsung XL2370 Monitor To Hook Onto MBP 15 - Image Is Pixelated And Blurry Green

I just bought a Samsung XL2370 monitor to hook onto my MBP 15".

Problem: the image is pixelated and blurry green. I can slightly see the background though. Screen works fine on a Windows pc. Before I hooked up a 19" on my MBP and that also worked.

I tried the menu but no luck. And when I choose the auto adjustment a message appears 'not available'.

MacBook Pro :: Some Blue / Magenta Light Leaking From Bottom Of Screen - Is It Normal?

May 12, 2010

My 2010 13" Pro seems to have some blue/magenta light leaking from the bottom of the screen. This is only visible with the brightness turned up and against a black background (i.e. when watching a letterbox movie). It's quite different from the "typical" white light leak that I've witnessed on other lcds. Would this be "normal"?

Also - and this may seem like nit-picking - but my caps lock key feels a bit flimsier than the rest of the keys. Again - is this "normal"?

MacBook Pro :: 17 Inch Screen Is Pixelated?

Jun 19, 2012

I was using my computer and it was just fine. I closed it carefully (as always) and left for a few minutes. When I came back and opened it up, the screen was completely pixelated. I turned it on and off and read several forums and tried cleaning the drives and nothing is working at all. As I've been working on it parts of the pixelation of bright colors have begun flashing a little bit. Not a lot but a little. Black doesn't seem affected by the pixelation but you can see lines in the white areas. Also when images are fading in and out, they don't become pixelated until they are at their brightest. When they are fading in and out they appear fine.The graphics card in my computer is a Nividia GeForce GT 330M. SO I'm guessing from this that the graphics card is damaged or whatever. I can't afford to have apple repair it for $400 and the nearest apple store to me is two hours away.

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.

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).

PowerPC :: Powerbook G4 Screen Red Pixelated / Screen Going Out?

Jul 8, 2008

I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new.

That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts.
