The screen on my Macbook Air just recently started to periodically display flickering lines. They are multicolored and stretch across the entire screen. Hardware test was ok, and console not reported any issues. MBA is "late 2010". Warranty ended January!

I have flickering lines on my macbook pro , screenshot doesn't show them up, and I don't know how they got there.
Panicking a little as this laptop is fairly new and expensive.
I was sitting with my MacBook Pro, when out of no where, purple vertical lines began flickering on the screen. I tried getting them to stop, then eventually just shut down my laptop. When I went to power it up again, it first popped up with the white apple screen and chime, then a gray screen dropped down with the message "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button.".
I tried the Power button option first, but the computer does not come back on. When I press the Power button again, it does the same thing all over again. I do not know where the "Restart button" is, so I haven tried that. I have also tried pulling the battery and restarting, restarting in safe mode by holding the shift key at start up, and trying control-r and control-s functions. None of which worked.

My brother's ibook (14", 1.33 Ghz, 1.25 GB RAM, 10.3.9) recently developed a problem: when he would open it, the screen would show fuzzy lines for a few seconds before "stabilizing." He tried to live with it, but it got progressively worse. Now, the lines never disappear, and the screen flickers as well.

i have checked/repaired disk permissions.
not sure what could be causing this problem.
I just purchased the Macbook Air rev 2 120gb HD model. I it has the problems with the lines on the screen. It flickers on the one test image from the forums, but does not appear to flicker during normal usage. Also, it has a sort of CPU buzzing comming from the left side of the keyboard. It gets worse then I move the trackpad.
I was thinking of calling support on this, but I don't want to end up getting the same screen with the same problems. I was wondering if anyone has gotten any of this fixed. Is there some way that I can direct support so that they put in the correct model of screen.
It's been happening for a few weeks and I really need to know if it's something bad or not because I can't afford a new laptop.Â

I have a new 17" uMBP that I've owned for just a few days. I noticed yesterday that while I watching a video that i had strange green/red lines (horizontal) appear across the screen and flash/flicker. I freaked out and closed the lid, putting the unit into sleep, and opened it again and it all stopped. Today, I was using it again as usual, on firefox/etc. when it started happening again. Horizontal lines across the screen, the entire display flickering and screwing up and finally going black. I don't know what's going on, but I know this definitely isn't supposed to happen. I took a screenshot during the flickering/lines/etc but the screenshot came out perfectly fine unfortunately. I'll try and get it on camera next time.
I have all software updates installed. I tried resetting PRAM. The flickering I'm talking about isn't minor, it's actually absolutely horrendous and the computer is completely unusable when it's going on. It ultimately leads to a black screen. Anyway, this is all on the 9400, and I have no idea what's going on but I definitely know this isn't supposed to happen. UPDATE: I booted into Windows via bootcamp and it STILL happens. I also connected it to an external display(which works perfect), which leads me to believe that it's 100% a hardware issue. I'm taking it back to the apple store, enough said. This is my first Mac and I can say I'm definitely not happy to be having such issues with a $2500 machine.
Lines on calendars are not showing. Nor are the input box outlines on websites.
View 3 Replies View RelatedMy Macbook pro's display has started playing up. Having green flickering lines which come and go randomly, especially on images with a lot of black. Right now, the lines just disappeared as soon as I connected to mains, to start recharging the laptop. I'm using OS X 10.7.4 with NVIDIA GeForce 9400M.

My MacBook Pro's screen has been going black recently, sometimes is pops back up and sometimes I have to shut down and reboot. But while the screen is dark the computer seems to be functioning (music still playing, sounds from touching keys randomly in the dark) I recently upgraded to Yosemite - coincidence or is my 6-year old Macbook just getting on in years?

I've got a friend with a 17" PowerBook G4 that's suddenly started displaying a vertical strip of black lines about 2" wide. Any idea what's causing the problem? I've seen plenty of pictures of PowerBooks with pixel-wide strips of a single color, but none that show black lines. Something else to note is that the problem area is displaying a shadow of the previous window that was there (ghosting).
He's tried all the usual, from rebooting to rubbing the problem area to pressing the metal strip above the keyboard to try and reseat the ribbon cable.
My trusty imac has started displaying pixelated thin horizontal lines?
View 5 Replies View RelatedHas 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.

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..

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 9 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.

View 3 Replies View RelatedAlmost 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!
So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

On my home wifi the screen flickers on my MBP. It looks like the top bar flashes irratically in the middle of the screen. There are no other issues and works fine otherwise. Just annoying that I can read or see anything...I will attach a video later. Right after I turn off the WiFi it goes back to normal. And of course my warranty expired, so I'm trying to find a solution to this before I spend $350 more on fixing this $2000 machine.Â

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.Â

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.
Recently I connected my macbook air (bought it in 2011, now on Version 10.9.3) with a Panasonic TV (TX-32LM70F) via Thunderbolt to HDMI adapter. After I disconnected the external device, the macbook air's screen still worked normal, but when i restarted it, it was only flickering grey. Â
I found out that it actually boots normally and i can use it with an external monitor (in fact I am using it right now), but that the built-in macbook screen simply doesn't work anymore. Â
I tried to restart while connected and while disconnected to an external screen, I have reset the SMC Controller, I have reset the PRAM Controller, but it hasn't changed. Â
This is actually the second time something like this happenend (it was another external device i connected it to), and last time, about a few weeks ago, it just worked again after a few days for no reason, all i did was wait until all energy was gone from the battery and the reload it. So might it be a battery problem? Or is it some controller i don't know? It was the same phenomenon two times: connect to external monitor - disconnect - built-in screen still works - restart - built in screen only flickers grey - macbook still boots and works fine with the very external monitor that might have caused the problem.
