This happens every time when I turn on my computer or restart. Otherwise all other computing and display are fine once I get passed the log in screen.

There's some known documented issues concerning the Nvidia graphics chip in the particular model of macbook pro I have.
Basically when turning on the machine, the screen is filled with black & white horizontal strips like a piano keyboard, but thats it - it doesn't actually boot up fully at all, you cannot hear the hard drive running !
Would the hard drive have anything to do with this ?
I explained this to apple telephone support & they informed of the article

& stated that the symptoms were linked.
On taking the mac to an apple store they ran a special 'firmware' boot up 'test' using an instore ipod to determine if it was a faulty Nvidia chip, so as to prove to Nvidia, the company funding the repairs whether it is that to blame.
Because the machine didn't even boot up & complete the 'test' they couldn't say whether it was the graphics chip - so 'no free repair' under extended warranty & the final answer was as usual ' buy a new logic board' that will cure it !
When I start up my macbook pro white and black lines appear for the startup screen in bunches. After that the screen is black but the keyboard is lit up and you can still hear the sounds of turning up the volume and music can still play.

View 5 Replies View RelatedMy Late '11 15inch Macbook Pro went bonanas today. When it starts up there all these black horizontal lines running across the screen jiggering jabbering everywhere and I see three apple logos (due to GPU glitch I am guessing) after loading everything goes white and my laptop heats up and battery dies within like half an hour. I was bummed but then like after restarting a bunch of times and recharging my laptop it starting up normal again! I was super happy, but then it experienced the same crash next time the battery died. So, this has been going on and off;

So I had a recently purchased 17" BTO with the 7200RPM drive that worked great, but with one issue - the display would have horizontal scan lines and black out occasionally. So I called up Apple and eventually managed to get a cross-ship set up(they let me hold on to my current unit, charge my credit card and send me a second brand new 17" unit as a replacement,and then refund me for the second 17" after I send back the defective unit).
Anyway, the replacement unit looks great, but with one issue - there's a very small light dent on the bottom panel(maybe about the size of a dime). I was annoyed but don't think this is worth having to exchange, since I could probably just unscrew the panel and pop it back into place.
However, what really got to me was the fact that my replacement unit was slightly louder than my original - my original is so silent that I can't even tell it's on. However, with my replacement unit, I can hear the hard drive spinning, which is slightly annoying.
Anyway, I proceeded to restore from a time machine backup and test my replacement unit when I noticed that it would occasionally get the hard drive click + beep + freeze issue that many others who have the 7200 RPM drive seem to be facing. It's extremely annoying, and more importantly I miss the complete silence of my older unit.
My question is, while I'm still in possession of both units(which both have the exact same specs, same 7200 RPM drive, etc.), should I simply just open both up and take the silent(good) hard drive from my old unit and put it into my new one?
The click+beep freeze issue is really pissing me off, and my old unit didn't suffer from it - it's just this replacement one(doesn't make any sense).Anyway, would notice if I switched the hard drive? Would I get screwed somehow? Do they keep track of the hard drive serials or something?
I really don't want to go through the pain of sending this back, especially considering that a LOT of people are suffering from this issue, and I don't want to end up with another defective drive. I'm sick and tired of games and just want a computer that WORKS.
I recently got my laptop back after the logic board was replaced and now black lines with white text keep appearing on the screen. When this happens I cannot do anything except hold the power button in to reset.

I have a 2007 MacBookPro. shortly after installing Lion 10.7.3 and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc.When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts. Reconnecting all cables back together, I came across, what I think is the camera cable. Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem. This morning It decided to boot up. I was able to copy my essential files onto an external drive.

I've had my iMac for over 2 years now. Last Thursday, I left it on for more than 3 hours and it started having black and white verticals lines appearing on the bottom and top part of my desktop and the cursor. Yesterday, when I checked it again, it was still there! What can I do to fix it, WITHOUT going to a Apple store?

Simply using my Imac for watching tv on the web, Hulu, and left to help my wife get groceries in the house. My wife checked her email and closed Safari.
I came back in roughly 10 minutes from when she shut down Safari to see a black screen with white pinstriping, and the mac being totally unresponsive. Shut down and rebooted, sent off the report to Apple, and am now here with seemingly no problems.
Needless to say, as a photographer this computer is just about as important as my camera. Should I be worried? discovered the thread to this issue, which appears to be quite extensive.

So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.
Mini Mac will not boot, startup screen consists of horizontal black and white bars.

I was excited to see if the horizontal lines would be corrected but to my dismay they are still there. Looks like it's going back to Apple.

I've had my macbook air 13" 256GB for four days now, I had it shipped to me in Canada because I wanted the ram to be changed to 8GB. When I'm scrolling around on the internet I see a horizontal line appear in the lower half of my screen, it disappears quickly so I haven't been able to get a screen shot. I have apple care, should I take my laptop in? Is this normal? I've been very careful with my laptop, I haven't dropped it or anything (I even have it in the Tech21 Impact snap case).

I have a MBP purchased in late 2006 so it's fairly old.
Lately I've been having really random lock ups and freezing maybe once every week or so. Sometimes when I hard reset it, there's a few horizontal lines across the screen, usually just on the background. It'll go away if I restart it again.
I used the onboard disk checker and no problems are detected. Is this a sign that the hardware will fail soon?
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.

Starting this morning, when I boot up my MBP, it seems fine through boot up, but when it reaches my desktop, the taskbar, dock and desktop icons never show up and instead I have horizontal lines across the screen. I tried booting up from my external hard drive, but I have the same issue. I can see the mouse and move it around and the desktop wallpaper shows up sometimes, but nothing else shows up. When I boot up in safe mode however, everything looks fine. I have not upgraded anything anything recently, either hardware or software.

my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could.

After 1 month there are small thin horizontal lines appear on my macbook pro screen. i never drop or bang or what so ever.
View 1 Replies View RelatedI have a 2 month old rMBP Mid 2014 and i am experiencing horizontal lines in the middle and bottom of the screen. For example, If i was browsing a site and then close the window you can still see parts of the website in the middle of the screen. I took the laptop in for the technicians to have a look and they a blaming it on the software,claiming that Gfxcardstatus is causing the problem. The problem still persists even with gfxcardstatus turned off. Does Gfxcardstatus do this? Is it the Lcd or gpu failure? Take a look at the photos ....

On my screen when looking at whites or light blues, I seem to notice these faint horizontal lines only on certain places on my screen. For example, on the posting page, the light blue has very lite horizontal white marks on it, only in certain places. (I tried smacking it...(not to hard...I couldn't have damaged it right
View 5 Replies View RelatedI received my new 15" PB a few days ago and I can notice faint horizontal lines on every other row of pixels. I didn't notice this on the model before this or even the new iBooks, but working with photos, graphics, and video is aggravating with these lines.I called Apple Support and they seem to think this is a limited issue. I'm sending it in to get repaired or to get a new screen put on it...stinks when it's 4 days old and I'm already getting it "repaired"
View 24 Replies View RelatedI have had my iMac for two years now and when I first got it not a week later the video went out, well at that time it was still under warranty so I figured, what the heck I'll go get it fixed. Waited a month got it fixed got it back, works perfectly. It's now 2 years later and everytime I try to run anything intense, i.e. World of Warcraft, or any game for that matter (also happens when the majority of the screen is dark) these horizontal lines appear, the darker the screen is the more intense the lines but once I open a lighter/white document the lines disappear.
If I use the screen saver (flurry) is starts to do it also and you can clearly see RGB pixels all across the screen. I have been searching the internet for a good six months hoping someone will have the same problem, but that does not seem to be the case. If anyone has any idea what is going on, I have tried to reset the SMU and the PRAM but to no avail, I have also heard the swollen capacitors issue and have checked the board for swollen caps but all are flat. As far as specs go it is an iMac G5 2Ghz (Summer 2005).
i got my imac this june, so i'm not sure what generation that makes it. (somone let me know plz) anyway just today i noticed I have some horizontal lines going across it. very faint and hard to notice, but i'm anal and i noticed them. My first instinct was to find out how to degauss this monitor.
