MacBook Pro :: Horizontal Line Across The Screen?

Sep 27, 2009

I have a new MacBook Pro (A1286) 2.66Ghz which is just over two weeks old. Whilst watching a video on YouTube a horizontal line appeared across the screen. I tried rebooting, however, the line was still present. I have tried switching between the 9400/9600 and the line is still visible.

The line is still there when I boot the laptop into Windows, does it look like I have a faulty GPU/logicboard on my brand new MacBook?

Here's a photo of the problem.

MacBook Pro :: Horizontal Line In Full Screen Mode?

Mar 30, 2012

A horizontal line appears in any application (iTunes, VLC, Quicktime) when I enter full screen mode. Out of nowhere it appeared about 2 weeks ago. Not sure how to get rid of this or how it came about?

OS X :: Dot Mark And Tiny Horizontal Line On Screen

Jul 6, 2010

I've just noticed two small marks in the lower right-hand corner of my iMac's screen: a tiny horizontal line to the right of a dot. I can see them when I restart the computer, but not when the wallpaper is on the screen. Clear Screen won't remove them, but they don't seem to be scratches either, partly because I can't feel them. Do you think they're dust specks or something like them tat somehow got behind the screen? I hope there's a safe way to remove them because I hate to see them.

Intel Mac :: Horizontal Gray Line Across Screen?

May 21, 2012

This evening, quite suddenly, a gray (or black, depending on what's on the screen) vertical line has appeared across my imac screen, about a quarter of the way up from the bottom.  Above that are some are three, much lighter lines (more like subtle variations or blocks of colour running across the screen). These appear on all windows I open.  I took a screen shot using grab and the very definite gray line doesn't appear.

MacBook Pro :: Horizontal Line In Display?

Jun 21, 2010

i've got a little problem with my Mac Book Pro.

I have a white line in the display where I also have my dock. So it's not always on the same Display. You can see a few pictures attached that show you that this line is some kind of weird. Windows that are always in the front like "About my Mac" are over this line and if I open all windows of one program I get three of those lines.

The lines are here since I updated my MacBook to the newest firmware.

MacBook Air ::5 Dead Pixels In The Center And The Horizontal Line Options

Nov 20, 2008

Anyone think this is a good deal? http://www.amazon.com/Apple-MacBook-MB003LL-Laptop-Processor/dp/B0006HU4DK/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1227225131&sr=8-1. I bought the Rev B, but had to return it because of 5 dead pixels in the center and the horizontal line issue. I am thinking of saving over $1,000 by getting the above. It is new/in box and from amazon. This is the best deal I have seen. It is even cheaper than the refurb models at apple.com.

MacBook Pro :: Unable To Know Horizontal Lines Across The Screen In MBP?

Oct 1, 2010

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?

MacBook :: Horizontal Bar Changes Color - Screen Looks Like Vibrating Rapidly

I'm getting this horizontal bar that changes colors and sometimes the whole screen image looks like it is vibrating rapidly up and down, I'm utterly at a loss. The model in question is an Early '09 with the 9400M IGP. It just randomly started last night. I've already had a video issue that got fixed, I think it was the GPU

MacBook Air :: Horizontal Marks On Screen From Keyboard Recess

Nov 8, 2008

Just what I needed - another thing to obsess about! On my screen, corresponding to where the bottom line of the keyboard recess is, I have a horizontal marks on my screen. Does anyone else have this? I've tried buffing with some iKlear and a soft cloth but it won't go away. I can't see it when the screen's on but it's bugging me now, as these things tend to do. With my old Powerbook I kept the plastic sheet in between the sceen and keyboard but assumed this was not necessary with the recessed keyboards. Now it seems its the edge of the recess, rather than the keys themselves, which is the problem.

MacBook Pro :: Vertical Line Reappears On Screen

MacBook Pro :: Line Across Screen Appeared While Browsing?

Mar 21, 2012

I see several posts about a line across the screen suddenly appearing. The only advice seems to be to get the computer replaced. I'd like to avoid this, obviously, as it leaves me without a computer and with a lot of work to do reinstalling software on a new one. I have not had any problems with the computer, then I installed the firmware update a few days ago (I think it was an update from February? -- something like an "IOE update"?) 

This morning, I closed the monitor and the fan kept running for minutes. I opened it up again and clicked "apple" > Sleep. And the display shut off. But the fan kept on blowing. Finally it shut off. But then it started back up. This happened several times. Finally I shut off the computer. Now, Sleep appears to work fine again. 

Then this evening I was browsing Reddit and when I clicked on a link, suddenly a row of pixels went out (see picture). I, at first, thought it was some weird pop up. But it persists through restart, and permission repair, and logging in with different users. I tried playing with new desktop backgrounds. This worked at first, then, for some reason, the computer wasn't accepting new desktop choices. Logging out, then back in fixed the problem. But that is sort of weird too. 

Are these issues related? Most important to me right now is this line across the screen. Incidentallly, at first the line was of varying shades of gray. Now it appears to be black.Is there a way that Apple can simply put my current hard drive into a new computer for me? This is a late 2011 macbook pro.

Mac :: Macbook Unibody Screen Shows Horizontal Coloured Bars?

Nov 23, 2009

Have had this macbook for just over a week, purchased off original owner who bought in Feb this year with Applecare warranty. Upgraded ram immediately to a G.Skill 4Gb kit. 4 days ago, computer randomly froze with horizontal coloured bar. Called Apple next day, the guy there told me that sometimes this happens, and that I should only be worried if this occurs ago. 4 days later, we are at this present scenario: In the last hour or so, has crashed 3 times. Programs running in common were iTunes and Safari.

MacBook Pro :: Black Line Under Screen - Broken Pixel?

Jun 17, 2010

I have had my MacBook Pro since November so it's still new. I take great care of it. This morning, I opened it up and noticed a small black line present under the screen. It has not been dropped, moved, beaten up, etc. It doesn't look like a broken pixel and all of the dead pixel fixers I have tried have not worked. Not sure what to do now. I live two hours away from the closest apple store and I cannot afford to send it out for fixing because I am an online student and need the computer daily.

MacBook Pro :: Odd Line Appear On Black Screen Display

Jul 8, 2010

I have a core i7 MBP with the high res display, and when the display is showing black, a horizontal green line appears on the screen. It is only visible when the screen is showing black or another very very dark color, and the line is not visible with the screen off. It isnt something on the screen, as rubbing it does not affect it at all. I cannot post a screenshot of it, because it does not appear in the screenshot (it does on my screen, because the line is there physically, but on other monitors it is not visible).

MacBook :: When I Move Screen Up Or Down A White Thin Line Flashes Across The Screen?

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.

OS X :: 10.6.1 Snow Leopard Hangs And Blue Horizontal Lines On Screen?

Nov 2, 2009

Over the past month I have encountered a number of bugs with Snow Leopard on my MacBook Pro (mid 2006). Ever once in a while, usually during high performance task (like watching flash or encoding with handbrake) the temperature of my cpu will spike to 85-90 degrees celsius and then the system freezes.

During this freeze, I can still move my mouse, but I am unable to click on anything on the dock or any program. Moving the mouse over the dock does not invoke the magnification either. I have to do a hard reset to fix the problem.

Also every once in a while, a long blue horizontal line will appear in on the screen. (sometimes their in iChat windows, sometimes safari, and sometimes the desktop as shown in the photo).

Mac Pro :: No Sound From Line Out And A Red Light In Optical Line Out

Aug 2, 2009

I've had this problem since Friday with my Mac Pro (March 2009) and haven't been able to solve it.

On Friday my speakers suddenly stopped working. After first having confirmed that the speakers were working with another source, I tried headphones both in frontal headphone slot and with the analog line out in the back, both without success. There's a red light in the optical audio out, indicating that it's on for some reason, although I have selected different audio out source. The internal speaker works just fine, only the normal audio out doesn't give me anything.

I found a thread in the MBP section similar to this problem, but solutions for MBP didn't work.

Mac Pro :: How Much DATA Do You Have On-line And How Full Is Your Total On-line Storage

Sep 6, 2009

Double poll here. There are two questions:
How much DATA do you have Oo-line?

This is data and not total capacity. This includes all your on-line data: music, images, video, the OS, all of it. It doesn't include back-up data even if it's on-line like Time Machine tho. Just active data.

And of the on-line storage devices used for that DATA totally, what % are they filled to?

For example if you had two 500 GB drives and about 400 GB of data you would answer:
"I have < 500 GB of DATA on-line." and,"My on-line storage is between 25% and 50% full.".

Mac Pro :: Problems Recording In Garage Band (line In, Line Out )

Jan 7, 2010

i'm having some issues recording in garage band which should hopefully be easy to clear up. i record an instrumental track into garage band through the line-in jack in the back. the track shows up in garage band just fine and plays, but i'm running into trouble recording while that track is playing. i plug my headphones in so i can try to hear the track while i am recording vocals, but i am unable to hear the track. i checked the inputs/outputs in system preferences and output is set to headphones, microphone is set to line in. so i'm not too sure what it could be.

Whenever I try to use Screen Sharing to control this one particular Mac Mini, and someone else is using the mini, and I pick "Connect to Virtual Display", I get dropped to a grey linen screen.  Like the login screen, but without a list of usernames or anything.  There it sits. Here is what I see in the console of the mac mini when I try and use a virtual display from the other machine:
