Black horizontal lines on start up and doesn't load GUI

So here it goes
My 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; I don't know whats going on but it seems fixable I just want to know how.

Probably by replacing the logic board. I suggest that you take the MBP to an Apple store genius bar for a FREE evaluation . Then you will be in a position to make an informed decision.
Ciao.

one of first versions of macbook air with black horizontal lines on bottom one third of screen and vertical line also one third of left side of screen

Hi
I've recently notice I have a thin black line in my screen.. I went to Apple store and was told it’s a hardware problem (400$+ to fix as no warranty).
This is the second time I’m having hardware screen issues with a Macbook Air (last time it was 3 months after I bought it, and it was replaced with this one)
Looks like the Macbook Air screens are very problematic! Anyone experience something like that?
Thanks,

Black horizontal lines when printing

The printer prints all black horizontal lines on several pages wehn starting to print or copy. totally black and unreadable. After several pages, it gets better, but still is not a totally clean print. I have reveiwed all your suggetsions. The scanning works fine, only printing is a problem. I have cleaned everything, replaced print cartridges, but nothing works. Someone supggested there is a controlling cartridge that my need to be replaced. I cannot find any information on this anywhere. Please help, thank you, Pam

Can you scan a print showing the defect and post it here? It would help to understand the nature of the lines and at what space they repeat.

HP Officejet Pro 8500 Leaves a black horizontal line while copying

HP Officejet Pro 8500 Leaves a black horizontal line while copying . It can print fine, but whenever we make copies (black, or color) we get a straight horizontal line running across the page. I'ts a perfect line, no streaks, nothing i do can fix it, any ideas?

Are you putting the copies through the auto feeder? If so, you might want to clean the roller and the glass that it would roller over. I also clean the white bar that is on the bottom of the cover.
I have the same issue but it is white line when I am scanning.

Thin black horizontal lines on 24" iMac screen/transparent dock icons

I have a 24" 3.06 GHz iMac (purchased in August 2008) and noticed after about a half hour of running basic programs (Mail, iTunes, Firefox) I start to get horizontal lines near the top and bottom of my screen. Then if I watch a full screen video I can see my dock icons look almost transparent through the video. I took my iMac into the Apple store last month and told them about it and they kept it for 3 days and ran their "tests" and stressed the computer out to get it to do it for them but they couldn't replicate the problem. They suggested that it might be my cordless phone is too close to the screen and the frequency of the cordless phone could be causing the problem but I tried moving the phone and it still does it. When the display is off for hours and I turn it back on the lines are not there, but once I have it on for a half hour they come back and don't go away until I power off or sleep the display. I've attached a few pics of what I'm experiencing. Thank you very much.

Since the Apple Store folks could not replicate the problem, you may want to consider a cause that is part of your particular environment.
For example, if you use a power strip (surge suppressor), what else is connected to the same power strip? Is it possible that you may have too many power-hungry devices connected to the same single wall outlet, and the iMac is not getting sufficient power? Or maybe it's some electrical interference with another device on the same circuit? As a test, try disconnecting everything else, and see if the problem recurs, or connect the iMac directly to a wall outlet by itself to see if the problem recurs.
Try moving the iMac to a different location in your home and running it to see if the problem recurs.

Black horizontal line

Last week I bought a 2013 macbook air and already in the last few days I've had a couple of occasions where I saw a a few black horizontal lines across the screen. Last time it happend for a couple of seconds when the laptop was coming back up from sleep. Is this normal? Or should I take it back to get it swapped?

What kind of machine? Could try smc and pram reset. But if it's the display or video card failing it won't do any good. If it's a mac pro blow out the dust and reseat the video card.

Aperture printing with black horizontal lines on Epson RX580

Hi all,
I've recently converted to a Mac and Aperture after decades on PCs. I just printed my first pictures with Aperture on my old Epson RX580, and they have thin but distinct black horizontal lines. About 3-4 evenly spaced lines on an 8x10.
It's possible that my printer is just dying. I did the nozzle test and the alignment test and cleaned the nozzles a bunch of times. But the lines are still there.
I'll try to print from another computer (to confirm that it's the printer), but is anyone familiar with this? Could it be something in the Aperture settings or in the way it talks to the printer?
Thank you.

Black horizontal line ipad mini Safari

New iPad mini appears to be having problems already. While using Safari in some websites, a fairly thin black horizontal line will appear typically in the middle of the page. It usually gravitates towards the spot where you try to read. Thin enough to kind of underline text for easier reading but big enough to be a nuisance. Is this a feature for easier reading in Safari or a bug.
Please help,

Michele,
I know this was mostly answered, but I am there with you. It's a very frustrating problem and you are not alone.
Merging the keyboard and splitting it again, as well as hard closing Safari, seemd to fix it, if only temporarily.
Slightly lifting the split keyboard from the bottom seems to completely solve this SEVERELY annoying and temper tantrum inducing problem. It has taken me more time than I'd like to admit to fix this, and I have my doubts that it will work permanently as well.
But anything that MIGHT work is better than dealing with this issue.
It may seem minor to some, but for a lot of us, it is very distracting and annoying.
I keep hoping with each and every update that it's fixed, and am disappointed each and every update.

I'm trying to record only part of my screen using my Quicktime 10.0, but once I press record in the "Screen recording" feature it automatically starts recording and doesn't give me the option to choose what part of the screen to capture. What gives?

QuickTime version 10 can only record the entire screen.
10.1, 10.2 and 10.3 offer part of the screen recording.

My mac mail will not search mail anymore and doesn't load attachments anymore

Does anyone know why this would be happening?
My mac mail will not search mail anymore and doesn't load attachments most of the time. When I enter some text in the search box no results come up and I know there are messages that contain the phrase that I've entered.
Also about 3 weeks ago attachments only get loaded about 1/4 of the way - if that. So I have to log onto my web based mail program from the host and retrieve attachements or check the messgae with my iphone.
Please - does anyone know how to fix this?

I figureed out that spotlight was turned off via terminal - I shut it off to unmount a disk (which didn't work anyways)
sudo mdutil -a -i on
that's the termianl command to turn spotlight back on. As far as my attachments not fully loading in mac mail on my iMac that still baffles me.

Installed Firefox on Windows 7 but the menu and icons bar is full of little horizontal lines over the icons and menu bar..

I installed Firefox 21 on a new Windows 7 OS. The menu bar and the icon bar at the top of the windows is full of little horizontal lines. Sometimes there are more lines and sometime less lines. It makes the icons and the menu items almost impossible to see. So far it's only the Firefox screen that does this. The other programs I installed so far doesn't do this.
Any ideas?

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Pav. dv3888nr horizontal line on DVD image and other glitchy things

Whenever I play DVDs I have problems. Lately, its been a horizontal line or split across the DVD image. I also get all kinds of burps and hiccups, and picture separation from sound that is usually solved by tapping in the mousepad. (Weird!) This gizmo is still under warranty but I'm out of the country for a few more weeks.

Yes, Apple is working on it. The information I gathered from AppleCare is that there is a "capture" procedure in US for those who don't like the lines on their machine.
At this time, as there is not such a procedure in Europ, my decision is to return mine. The only way to return your PB is to call the AppleStore from which you bought it and ask them for a refund (if you are within the 7 or 14 days depending on the Country you bought it from) or an exchange .
Applecare will only accept a repair, by the local Apple Certified center, but AppleCare is country specific which means that an applecare bought in Europ will not work elsewhere. Personnally, I declined the repair, because we all know that the defect has not been identified yet by Apple US, so that you can imagine what the local repair center could do !!!
PS : I just identified the EXACT same line issue at my working place on a Sony LCD screen connected to a G5 DP 2Ghz. Strangely enough, the LCD has also colour set up problems. Moreover the same configuration at home (same SONY screen, G5 DP 1,8 Ghz) has no lining problem. This is the definitive proof to me that every lined screen are defective, even if hundred of them have been recently released.
