Flickering line on top of MacBook screen

I have a thin white flickering line (about 2" long) at the top of my MacBook screen -- in the area just to the right of the iSight, along the top of the screen, to be precise. It's a white flicker, so only visible when I dim the screen or there's a dark background, so there's no way of telling how long it's been there.
I have the 13.3" aluminium body MacBook (Oct. 2008 model), running Snow Leopard.
Does anyone have an idea what could be wrong? If I take it in, how long will it take to fix (if at all it can be fixed)?

It might be a defect in or damage to your Mac's display or video card.
An Apple-Authorised Service Provider has the required tools, test equipment, and technical data necessary to diagnose the actual cause of your "white flickering line."
If I take it in, how long will it take to fix (if at all it can be fixed)?
The AASP can answer that question after he tests at your Mac. You can ask about estimated times and costs for testing and repair when you are making an appointment for service.

What is the purpose of the black line on top of the screen in the latest version of iBooks for iPhone? It irritates me.

It has been around for a while. Like for the last 2-3 versions of the app.

Could you use the camera icon to post a screenshot here of what you are talking about?

Strange, flickering, lines on start-up / crippingly slow computer

For some weeks I've had strange horizontal flickering lines on my iMac's screen whenever I'm starting the computer. It looks almost as if the screen is suffering from interference from another source. However, once the log-in screen appears the screen is almost always normal and at worse suffers from a few spots of corruption that disappear once logged in. Beyond that the computer seemed to be getting a bit slower but, frankly, not so badly that it was a major issue and something I was putting down to age (it's over two years old now)
I did think this might be linked to the warranty extension issues (http://www.apple.com/support/imac/repairextensionprogram/) however when I called support last week I was advised to reboot in various ways which seemed to fix the issue.
Today, however, the flickering returned and the computer is crippingly slow and has become incredibly partial to the spinning beachball. I've tried rebooting a few times but this has not fixed the problem and I've started seeing other issues. For example the desktop icons are now scattered all over, my iPhoto library is empty (thought the images are still physically on the disk), it never remembers my wireless keyboard/mouse, etc.
Can anyone offer any advice? It would be greatly appreciated!
James.

The archive and install has solved the speed issue. The iMac is much speedier, but still seems lacking a little kick, but that might just be me. Unfortunately it's not restored a lot of the little issues (e.g. iPhoto's disappearing libraries) and I'm now discovering .Mac's backup isn't as good as it might be!
The flickering remains, however, so I'm guessing these were separate issues and I'll have to look into returning it for repair once I'm satisfied I've retrieved all my data and securely backed it up.
Thank-you everyone for your help and advice. It's the first time I've used this forum (and the first time I've had a problem since switching) and it's heartening to know it exists and, most importantly, works so well.
James.

I opened my brand new MacBook Pro the other day and noticed a straight green line from top to bottom near the center of the screen. What is it from and how do I get rid of it????

I am having a problem with my brand new MacBook Pro. After opening my laptop the other day I noticed a straight green line from top to bottom near the center of the screen. What is this from and how do I get rid of it? It is most annoying. Please Help!

"What is this from and how do I get rid of it?"
Such symptoms bode serious hardware issues and you shouldn't think about fixing it yourself when you are still in waranty. Get to an Apple Store, like the other poster suggests.

Macbook air, top of the screen flickers occasionally.

Hi, I have a 11-inch macbook air, mid-2012 according to my "About this Mac" and it works like a breeze except for a single issue. Every so often, completely unpredictably, the top of the screen will be flickering when I open the computer up. It goes away in a few minutes, but as my warranty runs out in a few months I figured I should get this checked out. Thanks for any and all help.

Absolutely YES go call Apple for a diagnostic / service call.
If the top portion of your monitor flickers for several mins. then your GPU/ Logic board is going bad. Possible the monitor cable or cable at junction with logic (i.e. cable connector fault at male/female at logic) board.
Take care of it immediately before your warranty expires.

Strange flickering lines across screen, opening Photobooth makes them go away?

Hi everyone,
I've been having a very strange problem with my 2011 Macbook Pro 15" for quite a long time now. It's basically flickering lines across the screen, and the screen 'folds' in on itself, squashing the display vertically and stacking them on top of each other. Sometimes it's terrible, sometimes it's bearable. Sometimes the screen goes completely black. It's super weird. Here's a photo I took my phone, as I screenshotting shows nothing out of the ordinary:
The really really weird thing is that when I open Photobooth, as in the apple webcam program, the problem completely goes away (until I quit it). I had hoped this was a software issue, so I backed up and formatted my hard drive and then installed a fresh copy of OS X - and the exact same thing happens! I barely made it through the system setup!
I beg, someone help me!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

My PC has blue screened twice in the past week so I force quit it it came back on a few times after that it is now grey screening with inch wide blue lines from top to bottom the apple logo is there and it is trying to boot up but nothing happening

My Mac has blue screened a couple of times this week it started to work a couple of times after that but now it is grey screening with inch wide blue lines from top to bottom the apple logo is also there it is trying to boot up again but won't. Not sure don't know anything about how to fix things but I suspect the fan has stopped working as I can't hear one. The problem I have I now live in Turkey and I am 1000 km from the nearest apple shop which is in Istanbul I believe and I now live in Didim, Altinkum I don't trust the everyday Turkish shop to take it to as they will tell you they know how to fix it but will probably make it worse, typical in Turkey. Please can someone help as we use it for our business and obviously I need it up and running ASAP I am using IPad and iPhone at moment but can't access my files which are on PC.

Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

Flickering intermittent lines on my display (Macbook Pro 15in Unibody mid-2009)

HI all,
My MacBook Pro 15" Unibody Mid 2009 is suddenly displaying strange artifacts across the display - flickering lines of color (seems like red is most common). When this happens if i flex the machine body i can usually get it to disappear. Running an external display works totally fine, even while lines are appearing on the built in display. Another strange symptom - while this is happening sometimes, when i am dragging a file in Finder, it refuses to release from 'dragging' - ie... the OS believes i still have the mouse button pressed down (whether using a trackpad or external mouse) and continues to do so until a restart or sometimes a force quit.
I suspect the display cable (which i have reseated to the connector), though the most effective quick fix while this is happening is pressure on the bottom, middle of the case (which of course worries me).
I should add, tho it seems strange and might be circumstantial - this all started after installing mountain lion (from snow leopard) and the artifacts dont seem to happen when i am running in boot camp.
Hoping this can be resolved by some minimal DIY fix...
Thanks in advance for any help!

Hi,
Not really a suggestion as such, but I have just installed a WD Scorpio Blue 500gb HDD myself. Unfortunately I've been having some issues with it and started a topic on this site to find an answer:

There is this black line that stretches about midway across the entire top of my screen... I read something about reseting my PRAM and I did that but it didn't remove the line... any insight on what is wrong with it and what needs to be done??
Thank you!

Is your Mac still under warranty? It sounds like a hardware failure.

How Do I add or remove any of the top 6 lines at the very top of my screen when I go online with Firefox

At the top of my screen when using Mozilla Foxfire, I have the following lines
Line ! starts with the word File
Line two is the tabs in use, i.e. Google Email and Mozilla Firefox
The next line down (#3( is a line that has an arrow to the left and shows the current web page on which I am working.
Line $ is "Most Visited" sites
Line 6 is ShopAtHome.com
What do we call these 6 lines and how do i add to them or delete them?

You can right click a toolbar to open the right-click context menu and set which toolbars to display.
*View > Toolbars
*Firefox > Options
You seem to be having the default toolbars like the Menu Bar (1) and the Tab Bar (2) and the Navigation Toolbar (3) and the Bookmarks Toolbar (4).<br />
You didn't mention what is on toolbar 5 and toolbar 6 (ShopAtHome) seems to be ad-ware or malware.

Do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.

Thin white line at top of ipod 80G classic screen

Would like to know if there is a way to get rid of this line, which is located across the top of the screen, in the area where the battery icon is located. The screen was fine then I downloaded the latest version of software for the 80G Classic and synced it. Next thing I knew I had this white line across the top of the screen. Is there a way to get rid of the line, or do I have to send the unit in and have Apple repair it? Only had the unit since December 2007.

Oh - you are good!

Out to TV causes lines on macbook screen

When I output to my TV using the Apple adapter, and as soon as I launch Front Row, my Macbook screen becomes nothing but lines, horizontally. The TV looks fine and I can watch it.
This also happens if I'm connected to my TV and use VLC.
After this happens the only way for e to get my macbook screen working again is to unplug the adapter.
I also noticed that once I get the screen back Front Row, even though it's been exited, still is using 99% of my processor.
So I guess what I'm saying is 'mirroring' my screen doesn't work.
Never had this problem before.
Thanks for any input.

I'd guess that you are experiencing the same problem detailed in this forum discussion:
http://discussions.info.apple.com/thread.jspa?threadID=2402283&tstart=0
Evidently, the last update to Snow Leopard, 10.6.3, has caused this problem. The solution is to switch back to 10.6.2.

I lost the address line at the top of my screen. how do i get it back?

The address line that is normally at the top of my screen is gone now. I'm not sure what I did but can someone show me how to configure my screen so the address line is at the top?

Are you talking about a web browser? the finder? If you are talking about a web broswer, and, specifically, Safari, you can edit the toolbar:
Then you can drag the address/search back into the toolbar:
If not.... then please add some details regarding what application.
Best regards,
