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:

Evidently, the last update to Snow Leopard, 10.6.3, has caused this problem. The solution is to switch back to 10.6.2.

How do I find out what is causing a random black screen on iMac?

Hello I get random black screen on a iMac and I haven't made any hardware changes. How can I find out what is causing this?
Thanks

You can do an SMC and PRAM reset. These won't hurt anything and 'might,' maybe help the screen issue. If it doesn't, then take it into an Apple store or AASP for their guidance and advance testing diagnostics.
SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Lines on MacBook Screen -- Help!

Hi! I have a late 2006 black MacBook 2,1 and whenever I boot up after a night of it being off, these lines appear on the screen. I can move the display back and forth and they'll move and some go away but I usually have to do that several times, lightly push one corner of the screen back and pull the other corner of the screen forward to get the to go away, sometimes i have to tap on the bezel around the screen and they'll go away, sometimes pushing down on the display will make then go away, and sometimes its just shear luck. Has anyone had this problem, heard of this problem, and more importantly know how to fix this problem? I'll take a couple of pictures when it happens. I know it's not the video card as the screen shots look normal. Thanks in advance for your help!! I know it has nothing to do with the opperating system either because it did this while running snow leopard, lion, and now mountain lion.

I have this same problem--mine was only on the right hand side of the page. It just came back from being fixed today (they replaced the main logic board). Unfortunately, it still has the problem. I'm working up the resolve to deal with this all over again.

When scrolling vertically there is an horizontal line which causes distorsion of the screen. I do not have noticed such concern on my iMac or on my macbook. What happen with the macpro ?

External Display Causing MacBook Screen Edge Darkening?

I recently purchased a Dell 2209WA monitor (rotated to portrait) and since using it I've noticed that my MacBook screen has a shadow down the right hand side.
Now I'm assuming that some part of this new monitor isn't suitably shielded and is affecting my MacBook screen.
I need to know whether this is causing any permanent damage or if it might be an issue with cables rather than the monitor itself?

I'm a total idiot. It was late, but I'm an idiot all the same.
Turns out the drop shadow from maximised applications crosses monitors...

Why is my MacBook Pro **crashing** changing to a blue screen with lines or distorted screen when I open logic or Ableton Live

Why is my MacBook Pro **crashing** changing to a blue screen with lines or distorted screen when I open logic or Ableton Live. Then I have to restart by long pressing the power button. Can somebody plz help me

What you describe sounds like a hardware issue. Unfortunately, you'll need to get that checked out by Apple. If you have an Apple Store near you, make an appointment with the Genius Bar and take the machine in for evaluation.

Single pixel white line across macbook pro retina screen

I have a Mid-2012 model of the Macbook Pro 15inch with Retina screen which is just out of 1 year warentee.
There has suddenly appeared a very thin white (pixelated) line across my screen - about 1/3 way down from the top.
Its constantly there, but more visible on a grey background.
I've contacted Mac about it and they say since its out of warentee they can't help!
Its literally 14months old... almost seems like the issue is perfectly timed to happen just out of warentee!
I'd be keen to hear if others have experienced similar problems with the retina screen or have found any solutions!

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.

Hi,
my macbook screen goes black at random points when I am using it. I know it is still running as music continues to play and I can vaguely make out the content of what is on the screen. Sometimes the screen will flicker between black and normal. Can I fix this?

Emily..
Could be the graphics card, run the Apple Hardware Test
If the hardware test doesn't reveal any problems, use Lion Recovery.

The screen resolution in 1920x1200 dropped on my MacBook Pro 17". Seems like I have not the same pixels. There are also vertical, thin lines on the screen. Makes the screen look milky. Anybody knows what's going on and how to fix it?

Take it to an Apple Store or other service provider for testing.

If it's a manufacturing defect, yes it would be covered.

My macbook pro keeps freezing with vertical lines on the screen

I have a 2010 macbook pro that has worked wonderfully until now. As of late it keeps freezing with vertical lines across the screen. To me this indicates a hardware problem, but I ran a diagnostic (restarted while holding D) and it didn't find any errors. It seems that it happens when I move or bump my macbook, leading me to think it may possibly be a disk problem, but I'm not sure how to check this. Anybody else ever have this problem or could suggest a fix for it?

You can try a pram reset, which might help with the display, but the bumoing thing is what concerns me.
PRAM reset:
Power down, power back up and hold the following keys before the start up chime.
option, command, P, R,(no commas) continue to hold these keys till you hear the start up chime 2 times then release.
Reboot see if this helps, the bumping part scares me.
Hope this helps

Blue vertical thin line at macbook pro screen

How to remove blue vertical thin line at macbook pro screen?

It's not likely that YOU can... it's MORE likely that you've a glitch with either your screen or your GPU. You need to take your machine into your local Apple Store or an AASP and have them take a look at your machine. The diagnosis and any estimate for repair will be free.
Be prepared, though, if you don't have the extended AppleCare Protection Plan, to pay for any required repairs.

I bought an MacBook Air 13 from Dubai last month. However I see smudge lines on the screen of the laptop which are prominent if the screen is black. Does the macbook air have international warranty ? Since I am in India right now. Can I get it fixed here

I don't know what service options are available in India but if this helps I do know that once you purchase your Apple product the warranty is valid anywhere in the world.
