Black and white lines up and down screen

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.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

This is a user-to-user forum. Apple does not respond to posts here. You can give Apple your feedback on the Feedback page:
http://www.apple.com/feedback
They don't respond directly there, either. And once you post something here, people will comment as they see fit, regardless of what you originally hoped for. That's just the way it is with a public forum.
Try Groove for iPad. People seem to think it's a great replacement to the previous music app.

Hortizontal black and white lines across web browser screen that appears and disappears but blocks usually 3/4 of web page, did not have with last version heard it might be my graphics card?

Since downloading Firefox 4, I will periodically get black and white horizontal lines that cover about 2/3 of the browser screen. There doesn't seem to be any trend to the website or areas it happens at, and will sometimes happen multiple times while scrolling through a large news article. The lines stay fixed to a certain area. The only way to get them to go away is to refresh the screen or if the page is big enough scroll to an area not affected and then scroll back. I've heard from someone that it might be my graphics card. My computer's a hand-me-down but not terribly old so it could be that the card is just old or bad, any other ideas?

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

How can I prevent my screen getting covered with black and white lines while working on the internet which only happens with firefox and only go when I 'go back' or go down a page?

It happens as I surf - horizontal black and white lines particularly when I scroll down and only goes if I can go to a new page or go back a page. It is driving me crazy and only happens with firefox. I have disabled all plug ins but it still happens.

Horizontal black and white lines on screen

I accidentally dropped my iPhone on my macbook track pad. It was about a 6" drop, nothing huge. But when the phone hit the laptop, the macbook screen immediately went to horizontal black and white lines. It reminded me of static on a tv. The lines lasted for about 30 seconds and then the laptop shut down and restarted itself.
Should I be checking the hard drive or anything?

How's it been running since then? Possibly you hit it hard enough to put a voltage transient through the machine.
Hopefully the logic board wasn't damaged but do what Oglethorpe says and have Apple run an ASD on it.

My new iPhone 5 has black and white lines on the screen. It's not been damaged. I've tried turning it off but this does not solve the problem? Please help.

By far the most common problem hardware-wise seems to be scuffs on the aluminium. Yours is the first report of a faulty screen I've seen.
If you use the same Apple ID on both devices it'll sync whatever you want it to - music/apps/photos/messages/etc.
I've just switched from a Galaxy S3 to iPhone 5 (having already owned an iPad for a while) so I'm in a similar position!

When I scroll up or down on my screen, black and grey lines run across my screen and next to the scroll bar. How do it fix it?

it is possible that zoom maybe enabled i think double taping with three fingers should disable it.
or you can go into settings>general> assessability> zoom and turn it off.
hope this helps

HT4061 I have black and white lines on my screen what is up?

My screen is displaying black and white lines. How do I fix it?

Try a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. The phone will reboot. If that doesn't fix it, then make an appointment at the Genius Bar as it sounds like you screen has given up.

Iphone 4s less than year old att, want work, blue and white lines black screen

I have a iphone 4s with ATT, not even a year old. I dropped phone and now the screen is black with blue and white lines. I have attempted to reset the phone with no success. Is this a matter I can resolve with ATT or do I have to drive to genuis bar to get resolved?

It's probable that the iPhone has suffered hardware damage, and I don't believe an AT&T Store can do anything for you on such issues. You'll need to take or send your iPhone to Apple and pay their out-of-warranty service charge to get the iPhone replaced.
Regards.

Macbook display shows black and white lines when fullscreen

If i leave my Macbook on for a while without shutting down and then I view a photo or movie (in player or safari) fullscreen the screen shows just black and white lines. Sort of like bad tv reception. It has happened a few times and a reboot has fixed it but it comes back. Any ideas anyone?
Thanks

I have a similar problem. Not sure you're on here (since the post is really old) but did you manage to work it out? How?
My thread:
https://discussions.apple.com/message/19007548#19007548
My Imac froze earlier today as I was dragging an image from safari into indesig and when it froze the weirdest pattern overlaid the screen. It looked just like the opacity pattern from photoshop with grey and white squares. I turned the computer off using the power button and unplugged everything.
Now when I try to start it these weird lines appear on my start up screen (see link)...
http://meijerladdaruppgrejer.wordpress.com/2012/07/24/oops/
as you can see the apple and the wheel appears as normal...
... then it moves to a normal looking white screen (perhaps a bit greener than usual) and around 30 seconds later freezes at the blue screen.
I've tried the cmd + alt + p + r several times but it won't help.
If i press alt during start up I can see and choose my hard drive but just end up at the blue screen again.
Can I try starting it up in safe mode or something?

Scrolling with mouse on pages create black and white lines,

When scrolling with mouse, periodically the whole screen turns into black and white lines. Sometimes whole page, sometimes just pictures/side ads. If you continue to scroll it does go away but then you need to scroll back to where the lines started, its hard to explain, i have taken 1 photo of the problem but will take more photos as i can, i really enjoy how Firefox runs on my computer, it has always been the best browser for my needs. I did recently buy a new desktop, but it did it then also, so i removed it and tried running explorer and Google and i just don't like them, so i am hoping we can get this fixed.

No matter what website I am on all of a sudden the page will be covered in black and white lines and I can't see any of the page. What is happening and how do I fix it? It has only started since I loaded Firefox 4 this week.

I am very frustrated because I keep having my pages become covered completely in black and white lines. It has even happened on this page when I tried to use the drop down arrow by 'this happened'. I can sometimes read the page if I click over the area I want to read but this is not common. This has only been happening since I downloaded Firefox 4. I thought this would be a better version but now I am not so sure.

I do not want to download another virus program.. I do not believe it is a virus. I am running the full version of Norton 360 and it is doing a daily scan. I have Windows 7, 64 bit OS.
This is very irritating !! If I wanted Yahoo I would ask for it !

Try resetting your phone, hold the home and sleep/wake button down until the apple symbol comes up, then release. If that doesnt work, you may have damaged your phone and need to take it to an apple genius bar.

Why does my photoshop keep giving black and white lines when I use my lasso tool?

why does my photoshop keep giving black and white lines when I use my lasso tool? It has never done this before last night. It filles the Whole lasso seleted box with (what it almost looks like) black and white caution lines. then when I go to zoom out, my zoom option starts to mess up where you cant click and move your mouse to zoom in/out with ease but where you have to click to zoom out (many times).
Can ANYONE help me?

I am using CS5, WIndows 7, I am not sure how to tell if my drivers are up to, and I am more than happy to screen shot it.
