White line/spots?

Hello, I have a macbook 7,1 and am still under waranty by about a month. Lately, there seems to have appeared a white line followed by a spot in the center of my screen. At first I thought it was just dirty and cleaned my screen, but it didn't go away. I've had this line for a while and it is very annoying when watching movies on my macbook. My question is, what are these lines? Is this problem common? Are they dead pixels? Can they be fixed? Is it covered by the Mac warranty and can I go to an apple store and have it fixed? Any help is appreciated. Thanks in advance.

Hi Try a Reboot press power button & menu button hold both down until you see Apple Logo You will not lose any data. This could be a Hardware fault if it's still no better take to Apple Store. Cheers Brian

White lines around PNGs when exported to PDF

I am having the problem that imported images frequently have white bars around the outside of the image when the document is exported as a PDF. Looking at the two images currently affected I notice they are both PNG images. I fixed the image that was just rectangular in shape by just turning it into a JPEG as I did not require the use of transparency, but the second object is a different matter and I require the use of PNGs transparency. These lines are not present when in indesign normally.
The line is only noticable in one spot where a black rectangle meets the black background (only the top of the rectangle is visible against the black as one side is covered and the other side is out of the crop area) so I am not certain if this is the only spot it is occuring.
The line is not even a straight white line!
I have had this problem before with lines appearing around objects which should not be there, as well as objects not appearing as they do in inDesign, any advice for fixing this?

Ok guys I don't know what was wrong with my old TIFF image, but I swapped it out for a TIFF image which had a gradient fading from black to transparent as opposed to a straight black box and now the line is not there *shrug* it seems quite weird to me since I made sure the image was correct by cutting off the top segmant of the image where the trouble was.... but I dunno....
The exact same image in illustrator or photoshop showed up fine.. so I cannot understand what the problem was
EDIT: GAK!! its back on a new image I just put into the document same problem except it is on all sides of the black rectangle... *shakes fist* bah I will put another bloody gradient around the stupid thing....which by the way worked and the gradient was placed on the bottom layer so I dont see how it could be the image? I think this is proving that the problem is with acrobat (or saving from indesign) not the image...
NOTE: I would rather not post the files for various reasons

Good workflow to avoid white lines and discolored boxes with transperancy?

I'm somewhat new to Illustrator. I have designs in illustrator CS4 that contain objects with drop shadows that are on top of gradient backgrounds. When I save out the artwork as a PDF file I see random faint white lines and discolored boxes around the objects with the drop shadows. When I print proofs of the file on my HP3500 color laser printer I see the white lines and discolored boxes as well. I'm afraid the the lines will show up in production when I send off to the printer. Here's what I'm doing. Any suggestions would be appreciated.
(Document Raster Effects Settings: Resolution-High 300ppi/Background: Transperant/Options: preserve spot colors, add 12.7mm around object)
1. Save file as PDF from Illustrator CS4
2. PDF Settings
a. PDF Preset: PDF /xa:2001
b. Advanced Overprint and Transperancy flatener options: Preset-High Resolution
When viewed and printed from Adobe Acrobat 9 Pro there are white stiching lines that are visible.
Do I need to worry about these? Or will they go away when sent to a better printer?
Thanks for the help.

Try "Press Quality" Acrobat 5 compatable setting for "live" transparency. You can also try PDF/X-4 2008 which maintains live transparency and, in CS4, maintain Acrobat 5 compatability. PDF-X1 is a setting that "flattens" transparency which may limit your output options, depending on final output device. Double check your raster settings and make sure it is set for 300ppi/2400dpi and not 72ppi/300dpi. As suggested by Wade, your printer may not be a Postscript Level 3 output device with a RIP. So, the driver may not be screening the artwork properly and the stitching shows up in output. You may benefit from taking the file to a prepress shop and have them output a "contract" proof. If the stitching shows up in the contract proof, then the PDF setup may be the problem or the original file itself.

Annoying little white line on letterbox matte.

When I scrub throught footage or if I hit play little white lines apear on the edges of the letterbox png. How can I stop this?
* It doesn't appear on the final result
* It stops me from seeing exactly how it will look

How can I stop if from doing this?

Thankyou. This was a bit stupidly simple, something I should have spotted, but thanks!
For those who keep mentioning why I use png.
I downloaded "FILMDOGPRO'S" letter boxing templates and they are all in PNG.

Help! I've got a white line going across the top to my I pod

I have a 80gb classic ipod and I've got a white line going across the top. it is extreamly annoying and nothing can fix it not even restoring my ipod what can i do

That sounds possibly like there are dead pixels on the screen. I am not too sure about what type of screen is in the new iPods, but on my Sony PSP there are white spots in places, which I was informed were dead pixels. Sony mentions it in their literature regarding the PSP.
You should be able to take it back to your Apple store, and they should be able to take a look at it for you.

Odd white line, about a cm in length

I have a 2/3 year old Powerbook G4 15" in my lap at the moment and there are a few odd little white spots. One is just a little blob on the screen, and the other is a white line about a cm in length.
What is this, and is it covered by my Apple Care?

well, it could be stuck pixels. for example, if the subpixel is stuck to be on, it will be bright. or white. if this is the case, then it would need some repair. and you should let a tech look at it to determine if it is covered or not.
or you can try a PRAM reset. which helps with video issues.

What is this white line under my preview window?

I accidentally hit T while editing and suddenly there were 2 preview windows in my preview window. I hit T again and it went back to 1 but now there's a white line under my preview screen. What is it? And did it do something to my image? How do I remove it? And what does T do in adobe premiere? And what were those 2 preview images in my preview window?
Here's a picture:

Please help me, I've worked too hard on this project to have it be ruined now.

Dont think you have to worry about the white line. I think the program monitor is not updating correctly. Resizing the window should fix that.
T is for Trimwindow.

White Lines Across Powerpoint files converted to PDF

I have a number of PDF files that were created from Microsoft Powerpoint presentations on a Windows PC. The Preview inspector says they were created with Acrobat Distiller 8.2.2. Until recently, these PDFs looked 100% correct when viewed in Preview or Safari. Now, though, they have horizontal white lines across the pages. There are 6 white lines on each page, evenly spaced, each about 1 pixel in height. They stay at 1 pixel in height even when I zoom in/out on the document. At some zoom levels (100% being one of them), the area above and below some lines will become misaligned. When viewed with Adobe Reader 9, the lines are not there but the misalignment is (though it is not exactly the same as in Preview). Unfortunately, I can't say when this started happening other than it was fine in September (2010) and isn't this afternoon (Nov 22, 2010). It happens on a coworker's Macbook Pro as well as my iMac so it is not something unique to my Mac.
Anyone else seeing this? Any ideas as to how to fix it?

Hi, I am having this problem also on my iMac. Some of the images have the lines and some of them don't. When the PDFs are printed, the lines don't show. My problem is that these PDFs will be linked to on a website for the clients to print, and they will seem them with the lines. They are pretty unsightly, and my boss has put this into my lap to figure out, since I am the designer. Did you ever find an answer for this? I don't know where else to turn, since this company is insisting on using Pages, rather than something like InDesign.

Cursor arrow gone from solid black to having white lines go through it and trackpad is not working properly in mail and adobe acrobat - anyone know how this could have happened and how to solve it?

Can anyone help me? Concerned that I may have some kind of malware. My cursor arrow and trackpad are behaving strangely, The cursor used to be a solid black arrow but now seems to have horizontal white lines running through it. The trackpad does not function normally either. For example, when I use my trackpad to scroll up and down in mail it sometimes works and sometimes does not. In adobe acrobat it sometimes does not work. In facebook, the cursor does not line up behind the menu keys as it should.
Any one know how this might have happened and how I can stop it?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

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.

When I turn on my iPod Touch 5th generation, half of the screen has vertical white lines and it is irresponsive to the touch... is there anyway this can be fixed because this is my third time in the last 4 months I have had problems with Apple.

The screen looks completely normal besides the vertical white lines on the right hand side of the screen, as the "slide to unlock" is lighting up and the time and date are changing, but the screen is unresponsive. After several problems with Apple in the last few months (and two defective iPods including this one and one iPhone), I really don't want to go through the whole process of bringing it in or getting a new one entirely. It would greatly help if someone knows a solution, even if that would require completely resetting the iPod to factory settings, as I have had is synced to iTunes before. It would be greatly appreciated if someone could help. Thanks.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem. Seems like a bad digitizer or connection or logic board.

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 !
