Blue thin line

I have a 2007 20" iMac. Recently just reinstalled Lion and had a thin, blue, vertical line on the left side of the display appear. Wasn't there before upgrading from Snow Leopard. If you look closely, you can see it flickers. It's not too noticeable when the display is showing light colored images but when darker images are on the screen, the line is noticeable. What would make this happen and how would I go about fixing this without Apple's help?

What happens if you change the
display resolution? (Apple Menu > System
Preferences... > Displays > Display tab >
Resolutions) If the line stays in exactly the same
place despite the resolution change this points to an
LCD rather than graphics card issue.
mrtotes
thank you Adam for that hint. The line stays exactly in the same place. That means it is an LCD issue? That´s your opinion? Do you have any idea if it is possible to repair it, or is the only possibility to change the panel?
Thank you, Matse

Blue thin line on the lower left iMac G4 Flat Panel

Hi, since yesterday there is a blue thin line (0,039 inches (1 mm) thin; 35 inches (9 cm) long on the panel of my iMac G4 Flat Panel. It looks like drawing with a ruler, so straight and so fine.
The line is on the left lower corner in a vertical position. At first I thought these are dead pixels, but I checked this. No dead pixels. I have changed the desktop picture etc., but it`s all the same. I run the apple hardware-test cd - no problems found. Is there someone with any idea? Is it possible to have a damaged graphics- chip although the hardware-test is o.k.?
Does it make sense to open the iMac and look for dust and dirt on the motherboard?
Thank you for any help, Matse

Take it in for service. You may need to replace the 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.

Drawing and some layout help for a simple control: thin lines and application start

I am trying to create a new, simple control. The control should act as a grouping marker much like that found in the Mathematica notebook interface. It is designed to sit to the right of a node and draw a simple bracket. The look of the bracket changes depending on whether the node is logically marked open or closed.
After looking at some blogs and searching, I tried setting the snapToPixels to true in the container holding the marker control as well as the strokewidth but I am still finding that the bracket line is too thick. I am trying to draw a thin line. Also, I am unable to get the layout to work when the test application is first opened. One of the outer brackets is cut-off. I hardcoded some numbers into the skin just to get something to work.
Is there a better way to implement this control?
How can I get the fine line drawn as well as the layout correct at application start?

The test interfaces are already defined for you - the 3rd party session bean remote/local interfaces.
It is pretty trivial to create implementations of those interfaces to return the test data from your XML files.
There are a number of ways to handle the switching, if you have used the service locator pattern, then I would personally slot the logic in to the service locator, to either look up the 3rd party bean or return a POJO test implementation of the interface according to configuration.
Without the service locator, you are forced to do a little more work, you will have to implement your own test session beans to the same interfaces as the 3rd party session beans.
You can then either deploy them instead of the 3rd party beans or you can deploy both the test and the 3rd party beans under different JNDI names,and use ejb-ref tags and allow you to switch between test and real versions by changing the ejb-link value.
Hope this helps.

Laserjet 2605dn color printing problem, Blue/green line on page.

I have an HP color laserjet 2605dn that has started to print a faint,thin blue/green line from top to bottom about 3 inches in from the entire right edge of every page. I ran the cleaning cycle with no change. Any suggestions on how to correct this?

I have very similar problem on my 2600n which is printing 2 vertical green lines very close together about 1.5 inches from left edge. All toners are in supply override mode with black toner reading: Estimated Pages Remaining 0
Color cartridges contain toner with 329 pp remaining according to supply status page.
Is this problem likely to disappear when toner cartridge(s) are replaced?

Is there a way to create a heading with shading behind the text and thin lines above and below?

I'm working with InDesign CS6, Windows 7.
Is there a way, using paragraph rules, to create a heading with shading behind the text and thin lines above and below the text?
I'd like to create headings that look like these:
Thank you!

I have a document where I almost do such, but without the fill. I use a Head Style which Spans Columns for this instance; it allows the haeds to flow and fill the width.
Paragraph Rules above and below are turned on with plenty of offset.
I tweaked my setting to accomodate your need - It required only one instance, not above and below, and changing the stroke to a double stroke.
It may be necessary to create a custom stroke to modify the proportion of stroke vs fill. There is a difference of thin-thin and thick-thick, neither of which seemed perfect but might be dependent on the Character height.
Creating custom strokes is accomplished via the Strokes Panel.

Whats the easiest way to put a thin line around an image?

Can anyone tell me the easiest way to put a thin line around
an image? I'm also interested in the use of thin lines as part of
the graphic design on a page, how are they generated?
Thanks

Way too complicated. If you want to change the color or style
of the
border, you have to modify the image. With CSS you can
directly change
the line style in a much easier and faster way.

Print Apps won't print with C510a eStation. Prints thin line at top of page.

My C510a eStation printer will not print using the Print Apps. It just prints a thin line at top of page. Everything works fine until I print.
All other print functions work. It prints from computer via WiFi. It prints when I send an email to it. It copies via the Zeen. It just won't print using the Print Apps.
Does anyone else have this problem? What is the solution?
12/23/2010 3:00PM. I just got off the phone with an HP engineer. She said that the eStation is still in the TESTING phase and to call to report problems so they can improve the product. (I would have thought the product would have been fully tested before being released to the public!)
She had me reset the Zeen display by holding down the volume keys while powering up. This erased everything that had been done on the Zeen by me and resulted in no HOME screens, which will have to be set up by me. The only app at the bottom of the blank home page was Yahoo!. Even the printer app was missing. I had to move it from the app tray to the home page. Now, I have to spend hours, again, setting up the Zeen.
After the reset, the printer apps seem to work now. The Zeen will copy using the printer app. My computer still seems able to print and scan to/from the eStation.
The eStation C510a eStation printer and Zeen display are very exciting. However, they are not for someone not willing to spend the time to get it to work properly. If you have a cell phone, be prepared to use up a lot of minutes while on support.
The HP engineer said that it will soon have a new release of Android operating on the Zeen which will allow it to be faster.
This question was solved.

I have decided to return this printer to the store as it just has too many problems. HP has essentially told me they will not issue updates to solve the problems. I hate this, as I really loved the product.

I have Windows Vista and have tried everything! My Ipod Touch has Malfunctioned and cannot be recognized by Windows or Itunes! When I turn my Ipod on the white apple comes on and the 15 seconds or so after that a thin line comes on the screen above it.

A thin line appears above the logo then the loading sign pops up and then the whole thing freezes! I read somewhere to hold the home button and then plug in the usb will help it be recognized by Itunes or help to restore it! I tried that it didn't work.I tried uninstalling Itunes and then re-installing it. I have the newest version of Itunes and don't know what else is left to do? can someone please help?
Thank you for reading!

Try placing the iPod in recovery mode (I think that is what you were try to do) and then try to restore the iPod. For recovery mode see:

Hi jkjuarez2012,
Thank you for visiting Apple Support Communities.
It sounds like your iPod nano is only showing the Apple logo with a white background, and you've tried many good steps including resetting and restoring the device. I know I'd miss my music in this situation.
Make sure that you followed the steps in this article when restoring your iPod:
Restoring iPod to factory settings - Apple Support
If the issue continues after restoring, your iPod nano may need to be serviced. You can use this link to find out more about iPod service:
If the issue is still not resolved, please read this information on servicing your iPod.

Hello, I downloaded an ntfs systemfile from tuxera and used it to convert a usb stick so I could put more than the fat32 4gb on, my Imac froze a while after so I turned it off the on and now I have blue vertical lines on boot up and the a white screen with lots of tine blue symbols after, mouse pointer moves but thats about it.
Have used R and cmd to get a menu up but once I choose one of the four options my mouse is rendered useless and I cant get any further, have downloaded, to another usb stick recovery disk assisstant and am trying to use that in conjunction with the lion option on the previously mentioned screen, computer was responding really slowly and has now frozen on the terms of software license agreement (maybe the last hurdle!) can anyone pleeeeeease help!!!!!??????

It's likely that the boot drive is failing, or that there's some other hardware fault. Run the Apple Hardware Test.

Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.

Thin lines in pdf file displayed on mac

Hi,
I don't know if this is the right place to bring this up. So redirection elsewhere is appreciated!
I've noticed a problem with displaying certain pdf files on a mac. The files are 2D filled plots produced by the free scientific software Yorick (http://yorick.sourceforge.net/). It happens when I view it in Preview or Powerpoint on a mac. But not if I use a pdf viewer on a unix system. The yorick source code for a simple example is below. I can't find a way to attach files to this messages or I'd include the pdf's. Is there a way to do this?
Both png's are fine, and the pdf of the pli plot is fine. pli assumes uniform grid spacing, is fast, and must use different graphics primitives than plf, which does not assume uniform grids (i.e. you can have non-square elements). In this case both x and y grids really are uniform. The problem is with the pdf of the plf plot. Look at it in Preview, you should see some thin lines. Put it in powerpoint and the same. If you put some solid colored box in back of it, you'll see the color. So the lines are transparent or something.
David Munro, the creator of Yorick, suggests it's an issue with anti-aliasing.
Anyway, the problem isn't that severe in this example, but in others (which don't have simple source code) it's more annoying.
Either way, any advice on this, or the right people to report this to, is appreciated.
Cheers,
David

As I suspected, the problem is that the other viewers are not savvy enough to handle the "stitching problem".
What looks like a single image is really a WHOLE LOT of single squares. I took a snapshot of the Edit Object tool in Acrobat with all the objects selected. See <https://photos-3.dropbox.com/i/o/R6asqv64sEP1Tf7eIEBfNbFbMw0F7qKEaFwfnXQVKLo/1644474/12950 96400/0fa9181>.
As you can see from that, each square is a separate image that needs to be rendered and if the viewer doesn't understand how to proper stitch the pieces together then you will get empty pixels (which appears as white lines).
Either contact the author of the program that authored the document and see about getting that fixed (if it's not you) and/or contact the other viewers about improving their products.

I'm using a pc, (windows 8.1,) and I cannot get a thick and thin line with CS6. I want to draw, but I cannot get any linework like I should. I also use Sketchbook Pro, and ToonBoom, and I get wonderful linework. But not with Photoshop.

Thin lines in pdf file

Hi all!
I have a question. The same problem in Illustrator CS6 (but it appears from a few version of CS back).
I have document in an Illustrator. The document is generally for print, I don't using them to making website, so without using Slice tool.
I need have separation pdf so first I print the document to postrscript usind pdf ppd. Always the same settings:
1. General - only media size
2. Marks and Bleed - none (i mean all off)
3. Output - mode: Separations (host-based), and rest like is: emulsion: Up, Image: Positive, Printer Resolution: 71lpi/600dpi
4. Graphic - none
5. Color Managment - none
6. Advanced - none
7. Summary - none
After printing I have a separation, pdf file. Always appears vertical and horizontal thin white lines, like document was preparing for website and sliced.
Why this happend? Can I use some settings to avoid this situation? I tried a various setting but the lines always appears.. Help!

It always was in a bitmap.
