Vertical blue scanning line won t quit

Vertical blue line continues to float across screen, does not stop! If scanning, I assume for security, one would think that once, twice and then go off?!
But no..it keeps going...no matter what.
It seems to hinder some sites!
Netflix it goes on continually across the movie! Keeps clicking on no matter what I do?!

You could have a hardware problem and you will not be able to fix a hardware problem. You may need to take it to an Apple Store and let an Apple Genius take a look at it. In the meantime, try resetting the iPad and see if that makes the line disappear.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

IPhone 5 backlight, blue scan line issue fix

[b]Found a fix for a double issue I was having, so thought I'd go ahead and post. Reason being that it took fixing one before the other resolved. I'd had an issue with the backlight on my iPhone 5 suddenly staying on after being used or even if a game notification came in or what not. Then I had that blue scan line that flows back and forth across the phone suddenly come on as well. Turning off/on the phone didn't help, nor did doing the off switch/home button reset thing.
What worked is going into Settings>General>Accessibility>Physical and Motor (down at the bottom) and then turning off the Switch Control.
I've had the blue scan line suddenly appearing issue before, and it seems the Switch Control comes on by itself because I've never gone in and turned it on. But it was the first time I'd had the backlight issue paired with the scan line issue.
Hope this helps some others out.[/b]

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

Vertical blue green lines on Tecra M display

I have blue-green vertical lines on my laptop monitor.
They only seem to be present when I have a white background (such as a web page).
The lines go away when I move my mouse over the screen and reappear when the cursor moves. I have no lines on video or pictures, just white backgrounds.
It's really annoying, please help.
I am using Win XP SP3.
I have a Nvidia geforce 6600 128M vid card.

Hey guys, I'm either thinking it's a VGA wire issue or the screen. I want to say VGA cable, bc in MS paint, when I filled the screen with different colors, the only colors that have lines through them are: White, Yellow, Red, and Beige. Orange did as well, but only slightly.
I tried moving around the screen, same result in all quadrants of the screen. This happens with similar colors in photo's and video. Typing a paper for my classes is really annoying because of these lines, arghghgh. . .

Blue render lines won't disappear

Hey guys,
The main issue is transitions, speed and filters refusing to render properly. They do 'render', however, once the footage is played back it is very pixelated at the points where i have added transitions or adjusted speed etc. I am working with .mov files. I have individually ticked all the boxes from the sequence menu and exported it to its final destination and it still looks the same.
Hope someone can help,
All the best,
Des

You can't really use MPEG 4 in Final Cut Pro without loads of hassle. It is not a supported editing format.
Where does the source material come from?
If it is from a camera, you would typically use the Log and transfer window to bring in your footage and transcode to ProRes or Apple Intermediate codec.
If the files came from elsewhere, you would use Compressor to convert them to a format such as those listed in the FCP Easy Setup menu.

Blue wavy lines during start up

Asking on behalf of a non-internet connected friend running a c 2001 Power Mac G4 (pre-MDD) which displays wavy blue horizontal lines scrolling down the screen during start up and for maybe 30 seconds afterwards. From then on it's fine. Is this an early sign of trouble and if so, graphics card or monitor?

What type of monitor are you using? CRT or LCD? If CRT(old tube,heavy type) can be affected by AC power line 60HZ frequency at startup of monitor if monitor is old.Other possibility is that it is not grounded well. Try changing the plug to a different AC outlet.If you can try another monitor and it does the same thing, it is most likely the Graphics Card .I doubt that if you have an LCD(Flat display) that it is the LCD. LCD's don't use AC voltages to cause those blue scanning lines. I could be wrong. Also see if all connectors are tight.

Vertical blue line won't go away ANYONE ELSE HAVE THIS ?

I have a vertical blue line on my MBP display, only one pixel thick but all the way top to bottom. Location-wise, in the finder menu the line runs between the 'e' and 'l' of the 'help' option - about 4" from the left of the screen.
The problem persists after a restart and stays there no matter which app I'm using. It's most noticable when the screen is displaying a darker image but when displaying a white/light/bright background (like the apple discussions) it's hardly noticable.
Seems to me like I have a vertical line of dead pixels and it needs to go back to apple for a replacement. HAS ANYONE ELSE EXPERIENCED THIS PROBLEM? and can anyone confirm that this means dead pixels, I've never experienced it before.
Thanks in advance for any replies.

Hello there. This problem is definitely a defect in the LCD display. Take it back to Apple for repair. I have had this happen with an old iBook.

IMac 21.5" boots to white screen with vertical blue lines/bars then locks up

iMac 21.5" (mid 2010) Intel Core i3 4GB RAM with Radeon HD 4670 boots to white screen with vertical blue lines/bars:
Then it locks up after a few minutes, at which point the screen changes to white with these blue symbol things all over the screen:
If boot to Safe Mode, it still has the white screen with blue lines/bars, but eventually loads the login screen and I can successfully login and get to the desktop, but even that has the bars/lines.
Eventually, after enough restarts or hard shutdowns it will boot normally with no video/display issues. I've run disk checks, did the SMC and PRAM resets, checked logs (that I know of), and have even taken it completely apart, cleaned it out, reseated everything, put it all back together, but no change. I've read a few other posts about similar issues (but not quite the same video issue as this) where people had the logic boars replaced or reinstalled OSX, but that didn't always fix it. Any ideas? Has anyone seen this issue before? Thank you.

Is this a dead disk?
Very well could be.
If you can not startup from the Hardware Test, in Safe Mode or from > OS X Recovery as discribed in the Support article's.
Dig out the original Install Disc set that came with the iMac and do one of the following.
1. Attempt to Repair the Hard Drive.
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
2. Run the Hardware Test from the second Install Disc.
1. Insert Disc 2 and Startup holding the D key.
2. Select the Extended Hardware Test.
Then if you still can not get anything going, you need to contact your Local Apple Store or AASP and make a Service appointment.

I repaired a cracked iphone 5c screen now I have a black screen with a vertical blue line on the left hand side of the screen. please help!!

Hi all,
Please help, I repaired an iphone 5c and have now tried two different lcd screens on it but all I get is a black screen or a black screen with a vertical blue line on the left hand side of the screen. I definitely have the cables connected properly etc and before I repaired it the phone had a cracked screen and there was a picture on it.
I have tried hard reset and nothing. I have tried connecting to iTunes but it asks me to confirm on the iPhone which I can't do as there is nothing on the display. I have tried randomly pressing all over the screen but it doesn't work. So I can't even try restoring it on iTunes.
Please help any advice will be appreciated! I successfully have repaired iphone 4's and iphone 5 before but this is the first iphone 5c.
Thanks.

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5s. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:

I purchased Macbook Pro i5 in March 2011. Now the screen has problem; one vertical blue line is in the screen (at the right side). I noticed this last week when I opened the MacBook, and now I am always seeing it. How to remove it?

I purchased Macbook Pro i5 in March 2011. Now the screen has problem; one vertical blue line is in the screen (at the right side). I noticed this last week when I opened the macbook and now I am always seening it. I am seeing the blue vertical line always in the screen. However, I am not seeing this line when I open Word, Excel, PowerPoint files (without pictures). But I am seeing this line always when I see movies, pictures, and all the files which have pictures. Please do let me know how can I remove this vertical blue line (blue tint) pernamentally from the screen.
Regards,
Ujjal

Backup your files to a external hard drive and disconnect.
Call Apple and make a warranty call, then take it to the nearest Apple Store etc.
You can run these things and it might clear your issue or give further informaiton
Perform a hardware check

Then see if resetting the SMC/PRAM resolve your issue

Permanent vertical blue line the screen and a red one has just popped up too. What does it mean and how can I get rid of them?

I have had a permanent vertical blue line on the right side of my imac screen for some time now. It does not affect the use of the computer. A red one has popped up on the right side of the screen and is not going away either.
Would you know why these are appearing and perhaps how to get rid of them please?
Thank you in advance

Best guess is that either your GPU or LCD is failing. You should take it to the nearest Apple Store or AASP for proper diagnostic. Once you know what the problem is you can decide wether or not it's worth repairing.

Out of the blue flickering and iCal won't quit

We bought our iMac 20" last January 2008 and it has worked perfectly. I have installed all updates. After the last update (and I really don't know if it is just coincidence...) iCal won't quit unless it is forced. All data is gone. It might also have something to do with the last time I synced my iPod...?
More troubling, the screen has started flickering... almost shutting down at points. However, it is not on a regular basis and seemingly out of the blue...?
Any help or advice would be greatly appreciated.

Wilrez,
Welcome to Apple Discussions.
Regarding the iCal issue, if you used Software Update for installing OS X 10.5.7, you may want to try reinstalling the update using the Mac OS X 10.5.7 Combo Update.
Let us know what happens with both problems after the reinstallation.
;~)

My macbookpro 15" screen has vertical blue lines

Hello,
I have a Macbook Pro 15" (mid 2010) 2.53GHz Interl Core i5 running OSX Lion 10.7.4.
Generally the computer and screen are in good condition and have had no damage.
The screen has Vertical blue lines and there is a tint of blue generally. The startup apple grey screen however is perfect, it is only when it enters the login screen that the lines appear. All the colours are off. Other than these lines the computer works perfectly
The computer was used yesterday (09 June 2012) without a problem for approx 1hour. It was then left for the day indoors on a desk out of direct sunlight. The computer was switched on later that evening and the problem started to appear
I have already tried to reset the PRAM and SMC with no affect.
I also read that it may be a cable problem, however as the startup screen works perfectly i question this.
Please can you help!
Thanks in advance,
Alex.

I suggest you take it to an Apple store genius bar or a repair facility for evaluation. This is most likely a hardware problem.
Ciao.
