Occasional red line down middle left of screen

I got my computer around April of this past spring (2014, however the model is mid 2012) and just recently there has been a bright red vertical line running down the left side near the middle. It only happens occasionally and it stays there for about 10 minutes and then goes away. I realize it doesn't effect it THAT much but it's annoying and I recently bought it, if you pay $1,200 for a computer I would expect this not to happen. Why might this be happening and what can be done to fix it?
Note: neither the computer nor its screen have experienced any trauma.

A new Mac is in warranty for 1 year from the date of purchase.
You can take the computer to the Apple store to have it checked out.

Red line down screen

My monitor has a red line down the middle of the screen. Does anyone know why this is happening? Sometimes, depending on the background color, the line is green (on lighter backgrounds), otherwise it is red.

I have the EXACT same problem and also bought my iMac in Dec 2011. Thankfully I have AppleCare. I called support; had to back up the machine and take it in to an Apple Store for a new monitor and a new video card. They didn't seem to be all THAT horrified at the problem so perhaps it was a bad batch of monitors in that run of manufacturing.
Anyway, I'm using my MacBook for now and they expect the iMac to be fixed ready in 3-5 days.

Purple Line Down Middle Of Screen After Update

I just bought a brand new ipad mini.
Everything was fine, then i get a message asking if I want to update to the newest ios version.
I say ok and it downloads and does the update.
Then I notice there's a purple line going down the middle of the screen?
Is this a software issue or a hardware issue?
Is this related to the update?
Should I take it to an apple store and try and get a replacement or is it a simple fix?

Try this - 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 - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Black line down middle of copies

We have a HP 6480 all in one that prints fine but when we make copies it prints a black line down th middle of the copy? I have cleaned the glass and rollers outside and in. what else can I do??

Hi ChrisCanon,
The lines on copies that you are experiencing is a result of the scan glass being dirty or scratched. The scan glass that the printer uses when scanning from the ADF is located to the left of the larger glass area (platen) when you open the cover. It is the smaller glass strip on the left hand side of the unit.
Spray some glass cleaner on a paper towel and then clean the smaller glass area. Once cleaned, try scanning from the ADF again.

Photos have a line down middle.

Hi, I have a canon rebel t3i and my pictures are coming out with a line down the middle. One side is lighter than the other. I thought it was just the screen, but when I print my pictures the line appears with half of the photo being darker/lighter. Do I need a new lens?Please help.

Are you using flash? If so, is it the one on the camera, or is it a Speedlite in the hot shoe?
If the flash is not sync-ing correctly with the shutter, you may get that, as the shutter is really just a rectangular opening that travels horizontally in front of the sensor. If the opening passes part of the picture before the flash fires then half the picture will not get light from the flash.
I once had that happen when my Speedlite flash had slid loose in the shoe so it was not talking well with the camera.

Removing and re-installing iTunes won't do any good as it does not pertain to the iPod in any way. If none of the 5 R's of troubleshooting helped, we can definitely say that it is a hardware issue with the iPod's LCD display.

Vertical red line on my iMac computer screen.

I have a vertical red line on my 2009 21.5 inch all-in-one iMac. I can see it on the desktop and it's also there regardless of what window or application I'm running. I'm not sure what caused it but I sure would like to know if I can get rid of it. Thanks!

Having read some related discussions after I posted (my apologies), it appears there's no solution but that I need a new display. Can I get a ballpark estimate on the cost please? BTW, the line goes only about 3/4 of the distance from the bottom of the screen to the top of the screen.

Vertical black lines down middle of page

Hi folks,
I have an LaserJet 4250n that's putting vertical light black smudges/lines down the center of my pages. It's all the way down, but it gets lighter at certain points and picks back up again. I've tried replacing the toner cartridge and cleaning the rollers, to no avail.
Any ideas?
Thanks!
James

Hi James,
I am a printer technician for HP in Australia and a full time employee. I look after many printers including this one.
Lines down the page can be caused by a few things - depending on what the line looks like.
If it is a smudged dirty streaky mark continously down the page, you migh have a dirty fuser - it may have been picking up toner and it has built up and then put it back down on the paper.
A thin defined black line might be a scratched drum or developer - the laser might be refracting and drawing the defect onto the drum.
Blank or white lines could be something stopping the toner from getting to the paper - transfer roller under the toner might have something stuck on it.
A repeated mark or defect could also be a dirty fuser - glue or wax from envelopes and labels could do this.
Try swapping the toner with another to test - borrow one if you can.
Run 3 or 4 cleaning pages - in the menu, configure device, print quality menu, create/process cleaning page.
Remove the fuser - back door comes off, little blue clips, pull it. out - rotate using the green knob and you might be able to gently remove something stuck in it.
If you can get to another 4250 or 4350 you could borrow the fuser and find out.
For this machine, I find worn out fusers and dirty printers are most commonly showing these symptoms. Next common is low quality after market cartridges.
Hope I can help you here

White line now appearing down middle of display screen today

My iMac of 2006 Tiger OS has had problems with thin, coloured vertical lines appearing on the screen since December '12. At that time I got a lot of responses and an indication that the problem was the ATiRadeon X1600 GPU. The thin vertical lines have increased a bit and I'm now up to 3 on the right and 1 on the left which haven't been any problem. However, just now a white line appeared almost down the middle of the display screen? It blanks out the places where it actually runs. It's very thin but noticible. I have taken a screen shot and viewed it in Preview. None of the lines show there? Any further ideas for a fix? I have a Seagate HDD attached so all is being backed up. Thanks! Illa

Lot's of folks had those lines after 1 or 2 years. There was even an Extended Warranty Program for a time, but it lapsed 2 or 3 years ago.
Personally I'd say that we have both faired very well over the years, my Early 17" Core Duo didn't start getting lines until towards the end of it's 6th year.

I have a red line on the left hand side of my Macbook Pro screen

I have a Macbook pro 15" 2012 model with a red/turquoise line which appeared the day before yesterday on the right hand side of my screen....i have plugged in a monitor to see if it appeared on that monitor too and it hasnt? What could be causing this and is it expensive? Please can anyone help? I have tried all the tests on different apple forums resettting the memory and the board and nothing has worked....it did disappear but has come back permanently now. I've only had the Mac for over 16 months so as you can tell not impressed!! I have a macbook air late 2010/2011 and never had any problems apart from the magsafe adapter!!! Any help would be very much appreciated?

First question is do you have Applecare? If so, just take it in and let them fix it.

White Line Down Middle of iPod Classic Screen

I have recently noticed a thin white vertical line on the right side of my iPod classic screen. It doesn't affect the iPod's function at the moment but I'm worried that it is signaling a potential technicial problem. I have tried all the initial troubleshooting steps suggested but am leery about uninstalling and reinstalling iTunes.
