Black line Down Center of Screen

Alright guys see if you can figure this one out.
I have a MBP I have a black line directly down the center the the screen just under a quarter inch wide. It has been there for a while now but I was trying to fix it today. At times the line can get a bit smaller or larger and rarely it will go away...... I opened it up and unplugged the LVDS cable from the logic board and the entire lcd turned white but once i plugged it back in the lines retured. Not sure if this is an LCD problem or LVDS cable problem. I will add more detail if necessary but this is the start.

Do you see the line while the startup of the computer? Do you see the line when starting from CD/DVD?

  • I have a one inch diameter flickering line down center of screen.

    I have a one inch wide flickering line down the center of my screen. Can this be fixed at home? My computer is just 4 yrs old and I cannot afford to buy a new one. I love my mac.

    It's very likely a problem with the LCD.  You can decide if you want to fix it or not.  I wouldn't suggest trying to repair it yourself as it's challenging to replace an LCD on the iMac.
    Your best bet is to find a local authorized repair facility, call around and see if any provide onsite service. It probably will be at least several hundred dollars to fix.

  • Solid black line on HP tablet screen

    I just got this HP stream 7 5709. So far so good except there is a horizontal black line just across the screen. I first thought it is the screen protector, but now I begin to think it is in the display itself. Is this known?Attached the image here. Thanks

    any kind of lines on the screen that persist all the time are defective LCDs and will need a replacement. 

  • 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.

  • Ipad 2 front camera has a blurry black line down the middle

    Evening,
    My Ipad 2 front camera has a blurry black line down the middle, tried resetting but still there. back camera is fine.
    Any ideas ???

    Hello AndyPharris,
    It sounds like you're seeing an unexpected black line when you take photos with your rear camera. I would next backup the iPad to your iTunes library:
    iOS: How to back up and restore your content
    http://support.apple.com/kb/HT1766
    And restore it from your backup with this article as a new device to test the issue:
    Use iTunes to restore your iOS device to factory settings
    http://support.apple.com/kb/ht1414
    If it works, restore from your backup and verify it still works. If the issue persists when you restore as new, I would seek service for your device with this page:

  • Where'd that black line down the middle come from?

    I have a black line down the middle of each page of a template that is visible in the PDF Export. Since this is a magazine template, is it supposed to be there?
    Thx.
    Paul

    Okay, as long as it's okay that it shows up in the PDF export.
    Thx.

  • Hi, my Macbook Pro just shut down for no reason. Before, there were black lines all over the screen. Then it shut down and it started to make beeps (3). What can I do?!

    I was using my computer just as usual, I was on Microsoft Words and doing lectures on the Internet. Then, out of nowhere, the screen froze and black lines appeared all over the screen and the computer shut down. The screen was all black, but I think it was still open because my laptop was doing sounds, three beeps. When it beeps, the little light that shows you when your laptop is open is bright, so the beeps and the light are synchronized. AND I DON'T KNOW WHAT TO DO, help me!!!

    There is a hardware problem. Possibly bad RAM. Please make a Genius Appointment and take it in for service.

  • 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!

    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

  • Solution for black line in Ipod classic screen?

    Hello
    Last week my ipod fell on the floor and since then I have a black line in the middle of the screen. The ipod is phisically intact, no scratch, not broken. Only when I turn it on, I have a big black line in the middle. At the beginning it was small dots and now it s a big line
    Is there any solution? Change the screen? Or do I have to live with it?
    Thanks a lot in advance
    Vivile

    When you drop it, the impact knock off some connection in the Display circuitry, those SMT balls, so the missing connection cause the unwanted  lines.
    However if you are lucky, just try
    this iPod Hard Reset ( it wont delete anything on your iPod)
    Toggle the Hold switch ( make sure you dont see the red mark)
    Press Menu and center buttons simultaneously for about 10 secs till the Apple Logo comes ON then release the buttons.
    Select you language preferrence.
    See this Apple support article on the 5Rs
    http://www.apple.com/support/ipod/five_rs/classic/
    Good Luck!
    You can change your screen, if it is under warranty. (they replaced it with a refurbish iPod)
    OR if it is not under warranty, to can also get it replaced for a  fee at Apple shop
    or bring it to a 3rd Party iPod service vendor.

  • Random black lines in different application screens

    My MacBook Pro is displaying random black lines across the screen on various applications. They stay on the screen even if I scroll up and down, but don't go onto background applications or the desktop. Has anyone else had this issue?
    I'd be happy to email a screenshot.

    Uninstalled iTunes completely and found a older firmware for the iPod. Installed it. Then installed the iTunes 7 but did not have the iTunes update the iPod. Worked like a charm! No more black lines.

  • 1099 2010  Forms Print with heavy black line down the right hand side

    Greetings,
    When we print the 1099 2010 Mscellaneous Income form we have this heavy black line that goes down the right hand side of the margin.  We already applied all notes for 2010, including the latest one that had the margin correction published on 1/21/2011.
    Anyw

    Ours print that way, too.  The black line is in the 1099MISC_2010.bmp image that SAP provided in the note.  The image is used as the background for the forms.
