Vertical lines through certain colors on screen

I have vertical color lines through my screen. It's a all in one desktop. Never dropped or damaged. I just noticed it the last couple of weeks. I would like it to be nice again. Any suggestions? I have pictures.

Hi,
You could try reinstalling your PC's graphics driver. Open HP's Recovery Manager, select hardware diver reinstallation, locate the graphics driver and follow prompts.
But it does appear to be a hardware problem.
You may have to contact HP Support.

  • IMac 17" has vertical lines of multi colors

    Just bought a iMac 17" and it has vertical lines of multi colors. What are the causes, how can I troubleshoot the source and what is the most cost effective way to fix?

    Since the last 17" iMac was discontinued in 2007, it's unlikely that it's still under warranty, unless you managed to get Applecare with it.
    I had the same problem. The local Mac repair place, Dino computers in Pasadena, said that what it needs is a replacement display, but that alone costs $500, plus installation, so it isn't really worth it to fix.
    But I found a website call realmacmods.com, which offers a kit just for this purpose. Not for the layperson however. You can get a kit for about $50 and supply your own 17inch display, or you can buy a display plus adapter board for $150. I talked to Dino and they said they could install it for me for about $120. I decided to get some Mac tools and try it myself. The vendor recommends you have some laptop repair experience, which I don't have, but I have opened up desktop computers before, and that helped. Anyway, it worked. And, you get a higher resolution display: 1900 x 1200, formerly 1440 x 900. It looks great. But again, not for the layperson.

  • What does it mean when there pink vertical lines on the start up screen?

    What does it mean when there are pink vertical lines on the start up screen on an IMac ?

    It means you have a hardware problem. That could be the screen itself or the graphics system, GPU.

  • Vertical lines through screen

    I have 2 small gray vertical lines down my iphone6 screen and the screen and buttons in that area won't respond. Has anyone else had this problem and is there an easy fix?

    Hello elaforce,
    It seems your display has vertical lines and will not respond. Based on the information you have provided, it appears your iPhone needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

  • IMac 10.4.11 Because permanent vertical lines have appeared on my screen, I need to get a new monitor. The adapter apple sells goes from female VGA to mini-DVI. What kind of cable should I get as well:female to male?

    If I use an adapter (female VGA to mini-DVI) for my iMac 10.4.11 OSX, I also need a cable. Should that cable be female VGA to male VGA?
    Permanent vertical lines have appeared on my display, and connecting to another display (monitor) requires a cable and adapter. I want to be sure I am purchasing the correct cable for the Apple adapter. 

    What made me think I need to format if I upgrade the OS?
    I just presumed so really.
    What made me think I need to constantly format computer with my problem?
    Well, after many attempts to repair the drive, which fails, cannot even reach the log in screen, I am left with no other choice?
    And also, I have to note now, System Preferences keeps crashing without reason, it either takes ages to load, just by clicking it to open, or clicking something within it, or it just crashes.
    And temporarily, it freezes the computer totally, with no response.
    Seriously, am I missing a system file or something? Anyone experienced this problem before?
    My computer is literally a blank computer right now, installed VLC and Shades, updated Adobe Flash Player, installed Skype and Adium. I would say Growl from Adium caused it, but it has happened prior to Skype and Adium. Any ideas anyone?
    Thanks,

  • Thick black line through iPad 1- will screen replacement work?

    There is a 2 inch black line through the width of my iPad 1. iPad is out if warranty and apple genius told me the only fix would be to buy another one. Could I fix this issue through replacing the LCD screen? Any suggestions would help.

    Might. Might not. Could be part of the backlight is bad. Could be the equivalent of the graphics card is bad.
    Dunno how much your screen replacement is but you may want to weigh that cost against it not working and you paying and still not having a functioning device.

  • Field of vertical lines all over Macbook Pro screen? (+ freezes, beeps)

    Hello, everyone.
    Here's my sitch: my MacBook Pro has really been acting out in terms of freezing with fields of vertical lines. Sometimes the screen will revert back to be free of the lines but remains unresponsive OR it shuts itself down and beeps. Sometimes it fails to wake up after sleep and when I attempt to power it on, it beeps. I took my Mac to a service provider and thinking it was a RAM problem, we ordered and put in new RAM. The problem persisted and then the logic board got replaced. Everything was seemingly fine and in working order when one day a kernel panic occurred and everything was happening all over again. I just brought it back to the service provider and we re-installed my original RAM that came with the Mac. It worked fine at first, but then the RAM beeps occurred again as well as the field of vertical lines that halt the whole system. At this point I'm simply confused at what could be the problem, as the Apple Hardware Test detected "no problem found,"  the PRAM/SMC have been reset, it booted up completely fine in safe mode, and I've run Disk Utility on Command + Recovery. The Apple Diagnostics tag also says that everything seems to be OK, but what could be the root of this problem??
    Does anyone have any insight or suggestions on this? If so, please let me know. Needless to say, I'm tired of dealing with Mac issues when I really need it for schoolwork and such. (Sidenote: I also no longer have a warranty and for my logic board I got it replaced via an Apple Customer Care Code). Anyhow, many thanks in advance to anyone who might have some input on the matter!
    PS. This is what it looks like. These pictures are from two separate occasions whereby the Mac froze and these distorted fields of vertical lines popped up.

    Since it was an intermittent issue with mine I took videos/pictures of whenever my laptop locked up. I then showed them to the genius when I took it into the Apple Store. After explaining my situation to them they agreed that it was an unusual problem and replaced my logic board out of warranty for free. I would suggest doing the same but the situation and circumstances may vary so they may not offer the same to you. However, it does not hurt to try.
    Also, as I mentioned to mchanxo Apple does offer a flat fee of $280 to replace any hardware that is going bad including the logic board. That could be another option but my concern with that is if it only applies to hardware that does not pass the Apple Hardware Test.
    Another thing to note is that the genius told me that the in-store Apple Hardware Test does not test to see if the ram slots are going bad. He said the only way to test it is to put the good RAM in each slots and see if the laptop functions correctly. He also noted that if you do install new RAM you need to reformat your laptop to factory settings because the "OS originally sat on bad memory." I am not too computer savvy so I cannot confirm the validity of his statement but it is worth trying.
    Hope this helps.

    Hello:

  • JPEG Export has vertical lines through it?

    Hello.
    I was under the impression this bug (export to JPG or TIFF from RAW creating vertical lines)was already fixed with Aperture v 1.5.1?
    If so, this may be another bug.
    I am running Aperture 1.5.1 on a Mac Book Pro C2D, my camera is a Canon 30D and that's really it.
    Any ideas?
    Cheers!

  • Cyan vertical line on printing - Color LaserJet 2605dn

    In the last few days, I've noticed that every time I print, there is a thin cyan vertical line all the way down the page, about an inch from the right hand side of the paper.  See example below.
    Any suggestions for fixing it very gratefully received. Thank you!

  • My iphone3gs shuts off when i jump between apps or run certain apps...  even with 90 percent it will shut down and shows vertical lines through the black screen...  any ideas what this could be?

    My iphone 3gs shuts off when flipping to different apps or running certain apps.  If it crashes badly I need to plug power to the device to bring it up.  This happens whether i have even 90 percent battery life.  Any idea as to what this may be? 

    Sounds like a major hardware problem.
    If no change after restoring your iPhone as a new iPhone or not from your iPhone's backup, there is a hardware problem.

  • Red Vertical line through my Mac Book Pro screen

    There is RED line that comes about 10cm from the right of my macbook pro screen.... its a brand new macbook pro . Purchased last four month back .

    Hi Ben,
    It sounds like you have the same issue I had. Does your issue look like this?
    http://henhowc.bol.ucla.edu/photo.jpg
    Mine would go away by pushing the screen up and down. However, after a few months of this, the line pretty much stayed there all the time. I finally took mine into an Apple Store last Sunday and they weren't sure what the issue was. They noted that it was either related to the screen or the GPU or maybe even simply a faulty ribbon cable. They didn't do much testing outside of plugging my computer into an external monitor.
    My MBP was sent away to a repair facility. They ended up replacing the LCD Panel (according to the work order). You might want to bring it in for someone to take a look at before the problem worsens.

  • Pink & White Vertical Lines followed by a blurred screen iMac(A1312).

    Hello everyone, I have a iMac(A1312) since over 3 years now and hence not under warranty.
    The problem is it displays white and pink lines on the screen with an apple logo:
    followed by this screen:
    I've gone the forums which state this is common problem for a lot of PC's apple shipped out during the 09-10 period,
    however my Mac is not under warranty anymore. So Apple support told me that it's not covered under the replacement program.
    I've been fleeced at my local apple store a couple of times for something I later realized was a very small problem, so I would like to replace it myself.
    While I'm certain this is a GPU problem and would most likely be fixed if I just swapped it with a new one, I want to make sure if it is exactly that.
    I don't want to be in a situation where I pay a bomb for a GPU and still do not end up fixing the problem.
    Also, Is it possible to use any nVidia GPU (As is the case with Windows PC's, where just about any GPU works) or do I have to look for a Mac specific/compatible one?
    Any help would be hugely appreciated.
    Warm Regards,
    Rishav S

    I have the same issue on my iMac 27" i7 late 2009 with ATI Radeon HD 4850.
    Booting in safe mode is the only way to use it but the system can't do much and it's really slow.
    From my findings it's for sure a GPU or VRAM issue so I've just bought a spare GPU board to replace the fault one.
    Reballing could also solve this issue but usually you need also a new ATI GPU as well.
    I'm not sure about nVidia GPU but it seems that you can replace it with a more powerful ATI Radeon HD 6970M card (if you use games to take advantage of it).
    Your post is one year old and probably you already solved the issue so would be nice if you could share your solution for it.
    best regards,
    Franco
