HP TouchSamrt 520-1001 (one red sub-pixel on the screen)

Hello!
Yesterday I bought a computer, and now on the screen I saw a large red sub-pixel. I am very upset, because it costs money. How to solve this problem? How to fix this sub-pixel?
I bought the program JscreenFix, but it did not help. (((

There is a pixel policy and it requires that a specific number of pixels (plural) be bad within a certain radius. One bad pixel does not make a warranty claim. All laptop makers have similar policies. It is a holdover from the days when a laptop screen was much more expensive than now and frankly I think it is time to stand behind the product a bit better, but all you can really do is make a nuisance of yourself and see if they will bend the rules.

  • 1 dead pixel on the screen

    I seem to have a dead or stuck pixel on the screen. How do I know if its dead, or if its stuck? Do dead pixels look different from stuck pixels?
    Im not to bothered about it as I can hardly see it and I struggle to see it, but it is slightly annoying that you know its there. It looks turquoise colour, but when I put some black over it on the screen, you cant see it.
    Also, I have downloaded the stuck pixel fixer and run it for about 20 minutes, and it doesnt seemed to have done anything.
    Does anyone suggest what to do? Also, does apple have a pixel policy? Like I said im not to bothered by it, but when you know its there it can get a bit annoying. I have to really look for it to see it though.

    Yes thats what I was thinking. Like I said im not to bothered about it and I can hardly see it, but might give them a call and see what they say. Its not acually to bad. I have dead pixels on other things before and they have been much worse. It must be because of the resolution of the screen or something.
    I have to say, the one thing I hate the most and is the most annoying thing out of all technology for me is a dead pixel, esspecially when its right in the middle of the screen. This one is just at the top where the program menu bar is, so its not to obvious. Infact, its probably the best place it could have happend really, if it were to happen at all.

  • IPhone isn't using all pixels on the screen?

    Hi All
    About one month ago i finally pulled myself together and bought myself the iPhone (great phone ) however, i just looked closely at the phone today and noticed one thing. When i am looking at the border of the screen (right before the "real black" it is, as if there are a row of about 3 pixels around the screen. That aren't used. Is that a faulty phone, or is that normal? (i will try to post some pictures when i get home later tonight)

    yeah i still think its a new problem for me...i didn't notice it for the first 4 months i had the phone and then all of the sudden i did a month ago...i just don't care enough to send it to apple and be phoneless for a few weeks

  • How can I migrate data from an old MBA to a new one without having access to the screen of the old one? The screen of the old MBA is damaged !

    How can I migrate data from an old MBA to a new one without having access to the screen of the old one? The screen of the old MBA is damaged !

    If your "older" MBA has a Thunderbolt port then it isn't that old. See Target Disk Mode about how it's used. Note that without a monitor you won't be able to tell from the screen when it has fully started, and if it succeeded in starting in TDM. If it did, then the hard drive should appear on the Desktop of your new computer. You can then access it to transfer your files. You can even use Migration Assistant or any backup utility to transfer data. Just don't try to transfer system files.

  • Why are there 2 thin red vertical lines on the screen of my MBP 15" retina which is only 2 months old!

    I would just like to understand why there a two thin red vertical lines on the screen
    I suspect I need to bring into an apple store for diagnostics but is anyone aware of the likely cause?
    thanks v much!

    It could be a GPU issue, a display issue or a display connection issue.  The genius bar technician will offer you a definitive answer and should fix it under the warranty provisions.
    Ciao.

    I have tried holding the power home button but all that does is turn it off. When I try to start it again it goes into the same loop.

    The movie is from iTunes.   You would think that a download from iTunes to a MacBook could be watched on an HDTV using Apple TV without any headaches bit this does not appear to be the case. 

  • Late 2011 Macbook Pro green pixels on the screen where dark colors should appear.

    I have a late 2011 Macbook Pro I bought it new with 4 gb of ram. About 4 months ago i purchased 8 gb of pny ram for this model and upgraded the ram. I followed all of the safety precautions and discharged my static electricity before upgrading. It increased the speed of my mac and helps with certain tasks. About 2-3 weeks i notices my mac froze and strange green black and pink bars appeared on the screen so i hold the power button to shut it down and it solves the problem this will happen about once a month but otherwise my mac works perfect. Now about a month ago I powered my mac on and low and behold The screen was covered in green pixels. I tried rebooting twice and it didn't do anything then i let it sleep for about 5 mins opened my mac and the green pixels were gone. Now my mac is still usable and everything works its just sometimes like once in a while ill get a few pixels and closing and opening my mac fixes it. I was curious if this was related to one another or is my mac just starting to die....

    I have been getting green pixels/boxes the last while...
    I have noticed it after waking the machine from sleep. Not 100% sure if that is the only time it happens. It goes away after a few seconds, typically.
    Any idea what is going on?

  • I get a series of colloured pixels across the screen after Firefox opens, making it unreadable; how can I solve it?

    I have just installed Firefox 4 on my PC running Windows XP. Firefox opens and looks OK for a while but then groups of coloured pixels appear across the screen as I move the mouse. These grow making the screen unreadable. I have tried starting Firefox in safe mode; this is better, but there is still some of this "noise". Any ideas?

  • I have iPhoto 09 The cover of my book is cropped is perfect on screen but when I print it out it's cropped badly. There is a red exclamation point on the screen image but I have created 5 books and never had this problem. HELP

    I am using iPhoto 9 to make a book. The cover of my new book looks perfect on screen, but when print it out before I have it published the cropping is all off. There is also a red exclamation point on the cover image. I have checked and rechecked but to no avail. Can you help? Bill Perlmutter

    That red exclamation point can mean either that the image on the cover is below the resolution limit that Apple has set for photos to make good prints or that there is missing text in a text box or there's some text that has overflowed the text box.
    The resolution limit that is set in iPhoto for photos is 110 dpi, i.e. the PrintWarningImageDPI value in this screenshot of iPhoto's preference file:
    Click to view full size
    It's not an absolute thing.  Many have reported getting books that had photos with the low resolution warning indicator and it was perfectly satisfactory. 
    But check to see if it's an image or text warning.

  • Equium M40X: red lines running across the screen

    I seem to be getting red lines running across my screen( from top to bottom) as i move my mouse.any idea whats wrong. ie is it the screen or something else.
    i however connected it to a monitor and got the same problem so am presuming my screen fine.
    maybe my graphic.and if so anybody with a solution or will i just have to dismantle it..
    thanks

    Does this happen as Windows boots up or during the desktop??
    It sounds like you graphics processor is defected to be honest I would only expect this problem to occur with LCD screens but as you said it happens using the external monitor.
    Try changing your display modes to see if this has made any difference.

  • Line of "dead pixels" on the screen that come and go.

    I just did a clean erase and install, i'm using leopard with all the current updates. i noticed the system was leaving lines on the screen before the fresh install so i figured it was a software problem. well, after doing a clean install they are back. its like the video isn't processing correctly or something because i can put another window on top of the "dead pixels" and it covers them up, like the in this picture. http://farm4.static.flickr.com/3269/2442796153fb66961090o.png
    the finder window is covering an inch or so over the dead pixels. and to clarify the line of dead pixels or what ever they are appear to associate with a certain window or app and show up at different parts of the screen. for instance, if i see the lines in firefox, i can minimize the window and the line is gone.
    this is on a 24inch white imac with the 2.16 c2d.
    any ideas what would make this happen?

    There are quite a few posts about this sort of thing.
    Many peopel find some minutes to hours after the lines of pixels the Mac freezes - mouse still moves but you can't do anything.
    It's not clear if it's software or hardware.
    My suspicion is that it's a software problem but I may be wrong. Either graphics memory or RAM used for buffering is faulty, or something is inadvertently writing garbage to graphics memory.
    Most people attribute the issue to Leopard, but I'm still running Tiger.
    Lots of posts about it being an nVidia card driver issue, but I'm running ATI.
    Maybe coincidence but my 20" late 2006 iMac started playing up after a security update earlier this year.
    Some people have had graphics cards replaced and it's cured it, pointing at hardware.
    Another thing that seems to help is upping default fan speed using say smcFanControl.
    Two things that have made this less frequent for me are:
    - turning off Genie effect in Sytem Prefeerences for minimising/maximising windows (I often got freezes when changing windows)
    - running smcFanControl
    There is some debate as to whether or not for some reason the fans are not speeding up properly (software/EFI or SMC problem?) in response to higher temps and hence components are becoming unstable.
    Try some searches on 'glitches' or 'freezing' or browse through the last couple of weeks threads.
    If your machine is under warranty I'd be phoning Apple. Mine alas is not.
