LCD display problem- bright spot

Hi,
I just bought my idea u310 online. By opening laptop for the first time, I noticed the screen frame is detached. the frame was not fixed in its own place. it was separated from lcd. I pushed corners so that it can get fit in the right place. it seemed to be all right but after some hours working, I noticed a brighter spot at bottom of lcd display (bottom at task bar- more near to right side). I am very upset I afraid if the spot becomes more and more bigger ... its annoying . what this kind of problem is ? what is the solution ?
Thank you

I would say return it to get a full refund or a replacement because it sounds like it got damaged during shippment.

  • IPhone LCD display problem?

    Hi everyone,
    Recently a friend has encountered an issue with their iPhone 5. The display of the phone seems to be damaged as the bottom three quarters of the screen are a mix of pink and black stripes, both thick and thin in width. Could this be an issue with the LCD display and need a replacement?
    Please don't confuse this issue with the pink interference lines occurring on some iPhone cameras.
    Thank you for the advice or suggestions in advance.

    Hey lloyd =D,
    Thanks for the question. It definitely sounds like there may be a hardware issue with the device. However, to completely isolate to hardware let’s first try restoring the device as new:
    iOS: How to back up your data and set up your device as a new device
    http://support.apple.com/kb/HT4137
    After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
    If the issue is still present, you may want to contact Apple Support.
    Thanks,

  • Display problem - brightness and grey area

    My 24" iMAC has been suffering with a grey section (middle vertical third of screen) on start-up. This lasts for 5-10 minutes, after which time the middle section resumes its normal brightness. Recently, I've noticed another problem and that is there is very little difference on the screen between the brightness at its lowest level and when it is at its highest. What has happened?

    Same problem here (with a Mac Mini 2009 model with the same nvidia chip as your aluminum MacBook) and a LG L204WT 20" monitor. Although on my LG monitor, if I reduce the sharpness setting one step (from 5 to 4), the flickering completely stops. This does make the display slightly fuzzier, but it feels better to my eyes than the flickering. Can you test this on your monitor also, and tell me if it helps?

  • Another LCD display problem

    I've seen a lot of talk about the LCD flooding. (mine isn't cracked on the outside, but the display screen is all jumbled and it looks like the ink flooding people have mentioned; i can only see half of the menu screen)
    anyway, I'm wondering if apple will honor its warranty with this. I tried to set up service, but it's $30 for shipping and handling, and that's without any definite that they will replace my nano.
    Other than that, if I go to an apple store will they be able to give me that answer, without waisting shipping and handling charges?

    Yes, you can take the iPod into an Apple Store and see what they say.
    Depending on what happened to your display, they could fix it or not. If ink is "flooding" inside, then Apple will most likely not repair the iPod, since that is usually caused by abuse. On the other hand, if half of the display is off, it should be replaced, since that is not usually caused by abuse.
    In the end though, Apple decides what is abuse and what isn't.

  • Very unusual LCD display problem, help appreciated

    First post, I want to thank anyone who can help me in advance. I just took over my sister's MBP Unibody, and she has been having an issue where there is about a 1.5 inch wide strip of complete distortion on the left hand side of the screen. Everything in that strip is completely color distorted with constant screen tearing and flickering. I suspect there is something wrong with a wire in the lcd screen, as this problem only starts after using the computer for 15 minutes, and goes away initially by tapping the screen or adjusting the screen. After about half an hour of use however, it does not go away. In a completely unrelated incident, the glass panel cracked yesterday (This problem has been going on for about a month and a half), and i ordered a replacement, so I will be "under the hood" on Thursday. If anyone has any recommendations of what I might do to try to fix this, I would greatly appreciate it.
    3 pictures of my screen:

    Well its 70 dollars vs 600 dollars and it wasn't me who bought the applecare. And I would gladly bring it in to an apple technician instead, however my only problem with that is its not like they can just take off the glass, take a look at it and then tell me how much it costs. i mean the glass is shattered, you take it off and its going to be in pieces. Likewise, they very well might say that they can't do anything about it because the broken glass is clearly accidental damage and immediately attribute it to the lcd problem even though it has nothing to do with it. If the glass wasn't broken, I would never have even posted and immediately taken it to the apple store. Please, tell me I'm wrong and I will take it to them right away to tell me exactly why the screen is the way it is, and it will probably be covered seeing how it started out of no where. My understanding of apples policy however is that with the glass cracked as it is, they will have no choice but to immediately charge me for a full repair. But like I said, if I'm wrong please tell me and I'll take it in tomorrow

  • Ibook bright spot left bottom corner LCD on boot

    Hello Everyone,
    First post here on the forums, and I'd like to thank all those who post answers regularly, in advance. You're knowledge and advice is very much appreciated.
    I picked up a well cared for ibook g4, that I'm running OS x 10.5 on. The only fault, I've been able to find, is that on boot the gray screen, has a bright spot (almost like shining a penlight) in the bottom left corner. Would this be a dead pixel? or could it be another issue altogether.

    Hello, and welcome to Apple Discussions!
    The display, being a backlit liquid crystal display panel,
    would have dark pixel squares of they were dead; or
    if they are stuck, on one color that may have seen a
    bit of time on the screen, such as a background.
    Some people have been able to massage or lightly rub
    the area a stuck (light or dark) pixel area of a flexible
    LCD panel {the newer ones have a hard glass cover}
    and if very careful to not further damage the display,
    sometimes the pixel square that had not been active
    or had been stuck, be it a color or just black, lit up.
    I've tried this, using the back of a finger nail and to
    be sure to avoid the end where it may be sharp; or
    use a rounded small object that is not too small &
    not sharp, to gently rub around the area and watch.
    {Near some of the edges, behind the LCD panel, is
    where the cold fluorescent backlight bulbs meet
    the frame behind the LCD and its protective cover.
    There may be something in there that has moved
    over time, a bright pixel, or maybe a sample defect.}
    A very bright light, on the other hand, may not be
    just a white color, stuck, there may be a problem
    in the mask or edge of the LCD panel where for
    some reason, the cold fluorescent backlight shines
    through or around the LCD panel, set in front of it.
    Since I am not an expert, I can only tell you what
    I know and have tried; and I also have read about
    this kind of issue with stuck-on, or off, LCD bits.
    There had also been some software that could test
    and change colors in the display, to give it exercise
    to see if the video processor and panel were OK;
    and to tell if there were a problem in that system.
    Not sure if the original Apple Hardware Test that
    had been included with the computer when new as
    part of the software packet (on installer DVD disc#1)
    was included in your purchase; but that may be a
    way to test the general condition of the hardware.
    It may miss such subtle items as one bright place
    on the computer's LCD panel.
    If you are in a real city with an official Apple Store,
    you may see about getting an appointment with
    an expert genius to have them take a look and if
    they have any ideas, they could share them. At
    this time, given the holiday, you may have to wait
    for some time after the first week in January or so;
    but contacting a specialist who knows Apple LCD
    and can identify the cause of a very bright place on
    the panel (by cause and cure) may also be helpful.
    Other than the expert's observation and experience,
    which would be the best way to go, I can only suggest
    some trial and error method of trying to make it work.
    And do not press hard at all on the flexible surface of
    the LCD panel. You can see the discoloration of the
    normal pixel bits on the screen as you touch it lightly.
    The back of the finger and away from the edge of a
    fingernail can be about the right tool for the job; others
    have used a soft pencil eraser (white synthetic, clean)
    to rub their display areas to do this.
    I'd suspect a very bright pin-point of light from an LCD
    panel in a small location should be investigated; in
    part to see if there is any physical damage or defect
    that may mean something more involved, or not. I'd
    go as far as to turn down the brightness and look at
    the bright place with a magnifier to see if something
    could be seen around the edges of the bright pixel.
    Since there is a plastic outer layer that should protect
    the LCD panel, there should be no outward evidence
    of someone accidentally pressing a sharp point into it.
    Unless there is obvious evidence, I'd think it was a
    stuck pixel... Or some minor defect in the panel.
    If only a stuck pixel, a tool such as JScreenFix applet
    may help, it runs a series of colored random shapes
    in a pattern and that may reset the color of the LCD
    so all of the supported ones are exercised.
    Some ideas are presented here, along that thought:
    How to: Fix a Stuck or Dead Pixel

  • Problem with LCD display on 17" iMac G4

    The LCD display on my iMac went wacky on me yesterday. It's as though one of the three primary colors no longer works. The screen has a green tinge to it, and anything that's supposed to be black shows up as green. I've reset everything, run the Hardware Tools diagnostics (no problems found), and changed resloutions, monitor depth, and brightness levels many times. No luck. The screen is readable although very ugly.
    Obviously I can take it to an Apple Store, but does anyone have any idea what it might be? I've searched the net and the forums and can't find anything close, but I know I can't be the only one to experience this problem. I called a mac repair shop a few minutes ago, and they said that the logic board would need to be replaced. I just can't believe that because nothing else is a problem.
    Please help. Thanks.
    17" iMac G4 1Ghz   Mac OS X (10.4.6)  

    I "fixed" the problem a few days ago. Digging around here in the forums, I found another thread that gave explicit instructions on how to open the iMac and re-seat the connections. Here is the link (http://discussions.apple.com/thread.jspa?threadID=196785&start=30&tstart=30). It's a post from Androcles made on 3/26/06.
    Just as he indicates, when I did this I found nothing to be loose at all, however upon putting it all back together, on the 2nd re-boot all was back to normal and still is. It's amazing how clear and crisp the screen is after suffering through the green hue for a few weeks...
    Good luck, and feel free to ask me for help if necessary.

  • Bright Spot on Macbook Pro Retina Display

    Anyone else have a bright spot on their retina display?  MIne has a defect that looks like a bright or bleached area 1x3mm.  It is not dead pixel(s).  The spot is about 13cm from the right and 6mm from the bottom.
    This and big issues with it running a Thunderbolt display is leading me to return them both.

    If people coming here for a bright spot on a MBPR screen, maybe you should see this thread which is going on too. https://discussions.apple.com/thread/4042189?tstart=0
    My opinion: replace the whole machine not just a screen! use your 14-day return policy, do a full refund and order another one if it's necessary. Repair the LCD or replace it with the new one it might be good if it happens after a year or even two years but not for one-month year old machine! They should s.uck it up and replace the whole thing and do the d.a.m.n QA better next time.
    Thanks and good luck

  • Insignia 26" LCD TV/DVD Combo display problem

    My Insignia 26" LCD TV/DVD Combo has a display problem when you turn it on it is very bright, changes to verticle stripes after about 10 minutes of "warm up" you begin to see a egraded picture and after a little more warm-up the picture finally comes through clear.  I am past my warrenty period but I would like to fix the TV rather than throw it away.
    1) can someone tell me what the problem is
    2) identify the part that needs replacment and the cost
    3) estimate repair cost if I brought it in to be fixed
    Thank you

    Try setting the input to antenna and then scanning. If that doesn't work, you will need to get a tuner box.

    I noticed the bright spots on the ipad retina display in a black image. Used only 2 weeks.is it normal?

    No its not normal. I'm not sure how big these bright spots are, but it could be a hardware problem. Without more details, I would suggest that you take it to an Apple Store or take it back to wherever you bought it and let the, evaluate the iPad.

  • Bright Spot on Macbook Display

    My Macbook is just over 3 months old and has developed a bright spot in the display - where the pixilation color is a faded and does not show full color, creating a white spot when viewing certain colors.
    Has anyone ran into this problem before?
    Should I call Apple with the problem?
    And everyone's favorite question,
    Will this be covered by the warranty?

    It should be covered and you should call Apple or go by a store for help.

  • Bright spot, LCD pixels OK

    Hi all,
    My MacBook pro showed suddenly a very bright spot on the screen (just above the text 'van den'):
    http://www.flickr.com/photos/57660179@N04/5307076958/
    No LCD pixels are broken. Too me this looks like a LED driver problem: One LED is powered at 100%. I think this should never happen, even on the most brightest screen mode. At the back of the screen, the Apple logo is a little 'bubbled' right on this bright spot. This could prove the problem of an overheated LED, right?
    According to the Service Center this is 'user damage'. Today it has been send back to let them prove it is actually user damage.
    Message was edited by: Mark73

    Thanks for helping troubleshooting! The 'speedometer' scenario is interesting but not likely the cause (famous last words). The next thing happened: I turned off the computer (the screen was still OK), closed it and put it in the cupboard. 15 minutes later my girlfriend took the laptop, opened it, started it up and the strange spot was there. Closing or opening could have caused the magnet to come loose.
    With the 'bubbly' Apple logo I meant there's a little 'hill' in it exactly at the location of the strange bright spot (upper left of the white Apple logo). I do not know how thick that white plastic logo is, but I guess something has to press very hard to deform it. Maybe it is just a coincident and is it due to some inaccuracy in the plastic.
    When the service center is not willing to fix it, I will try the paperclip and sleep test, good ideas! Maybe that will convince them.
    btw, is this irreversible damage? Maybe the screen is OK when the pressure is gone? If so, I will try to fix it when the service center still refuses to repair it under warranty. It saves me a 500euro bill ...
    Anyway, I will keep you informed about this story.
    Thanks & best wishes for 2011.

  • Faint White spots on LCD Display

    Hi,
    I have a few faint white spots on the LCD display of my Macbook Pro. I had similar problems with a previous Powerbook G4. The white spots are about the size of a Canadian nickel and are right in the middle of the display. Since they are in the middle of the display, they are quite annoying. I already tried cleaning the screen many, many times.
    I tried to call Applecare but they wouldn't even listen what I had to say since I was outside the 90 day phone support. I was under the impression that the Macbook Pro had a warranty of 1 year; but if they won't listen to what I have to say, how can I get them to do any warranty service on my laptop?
    Any suggestions or comments would be greatly appreciated. Thanks.

    Hey everyone,
    I've also experienced these same "white spots" on my Mac Book Pro. I purchased it about a year ago and they started appearing on my screen in October. It looks like someone used their finger tip and applied direct pressure on my display. They almost form a perfect circle pattern in the middle.
    I took my computer to an Apple store in Toronto and they couldn't diagnose what the issue was so they did the screen replacement under warranty.
    Unfortunately, it began happening AGAIN a few weeks ago and I took it back to a store today to have a "genius" look at it. Immediately, they said that it was a result of putting too much pressure on my screen. I wondered how the heck I could have accomplished this since I thought I treated my MBP like a baby. I was using a Crumpler laptop bag to tote my baby around and according to them a combination of; all the gear I was carrying (which isn't much), the fact that it was a shoulder bag (resting on my hip when I walk), and the fact that I use one of those Marware keyboard covers together (which applies pressure from within) contributed to the pressure put on the center of my screen. And ultimately, they won't replace the screen because it's "my fault".
    I'm just bugged by it because...
    1) The genius I originally dealt with didn't know what the problem was so I couldn't take any measures to better protect my computer after it was repaired. I could have bought a tougher case, made sure I was more aware of what else I put in my laptop bag (although I never put that much in it initially), or just left it at home.
    2) The genius (who was quite rude actually and treated me like I was stealing from him) I dealt with the second time said he saw this issue quite often but there is no warning anywhere saying that the Mac Book Pro can be succeptible to this. Geez, I have friends/family with Mac laptops that treat them like crap and have no issues like this. Also, I know people with PC laptops that are built like tanks (who spent a fraction of the money I did) and can put up with alot of day to day punishment.
    3) I bought the Marware keyboard cover AT the Apple store. Why are they selling something that has the ability to damage their laptop screens?
    So I hope people can read this and take the proper precautions when storing their Mac Book Pros during transport. Luckily, the spots aren't too bad, I just make sure my desktop wallpaper is dark so the spots won't be so obvious.
    Sorry Apple, you just lost a point with me.

  • "Bright Spot" in the middle of the display.

    Hello...
    A few months ago, my iBook's screen appears to have developed a "bright spot" closer to the middle of the screen. This bright spot appears to be a vertical line that vaguely resembles an exclamation mark. It's definitely not a group of dead or stuck pixels, but it's looks a lot like the "white spots" that some early 15" Aluminum Powerbooks had, maybe not as intense: http://www.apple.com/support/powerbook/displayprogram/
    I might want to ask for a screen replacement. But my problem here is: I bought this iBook when it came out last summer in Canada. Right now, I’m not in Canada, and I asked the local Apple Service Center about the warranty. They said that they don’t cover any Mac that wasn’t bought from the region they belong to. This contradicts Apple’s international warranty for its portables.
    My question here is: Is my iBook’s screen eligible for replacement in the first place? If it is, how am I supposed to deal with the local Apple Service Center?
    Thanks in advance!

  • Apple logo bright spot on macbook pro display.

    Recently I found a bright spot just behinde the apple logo on my macbook pro mc 723 (early 2011) display...it seems that the light of the logo passes through the display...what can I do for it?! It is so bothering especially when working on a white or bright gray screen...

    Yes it it because there is a bright light behind the lid, in the room/area you are in, and it is shining through the white Logo onto the screen. Place something over the logo or turn off the light you have on behind the lid.
    EDIT:
    There is No light in the Logo. It is lit by the lights in the the screen. If you dim the screen the logo will also dim. It is because there is a bright light, floor or desk lamp, behind the screen. Turn it off.
