Question about screen fading to white?

let me first say that my experience with the apple support staff has been great.
I took my PB for repair due to a problem with freezing and panic alerts. In addition, sometimes when it freezes, the screen slowly starts fading to white. You can still somewhat see the image (i.e. the background or application), but it's almost as if it's become a "negative" image, just like the negatives you get when you get pictures developed... exept extremely bright white instead of dark brown..
I hope this makes sence...
anyway, The first time I took it in, they replaced the harddrive, case (bottom part was warped), and cords/bus something or other connected to the logic board.
I'm still waiting for them to complete the repair, but the local genius thinks it might be something wrong with the logic board itself..
I was just wondering if anyone else has seen this problem before...

Hi Spencer,
Sounds like it could possibly be a hardware (ie. logicboard or video) issue. Since you've already sent it in for service it's probably best to wait and see what the technician(s) find rather then engage in idle speculation, like I just did. Anyways, good luck.

    I was just scrolling through my apps when the screen suddenly froze. A force shutdown didn't work and when I pressed the silent on/off button, there was no vibration either. The frozen screen faded to white with a few lines and about 10 minutes later, the edges started to turn black, forming a ring which got larger till about 4 hours later, the screen turned completely black. I tried connecting to iTunes but it wasn't detecting the phone and I can't do anything with it now... When it turned completely black, I charged it and after a while, the low batt screen came on but it was fuzzy and flickering with the white ring... What to do know ???????

    Restart your computer while holding down left mouse key. That will eject the CD and your Mac will start as normal.

  • A question about screen updation of T61

    Hi there
    I got a question about screen updation. 
    Currently, my T61's screen is 14.1 XGA TFT 1028x768, and it can't work, thus I am considering to replace it with the better 14.1" SXGA+ LCD SCREEN .
    However, I am a little concerned about the compatiblility problem, hence I just wonder whether the new SXGA+ screen can fit for my current T61 laptop or not?? Thanks a lot for your answers!
    Regards
    Peng

    you can buy it from IBM parts, and it will then sure to work for your laptop.
    Here is the manual that shows you how and what parts you need:

    P.S. If you have warranty this upgrade will void your remaining laptop warranty, as the LCD is not CRU (customer replaceable unit).

  • MacBook Pro 13 Inch, Mid 2009, Screen Fading to White/Purple

    Recently my MacBook Pro 13 Inch screen started having problems. At first the right, bottom corner of my screen started flickering and have small, white, lines that would flicker and simply go away after I adjusted the screen a little. Then the whole screen would spontaneously start fading to white/purple. It happened once or twice a week the first time, but now it's happening repeatedly, over 5 times a day. It's gotten to the point where I can't seem to make the fading go away by moving my screen, only by completely closing my MacBook then opening it up again.
    The screen usually starts fading when I move the screen back or open my Mac. When the screen goes white/purple, everything else works, the audio, mouse, keyboard.
    This isn't my mac or my video but it looks like this: http://www.youtube.com/watch?v=f6MhluTYfYw
    I did a little bit of Google-ing and reading the Apple Discussion forums and found that this is a pretty common problem. Some people say that it's a loose cable, or a pinched cable, or the screen itself, but I'm not sure on what it is, all I know is I want to get it fixed.
    My questions:
    - Is there anything I can do to fix it?
    - How much will it cost to get it repaired? (My warranty ran out)
    - Where's the best place to get it repaired?
    Thanks,
    Josh

    Same problem mate and also out of warranty. Took it to the Apple Store, they had a quick look at it in front of me and told me it needs a new display. Quick job for them but it costs £280. Definitely seems like a loose connection to me, due to excessive opening and closing. I'm quite reluctant to open it up myself but after seeing a few videos on youtube, I think I might give it a go and see if I can fix it myself.
    I wouldn't trust anybody else than Apple to fix it if only it wasn't so expensive.
    Let me know if you find any other way.
    Thanks

  • Why was my screen fading to white?

    So I got my MacBook two years ago. After about a year, my screen started slowly fading to white and acted slow out of nowhere. The recent times I used it, my screen no longer turned white but it was still so slow. I went ot the Genius Bar recently (which is absolutely great!) and the one who helped me said that I had an anti-virus program, Symnatec that slowed down my programs because it checked if there was a virus in everything I did. He deleted the app for me and he suggested I upgraded to Mac OS X Mountain Lion but my RAM was at the bare minimum of 2GB. So I went to a computer place in the city where they could add more. I upgraded to a 3GB RAM and upgraded to Mac OS X Mountain Lion. My quesstion is, why did my screen fade to white but then stop out of nowhere? Will it happen again? Please let me know ASAP! Thank you!

    A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that Mac OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.
    SMC

    The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
    Lights
    The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
    The Status Indicator Light (SIL) appears to behave incorrectly (on Mac computers that have an SIL).
    Battery indicator lights, if present, appear to behave incorrectly (on portables that use non-removable batteries).
    The display backlight doesn't respond correctly to ambient light changes on Mac computers that have this feature.

  • Tecra 8200: Question about screen 14.1 replacement

    Hi, my screen only shows the left hand side, a line goes down the middle and the right hand side is blank. If I hold the screen outer tightly on the top left hand side, the whole screen lights up as normal. I have attached a remote screen and this works fine. I have been told this is a screen fault.
    The screen part No is LTM14C438, they are very expensive. I can get a different screen number (LTM14C433), which is a 20 pin toshiba from a TE2000, and I am told it will work.
    Can anyone confirm this, thanks, Allan

    Thanks for reply. I saw a screen on Ebay and asked the question, the reply was that he did not know for sure, however if it was a 20 pin connection and the conection was in the same place, he was sure it would work. I was just trying to confirm. I rang Toshiba, they gave me 3 compatibale Part No's. They then informed me a new screen would be about 284. I am persisting with a remote screen until I find out one way or another. Thanks again. Allan

    Questions
    1) Accelerated Graphics Port - there is enabled if yes that that it is necessary to make that it became accessible.
    2) whether Frequency of hertz with 60 can be raised even up to 75.

    Hi
    I have noticed that on some Toshiba notebooks the screen refresh rate is fixed on 60 Hz.
    The display refresh rate is not important on the notebook screens.
    TFT matrix doesn't have such thing as refresh rate. It doesn't blink.
    TFT like all other LCD screens doesn't have refresh rate parameter, only reaction time.
    Your eyes are safe ;)
    Ps: As far as I know the AGP port is not available.

  • Question about screen protector (ipad2)

    Hi,
    I just applied a screen protector on my iPad 2 and I've noticed that it isn't 100% straight:
    The front camera doesn't sit exactly in the protector's hole.
    Actually, the hole in the protector kind of sits in the center of the camera.
    It doesn't disturb the images, but is it can do harm to the camera in some way?
    Thanks :)

    No it won't harm your iPad, but it might cause picture distortion on the edges of the photos. If your pictures look fine then you are OK.

  • Question about screen share

    Hello all
    Very happy so far with Leopard (except for not being able to use TM with airport disks!)...anyway, does anyone know why I can connect from a Macbook to a Powerbook and share the screen an so on, but I cannot connect the other way round (Powerbook to Macbook). When I click on the Macbook in the sidebar, I get the connecting dialog and thats it !!
    Any help will be much appreciated
    Thanks

    All sharing services are off by default. Even if it was turned on, someone would have to know the password of one of the user accounts on your computer in order to access it.
    I don't think there's a log of screen sharing, but while it's sharing the screen with someone, a screen sharing icon (I believe it actually flashes red to let you know it's there) pops up in your menu bar.
    If you have WPA security on your network, there's virtually no chance that someone could've gotten into the network, much less started screen sharing with you.

  • N8: question about screen lock during calling

    I really like my N8 but there's annoying thing. While I'm calling, in the most cases the screen turns on and with my face I press the buttons on it. So I always end my calls unwantedly or turn on the speakers...
    Is there any solution for that? I've not found any settings or software for that yet.

    Sounds like the proximity sensor is faulty on your phone. You should have it checked out at your local Nokia Care point.

  • Question about screen protectors

    Does anyone use the invisibleShield for the iphone?
    I am just wondering if this particular brand is easy to install and how well it protects the iphone.
    It's $20 so it should be worth it. It's avaliable at walmart.com

    i could not get mine to sit right and i spent ages trying. Waste of time for me. Their youtube add makes it look easy but its not. Also there is a new design of cover for the 3g - the old design for 3g was hard to make the corners work and its supposed to be easier with the new 3g design - you need to check you get the right one.
    You must also make sure you do nto spray the phone with the liquid - some guy on youtube siad that this water detector (it goes pink when the phone goes is water and means apple will not replace if something goes wrong) has now gone off cos he sprayed the skin and it got all over the phone
    good luck

  • IPhone 4 screen black and white?

    So, title might be a little misleading - I don't know, but my iPhone 4 has broken.
    Basically, I can still hear it turn on etc, still hear when I get a message or a phone call and so on, and it vibrates when I put it on charge etc. What I'm trying to get across is the phone is 100% functional... except one thing.
    The screen is black. That's right, black. It lights up a tad when you press the sleep button as you usually would to get into the phone, which makes me think the LED's are still working and connected. 
    Oh, also, this just happened when I picked up my phone one time. Just black out of nowhere.
    What I've tried:
    Recovering phone (Phone wont recover for unexpected error).
    Holding down home and power button for 10 seconds (only worked once out of about 100 times, where the Apple logo showed up, then the screen faded to white then went from white to black and the phone was off again).
    Opening the back of phone to see if a connector has come loose (It hasn't).
    So, basically, if anyone could help I'd be extremely grateful.
    Thank you.
