Backlight Works But the display is not

I recently changed my logic board with a used due to a hardware problem.After the installation the MB works fine except that my display is not working (the backlight is working. I connect to an external Display and it works fine. Please Help!!!!i Double check the data cable for screen. Is there anyway to check my hardware for a problem. Unfortunately here in Greece the support is not so very quick and it is very expensive

You might want to try your homeowner's insurance or see if your credit card offers some protection (that is if you used one to buy it).

    I dropped my phone in a toilet, the sound and vibrate are working but the screen will not turn on, what should I do? do I just need a new screen or what? I'm freaking out here

    Don't freak out, just get over it. It's probably done.

    Apple may offer you an refurbished iPhone in exchange for yours, for about half the cost of a new one.
    I wouldn't be too specific about just how it got wet

    Apple really does not repair your iPod except for battery replacments.They exchange your iPod for a refurbished on of the same model. For a 4G, the price is $99, $149, or $199 depending upon the capacity.

    A third-party place like the following may be less expensive. Google for more.

  • My iPhone went through the wash. It works but the display screen is still black.

    My phone seems to work but the display screen is still black.

    I'm sorry to hear that. If the display isn't working you can take the phone somewhere to see if they can fix the display.
    I would honestly take it to Apple and get it swapped out for a new iPhone. It will cost you money because liquid damage is accidental so it wouldn't be a free switch out they would charge you for an out of warranty price. That is the best way. The only reason they switch out the iPhone is because liquid damage in unpredictable of what it damaged.
    Hope this helps.

  • What should I do if I spill liquid on my macbook? The machine is working, but the keyboard is not.

    My grandmother spilled coffee on the trackpad and it reached the first row of keys. The power didn't go out, but the keyboard is not working. Any suggestions?

    Spill Cleaning
    Some liquid has just spilled into your Mac. What should you do?
    Do
    Immediately shut down the computer and unplug the power cord.
    Remove the computer's battery (if you can)
    Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
    Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
    Note what was spilled on your Mac.
    Bring the computer into an Apple store or AASP as soon as possible.
    Don't
    Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
    Don't shake the computer (this will only spread the liquid around).
    Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).

  • My iPhone4s works but the display...?

    Earlier today, I was using my iPhone 4s, playing games as I normally did. At one point, the screen slowly got darker, like it was fading away, but then returned to normal display. I did nothing to cause this, I was just playing. About a minute later, it did the same thing. I'm not very sure how to explain it, but the screen turned black and there are blue vertical stripes. I tried to reset my phone on itunes to no avail and have restarted it numerous times. When you turn it on, you'll hear the sound it makes when it locks and unlocks, and it buzzes if you put it on silent, but you don't see anything on the screen. In the very beginning you could see pieces of the game I was previously playing in shades of blue and black, but now it is purely blue and black.
    Is there any way I can fix this? More importantly, what is wrong with the phone?
    Update: I've been playing around with it a little. i managed to take pictures, though nothing came up on the screen. Sometimes there will be lines that change color to red, or green, or like a skin color.

    I'm sorry to hear that. If the display isn't working you can take the phone somewhere to see if they can fix the display.

    Does the old version of the application work on the same PC?
    What happens when you run the .exe - does anything come up on the screen? Do you get any error messages?
    I don't speak german so I don't understand the message that appears - but it seems to be saying something related to the 'program not installed'? Was there previously an installer that did custom actions (e.g. running other installers or putting files/registry keys in certain locations)?
    1. yes, it is running fine in the development environment. There are no errors when I start the main.vi. I can open the program and work with it etc.
    2. yes, the old version is working. It's 2009, I installed 2009 Runtime and I can open the .exe and work with it.
    3. concerning 2009 .exe see my answer at 2. When I start .exe which is converted AND build in 2014, the first screen is working. Then I press the "Übernehmen" Button and I got the attached error. Yes, it says "the program is not working".
    I don't know if there were custom actions. I got this project from a former colleague... :/

  • MessageDriven Bean problem.Working but the queues r not getting cleared

    I have written a simple message driven bean.It just sends a message to an another queue myadapterqueue
    on getting a message .
    It is working. But the problem is if I restart my application server then it again reads the messages which had been sent to it earlier.Also the queue size is
    not getting to 0 bytes after it has consumed messages.
    My application server is JBOSS2.4.3
    I think I have to specify some attributes in the
    descriptor files.But how??????????????

    it is unclear whether you are commiting on the first queue or second one.
    but it appears like you have created a transactional problem across the two queues. although you commit on the first queue, this commit is not extended to the second queue.
    things will be fine unless you get an exception of shutdown.
    if you shut your message provider down first then you cannot send the message to the second queue. (assuming that queue 2 is also on the same server)
    if you shut your MB app server down then you may be in the middle of accepting a onMessage callback from the first queue.
    do you have another MB that registers this one as a listener, or are you infact sending a message back onto the same queue...
    public void onMessage(Message msg){
    try{
         this.sender.send (msg);
         //your server may shutdown here and leave messages on the first queue. and send extra messages on the second.
            this.session.commit();
            System.out.println(" Message");
    } catch(javax.jms.JMSException jmse ){
            jmse.printStackTrace();
    }

    If your pictures and video are not on the camera roll, I do not think your iPhone is taking pictures and video.
    You have already tried resetting and restarting your device.   Next, check whether your camera has been disabled in Settings > General > Restrictions > Camera.  If not, ask your Apple Authorized Service provider to check your device or contact Apple Support for help: http://www.apple.com/support/iphone/contact/

  • Connected monitor works, but the comp. does not  "see" it

    ello,
    When i plug in a monitor it will clone the display, but system prefs only shows the laptop LCD

    Hello, I believe that is the case when the Display is "Mirrored"... how else could it be? You can't change the Rez or Depth of one without the other, can't drag the MenyBar/Dock to the other one!
    If they are Extended Displays, they do show up as separate ones.
    They're essentially one Monitor when Mirrored.

  • Laptop works BUT the screen will not turn on

    I have a Macbook Pro 15'' intel from 2007. Two days ago I closed the top and when I re-opened it a minute or two later the screen was black. Thinking it was just asleep I mashed on the keys - nothing. Yesterday I feared it was a issue with the computer. Thankfully though I have successfully log in (blindly) and was able to use a hot key to open iTunes and start playing music, proving that the computer itself was alright, but the screen was busted.
    Does anybody have an idea of what I can do to get the screen back on? Could it possible be a problem with the activation switch that turns the moniter on and off? (is this problem covered in my Apple Care warrenty?)

    Hi Hank,
    Does the NVIDIA issue sound about right?
