    Display problem?


    Hello there viewers of Windows SevenForums,

    Sorry but I wasn't sure which category to put my problem in but this was the closest category to my situation.
    So I happen to get my laptop back from my very close relative and I've been told that the display screen on my Dell Latitude E5420 isn't working correctly. I've also been told that my friend did spill some water onto my laptop (this may be the cause of my problem). I'm not entirely sure where on the laptop he spilled it on.
    The good thing is that my laptop is still usable but whenever I turn on my laptop; the screen is entirely black.
    According to my documentation, I can turn it on, black screen, the fan is somehow very loud than usual and after at least 5 seconds. It shuts itself down. I assume maybe a wire is corrupted from the water spill?

    I have opened my laptop and dissembled most of the parts of my laptop. Even separating the display screen from the main frame. BTW I have dissembled/assemble my laptop more than once.

    Any questions or suggestions will be answered.
    I can also upload pictures if needed.

    What happens when you plug in a monitor to the VGA or HDMI port on laptop? If no monitor will work then it's likely the GPU chip.

    Did you check the monitor wiring closely to see that it is plugged in correctly when you took it apart?

    Damn, I've already dissembled the laptop apart. But I will plug in a monitor into the VGA port after I assemble back the laptop. Either way if it is the GPU chip that's fried from the water spill. It seems I would have to replace it perhaps?

    When I gave it to my relatives; I already assembled everything back together and it worked just fine.
    But now you ask if the GPU chip is most likely the reason why it's not working. I would bet my money on the GPU is fried. What would you suggest I would do?

    Hi zilean0475,

    As correctly suggested by gregrocker check the laptop with an external display. It will help us isolate the issue between LCD and Graphic card of the system.

    Also, let us know if you hear any beep codes from the system. And let us know the status of the lights on NUM,CAPS and SCROLL lock keys.

    Keep us posted with the results so we can advise you further.
