    Hi guys,
    before some months i spilled some Water on my notebook.
    About 3 days afterwards, when i startet the notbook, i noticed that the screen was dim and flickering. I could still use it, but only in a dark place. i found that it wasnt a software problem. Asked an experienced friend about it and he said that there was a problem with the hardware and we found the place with the problem( i uploaded the pictures). it looks like its burned. He told me that this could be repaired easily by someone who has the right equipment, he didnt have them, so he couldnt do it. When i asked the pros they told me they have to look on the mainboard first, the pictures i made were not enough( maybe there could be other problems). And even for opening it up they wanted much money. Could someone please give me some advice what i should do now or does anyone know what to do. Is this even repairable? Or is there any different way to solve this problem.
    I am studying architecture, without my notebook i'm dead.
    Pleeeeeeease help I appreciate all advice.

    Since you already extracted the PC boards, using Isopropyl Alcohol (>90%), use a soft brush and "gently" clean the PC boards. Use a soft fiber cloth to mop up excess fluid.

    That's not good. Put the chassis back together making sure the interconnections are also cleaned and then snugged.

    Look in the BIOS and see if you can increase and decrease the luminosity from there. If yes, boot in to Windows.

    Then see if you can use the Dell HotKeys to increase and decrease the luminosity.

    If the screen still flickers well... it may be on its deathbed.

    Sadly I think your friend was correct.

    Looking at IMG_4582 there seems to be a cracked component and 2 solder pads that could have had a component on them that's disintegrated. You would need a hot air station and a circuit diagram or some other way to check what components need replacing. Even then if the board is charred it could have become conductive and that might not be fixable.

    Unless you can find someone willing to try to fix it for a decent price (which is highly unlikely) you're looking at a new motherboard at the very least.

    I think you would be better off getting a new laptop.

    If you connect an external monitor or tv to the laptop, can you see the images better?
    Of course if the video chip on the board has a problem, the external monitor would have the same video problem. Butperhaps the brightness on the external can be increased more than the laptop allows.

    The screen brightness on the external monitor was alright, there was no problem. There i first thought that its maybe a hardware problem, and so it was.....
    On my laptop i cant increase or decrease the brightness its always dim:/
