Hi experts,

I have a problem with illumination of LCD on my notebook MSI MegaBook S270.

When I open notebook only about between 0 and 45 degrees, everything is ok.
But if I want to open it more, illumination of LCD doesn't work :-(
LCD displays everything, bat it's very dark.

Can you advise me, how to repair this?

    Does this only occur when you are running on battery?  If that's the case, try using the (FunctionKey + UpArrow).  This works on mine when the laptop is attempting to preserve battery life, but it may be a Dell specific thing, good luck.

    Also just an FYI, if you aren't able to adjust it - you may just have a hardware problem on your hands and might require some kind of a replacement.

    Thanks for you comments.

    Problem remains also when I have notebook connected to electricity.

    I think this is a hardware problem. So, I'm trying to find, how to repail it.
    I mean this will by only bad contact or something like this, but I'don't know how to find it inside notebook.

    Yeah sounds like a bad contact, nothing more. I would either try to get it replaced if still under warranty or have MSI or affiliated technicians repair it as the connections could be quite tricky to try sort out yourself.

    The opening of the laptop screen is having the effect of cutting power to the inverter which powers up the CCFL lights.
    This would tell me that the LCD cable which is connected to the motherboard and travels up through one of the hinges to the back of the lcd is the culprit. The continuous opening and closing of the screen over time has caused a weakening in the cable or is pulling on the connected on the motherboard.
