MacBook Pro 2130 screen failure

Hey guys,

I'm not a native english speaker, so sorry for my mistakes.

I have an old MacBook Pro (2130 MA464LL/A, but with 2 gb ram, and a 250 gb HDD) which I haven't used for at least a year ago, because it has got some kind of a screen failure.

I had to install Windows XP on it, and after that the colours of the screen were all messed up. I could fix it on the XP, but it still doesn't work well while running Mac. The problem doesn't occurs while using the DVI port.

It looks like something like that.

Does any of you have any idea what the problem could be? I don't think that a display replace would help it, because, as I sad, it works perfectly while running Windows.

If it's useful, I could take a photo of it.

Thanks for your help!
