Weird red noise on black screen(laptop)

[levak]

Hey there

A few days ago I turn on my laptop and my screen looks like that:



There are also green and blue stripes when background is in other colors, but black always has this noise, even when I'm watching a movie...
If I plug my laptop to external VGA port, picture is perfect.

What coudl that be?
Faulty graphic card?
Faulty graphic card-LCD cable?
Faulty LCD?

I came across a case at work once where I guess someone managed to jostle a VGA connection loose enough to where some colors where fucked but the picture was otherwise fine. I think the monitor OSD displayed the right colors though, which was enough of a hint to check the cable.

That doesn't really look like the GPU or LCD failing, my first guess would be the connection.
