Dust behind screen in T60p monitor

[Icee]

I've had my T60p for just over a year now and its been a pretty stable machine. I've noticed however that dust about 4 to 10 pixels high is making its way behind the screen. You can see the parallax between the screen layer, the dust and the back panel.

It used to be just one piece that was close to the system clock/task bar so I really didn't bother me, but now there are a few more puffs of contaminants that are making their way behind the screen all over the place.

I thought the LCD screens were mostly sealed (not weather proof of course) but has anyone else had this problem?

Is there a way to get it serviced if it gets worse?
