LCD Issue. Any advice?

Hello,
I have a 22" LCD monitor and when I look at it from angle (Looking square on, downwards) I can see cracks or "veins" behind the screen. I don't want to leave it in case it gets worse when my monitor runs out of warranty. Its only in one corner of the screen.

Is this a known issue? Has anyone come across this before because I never have.

Thanks for the reply. I'll get a picture up soon if it displays in the image. You can only see it when you look down on the screen (Something to do with the way TN panels work?) Its hard to describe. Maybe the air has got into the layers of the screen or something.

It looks something like disk rot on a DVD. Like there is something in between the layers.
