Page 1 of dodgy picture on my tv

I purchased one of those Samsung 28" flat screens from Sky buy a few months ago and have started to notice a weird bending of the picture especially on dvd`s at the top of the screen.

The easiest way to describe it was when I was watching a rugby match the other night the uprights were not exactly umm upright. More bendy than upright.

Any ideas?

Any magnetic field (loudspeakers) close to the set, failing that I think its warranty callout to reset the screen linearity (convergence???????).

I know what I mean it may even be right.
