Tv out Radeon 9000

[Itaiwe]

I connected my Radeon 9000 video card to my Tv (Grundig). I can see a picture after I fallowed the instructions manual I got with the card.
My problem is that I have this waves going up and down my tv screen and I don't know how to fix it...
can anyone help ?
what do I need to change in the card's settings in order to stop this waves?
thanks,
itai

Same reply as in the Tech Support forum (you shouldn't cross-post, by the way)

Unplug the coax cable from the back of the TV.
