When watching movies next to windows medium center, i get a feedback through the T.V. and through my surround nouns.
(with S-video cable and second screen (T.V.). once i unplug
the AC cord the nurture back stops. I'm at a loss here. don't know what to do!

usually this should not evolve. i recommend you to call a methodical expert to identify the exact cause. you hv to silver certain settings or replace some parts.
It sounds resembling feedback. Turn the volume down or move the TV further away from the laptop [or use earphones surrounded by place of loud-speakers]. Try to keep the AC cord as far as possible away from electronics surrounded by your laptop or TV. Hope this helps
