Hi all, my toshiba 34-inch CH7 make an anoying "electric" bzzz sound (like that of a transformator). I can hear it when the sound muted (or if ther's silence in the show played) or when I change channels in my cable descrambler. it gets lowder when I rise contras or change cable channels. I can even detect variation in the sound when subtitles are displayed in a movie(lowder a bit).
please help.
thanks
