I just bought a toshiba 35" flat tube. The picture is awesome, but it's making a funny sound. There's a very loud buzzing coming out of the right side speaker. Even if I turn the speakers off, it still makes the noise. It changes in intensity with what colors are on the screen, when it's black and dark colors, you can barely hear it, but when it's bright and especially white colors, it gets louder. Is it the TV or could it be some kind of interference from other components that are hooked up to it? I still have 2 weeks to send it back for a replacement, should I just do that?
