My Samsung 46" LCD buzzed loudly on modified wave inverter for about 2 weeks during load shedding. Now its dead apparently the power pack is gone. My plasma runs fine though.

Turn the backlight setting to 0 and the buzzing will stop. Also change energy saving setting to highest.

Thanks for this advice. My Samsung plasma also buzzes using modified sinewave. But I did notice that the buzzing is loudest when the scene on the tv is very bright, like snow or a bright background.

I will try this and see.
