I'll try calling Pioneer again tomorrow.
I, too, have a disconcerting buzz coming from my new 150FD. It's actually coming from the panel itself, and is not simply a reflection of the normal power supply buzz every plasma display has in back. I called Pioneer, and they said a buzz from the panel is normal -- it's the sound of the plasma pixels being charged. They also said the 1080p sets are bound to be noisier than the old models, because they have more pixels to charge.
I find it hard to believe any manufacturer would knowingly release a product with this amount of buzzing. I can easily hear it from my seat, which is 14' across the room. What's more, it's a dynamic buzz -- it varies in amplitude with the amount of white in the picture (I guess the more white, the more current being passed to the pixels); so, I can't just tune the buzz out like white noise, because everytime it recedes in my consciousness, a bright shot will appear on screen and the buzz will reassert itself.
Has anyone else experienced this kind of buzz, and had it eliminated by replacing a circuit board or power supply? I love the picture, but don't think I can live with the buzz in the longrun.
BTW, I haven't noticed any buzz coming from the panels of any other manufacturer's sets (and I've listened to a lot in the last few days). I wonder if this has anything to do with the fact Pioneer uses only one pane of glass in their panels, while others use two (which may work like dual-paned windows in this application).
