plasma tvs buzz a lot, depending on screen brightness. its probably normal but if you can hear loudly over your volume, may be a bad board or plasma panel. from behind tv, left side = y board, right side = z board, middle = power board ---- bad panel can buzz from anywhere... if you hear all parts buzzing, its probably normal plasma noise

It the colors wheel,the fan don't make that much loud of a noise.When the colors wheel spins off it axis it make very loud squizzing and buzzing noises.

Hai,
Buzzing can be caused by a bad ballast, colorwheel, or cooling fan... Nothing else makes a noise, unless it's comming from you speaker.

Hope it Helped U!

sounds like the color wheel needs to be replaced very easy repair on that model Samsung.

that's a failure about to happen in your video control circuit board..you feeling like you want to dig into this yourself, or does this have a warranty

I have the same problem I can hear buzzing over the volume of the tv into the 30 range. I've had a tech out 3 times and he's coming out for a fourth. He's changed to power supplies and is bringing the 3rd next visit. From what I've read it has either to do with power supplies or grounding strips.
