I have a 27" imac. The screen is making a hissing noise that seems to get worse as I brighten the screen. Any thoughts?

I have a 27 inch Imac that is making a noise that gets worse as I increase the screen brightness. Any thoughts?

Did you resolve this issue? My iMac 27 just started making an irritating noise that decreases/increases when I lower/higher the brightness. The noise also increases when i scroll documets and webpages.
