I have recently purchased a DELL 30" LCD (3007WFP) Rev A02. When it's on, it emits a buzz from it's top right back. The buzz grows as the brightness is decreased. The buzz is similar to the one a neon starter emits.

DELL was very good at quickly shipping me a replacement unit, but unfortunately, it makes a bigger buzz.

Is there a quiet 3007WFP out there? Please share your experiences. I see no value in getting more replacements unless the problem has been identified and fixed.
