Got my 24" 3.06GHz iMac yesterday eve and have already posted about the backlight bleed issues.....wondered if any new owners have noticed the inverter buzzing? Its quiet on minimum brightness (but then the left to right gradient issue is very obvious) but as you increase the brightness the buzzing gets more and more loud. When the brightness is on max it becomes quiet again for a while but starts buzzing again after a few seconds....moving the mouse or changing image silences it again for a while but the buzzing always returns. All the issues I have had with these machines centre around the screen bleed and now inverter noise. I shall return this unit tomorrow and see if I have any more luck with a new one. The iMac is the only all in one on the market that fits the bill for me so I seem to be stuck in a loop hunting for a decent one! Has anyone else noticed this noise from there new 3.06GHz iMac? Cheers
