I have a 30" NEC display. I've noticed that there is a buzzing noise .... not loud enough to be an annoyance. But none-the-less, it's a new noise. If I hold my ear over the top of the monitor, I can hear it. I assume that it's coming from the power supply, but can't be sure (I'm not a technician). It's not loud enough to be an annoyance, but I am concerned that it might signal a downturn in the unit.
Ideas or comments?
