TV Humming Sounds

[Nanometer]

I brought home a 46" Insignia LCD LED tv the other day, and it has a constant humming noise coming from somewhere near the power supply I believe. This normal you guys think? It's too loud for me to live with it =-(

Never heard of an LCD......but yah our old plasma does buzz, when the volume is low it's noticeable. DLP FTW!

If I do anything with a 60 hz feed I can hear it, anything lower there's no noise. Maybe it's an insignia thing haha

Contrast to high can cause humming in speakers and such,find a balance.

It isn't the speakers
