Hello. I just purchased a 32" Sharp Aquos and I noticed that when the TV is off it makes a slight hum. The sound is not coming from the speakers, but from the vent holes on top. I was just wondering if this is normal? I seared the manual, but it didn't mention anything.

Thanks for any info.

Not sure if it's normal or what, but I have the 32D7U and I don't hear any humming when the set is turned off.
