Check other inputs AVI, HDMI,,
do you here the hum on all inputs?
The hum maybe from a bad ground loop,, unplug all pluged in inputs, [dvd,games,radio,ect] <--check for hum.
If the hum is gone, plug inputs back in one at a time and test,,
When you find the source of the hum, go get a ground loop isolator to fix.

If you are using a cablebox, try adjusting the audio settings in the cablebox menu. I've seen this alot when the cablebox audio is low due to these settings. If you are turning up the volume past half way to hear it well, this is most likely the problem. I hope this was of some assistance.
