I recently bought a Hitachi 36udx10sa, which is a tube tv and notice there is a slight buzz/hum sound coming from the back of the tube. It is not from the speakers. It is very low, I can't here it if I am in front of the tv even when the volume is off so it is not bothersome. But this is my first large tv and wondered how much sound is normal.
