Receiver: slight noise/warm = normal ?

[dcowboy7]

question: even when my receiver has been off awhile it makes a slight whistling noise and stays a little warm...i just never noticed it before so can someone please confirm for me that this is normal which im thinking it is....thanks.

Unless you physically unplug the receiver it never shuts off. The receiver is always downloading programming information so it never completely shuts down.
