Examine your answers
Yes, to questions 1 and 2
If the answers to questions one and two are yes, it’s likely
that one of your sources (CD player, turntable, video feed),
is the cause of hum. Remove that piece from the receiver,
amplifier, or integrated and the system hum should now
be gone.
Once identified you can either replace that piece of gear
or read our extended hum fixing guide found here:

hum-extended/
Yes, to question 3
If steps 1 and 2 were “no”, but removing all inputs
eliminates the hum, it is likely you have what is called a
ground loop.
Ground loops are common when video equipment is
connected. In particular, a cable TV connection.
Reconnect each source again, one at a time and listen
for the hum to return. The offending piece of equipment
will show itself when you follow this procedure.
