A problem just started a few days ago

I can hear line hum in the tuner, AM and FM.

The hum is real loud when I turn on the receiver in the morning when it's
cold but the the hum is minimal after the receiver has been on for a while,
which is why I think it's a heat related problem. I can still hear the line
hum if I listen closely, though. The line hum was never there but until a
few days ago.

I can only hear line hum when listen to the tuner, all the other sources
(CD/AUX/Tape 1/Tape 2) are fine.

Is this a normal or is this a problem which requires repair?

I think it might be a capacitor or something.
