Turntable Hummmm

Suddenly, without anything being touched on my system, I have a hum coming out of the speakers when the stylus hits the vinyl. Its not real loud but it is there. I've disconnected everything and reconnected and it is still there. Any ideas how to find the culprit?

Meant to note that the hum does not appear during CD playback.

I am using a Rega P25 with an Exact 2 cart. The cart is 6 weeks old and has sounded great. The P25 does not have a ground.

The hum occurs only when the stylus is in contact with the LP.

What is a ground lift plug? Thanks for the input.

Did not disconnect the cart tags but will now. And I can swap carts if that does not work. Bummer.

Problem solved! Disconnected the 4 cart tags. One of them was not very tight so I took M. Fremer's tip and placed a toothpick in the tag and squeezed it with needle nose pliers. This tightened the connection. Hooked it all back up and the hum is gone. Thanks for your help on this irritating problem.
