Through with Buzz.

My turntable has just started creating an obnoxious buzz. Maybe you can help me fix it.

When I lift the arm, and the motor fires up, there is a loud buzz coming through the speakers. The sound stops at different times, but usually in the amount of time it takes for me to lower the needle to the record. Sometimes less time, sometimes more. When the record is over, and the arm is automatically lifted and dropped into the arm holder, the buzz comes back between when the arm is dropped and when the motor stops. If it weren't so loud, I wouldn't care, but man is it obnoxious.

I checked all connections, and they are secure.

Any ideas? Or should I just bring it to the shop?

The player is a Pioneer PL15d-II if that matters.

Thanks.
