take the cartridge off and blow hard down the tonearm(no homo).
peace, stein. . .

make sure the ground connection is decent, and that there is a u-clip on the end of your ground wire (wrapping frayed wires around the ground post on your mixer sucks).
check tonearm cleanlieness, cartridge connections (none should be touching each other) before taking it apart. If you can't figure it out, it's either the tonearm pc-board or the ground wire solder point. If you don't feel comfortable taking that stuff apart, shop is probably your best option.
