Plx 500 motor

So I ordered a pair of the PLX 500's with cases about a month ago. Unboxed them, played with them..generally stoked. I go to practice on them today and the platter on the left table has stopped working. Checked EVERY possibility..power on because the lights are all on, can switch from 33 to 45 and back, but when I press start/stop..the platter doesn't spin .
