Versa 2.3 Control Box. Dead

Will not switch on and run table motor. All LEDs including power stay off. AC in and fuse are OK. Compressor air pressure levels and routing to air bearing arm and platter are good. Any help greatly appreciated.
Could it be that the turntable motor itself is dead?

Opened the control box and cleaned connections. No change.
Did a little testing with the multimeter on the control box.
There is some kind of filter on the dc output which is the input to the motor. The input to the filter measures 0.5v and the output measures 0v (???)
Does this sound right?
