Studio Spot 575 Pan Tilt Logic board issue!

Hi everyone,

Having a problem with a SS 575 zoom fixture. The pan and tilt functions are not working with no motor movement at all. To avoid any confusion here is were i am at with the fixture.

1. I have tested all motors and sensors.
2. I swapped a logic board out of a fix and all functions are working so i have boiled it down to a logic board issue. I really don't want to have to drop $$$$ to get a new board so if anyone has a suggestion on what may be wrong with this board I would greatly appreciate it.

Thanks!
