I have not had an issue with mine but I would check to see if you have voltage going to the feedback potentiometers first. That supply would have both az and el in common. Mike

After Sitting for 6 months my rotor is acting up. It was working 100 % When I left for the winter. Big issue is it isn't displaying any AZ EL data on the display, and appears to be sending bad data the the LVBTracker. The rotor operates manually but there is no AZ EL data displayed. When I try to track a sat with SatPC32  it seems that that the 5500 is also sending bad data to the LVBTracker as the antenna EL runs away , and the AZ data is also way off. So my question is did anyone also have this issue? I'm thinking it's in the control box as bot AZ and EL are affected. As I can't see the antenna from my operating position I'm off the sats until I can fix this. Any help would be greatly appreciated.
