Few Baseline Questions to ask:
1)What language are you using?
2)Are the lights on the victors solid when you enable it?
3)Is the Digital Sidecar receiving power?
4)Are the PWM wires plugged into the correct slots?
5)Also with whatever you are using to control the robot(controller/gamepad/joystick etc.), is it numbered as in when you open up the driverstation and go to the status/diagnostic page(don't remember which one offhand) is that controller in slot 1(or whichever value you are setting your controller as in the code) in the table on the right hand side?

(I can't say anything about Talons, I have not worked with them.)

If the Victor lights are solid when the robot is enabled, then it is receiving a signal and its a problem where the value you are sending from your controller is not setting the victor values.
