Re: Servo Example on LabVIEW -- assistance, please.
One diagnostic is to try manually turning the servo shaft. If the servo has power, it will resist disturbances and return to the previous state; telling you that the breakout, jumper, and other electrical elements are working. Also, unplugging the PWM, rotating the shaft to a new location and replugging the PWM, you should see the servo going back to the same position.

If these work as expected, it is a SW issue. It may be useful to see what value the servo is moving to. If pegged on either end, it could be a units issue. I believe there used to be two servo units, an integer input meaning degrees, and function took 0 to 1. Vary the input to the servo function anyway and see if any of them work.
