Sounds like an amp problem, rather than the FBV. First thing would be to try a factory reset of the amp - hold the 'A' button in while turning on the power, and hold the button in for another 5-8 seconds. Be sure to back up all your user preset toness with Spider Edit before doing this.
If this doesn't cure the problem, you can try reflashing the memory. If that doesn't work, then the amp will need to go to a factory service center for evaluation.

+1 to fflbrgst.
Instructions on how to reflash the amp are available at the link below:
If the factory reset and the reflash procedure did not solve the problem, then the amp will need to be assessed for repair by a Line 6 Service Center. To locate one in your area follow the link below:
