Radio Problem on FRC

[TuaMater]

Our team just started having serious radio problems tonight. Basically, when we plug the radio into the FRC, no lights come on the radio itself, and it doesn't respond, and we get the corresponding red light on the mainboard of the FRC. When we tether the RC and OI together the code executes fine and life is happy. In addition, when we plug in the radio for the RC into the OI port, we get the Standby light on the RC radio. However, when we plug the OI radio into the FRC radio port, we get nothing again. This would leave me to believe that there's an issue with the Radio port on the RC, but I have no idea how to fix this short of getting a new RC. Any ideas from anyone here?
