The Radio Information Board

Radio was working fine then got really loud, then "Rx Bk Fail" showed up on screen. Couldn't find anything online regarding error, anyone here have this one before? Don't have much experience with troubleshooting them, just programming.

Model is 242-5117-660GS4, VHF

that is most likely a flex strip issue between the logic and the RF. For whatever the reason the logic cannot read the RF board settings. You can try giving it few smacks and see if it will re-seat itself a little better. Later on they changed that error message from rx_bk_fail to Cycle_Power
