ahoch,

My initial response did not address the second issue which you had reported (i.e. sonar and radar not functioning). Should the fishfinder transducer and Digital Radar Cable have been interfaced directly to the problematic MFD, then the problem reported with the symptomatic MFD may be more extensive than simply its backlighting circuit. Should the fishfinder transducer and Digital Radar Cable be interfaced to the system in some other manner (ex. via CP370, via HS5 RayNet Network Switch) then please respond accordingly.
