[CA] [CA11] RD218 passes all diagnostics but shows no image on c120

Ok, done, reset scanner. This is odd. I think I've fixed it (had to cut and reconnect all cables in the scanner cable, where it connects with the scanner, as the solder was brittle and coming apart), and now I have a normal looking image, both on c120 and rl70c. C120 diagnostics are all still passed, but rl70c diagnostics are registering fails on cable test status, receiver supply 12v, receiver supply -5.9v, receiver supply 5v and IF tuned. Both mfd's seem to show working radar, though. Is it ok just to ignore these fails, and hope for the best? (The rl70c is my boat system).
