I have a Quantum radar attached to an ES 128 MFD. Both have the latest updated software installed. The radar is connected to the MFD through the ray cable into the back of the MFD. Unit had been working great since installation but last week I turned it on just to check it and I got a message saying it couldn't find the radar. Restarted both units and same thing. The next day went to boat to check connections etc. but upon powering up, everything seemed to be ok again. Tried using the radar the other day and the radar icon on the MFD shows its connected and the icon is rotating. Also responds to standby and power down commands from MFD. It seems I'm getting little/no data from the radar like it's not rotating. I had a boat a close distance in front of me and also tried heading straight to a buoy, but I never received a target on the screen. It usually picks them out with no trouble. Sitting in the slip at the marina, the screen is usually almost completely red, but I'm getting very few returns on the screen. Can anyone advise?
