[LW] [LW11] Radar overlay stopped working

[[email protected]]

Hi with original Quantum 2 dome had rada overlay working on chart. Now trying a new Quantum 2 dome to try and resolve a different issue I have with radar being disconnected when motoring after about 1 to 3 hrs see different thread.
But with the radar installed not seeing radar overlay anymore.on chart settings it shows radar on and range rings on. I see range rings on chart no radar image. Have tried changing range no luck.on my dashboard it shows my heading which is obtained via my Auto pilot

What stupid thing am I missing it use to work at dock
