When I turn on my c120 Classic MFD (purchased in 2007 and still using the original DSM) the radar comes up with "No Data Source" then after about 10 seconds its says "Scanner Warm Up" then about 10 seconds after that it says "Checking HW" and another 10 seconds back to "Scanner Warm Up". Once the scanner completes its warm up I put the radar in TX mode and can not pick anything up. If I adjust the gain to 100% it just washes out the screen. The radar is spinning but not receiving any data. All waypoints show up. If I enter a waypoint it highlights it. Batteries are fully charged. My software version is 3.18. Never updated because everything worked fine. Any ideas? Thanks in advance.
