Trimble fm 1000 /DCM 300 problem

[Niteforce]

Looking for help on this one
Got a fm1000/dcm 300 running RTK VRS.
All been working fine until tractor went in for a new clutch. Nothing touched in cab during job just all cables disconnected from batteries. Got tractor back and now screen cannot find dcm just saying searching all time and " no dcm".
Checked all power cables and seems ok , new USB splitter , still no joy . Seems very odd to me but could just be coincidence that something else has gone wrong at same time as tractor being repaired. Any suggestions welcome.!!

If DCM is the problem then I have a used one I'd part with for a reasonable price.

Has the DCM got power? Is the led lit up?

Yes it's got power
Green light flashing 1 second on 1 second off

DCM was connected to the correct connector on the FM1000
