I have a 2012 C90W connected to AIS
and the usual ST70 tridata instruments and autopilot
(ST6002) which has worked perfectly for the last two years. Suddenly it has decided on startup to display the Raymarine
as normal but when it would normally ask for agreement the display goes dark. I suspect it may be still on as to recover the welcome screen
I need to hold the power button down for 5 seconds (normal shutdown procedure) and then press the on button for the same result earlier described, Any help would be appreciated.
