My GX 50 display goes blank and the Cerbo-s GX stops responding disconnecting the power causes a reboot and the pair are up and running again. I saw several posts in the group with similar problems but no solution. Thinking that the USB may occasionally be drawing too much current I connected the USB to a source from the batteries. The problem persists. We are presently traveling in Labrador and Newfoundland so communications are poor and battery power is critical. Victron support has been a disappointment taking a week to respond and offering no troubleshooting or fix solutions. We will have WIFI for 2 more days so any suggestions would be appreciated.
