Yes, screen displays : "no signal", and that's it !
Thanks to on/off buton on the Argon case I can force a reboot, or, alternately when i'm lucky, open a new console with VNC on a phone or tablet to force a reboot ...
In that case I can see that OpenCPN is still alive, and we know weird things happen when the machine is rebooted while openCPN is running ...
All this is a drawback to usual OP reliability and excellent stability...
It seems the HDMI is quite sensitive to power condition.
I used a 3A 5V supply, I changed it for a TOBSUN module 12/24VDC to 5V 5A, 25 W, and never saw anymore the under-voltage symbol !
I just added today an output capacitor 440 µF to try to improve the things... I will inform back if any change ...
