Am getting a blue blinking Dynon splash screen on startup of my D100. The associated D120 starts up fine, but I notice all lights remain illuminated on my AP74 panel. This occurs with and without engine running. The units have all got the latest software, the ships battery is over 12V and I have no internal battery in the D100. No history of problems with these units either. What's going on and any workarounds available? Thanks, Mike.
