opencockpits multi-radio not working

[michaelnysus]

Blessings,
My opencockpits multi-radio has stopped working. Great little unit.
Opencockpits owe me money and don't answer my emails. It blinks on and off, registers then doesn't. over and over. Do you possibly have a circuit diagram ? or suggestions ?
Thanks :cry:

I'm sure they will reply to your emails, often they need more time for reply, but usually they do :-)
