Hi all - I'm new to the board. I have a DIG-220 that seems to be fried. I have power to the unit and the cell is in good shape, but I have no readout and just a blinking red light -- two short, one long, one short. I assume this means something but can't find anything online. I've checked my connections and fuses, all seem fine. Has anyone seen this before? Any suggestions? I've emailed Autopilot and think I'm still under warranty but will take care of it myself if it is something relatively simple and cheap.
