Question
Our RD-1200's LCD display is blank (no power). I confirmed that it's getting 24VAC to the controller terminals. I looked up the user guide on-line (Rain Bird) which indicates that it might be a blown fuse, but my circuit board doesn't have a fuse! It appears that the Hardie model did not, but the Irritrol model of the same thing (also RD-1200) does - presumably they bough Hardie and upgraded the board design? In any event, is this fixable without buying a whole new controller? Thanks!

Answer
Not unless you are handy with electronic repairs.  Sometimes the boards go out, and there is little recourse but to either have it repaired, or replaced.  Try resetting the controller before you replace it, byt removing all power (including the battery) for 3 minutes, and then reconnect the power.  Otherwise, it is probably cheaper to replace it than to have it repaired.
