How to fix a blank LCD display on a Rain Bird Irrigation System?

What to do if the Rain Bird Irrigation System LCD display is frozen?
If your Rain Bird Irrigation System's LCD display is frozen and the controller isn't accepting programming, an electrical surge may have damaged the controller's electronics. Unplug the controller for 3 minutes, then plug it back in. If there is no permanent damage, the controller should accept programming and resume normal operation.
Why won't my Rain Bird Control Unit start watering automatically or manually?
There are several reasons why your Rain Bird Control Unit might not be starting. First, ensure your main water line and all supply lines are open and working. Verify all field wires and master valve/pump start relay wiring are correctly connected. Check for any broken, cut, or 'skinned' wires, and replace them if needed, along with ensuring all wire connections are watertight. Make sure the dial is set to the AUTO position. If you have a Rain Sensor, it may be activated; wait for it to dry or disconnect it and connect the two yellow terminals with a wire. If you don't have a Rain Sensor, ensure the wire connecting the two yellow terminals is intact. Finally, an electrical surge might have occurred; press the reset button under the wiring cover to see if it resolves the issue.
