SOURCE: Sprinkler control box appears fine, but sprinklers to not open
If all zones do not open, I would check the water supply first. Verify that the water is indeed on. If you have water at each valve location, then I would check at the wiring at the controller. Use a Multi-meter & check the resistance (ohms) between the common wire terminal and the wires at the terminal for zones 1 through 6. If you get an open loop (O.L.) reading on all zones, I would think the common wire is cut or disconnected. Also look for a rain sensor that could be wired into the common wire. If it is faulty or stuck, it could cause an O.L. in the wiring. If a rain sensor is wired in at the controller, disconnect it from the common wire path and connect the common wire directly back to the common terminal. If it works now, then you have a bad rain sensor.
A normal reading should be 20 – 60 Ohms from the common terminal to any zone wire. If you are in that range, the only other thing it can be is the output voltage from the controller to the valves. Use a Multi-meter & check the voltage at 24VAC terminals where the external transformer is connected. You should have 24-30VAC. Next, open zone 1 and check the voltage between the common wire terminal and the terminal for zone 1. You should have the same reading as you got for the transformer. If you have nothing or a large difference, then I would suspect the controller might be damaged.
Remove the power & 3 volt lithium battery and wait 2-3 minutes, then reprogram the controller and try again. Good luck!
SOURCE: sprinkler head does not spray water
Make sure when you pull the head to ck the screen you turn the system on and blow out the line, then run a hose through the head to make sure it isn't plugged up anyway. Depending on the head and the cost of a new one will dictate cleaning or replacement.
SOURCE: We had "Power Off" failure

Your manual is above.
Now that Power failure you had, maybe have an underlying problem, First you need to try and reset the unit, as per the manual, and try resetting up the program parameters again, and seeing if it would then work? Right, now if it still will not work, after doing this, then I am afraid that the Power Supply switching semiconductor devices, that drive the solenoids that open the valves that let the water flow, are damaged, that, or the Power supply, has failed in the section that supplies the extra current to drive the valves. or, It simply may have suffered a power spike? and this also would account for symptoms such as these, too.
If it is proved to be internally faulty, you really have no alternative but to return it to the manufacturer for repair, as you will most likely need to replace the driver board.
SOURCE: Rain Bird sprinkler timer blowing fuses
Disconnect all zone wires and see if timer blows fuses. If not, one of the zone valves is drawing too much amperage.
SOURCE: Automatic sprinklers (Intermatic timer) do not
If manual override works, and dial rotates on time each 24-hours, then worn trippers are suspect.
