find the zone valve that feeds those stuck-on sprinklers, and repair or replace it

Hopefully, the zone valves are under a green plastic access cover for you to find. If not, then the cheapo solution is to follow the wire from the controller to the valves. The pro solution is to follow the wire with a cable locator (you can rent one)

Another just-in-case idea is to disconnect the one wire that feeds the faulty zone, which would point out a rare controller fault that continuously energizes one zone.

Wet boots is exactly right.

If you don't have a locator to trace the wires you may use what is called "chatter/ pinging" the valve. Basically your using low voltage electricity to make the solenoid open and close, this makes a clicking noise.

If you don't have a Station Master there is a cheap cheat.
Make sure the water supply is turned off.
Disconnect the station wire from the controller.
Turn on the station on the controller.
Have someone tap the wire on the terminal while you are in the yard listening for a clicking noise.
You will have to listen very closely as some valves are louder than others. Over the years I have noticed that dogs hear the click noise a lot better than we do.
Then replace the faulty valve.

Just be careful not to touch the terminal, you might get a slight buzz. Low voltage.

However the valve locator is the best way to go. Our company charges about $45 to locate a valve. I'm sure there are companies in you area that will offer the same service.

Or just rent the locator and battle the leading cure.
