I don't know of anybody who repairs those but you could ask at your local irrigation supply store such as Ewing. You should try unplugging the timer for 5 minutes to see if it will reset things. Make sure you take out the back up battery. You don't have any contact information so I can't email you with info where to get a new one. There's only one available. Better hurry. Or replace it with a reliable timer such as the Hunter SRC.
If I can't fix it, it's broken!
