The timer can be reset to factory defaults by 'clearing program memory' following steps in manual.
Warranty period is 1 year protection against defects in workmanship, which is standard for timers from Woods to Intermatic to GE etc.
If the display is not working, and zone does not show, then that implies internal defect, or lack of power. Resetting timer might repair problem.
The timer has electro-magnetic relays, and not an internal solenoid.
The timer turns ON or turns OFF electric power to the water valves.
Water valves have solenoids that open and close when power from timer arrives at each zone.
The solenoid can make the sound you describe, but the timer relays with make small click sound as the electromagnetic relay opens and closes.
In addition to resetting timer to factory defaults, and then reprogramming you might try changing wires to different terminals.
Also the timer works on 24Volt AC transformer that plugs into outlet. It is possible to get display errors on timers when voltage is incorrect, or outlet and transformer are not connected well. Test outlet with circuit analyzer. Change outlet because outdoor outlets get corroded. Clean blades on transformer plug.
Power surge and other events can damage timers. Nearby lightning strike. Power outage causes surge when power resumes.
There is 24-hour backup battery, but the battery does not appear to be replaceable type and instead is rechargeable or capacitor type backup. So the battery is probably not the problem

I could sure use a video or a photo of how to check with a volt meter.
