Richdel 508PR problem

Yesterday our Richdel 508 PR controller was working fine. Today, when I wanted to manually run Zone 5, it wouldn't run (no water running to zone). I tried Zone 7, it works, heads pop, ditto Zone 2.
Zone 4 & 1 are also not working on the manual setting. (currently, we aren't running Zone 3 & 6 as they need repairs)
Any thoughts as to why some zones are working on the manual setting and others aren't? First time this has ever happened. System is 27 yo.

Typically, when several zones suddenly stop working I think wiring issue. As old as your system is it could be a timer or a valve issue. If you take one of the wires from a working zone and move it to the controller port for a nonworking zone you'll be able to tell whether or not the controller is the problem. Probably time for an update anyway.
