If it is the controller board then most likely you wouldn't see this issue on all ports since most boards have almost nothing in common from the circuit point of view, except the power lines.
Hopefully the system is accessible for you to check with a mulitmeter and measure what's going on, but my bet is on the psu. Capacitors have in many cases a very limited life.

Sorry, I should have posted more details about the hardware.
OpenPrinkler PI
RaspberryPI 2B
Orbit 24 VAC 750 mA Transformer
I just ordered a new Transformer, to see if that solves it or not.
