These often fail; the most common failure is caused by overheated terminations. There's very little inside the unit and they are normally repairable. Dismantle the unit taking care not to break anything as you ease the inner parts out of the casing. If it has failed through overheated cables a simple re-soldering job with better wire should have it running fine again.

Presumably you used a multimeter to establish there's no power output? It might be worth checking the switch and potentiometer on the end of the ribbon cable with the meter and that the ribbon cable is secure at each end. And if you're handy with a soldering iron, the switch is susceptible to dry joints.

If it turns out the controller is at fault you might get a second-hand one cheaper from Douglas Valley or from Bell Hill.
