Hello, My LED control went blank on me when I pushed the jet/light button and now the spa is disabled. I have power to the control box, no fuses blown, and there is no reset switch anywhere to be found. This is a Balboa topside control with a telephone type jack that plugs into the circuit board. Is there anyway to test this thing? I'd hate to spend $100 on a new one and find out its something else. Comments would be greatly appreciated. Thanks!
