Hayward Salt System - no power / lights

I have a Hayward Aqua-Rite system. Recently, I lost chlorine production and found that there are no lights on the LCD/LED display. I ran the Aqua Rite diagnostics and passed all the way to step “H” which is replace the DSP board. Does anyone else have a suggestion before I search the earth for a replacement board and pay a lot of money? Pic’s included.
