So my RS4 the lcd display went out, but the display still has backlights, and red light for the filter pump is on but the unit is not responding or sending a signal to the pool. I've had zeros issues with it until now. Is this just a pcb board replacement type thing? If so any recs on where I can source. I"m not scared to unscrew and rescrew 4 wires.
Thank you for your help.
