We just had a severe thunderstorm come through and now there is no display/power to my Aqua Trol system. The timer works but that is all. I have used the diagnostics from https://images.inyopools.com/cloud/d...ting-guide.pdf Everything checks out down to page 11 step H. There is a test for 3 to 5 VDC to pin 1 & 3 to the display board. I have no voltage. Is there other test for the main board that I could try or just change the board? There are no spots on the board that look bad/burned and the voltage limiting resistor looks good.
