No light on Hayward aqua Trol

[Welcho]

I have no lights illuminating except the low flow when I turn it on which is typical. The lcd screen is working and here are the read outs starting with salt level 2800, 84,16.3,0.0,50p,-0, AL7, r1.45
I had my water tested at a pool store and of course 0 reading for chlorine, salt was 3000 and ph was a little high. I’m guessing I need to replace the motherboard but which one, on the door it has listed AQ-TROL-RJ, do I just find one that is suitable for that?
