Cannot find in manual how to clear code. It was fine yesterday showing everything. Tried disconnecting at box and it did nothing. Error code in book show no error but I have no other readings. Checked battery state in panel and it showed good

Unfortunately, it appears your image doesn’t show on this end.
Is there any activity in the control at all? Lights maybe?
Is there any chance, someone has disconnect wires recently and miswired it? Could the polarity be reversed somewhere?
Does the battery to controller circuit have any fuse protection in it that could be blown?

Bryan I don’t know if moved some wires when I cleaned up hydraulic fluid that leaked around every fitting on top of hydraulic pump. I put a the tester on pv connection and showed 36 v if I did it right. The wires are a mess in battery compartment so I don’t know if there is a fuse.

I turned off the solar and battery switch not at box. Could I disconnect wires at screws on front of terminal to try reset rather dig around battery? I did not disconnect any wires earlier. I am not very experienced with electricity.

Can I ask for a picture of the wire connections on the bottom of the controller? It would seem that you have power given you have two lights on and the display is showing EO.
Would you happen to have the blue tooth app? If so, could you share photos of the screens and settings?
Did you check the buttons to ensure none are stuck down?

I am not very experienced with electricity.maybe it happened 2 days ago as I did aurto hitch and re auto level. To get rid of suction noises. Which has worked so far. .it happened after that

Have you tried arrowing down to see if the screen changes values?

I really don’t think anything is wrong with your display. Read thru the manual, the sections on settings and troubleshooting should get you back on track.
