Church volunteer needs tech help please

edwardbarnett

                    Hi, I volunteered to help my church with the light board RH3 after the person that set it all up left for another opportunity. So, everything is simple but left as is. Recently slider 7 that controls a light over our cross disables or severely limits the other 6 sliders and those light fixtures. I’m reading the manual but also have no experience and I’d like to fix this. I’m not sure if I can do s reboot or program a new setup to fix this or if it’s a wiring problem. They are all single non moving fixtures. Abu guidance or help would be appreciated.
