I recently inherited a board for the sudden laps of the person who worked it before me at my local church, I know it has been through a few people and has a lot of issues, one of my biggest ones is that buttons like [blind] and [M1] on my board are in responsive or always have the light on. I can access them through the visualization software, is there any way I can get them to work? Is it that they are broken or is it a communication error between the board?
