Not sure if this is the proper forum or not. If it is I apologize. Our church uses this old beast for our lighting. We turn it off after every service and it's worked rather well for 26 years. The last couple of weeks we've come in and turned it on and it's lost all our show programming. Is there a battery in there that's finally died? Some type of memory gone bad? Any explanation? We're at the point of just leaving it on 24 x 7 now until we figure out how to fix or if we need to replace it.
