I have visited the Headquarters Beercade river north location in Chicago and noticed that their Addams Family pinball machine with ColorDMD is flickering, hard to read, and letters coming in and out, etc. The Headquarters Beercade location off of Sheffield had a Theater of Magic that had the same symptoms with their Color DMD display. Is this a common problem or perhaps there were some loose connections with their displays in their machines? I'm in the market for a Color DMD display for my Addams Family pinball machine and was hesitant on getting one due to the problems I'm seeing on those machines. Has anyone else seen this issue with these displays? Thanks!
