The good news is that you have a CFTBL and Fish Tails, that have similar boards to Addams Family (WPC89 DMD Fliptronics II). Which will make it easier to diagnose the problem, if it is a board or connector problem. I hope someone flies to your aid. I assume you have spares of certain wear parts, critical to any repair. I could not imagine flying with a tool box, VOM meter, logic probe, soldering iron, etc. to Hawaii in my suitcase.
