I am having a problem with my Flintstones pinball where the memory is not holding on occassion after the machine is turned off. It is not all the time and only happens on occassion.
I have recently replaced the battery and reflowed the solder joints on all of the connectors. It did improve for a around 3-4 weeks although I am now experiencing the same issue.
I am not sure where to look next, has anyone else had the same problem.
