Hi Strangeways this is a learning curve I have reseated all connectors numerous times checked for cracked solder on pins found 2 reflowed those pins no difference. Its amazing that I get the game working 99% then 1 problem occurs and snowballs.Am I right in assuming that every board needs repining and new connectors.

Not always - you just need to narrow it down. for example - if the playfield lights are playing up, then you can jiggle the Lamp Driver connectors until you isolate the faulty lamps. Clean the connector pins with some sandpaper 400 Grit and then refit. That will confirm the problem is THAT connector. Replace the connector and pins and then see how you go.
