Got a few hours spare yesterday and sorted out all problems
Resflowing all solder joints on IC U2 seems to have fixed Things flipper and Beaky was spot on with the right top flipper, connector adjacent to flipper button was open cct temporarily bridged and now working fine only other problem was one power magnet was down to 1 ohm resistance and blowing the fuse, disconnected that magnet now ok will add a new magnet to my list to order.
All in all not too much wrong with this machine .
Will add a few photos of the condition soon.
All i have to do now is stop playing it so i can restore it .
Cheers
John
