Ok, more info,

When she went into ball search the offending ball popper coil did not fire. Having said that I have tested the coil and in test mode it works just fine. I'm not sure if thats conflicting but that is definetely what happened as in my frustration I forgot to catch the ball as I lifted the playfield and it ended up taking a tour of the house much to the amusememnt of the ferals. I have just got back from a local repairer having bought the whole transmitter and receiver on their boards and will install them later today as I have to bolt now with a bucket load of stuff to do. The repairer mentioned an IC could be the culprit. How and where do I start there?? For the sake of the exercise I will install these new boards and let you guys know the result.

Cheers and thanks,
