OK cheers. Pulled out the battery, goes in audit mode but the advance button does not work in any circumstance. I can still play the thing at least but flippers are lousy and the settings aren't great, (also set with no background sound) which is a bummer, you would not think it makes that much difference.

First things first i'm going to repair the 40pin interconnect, rebuild flippers, then just generally go over the whole bloody thing and check whatever has to be checked. Thanks ddstoys for the message i'll check it out tonight. I have to be honest learning to fix these things is just as much fun as playing them.

Cheers.
