I am an older Gentleman that purchased a 'Bally Pool Sharks' pinball machine. The machine has worked perfect for the last month. When purchased I was told the lock for the back box was bad, everything else was fine. So today I changed the lock (I like all things to be right) and while in the back box I changed the batteries out. (batteries have been moved from the board to a remote holder!) I left the machine plugged in, but not turned on. When I buttoned everything back up and turned it on I got the message Adjustment Failure. I have the manuals for the machine BUT, not wanting to screw anything else up I thought I would ask for advice from you folks on the forum. Any help would really be appreciated. Gary

Thank you guys for your info. Being new (to me) I panicked! Followed the instructions and it is back as before. Greatly appreciated!! Gary
