Don't stress Marty - All these games have small issues - and that's what they turn out to be = "Small issues"..
If I had the schematic in front of me - I could help you out a bit better. You problem is with the row or column that the flippers and spinner is in. Look at the schematic for the switch matrix - "read" each switch and follow the wire guide and the orientation of the diode in respect to the switch physically... It could be a bad diode on that row, or a switch that is not wired correctly.. Also, check that each switch lug is not touching anything like a light socket etc..
