Your symptom is almost always caused by pin 1 of the connector on the analog board for the cable which connects the logic board and the analog board. So look at the logic board (it has fewer cables). Find the cable that connects it to the analog board. Look at that connector on the analog board. You'll need to remove the cardboard cover. Pin 1 is the one by itself on the other side of the blank position. IIRC. it is also the pin closest to the front of the machine. Desolder and resolder pin 1. The cardboard cover was held on by double sided sticky foam. You can buy the stuff in 3" strips at Radio Shack, or you could many years ago. Clean off the old before applying the new.
