HP 55 Bad Key Row



#3

My HP 55's last key row ("divide","0",".","R/S") suddenly started acting like the Enter key row ("ENTER","CHS","EEX","CLS")
Any suggestions?

Thanks, Ed


#4

It sounds like you have a short between the traces between those rows on the pcb board. I would take it apart and see if there is some contaminant causing the problem.
