These harmonica connectors plug into a dual in-line connector which is numbered 1-60. They were all unplugged and in disarray when I opened the scope up. None of the lights light up on the vertical and horizontal mode selector switches or the left right switches.It's possible that someone tried to diagnose a short in the frame by
removing all the connectors. I'd check the supply voltages before I
close it up.
