The 2465B has a separate CURSOR 0 line, but DLY REF 1 is shared. I think
this was done to allow cursors under delay sweeps. I'd guess DLY REF 0
controls the B-sweep timing, so I'd take a gander in your shoes.

DLY REF 0/1 also control the position of the vertical cursors, right?
These function just fine, so I don't think it's these control lines.

I also remember a case where a decoupling capacitor on the mainboard side
of one of the A5 control lines went leaky and pulled the control signal
down.
