Just a guess, could the Auto Timing cap C300 at pin 6 be leaking?

Pin 6 goes high when auto with no trigger is selected, so that appears to be fine. I've traced it as far as the sweep gate signal going to pin 3 of U380. From there it gets complicated because things connect to other boards, and no voltages or waveforms are given on the schematic.
