Harvey,
Is he getting a sweep? The video does not show a working sweep.
The complete lack of sweep looks a lot like the failure I saw on my dad's 475, but the timing board on the 465 is a very different layout (e.g. I don't see any of the big axial caps that are so in-your-face on the 475 sweep board). The failed component for me was a smaller silver axial electrolytic cap (C1059), that looked a lot like the timing caps, but turned out to be just a decoupling cap on the +110V rail.
I still don't understand how the failure of that decoupling cap brought down the whole sweep circuit. It wasn't shorted to ground, so it probably wasn't pulling the +110V rail down, but it brought the whole sweep to a dead stop. All I had was the spot sitting in the center of the screen, no matter what I did with the TIME/DIV switch (I don't think I tried putting it in X-Y mode: it might have responded correctly to that).
So that suggests something else that could be tried in this case: put the scope in X-Y mode and see if you can move the spot horizontally by applying a signal on CH 1.
